Intriguing. I guess that bit is in one of the non-volatile FPGAs?
I've been puzzling over the FPGA booting process for my own project.
I have a hard 65C02 and Flash ROM already, so I could them to config the
FPGA, but then I'd need some RAM and a small CPLD for minimal memory / io
decoding.
In the end I think I may just use a small AVR to do the job.

I presume the Daniel Wallner T65 is just a part of the CPC project.

Agreed. MikeJ is working on a 68K design, but I suspect that will take up a
lot of FPGA logic. AFAIK, you can still get 68K CPUs fairly easily and
cheaply. I saw them for about �7 each in packs of 18.

It can't be that bad if people are buying it.

Hmm. I don't remember that as a popular or brilliant machine.
