Re: 3D printing assistance

Re: BeebSCSI 7_7

All very odd, but that makes 3 different reports of BeebSCSI not being 100% happy with the Master 512. I wonder what it all means. I had problems with a Master 512 and a BeebSCSI mini if that counts. Worked perfectly for normal ADFS use. I could create a 'C' drive (having booted DOS plus from flopp...

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...
