This was the first computer I ever seriously programmed on. You could load values into registers by toggling the switches on the front and hitting 'load'.
But it was smell of these machines almost overwhelmed me. That's how computers are supposed to smell. If you're of a certain age, you know what I'm talking about.
This is a PiDP-11, a functional replica of the 1970s PDP-11, a minicomputer of the 1970s. It is a really nice bliken light machine with a great design.
The replica can be obtained here (in case you are lucky)

The PDP-11 is a series of 16-bit minicomputers sold by Digital Equipment Corporation (DEC) from 1970 into the 1990s, one of a set of products in the Programmed Data Processor (PDP) series. In total, around 600,000 PDP-11s of all models were sold, making it one of DEC's most successful product lines. The PDP-11 is considered by some experts to be the most popular minicomputer.

Eingeführt wurde die PDP-11-Baureihe im Jahr 1970.
Die PDP-11 hat eine Wortbreite von 16 bit. Es werden Einadressbefehle, Zweiadressbefehle und Sprünge unterschieden. Die Adressierung erfolgt jeweils über sechs Bit, wobei die ersten drei Bit für die acht Adressierungsmodi verwendet werden und die letzten drei für die Auswahl eines der acht Register (R0 bis R7). Viele Befehle gibt es als Wortbefehle und als Bytebefehle, das heißt, sie operieren mit 16-Bit- bzw. 8-Bit-Einheiten.

One of my several "sheltered workshops", I occupied over 30 years with ACT Forests, under a number of Directors and bosses.
Mark Edgerley was my first Director, who I met before being hired, and taken out by Ian Gordon to meet some of the staff and Foresters of Stromlo, Pierces Creek, and Kowen.
A history of ACT Forests was written for a web site that never eventuated, in the very early days of the web. Then all the stories were lost in the 2003 fires!
A later Director was Tony Fearnside of FACTA and the Westbourne Woods.
Brian Pratt, of Pratt's Tackle Box, then Graham McKenzie Smith, then some of the redundancies started under the Chief Minister for the ACT, Kate Carnell.
Then Tony Bartlett, when many of the rest of us were made redundant in 2001, during which we had the first fire around Stromlo, then the Forests and most of the ACT was burnt in the 2003 fires!

BACKUP for GMcKS Notes.. 05-08-2019
Draft history of the mapping at ACT Forests by Bill Crowle from July 1971
I arrived at ACT Forests in the Electricity Bldg on London circuit. On 1st July 1971, From the BMR in Dept. of National Development.
Most of my experiences are covered in the Oral History recorded by Brendan O’Keefe.
Mark Edgerley was my first Director, who I met before being hired, I visited him in response to the job ad. I was taken out by Ian Gordon to meet some of
the staff and Foresters of Stromlo, Pierces Creek, and Kowen.
An interesting first week was spent meeting staff and touring the forests with Ian and Kevin Willis.
The Springboks came to Australia under protest, and we were asked by the Minister to build a fence around the Manuka Oval. Then we had an afternoon at the match… I was not political or a football fan!
A history of ACT Forests was written for a web site that never eventuated, in the very early days of the web. The files were stored on the ACT Gov. INTACT system..
Then all the stories where lost in the 2003 fires!
I commenced my days touring the forests with Kevin Willis or Bill Bateman. I sketched a bolster for a truck at Kowen, visited the Assessment Section under Peter Tinson at Forestry House, and met Roger Fenwick, who introduced me to the walk across Civic to the Griffin Centre and the Plan Printing section. Spent many hours there over the years printing various drawings with Joe Costa.
Assessment building was part of the Forest and Timber Bureau in Banks Street.
I observed the many wooden map cabinets or drawers, and few metal drawers with scattered maps over the depots, Assessment Office or HO. Most had been complied by aerial mapping, Radial line plots, and perhaps by the F&TB and 10chains to the inch and some compiled at 40 or 80ch. Usually there was no author, date or other information. This may be checked perhaps in the Map Library at the NLA where I deposited some towards the end of my career…
Met Ron Vivian, of the admin area, to get some maps for him and Roger and later discussed our maps with Mark Edgerley. He asked about getting mapping done by others and keep him up to-date with ideas.. National Mapping approached us for maps and photos covering Gibraltar and Stromlo. This all happened in my first few weeks as I soon got to meet mapping staff from the Interior Survey Branch, the NCDC and National Mapping. We decided to go metric, 1:10,000, for our base mapping, as the P Series were also converting from 1:9,600 ..
26th July 1971, we discussed compartment numbering to incorporate the year of planting, YOP, in the Cpt number, such as 7101 etc, this would extend in sequence across the estate. Thus 71001, Kowen had many in this year.
The Australian Survey Office had produced the P Series maps at 1:9,600 for a number of years before I commenced sorting out the 10 chain to an inch maps existing in the old wooden drawers at House 13 Stromlo or in some drawers at the rear of the Tudor House in Yarralumla where the Assessment crew were based.
I had approval for getting drafting bench, so approached the Dept. Works carpentry section to build one for me to the design of the Dept. National Development’s desks in the BMR, NCDC, and National Mapping etc This took awhile, during which time I worked from my home, where I had a bench and equipment. I was doing mapping and drawings for the ANU and then later Fortech, with Keith Grey and Chris Borough..
Then I became involved in the Area Statement. There was no system for recording mapping or history of each cpt, so I built up and index system with the help of a new temporary assistant, Roslyn Woodyer.
Her initials, RS, appeared on many cards…
ASO
At some later point, the Department of Interior Survey section was amalgamated with the Australian Survey Office, which moved into the new Cameron Offices at Belconnen. I visited them about Air Photos and digitising on 2nd Feb 1990.
Also spent the day getting the PC to go faster with the Autoexc.BAT and Config.SYS files and the Extended Memory. (Not sure which PC!)
More optimizing on the 9th.
Manual mapping systems were still at a high level. We kept abreast of techniques using methods of overlays, colour and screen printing at the BMR, which I used in Vegetation mapping of the Bullen Range for John Hicks, publications for the ANU, such as the Rambles Around Canberra and mining sites.
I checked About photogrammetry and digitising the ACT Forests Plantations and incorporating into my proposed AutoCad mapping system .
I did all my early survey calculations with Log tables and slide rules until ACT Forests purchased a Sharp 363P programmable calculator..
I was using it in Feb. 1973 with 22 programs stored on read and write magnetic strips it came with. See list in my Survey Calcs. Book Vol. One.
Listed in the back cover of Vol One are 50 programs used on the Sharp.
Several programs would write data to a magnetic card to be read from another loaded program. Where you can see the details. (Can’t believe I could write programs for it!)
Survey Branch was used up to 17-10-73, according to p.40
During early 1974 I started thinking about the accuracy and time taken for future Cpt surveys as requested before logging or planting.
An early request for a survey was for the replant of Cpt 1 in Uriarra, which became 73024. (Check) see FB243,244 (thought I had saved these)
See Vol. 1 Calc p91 undated..
Cpts. 43 & 44 Survey, p94 Stromlo dated 6-3-74
All these calcs were performed on the Sharp.
They were carried out using a compass, Abney level and Eslon 100m tape.
I had established during my week long test during Jan. 1974, surveying Cpt 18 Stromlo there was not a significant difference in the Area of the 5h compartment.
I traversed the Cpt. with our portable T12 Wild theodolite, a Wild RDS theodolite from FRI and steel bands or fiberglass Eslon tape. Suunto and Prismatic compasses.. An outline of the method is on p59. A map was plotted with the Areas and accuracy results.
The closing error varied from 1 in 8769, Area, 4.9617ha to 1 in 359 Area 4.953ha p73
Dated 15-3-74 p74 in the Survey Calculations No1.
These last calculations on p74 were re-done on the new HP 97 Programmable Calculator on 14-8-78 Area 4.9585ha with a closing error incl. of 2.55m
Note in home diary, 23-9-80 using the HP67 to do calcs, till it flat!
Launched by HP in 1976...
So we had upgraded by then to the HP97 calculator with 224 steps and 26 memories, or data storage registers, and several flag or Go-to subroutines or loops using the RPN logic system.
This Cpt. 18 was digitised from Air Photo Run 15 Feb 81 #430 on 22-9-81 and plotted on the Bruce Tafe plotter where I was writing digitising and plotting software on the PDP11-34. I was doing a computing course there and also spent many days using their computer, digitiser and plotter.
In conjunction with a Forester, Chris Lacy, who joined us from the NT for a while between postings, he wrote many HP97 routines to solve Areas by Double Longitudes, Heron and Bowditch Closure and correction. (see tag grimwade)
During June-July 1972 I was doing calculations for areas and coordinates to plot on the FRI HP plotter at Yarralumla, which I had free access to.
Some Calculations where produced by the Australian Survey Office, see Bk 1, p31 for Cpt 73028 in Uriarra p33 Cpt 73017 calcs and print out. & Cpt 73031 and 32.. 1973
They were able to digitise Stromlo as a trial.
They plotted a line 2m out from the pine edge around each cpt. I was then able to correlate these boundaries with the P-Series maps to digitise the roads and fences and any other assets.
I mapped all the euc areas, streams etc to produce a cartographic quality map.
I had commenced mapping of regional pine plantations at this time for Fortech, and after a few manual maps during which time I was researching Personal Computers for surveying and mapping.
During 1990-97 I mapped many areas, Glencres, Knapsack, Martins, Hilleast, (This was a manual compilation on drafting film)
Pinebark, Killen, Wyora, Braidwood, Holbrook, Shoalhaven fire regions..
Area
The Legends, Layers, cartographic symbols and standards, evolved with this mapping and that of ACT Forests..
We were leaders in computer mapping and use of Personal Computers.
The IBM and clone 8086 series of PCs came out. I purchased one, 30 July 1987, $3,338, (see Events.xls) for my contract mapping with Fortech at the time AutoCAD 2,5 arrived. The PC needed an 8087 chip for the computational load of AutoCAD so with demonstrations by NEC and DEC PDP11-34 systems at the Bruce TAFE, where I enrolled in a computing course for Basic and Fortran then CAD mapping, I developed software for digitising maps and plantations from Air-photographs and available Cadastral maps. (see below)
On 18-08-87 I discussed CAD mapping standards with Fortech.
I purchased an NEC APCIV AT 80287 during 1987 with AutoCAD 2.52, which progressed through all the versions to AutoCAD 14 and the GIS version AutoCAD Map..
from a README.TXT file on the No2 CD-COPY..
All old drawings from Rel.10 on APC or ASI 386 floppy
moved to Network G: 10/2/95
Hi Graham,
I remember the WS initials on a few drawings that I sorted and filed.
Someone must have commenced all the base maps, on drafting film, most lacked a legend or title block and publishing details and were 10 chain or 20ch to an inch scale.
Some mapping may have been completed by the F&TB before ACT Forests hired a draughtsman. I don't remember adding this information to my index cards, the drawings usually lacked any publication or author details, or reason for creation.
There were some radial line photogrammetry plots that may have been compiled with the help of The Forestry and Timber Bureau. That may be a good source of some historical material..
There was not any system to the maps except for some old wooden drawers for each forest.
I ordered more steel flat drawers and all the Vertiplan map filing cabinets and commenced a map numbering and card index system.
The forest depots also had their own map drawers and a collection of photocopies.
We had a good collection of historical maps from other mapping bodies, it was a shame they were lost in the 2003 fires. I gave many to the National Library before I left, so many are saved!
I have noted some of my mapping experience on the description or in the comments of a few of my Flickr.com images... where I have Backed up these notes…
I seem to remember a mention that Walter was less keen on surveying or going bush, a part of my job that
I relished. I can't remember why he left or retired.

•Transfer my 3M post-it Notes tips and other reference files to Outlook, or similar database for future use.
•Many files on my H:drive, if moved, will upset the paths to the parent files.
• Move H:drive files to G:Drive??
•Translate Aboriginal/Heritage sites to GIS.

•Put hardcopy maps, such as U-200 onto GIS.
•Check all fences against Cadastral boundaries for consistency or errors. Check data with PALM.
•Add fences & gates/grids as assets to GIS with attributes.
Ron Murray asked me to create a database of all the Forests Assets.
We were playing with a new HP 150 desktop computer so I spent a few weeks learning the database Program and entered all our assets like PCs cameras, fences and gates. One week was spent documenting a bug in the software and reporting it to HP.
I don’t think we transferred it to Excel or Lotus 123
There were a few new database in the market at the time, like D-Base MS Works and Enable.
In Jan 1988 I spent ages trying to export attribute data from our ACAD DWGS to import into Enable.
I have a note on Feb 1’ 88 that Mike worked on a surveying software bug. This may have been Mike Archer from NG.. That night I attended a PCUG meeting at the ANU on Microsoft Works.
•What other assets, dams, tanks, culverts, buildings.

This is the desk where I learned (?) digital image processing. The central monitor was connected to a powerful 128x128 bytes video Ram.
Behind the window a gorgeous PDP11/45 with magnetic cores memory was doing the tasks.
Photoshop was simpliy science fiction.
(Project 365 Day 93, Bonus 2)
I was amused by how much the PDP-11 console's color scheme reminded me of the UI from Stark Trek: The Next Generation. :P (From the Computer History Museum.)
The Museum and its hardware. Still work in progress, a nice improvement compared to a few weeks ago, thanks to a lot of hackerspace dwellers who helped out. An awesome upgrade comparing to when we first moved in and the previous hackerspace location.
A Casio pocket computer (with the BASIC language) and its Soviet clone.
The Elektronika MK-85 was designed to have a look and a human interface near exactly the same as the FX-700P.
However, the FX-700P is a calculator but the MK-85 is a PDP-11 compatible computer (not a PDP-11 clone as the chip design was an original Soviet work).
This, of course, means that the Soviet one is heavier and it used more energy. It is also slower in the basic mode (I don't have tried the "turbo" mode as there is no power adapter available). Anyway the Soviet model has graphical functions and Russiian alphabet output that the original machine don't have.
The first sign of a bad C439 is a vertical stripe on the left side of the screen. More info: trmm.net/VT100
Die Ansteuerung der LEDs macht übrigens ein kleiner Linux-Rechner (single board), Details dazu hier: retrocmp.com/projects/blinkenbone
The Museum and its hardware. Still work in progress but an awesome upgrade comparing to when we first moved in and the previous hackerspace location.

Cheshire's PDP-11. The cabinet claims it's a PDP-11/03, but it has been long since upgraded with a CPU from a PDP-11/73. I believe it has 4 MB of RAM (which would be the limit due to the 22 bit address bus on the QBUS and the J-11 CPU chip set), but the architecture limits the address space of any single process to only 64 KB. My first introduction to an MMU was to divide a large physical address into many small logical addresses. These days, MMUs are usually used the other way around.
It was originally put into service in 1983 and is still operational. It runs the TSX-11 timesharing system over an RT-11 kernel.
Also on the QBUS are a pair of third party co-processor boards, each with 4MB of linear addressed DRAM, one with an intel 80486 (the XP-11) and the other with a Motorola 88000 (sometimes known as the YP-11). We used a Greenhills C compiler hosted on the co-processor to build utilities that needed larger address spaces as well as more raw CPU power.
Also in the rack are 5.5" and 8" floppy drives, the hard drive, and a 9 track tape drive. The whole thing would fit in one 4foot tall rack, but we got a good deal on two...
The minitower sharing the hollow at the right is a Pentium 2 PC running Win2K.
The lower right corner is missing because this photo has been substantially corrected for perspective in Photoshop and the pixels just weren't present in the original image. The alternative would have been to change lenses to something wider so that I could have put the camera directly in front of the rack, but it isn't in a very large room and the wide angle lens I have available is a lot slower than the 50 I used for this shot.

Soviet monsters... Both are portable, by the way. The MK-92 docking station can work on batteries, too.
Trying to input the Moscow Nights melody (en.wikipedia.org/wiki/Moscow_Nights) into the Elektronika MK-90 computer (PDP-11 compatlble portable machine with a clone of DEC BASIC interpreter..., ru.wikipedia.org/wiki/%D0%AD%D0%BB%D0%B5%D0%BA%D1%82%D1%8...).
The program was included as an example in the original manual (the right page on the picture).

Documation was the OEM that produced this card reader in 1978. DEC re-badged the machine and sold it as the CR-11.
