PCB is from the project for Amiga. A new PCB will be built for Atari, which will be more tailored.

I added support for Tos 2.06 (one wire connected to eprom / flash).

The project is under development. I plan to add MC68000 processor and overclock it.
Currently, I do not have a motherboard with a PLCC processor.

Ooh please tell me about your TOS upgrade here. I have a Mega ST that could desperately use this so my Marpet board will be useful.

My memory card decodes missing address space for TOS and generates missing signal.

Oh, excellent. Consider me interesting. Adding this to my Mega ST 2 with my Marpet Xtra RAM board would make it a really killer Mega.
