Continuing on, with my Minimalist Europe Card Bus project. Join me as I introduce a 1MB ROM Expansion Card, discuss the design decisions, and assemble my first card. First some …
It has been pointed out to me, that I had overlooked officially documenting the MECB Bus pinout. So, itβs time this oversight was fixed! I suspect that, originally, I was …
Although this post is not in-line with my normal Maker / Electronics / Retro Computing blog topics, it is related to the flooding which destroyed my Workspace approximately 12 months …
In the early computing days of the late 1970’s, back when we were building our own 8-bit microprocessor systems, it may be hard to imagine now, but we didn’t actually …
After some on-going frustration with the WordPress blog comment limitations, I finally decided it was time to setup a proper Forum, to allow more advanced (and more readable) discussion going …
I just received some old MOS 6502 microprocessor chips from AliExpress, for a project that I’m currently working on. Now, I needed a way to test that the received chips …
As I now have a modular retro 6809 computer system, with a flexible memory map, I thought it would be fun to mimic another simple 6809 system and to also …
After my long journey making my final Ultimate Cherry MX Version of my Hex Keypad, and in fact being very happy with the results I’d achieved, I was still contemplating …
Following my recent 6809 system testing video, a viewer asked if the system could run at 3Mhz, or perhaps even a little higher. Join me as I initially test the …
