The postman bought me a package today containing the updated versions of most of the PCBs from the website as well as the new ones for the MiSTer -> Gorf (and others) interface.
I need to get soldering and make sure that they actually work. I think I’ll start with the multigame, not had one of those for myself for ages.
One of the PCBs I own had a dead SLAPSTIC, Atari’s custom protection chip used in several games of the time, which meant I just got a nice ROM error in test mode and a blank screen instead of the game. Some old 8 bit hacking and we have hopefully fixed the problem. Check out…
The Retro Chip Tester (RCT) was developed to test „old“ memory chips from the 1970s and 1980s, which are often no longer recognized by today’s programming devices. The RCT is able to identify defective memory cells very reliably. It can save the contents of ROMs, PROMs and EPROMs to a memory card. If the memory…

I have a few customers who buy several sets of PCBs to allow them to sell kits or fully assembled versions of my projects. It only seems fair that I reward them for their continued support, so in future buying 10 sets of PCBs will enable a 10% discount. If you really want to go…
One of the reasons I wanted to build a Retro Chip Tester (RCT) was because there are several adapters available that let you extend the capability of it. The one I had an immediate use for was the 2708 programming adapter. I ordered some PCBs for this, put it together and it has now been…
It seems that some of the multitude of changes in policy within the USA have meant that the British postal service will no longer accept packages destined for that part of the world. So, until this situation has been resolved, I can no longer send anything from the shop to the United States of America!
