Yup ... just one (32k) ROM to dump though (2 copies of the same thing) ... brought it with me today to the ABug meetup for dumping ... I think you'll be interested in the contents ... ;)

hmm, it's interesting that it's provided for the master, was it master-only? (then perhaps 65c02 opcodes were used, I've not checked the other ch200/chadfs rom dumps for this yet)

No idea if it's Master only.

Here's the ROM dump.

Does it look any different from the existing dump?

I did a bdiff and it's exactly the same as rom 527 (which is the same as roms 525+526), so, this needs looking into as there are now multiple rom images that are the same and it's inconceivable that if any bits unprogrammed (as happens slowly with eproms over time) that that would happen in the same way in each eprom.

So perhaps it's master-only. I will have a look soon if there are 65c02 opcodes.
