When you have a board sorted even if there's no FPGA code working on it yet, let me know. I'm quite interested in doing a port myself too as a fun project.
Will do . . .

Re: EUPURS and AP5 Cable(s)

As a matter of interest Do the cables you supply connect to user port 2 Idc or the pin header? I'm supplying the USB to Serial leads, the one recommended by MartinB, along with a 9 pin 'D' to 7 pin connector for the header pins - I epoxy a 4 and 3 way together and 'mark' pin 1.

Is there any slogger plus 2 bareboards still hanging about, and would they work with an AP5. I would imagine a 'cut' down version of that that only had the extra cartiridges slot would be useful.

Although I still had an unanswered question about the MRB assupmtion. i.e. If you have one do you unplug that and put the 6502 back in? And it doesn't explicitly say (or I dont think it did) but the spec seems for the 'Ultimate ULA' seem to improve upon the standard MRB anyway. Yes, you'd need to r...

One of the big problems, for some potential users, is the removal of the ULA socket without damaging any of the tracks. I had planned to build a good sized batch of maybe 50 and offer a fitting service for those that can't. I'd be very wary of anyone having-a-go and then blaming the problem on the p...

Re: Missing old/new Electron Expansions

An Electron ULA replacement is certainly technically possible, but I think the cost would work out at ~£50-£60 which make it unattractive, given working Electrons can be had for about half this. So it's been stalled for over a year now. My 'tardiness' can't have helped either :oops: Re the cost: Is...
