Resurrecting this thread since I've just found out about this machine in the past fortnight and this is pretty much the only place that discussed the machine. I've recently added support to z88dk for generating Supervision 8000 ROMs and am currently testing in Mame. However, it's always good to get confirmation that it actually works on the real hardware - does anyone own the real hardware and can create cartridges? If so, I'd really appreciate some validation. I can provide a ROM image of the DStar port shown below (it's fully functional with 25 levels) Secondly, Mame limits the cartridge slot to 4k (I guess because all the available software is that size) - is it possible to load larger cartridges on the real hardware or are all the address lines not routed?

So, I was looking around for another target to support within z88dk and I ran into this thread, the relative obscurity of the machine makes it an interesting target to support and I thought it was going to be easier than the FP-1100. I think I have something that can create ROM cartridges, however I can't seem to get the cartridges to load in Mame - looking at the debugger I can't see the image ever being paged in during the cartridge signature check. This probably means that either a) I've done something wrong, b) The support for the cartridge slot isn't complete in Mame. Can anyone confirm that cartridges are loaded correctly/share a link to a working cartridge so I can see what I've done wrong? Thanks. BTW, the basck tool within z88dk is very useful for discovering addresses in ROMs - it analyses Microsoft and Hudson BASIC ROMs and determines addresses for the commands, floating point routines etc
