This is a cheap home brew SD card adapter for the Arduino. I will be using this with my Arduino Uno to make a SD floppy disk adapter for my 8bit Atari computers. See www.whizzosoftware.com/sio2arduino for more info on this project.

This has to be one of the best games on the BBC Computer!

One of my hobbies is collecting retro-computers, focusing on computers made by Atari. I have currently have eleven different Atari-models, three from Commodore and one other model in my collection.
The first computer I ever had was a Commodore VIC 20 that me and my brother got for Christmas in 1982. We got it with some books and some magazines, but no games and no cassette drive at first. So all we could do was type in the game examples from the books, try the game, and loose it all when we turned it off. On top of that it broke after about three days (some hardware error, not our fault), so we had to send it in for repairs. Probably took a month or so before we got it back.
Since we got no software with it, just the book with games and the magazines me and my brother took turn to type in the games that were listed. That way I learned both to type and the basics of BASIC. Didn't take very long before I made my own games for it. One was even so big that it filled up the entire 3K of available RAM....
Here are 4 of the 5 small board in my collection. I also have a Beagle Board, but its not in this photo as its in a special case at the moment.
More info about these devices here.
The Robotron KC 87, fully known as the Kleincomputer robotron KC 87 (KC standing for Kleincomputer, lit. "small computer"), was an 8-bit home computer released in 1987 and produced in former East Germany by the VEB Robotron-Meßelektronik "Otto Schön" Dresden, part of the Kombinat Robotron.
Issue 4 BBC Model B with a Aries-B20 20k RAM upgrade and Aries-B12 14 slot ROM board.
Also has a "Watford Electronics DDFS 1.50" DFS, Watford Electronics 1770 Disc Interface and a 40/80 track 5 1/4 FDD.
I've also disconnected the internal speaker, and connected the sound output to a phono port on the back using the hole intended for the reset button

I though I would take one of my old computers into work today.
This is what my desk looked like! Laptop is a Dell Latitude D820, and the Macintosh is a SE/30 running System 6.

So, you think the Apple iPad is a new thing...
The GRiDPad 1910 is the computer most commonly associated with the words "grid pad", AKA the brand name "GRiDPad", owned by GRiD.
The GRiDPad 1910 is basically an extremely portable PC-XT. It has a 640x400 backlit Monochrome CGA display. It has 2MB of system memory, and often came equipped with a 20 MB 2.5" IDE disk. The pen system is capacitance-based, with a wired stylus. There is a 6-pin micro-DIN XT keyboard interface. Audio is limited to the usual PC Speaker support. There is one serial port expressed on the unit, and expansion for a modem, which came in 2400 and 9600 bps flavors. There are two ATA-FLASH slots on the unit, which are used strictly for storage. There is also an expansion bus connector on the bottom of the system, which includes at least a keyboard connector, a parallel port, and a floppy bus. There are buttons F1 through F5 and a sleep button on the unit, as well as a hard power switch. Power is supplied via Ni-Cad battery packs.
This unit was used primarily for inventory purposes and the like. Apparently it was used within Chrysler for that purpose, and by the United States Army. The military specified more rigidity and durability from the case than the civilian version provided, and so GRiD made the case out of magnesium. They were never sold to the public that way, but occasionally a unit will slide out of the hands of the military.
I no longer own this machine, ive donated it to www.computinghistory.org.uk/

Original Steve Ciarcia's column on Byte Magazine:
With green phosphor monitor. My had 2x5.25 floopy some strange format of 480kb (if I remember it correctly). No hdd and bnc connector for lan. I am not sure what protocol just for copying files to server with 20mb hdd (cloud :) ). After first year holiday they were all replaced with generic PCs.
