Minimalist Europe Card Bus (MECB) – MC6809 CPU Card (Part 2 – Testing)
This post follows-on from my previous post, where I presented and assembled my first prototype PCB for a 6809 CPU card, for the MECB bus. The first part concluded following …
Minimalist Europe Card Bus (MECB ) – MC6809 (or HD6309) CPU Card
This post follows on from my earlier Minimalist Europe Card Bus posts and videos. For MECB, to date I’ve designed and built a Backplane, a Prototype card, and a TMS9929A …
Minimalist Europe Card Bus (MECB) – TMS9929A / TMS9928A VDP RGBS Video Card
Earlier, I posted an article and video on my TMS9929A Video Display Processor (VDP) rediscovery. This included designing an alternative Retro VRAM solution, which I then implemented as a breadboard …
More AliExpress Re-Marked Chips – Follow Up! (6809 / 6309 CPUs)
This is a quick Follow-Up to my recent post and video on my AliExpress Re-Marked Chips Frustration! You can find this here: More AliExpress Re-marked Chips Frustration Since then, I …
More AliExpress Re-marked Chips Frustration
Join me as I describe my frustration with AliExpress sourced, incorrectly re-marked / re-labelled, IC parts. This seems to be an ongoing issue, particularly with the retro chips keenly sourced …
Minimalist Europe Card Bus (MECB) – Address Decode / Glue Logic ATF16V8
As I mentioned in my earlier MECB posts, I wanted to be able to create MECB boards which implemented addressing flexibility. This is to allow any I/O board design to …
Minimalist Europe Card Bus (MECB) – Prototype Card Design
This follows on from my Backplane Design & Build for the Minimalist Europe Card Bus (MECB), where I walked-through the design of my MECB Backplane, and I then assembled my …
Minimalist Europe Card Bus (MECB) – Backplane Design
This follows on from my Introduction of the Minimalist Europe Card Bus (MECB), where I outlined my preferred design, for recreating some of my 8-bit CPU experiences from the late …
TMS9929A VDP Rediscovery and Alternative Retro VRAM Solution
TL;DR The TMS9929A / TMS9928A / TMMS9918A are Video Display Processors produced by Texas Instruments in the Retro 8-bit era of the early 1980’s. They were used in a number …
Minimalist Europe Card Bus (MECB) – Background & Introduction
TL;DR Europe Card Bus (ECB) is a Retro CPU Bus standard from the late 1970’s / early 1980’s. The “Minimalist Europe Card Bus” (as I call it), is a Retro …
