mike, yes I know that and that socket adapter part might even fit. But if I handmake board, I would use slim one row connectors in both side of the eprom to get it fit like its in my picture.
That's a very good idea. One thing that might help with wire routing is to use 2.0mm IDC cabling. It's a bummer that the 68K is on the rear of the board and my brain started to hurt when looking for a way to mount the Neobiosmasta and keep the stock case. I decided for my purposes the case would get in the way and that actually worked out very well.
Universe Bios for NGCD was successfully tested on the Top Loader, Front Loader, and CDZ. Neoturfmasta was instrumental in testing the core Universe Bios functionality on these platforms. What wasn't thoroughly tested was the PC2NEO functionality on anything other than the Top Loader. The reason for this was simply because I didn't have a CDZ until recently.
As soon as I modded my CDZ I ran some tests and discovered that hardware differences between the TL and CDZ were causing transfer problems on the stock bios. I immediately shared this info with Raz and he immediately made a CDZ fix. It turns out the transfer performance of the CDZ is actually better than the TL and I'm attributing that to the design of the CDZ joystick front-end. The CDZ does not use the NEO-BUF chips and it has a discreet implementation of the resistor/cap arrays found on the TL. Those seem to add a level of debounce to the lines which translates to a delay which is not present on the CDZ.
My next project is to populate all the blank DRAM pad landings with memory chips. Neoturfmasta had done this but I don't think at the time there was a good way of testing whether this memory was accessible. If it is then it will certainly allow for much larger MVS games to be developed or played.
Thanks,
Mike
