Disc Doctor - Computer Concepts

Nothing special but I just noticed that my original Disc Doctor is a different version to those available elsewhere. Looking around there's 1.09 and 1.0B, now we have 1.0A to fill the gap!

Re: MAME: Speech

Darn it! Yes, it should have said bit 7 is READY, bit 6 is INT. The stuff about the connections being swapped over on early issue boards still applies. I've been working with the Cheetah Sweet Talker recently which puts its ready signal (SBY) on bit 6 adding to the confusion. ](*,) Ok, glad to have...

Re: MAME: Speech

With the original beebem, only the OS speech works, but my current one supports all three. I can put my current version up tonight if you like. I thought I had your version from 2015, but what I have doesn't detect OS speech. The speech presence flag at &27B is not set. Bit 7 is INT, bit 6 is READY...

Re: MAME: Speech

Implementing the Acorn Speech is still proving a challenge. In OS1.20 it is checking bit 7 of SYSVIA PB to determine whether Speech is present, whether this is the ¬READY or ¬INT output from the TMS5220 is still up for debate. See OS code at http://mdfs.net/Docs/Comp/BBC/OS1-20/D940, speech check at...

Re: MAME: Sideways RAM/ROM boards

MAME: Sideways RAM/ROM boards

MAME apparently supports Acorn 64K/128K sideways RAM boards in a Model B. I'm thinking these are fake and never existed, can anyone prove otherwise?

Time to add the more common ATPL, Aries, Watford, Solidisk boards, and remove Acorn if not proven to exist.
