Having done as much as I can for the moment in Digital, it's time to switch over to validating in circuity. I bought an EPROM programmer and UV eraser online for the M27C1024, a 256x16 bit EPROM that this is now obsolete, but which has the rare property of having a 16-bit wide data bus. Getting one of these EPROMs will probably take another week or two.
