Re: How did the Beeb use the /SO pin when selecting ROMs?

Hi, I forgot to say, it was a model A (mostly upgraded now) but originally came with OS 0.1 on the four eproms, so there were no slots free to install additional ROMs in any case.

Thanks for the various replies, particularly noting that the diodes went missing long before the service manual suggested. It seems their function is as mysterious as the /SO pin that they're connected to. I don't suppose any owners of an Issue 2 board would care to open 'er up and look to see if t...

I've had no problems using ISE 14.something with the parallel programmer - albeit for the GODIL rather than the matchbox co-pro.

Re: Matchbox co-processor new users

I think you need a much older version of the Xilinx tools - ISE 10.1 if I remember correctly - to support the Parallel Cable. But support for the Spartan-6 family (used by the Matchbox LX9) only came in with ISE 11.1. It's just possible, if you only want to use the programmer, that it would work, b...
