More Info:
As the Baffa-2+ looks like an end product, why not invest in advertising?
As seen on tv :D...
The Single Board Computer is equivalent to the following set of Baffa-2 boards:
- Baffa-2 Full Backplane
- Z80 CPU
- Dual Clock
- Dual Serial SIO
- Soundcard Ay-3-8910
- 8255 IDE
- 512KB RAM/ROM
- Real-Time Clock
- Minimal Terminal or PI Pico Terminal
It used a Z180 CPU that provides integrated serial, pio and ctc, so it groups some peripherals on a single board. Similar Baffa-2 setup using Z180:
- Baffa-2 Full Backplane
- Z180 CPU
- Soundcard Ay-3-8910
- 512KB RAM/ROM
- Real-Time Clock
- Minimal Terminal or PI Pico Terminal

Wow! What a throwback that enclosure is! But very nice project and awesome build. 512kB of RAM and ROM would have seemed impossible back in those days but I think it's great that today we can both pay our respects to those old designs and make use of some modern tech to improve them. Sort of a "what if". Do you have any period software running on the Z80?
