RC2014 Mini on MAME
TL;DR Getting an RC2014 Mini working based on the Grant Searle Simple Z-80 Machine driver was pretty trivial, but it’s been enough to get me going with MAME development and persuade me to try some other things. Background I know there are already emulators out there already for the RC2014, I’ve used EtchedPixels/RC2014 a bit […]

TL;DR I’ve been wanting to try emulating some RC2014 stuff using MAME for some time, and I think I’ve found my way into it with the MAME driver for Grant Searle’s Simple Z-80 Machine. Background Back when I was making my TMS9995 on RC2014 system part of my adventure into the lands of TI-99/4A fans […]

It turned out that my TMS9995 system had no modules in common with my CP/M system, as it’s using the ROM and RAM modules left over from the CP/M upgrade. All I needed was another backplane to be able to run both at once. SC116 3 slot backplane As the TMS9995 uses three modules: CPU, […]

Having got a TMS9995 system on RC2014 working as far as the monitor I still wanted to run BASIC and Forth. I’d not been able to get my pageable ROM card working, and the switchable ROM module is too small. But it’s too small because it’s designed to carve a 64K EPROM into 8K pieces. […]

I already wrote about my plans to get a TMS9995 running on RC2014, so this is the post about how I put together an RC2014 version of Stuart Conner’s TMS 9995 Breadboard or PCB System. Planning Taking a look at the TMS9995 pinout and the RC2014 module template it became clear that there was no […]

After building my RC2014 CP/M system and Gigatron I decided to dig through the pile of old integrated circuits I stashed away before leaving home thirty years ago. I don’t remember the source, but it seems that I stripped down 4 systems (which might have been something like data loggers) that had a reasonably complete […]

Retro Computing – RC2014
This is the first post in a short series (with perhaps more to follow as I go deeper). Why? I came across the RC2104 at OSHCamp 2018 where I got to meet its creator Spencer Owen and make one of his Mini kits with my son. When he put his Full Monty kit on sale […]
