Re: Developing using the 9100

Have a look at a 2nd hand Dataman S3 (or an S4, these are a more
expensive update). I used these as an EPROM programmer/emulator for
several years in the 90's, for 27C256's and the like. It might not be
able to do a 2716, but might be able to do so easily with a correctly
constructed adapter.

I'm not 100% clear from the description on the site of what size eproms it emulates either. I'd want it to emulate a 2716. And I also don't have a parallel port. Maybe there's something similar that doesn't cost so much though?

I've got to the point where I want to debug it on the real hardware so obviously the first thing I wanted to do was try and avoid keep burning ROMs all the time. The code is only really a proof of concept so it's very small. I've relocated my code down to zero page and I can transfer it to the PCB's memory that sits from 0 - 3FF.

It's a bit of messing about but I can basically assemble the code, convert it to Intel Hex format, transfer it over serial link and then write it to the PCB's memory and execute it. The only caveat is that I needed to burn a dummy ROM that sits at 7800-7FFF which solely contains the interrupt and reset vectors. So far so good.

The manuals for the 9100 very fleetingly mention something called POD overlay RAM which sounds very promising but I've not been able to find anything much more than just a quick mention.
