I think it looks pretty cute tucked in there at the back of the #ZX81! And way less bulky than the original 16k packs, so less chance of it working loose.

Also, check out the RAMTOP! soooo many Bytes! #RetroComputing

Photo montage showing a ZX81 with home soldered 16K expansion board tucked into the rear expansion slot. Shown from both the front and rear view. Also a photo of the number 32768 on the screen corresponding to the RAMTOP i.e. the maximum RAM address used by BASIC. This is in contrast to around 17000 that is displayed with only 1k RAM included with the base unit.

Considering how bad at soldering I am, that didn't go too badly. I possibly have 16k, but don't have time to test it just now #ZX81 #RetroComputing

Photomontage showing 2 pictures, back and front, of a home assembled 16k memory module for Sinclair ZX81. One side has two chip holders with IC's inserted, and the other has the edge connector soldered on place. Soldering looks a bit patchy, but they all seem to be passable connections... Honestly.

81Zombies is now officially a thing! It's possibly the best turn-based-desk-building game that's been released for ZX81 all day, so feel free to check it out! https://hundstrasse.itch.io/81zombies

New on the blog: There was going to be a footnote, last week about how while I was using a combined m68k/z80 assembler for my Genesis projects, my dedicated Z80 projects would be shifted over to a simpler (and incidentally more ZX81-friendly) toolchain.

This turned into doing a modernization pass on some of my old implementations of the Lights-Out puzzle, which in turn also lets me play around with questions of data representation.

Pretty close to getting to a complete version of my #ZX81 game... Imaginatively titled "81ZOMBIES"... Just added in code to generate the 5th room type, but it's back to trimming as currently runs out of memory assigning the first loop variable.

After that I actually need to play it and possibly tweak numbers etc.

I really wanted to add silly randomised names for each room, but currently can't spare the bytes. If I somehow find a couple of hundred then I might think about it. #RetroComputing

Like all the best survival horror games, you can find a warm safe room to change your loadout and check out any items you've picked up... Or in this case re-organise your deck. #ZX81 #RetroComputing

okay, I don't know the specs of #ZX81, I don't know how its #BASIC compares to basics I know, I have no idea what #Minstrel 4th is, but yet the post by @tynemouthSoftware feels appealing to me ... → #booxread

The conclusion to the French game Nightmare House, featuring buttons you're not supposed to press and levers you aren't supposed to push unless you want to die.

I go more into the circumstances the tape was preserved and the early French adventure game industry.

Next on All the Adventures, a mysterious ZX81 French adventure crammed in on a tape full of other programs with no author and no date.

Also, a flask of acid gives leprosy.

NEU bei VSG: Diese Geschichte habe ich nach einer guten Flasche Rotwein im Jahre 2003 niedergeschrieben. Vielleicht war es das Retrofeeling welches mich dazu bewegte, oder halt nur die Angst diese schöne Zeit aus dem Gedächtnis zu verlieren. Viel Spaß beim Lesen…

Die Reise zu den Space Invaders – Teil 1: Von PONG zum ZX81

Dies ist meine Geschichte wie ich zum Computer kam. Es muss schon sehr lange her sein, als ich mich für elektronische Spielereien interessierte, ich sag mal so gegen 1972.
