Sad old fart that I am I do have a fondness for old computer games. In this case we have one of the later Ultimate Spectrum titles. A little past the greatness of Sabre Wulf and Knight Lore.
I've been getting some home-made ZX Spectrum programs off cassettes that have been various lofts for decades. Amazingly, most still load. See github.com/blogmywiki/ZXSpectrum for files you can load in emulators.
The Z80 CPU from a ZX Spectrum 48K, I was probing the clock input I think. Little known fact, Z80 CPUs can be paused!
TECHNICAL ALERT!
This is where the magic happens, well actually that happens in the ULA. This is where all the code happens, when the ULA lets it.
That ULA is one bossy cow.
NON-TECHNICAL VERSION:
Stuff happens that you don't understand or care about.
Busy sorting through old stuff. Haven't found by ZX Spectrum yet, but I have found a grubby WH Smith's "COMPUTER PROGRAM DATA RECORDER" and it still works :-D
“I think they are atrociously amateurish. They are marvellous at making programmes and so on, but by God they should not be making computers, any more than they should be making BBC cars or BBC toothpaste”

This is a little notebook I kept whilst I was developing stuff (i.e. playing) with my Jupiter Ace computer in the early 80's. The Jupiter Ace was a Z80 based computer from two guys that used to work for Sinclair on the ZX81 and ZXSpectrum. Its unique features were: a very cheap plastic case made out of the same plastic as yoghurt pots, a small amount of memory, a terrible rubber keyboard, and instead of BASIC, a language called FORTH.
Learning FORTH was a huge thing for me - it definitely did me the world of good, and predated languages such as C or Java in terms of breaking free of GOTO loops.
I developed a lot of software for the Ace, including some games which at the time I considered damn good. I suspect they have been lost to history. They were ALMOST about to be sold commercially when the Ace pretty much sank.
This cute little keyboard was intented for use with Sinclair ZX Spectrum as well as ZX81. Despite semi-pro appearance, the keyboard is still very clumsy compared to modern keyboards. Keycaps are removable and there's a Sinclair Edge Connector at the end of the flat cable.
Dvoj-tlačidlová Genius Mouse v originálnom balení.
- Konektor:9 pin M (samec)
- Rozlíšenie: 200 DPI
- Protokol: <a target="_blank"class="valuelink" href="https://en.wikipedia.org/wiki/Bus_mouse
-">BUSmouse Typ: GM7
*Upozor-nenie: Pre pripojenie do PC potrebuje ISAkontrolér pre BUS mouse protokol*
Vzhľ-adom na jednoduchý BUS protokol jeveľmi vhodná na pripojenie k domácim počítačom ako napríklad:
-Amiga
- Atari ST
- Amstrad PCW
- Commodore 64/128
- Sinclair QL, ZXspectrum – datel – link – <atarget="_blank" class="valuelink"href="http://k1.spdns.de/Vintage/Sinclair/82/Peripherals/Mouse%20Interfaces/Datel%20GM-7%20Bus%20Mouse/

- Apple
V niektorých prípadoch postačí zmena zapojenia pinov(redukcia),
niekde postačí pridať pár súčiastok, v iných prípadochje potrebný interface.
A-miga – Bus Mouse redukcia (prevzatéz internetu):
- amiga pin.1 = mouse pin.4 (V pulzy)
- amiga pin.2 = mousepin.1 (H pulzy)
- amiga pin.3 = mouse pin.3 (V smer)
- amiga pin.4 = mousepin.2 (H smer)
- amiga pin.5 = mouse pin.5 (M button)
- amiga pin.6 = mousepin.6 (L button)
- amiga pin.7 = mouse pin.7 (+5V)
- amiga pin.8 = mouse pin.8(GND)
- amiga pin.9 = mouse pin.9 (R button)
Daily App Experiment #90: "Zed X'd" - portrait of @crashfaster that I ran through ZXCam, an app that replicates the image compression technique used in old ZX Spectrum computers. The effects were cool, but I wish the final exported image was higher res. These types of image look great with crisp edges. For the IG version I added the Earlybird filter. #daily_appsperiment #appsperiment #ZXCam
Damn, not again !!
It happens to me a lot ~_^
...by the way, my screen flickr name is "Manuel_ZX48k" because
I have only 48kilobytes of memory in a world where the standard is 1 Gigabyte
yes, i'm that forguetful - at least i'm kinda smart :D
=photo is from a zx spectrum game called "Dan Dare", this is the default hiscore screen=
#REPOST#
ZX Spectrum 48k (my second ever computer, from 1983) loading Manic Miner (..just) via my iRiver MP3 player.
I can't tell you how fun it was to play a couple of caverns on the rubber keys :)
