Retro coder and homebrew computer maker, fan of all things 6502, electronics and retro computers in general. Z80 vs 6502? I don't care they're both in computers I loved back in the day. Oric, Atari and Amiga were my childhood machines!

Trying to smooth scroll on the TMS9918a is a little tricky - need to pre-scroll all graphic elements based on where they are in the tile map. Anyway kinda got it working - now to do something with it! What do folks think could suit this kind of feature? #retrocomputing youtu.be/FrumT_-Iq7s

TV showing a pic of my Birmingham uni flat from 1990. In that mess is my Oric-1, and in real life there's my same machine still going strong in 2026! Love my first home computer, been through thick and thin with me!🤗 🤓 #Oric #80s

I'll be at retrofest 2026 in Swindon with a bunch of people passionate about digital preservation of early micros. My Oric computers will be there as well as my Heath-Robinson homebrew computer, an homage to the pioneers🤘🏽 Book your tickets now as last year was sold out! youtu.be/oKRC85vtLmk

Can my homebrew computer on breadboard control a real-world device? Yes it can!😎 This is 1980s style computing with some basic transistor interfacing to allow a pin on the homebrew's AY-3-8910 chip to control a fan!🤓 #iot #homebrewcomputing #6502cpu youtu.be/GFZZXpsBTvM

6502nerd @6502nerd.bsky.social · 31/01/2026

Tweaked the game a bit - improved the backdrop graphics with a proper Death Star that come up over the horizon! This will go up on GitHub soon. I think it looks a lot better and quicker to draw than the method of drawing circles to make a Death Star! #8bitcoders #mos6502 #oric #retrocomputers

6502nerd @6502nerd.bsky.social · 31/01/2026

Port of a game from dflat to native Oric - easier for folks to try using emulator or even real machine. I've made some improvements too e.g. the game music which is a decent rendition (not by me!) of a legendary electronic track. #programming #8bitcoders youtu.be/jMgaQnY0t24

Woah, my uni mate Stu (met him in 1989) came round this weekend with photos from back in the day. Thought I would share this one (late 1990 / early 1991) of him playing on my A500 (with A590 HDD). Looks my version of Tetris which I wrote in C. #amiga #a500 #tetris

6502nerd @6502nerd.bsky.social · 30/09/2025

Interesting to see different C compilers for the Oric🤓

6502nerd @6502nerd.bsky.social · 28/09/2025

Programming in C for the Oric is possible thanks to OSDK! Here I ported a program from dflat (see elsewhere about this) to C. Despite my handle, I do like C - learnt it back in early 1989 on my Amiga A500. As we know, C is still used extensively today! youtu.be/wLsLQ_LsYGU

I've modded my homebrew - too many peripherals makes it unstable I think. So no more real time clock, but kept the 6551 ACAI for serial. This video shows a custom file transfer protocol to get files from the PC onto the homebrew! youtu.be/ms-w9NC0ubs

Day 92 - #retrorandom - Seeing this beast is always a highlight of any retro festival (this was from Cambridge in 2024). It belongs to @6502nerd.bsky.social and although it might look like an explosion in a breadboard factory, it's actually a working (and rather powerful) 6502 based system ... 1/2

A quick Oric and dflat update - my Tetris in dflat is now running PT3 mod files in the background. The game is very slightly slower with background music but I think the overall experience is improved due to the audio. Some nerdy memory dumps also shown🤓 youtu.be/w9TSx_pyq_I
