This sounds like absolutely great progress! My intended application is with DEC MicroVAXen so that should be a bit different to the systems mentioned so far.
I have two hurdles to cross before I can get a working board.
The first is the 1.8432MHz oscillator. I have had a devil of a time sourcing this part. In the end I had to pay through the nose for Digikey to ship them from the US and answer all sorts of export control questions. Appeal to Andrew on this: where possible please design future boards with parts that are more commonly available, in particular this part seems to be more readily available in a large DIP14 package rather than DIP8.
The second is the EPROM Programmer. I was given something not so long ago which I hope will work, but I need to put together a machine with a parallel port first. I have seen some discussion about this over the last couple of days, and it seems to be a bit of a problem, a cheap USB solution that works on 64-bit Windows would be great if anyone knows of one.
Regards
Rob
