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!

Tetris converted from dflat to C using OSDK toolset - now that's much smoother!

A new video showing tools to allow Oric to play Protracker 3 files in the background from C language.
The Oric has a decent sound chip, I think it does a good job here, and now super easy to add high quality tracks to your games!

Interesting to see different C compilers for the Oric🤓

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!

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!

Ah, after ages thinking about it and feeling flush as I sold a few things on ebay, decided to scratch this nostalgic itch!
Feeling like 10 years old again thumbing through this amazing book🤗
Wish I had bought it when it sold for £2.95 back in the day!

Quick video of some copilot experiments to see if I can generate some 8 bit graphics for my Oric.. results are variable but not wholly unusable.
Good to know that even if software engineering is obsoleted by copilot, it might not replace my retro-programming fun!😆

Another 42 year vintage new old stock. Tape is being loading for the first time ever.
It worked sort of.. I had to fix a syntax error of a 1983 BASIC program I'd never seen before then try again!

I bought new old stock Oric software off ebay. So here we have a 42 year old set of tapes, loading through a 42 year old tape player, into my cherished Oric-1 which I've owned new since 1983.
For me the result is kinda mind blowing because it actually worked!

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

Looking forward to showing this mess of wires at the festival and very much hoping the kids keep their fingers away 😳😅

If you want to know more about it, don't ask me - ask Dolo himself! Please forgive the quick plug, but he'll be at the RetroFest in Swindon (retrofest.uk) and he'll be very happy to answer questions. My greatest fear is some young kid coming along and swapping some of the jumper wires ...

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🤓
