One of the users discovered a minor problem with the Fluke pod converter PCB which causes problems mainly when used on Zaccaria pinball PCBs.
It seems I missed one of the tracks off from the original article that connects the INTACK signal to GND.
This has been fixed on the latest PCBs, but if you have this problem see the main page for info on where to add a link to fix it.
One of the members of UKVAC (Aaron) put together a piece of test gear that allows you to visually check the signals on an IC whilst the board is running normally and I picked one up earlier this year as it can do a few things that the ABI Board master cannot. Having sourced a…
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…
I fondly remember playing games like Confidential Mission on my Dreamcast in the games room, displayed on a 26″ Hantarex screen that came out of a video conference room. However, with the switch of TVs and monitors to LCD / OLED etc, these old guns no longer work. After doing some browsing across several web…
I have finished moving the remaining pages from the old Frontpage website over to WordPress and put some of the archive history back in. I did have to modify a few things to make it more ‘mobile’ friendly so all pages should be viewable on your phone. (a few require you to rotate your phone…
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…
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…
