I’ve been looking for a laptop for a project I have in mind (spec not too important, or possibly even a working display).

Re: Acorn AKA31 SCSI podule / A310 incompatibilty?

Not all A300 backplanes were equal. BITD I started off with a Watford 4-slot one which worked fine with the Acorn ST506 card but couldn’t cope with a Morley cached SCSI card. I ended up having to change to an IFEL 4-slot. Which worked fine with an Acorn SCSI card for many years. You’d have thought a...

Re: LOLPRICE

It’s a very rare A400 - the rear only has composite video out, not high-res mono. That’s why it’s worth £700, especially if it’s that ultra-rare variant that also didn’t have on-board ST506 controller.

Oh, wait...

Re: I've been made redundant

You are, of course, assuming that they interviewed the people who scored even higher.
If there’s actually an upper limit which people must score below to be employed, it would explain slightly more about the state of the country.

Re: Chess Wars - Battle of the 8 Bit Micros

Contemporary reviews would suggest that Acornsoft chess was one of the weaker BBC chess programs.
White Knight (latest was Mk12 afaik) and Colossus were reviewed more favourably.

Couldn’t personally verify this as my chess was considerably weaker than any of them!

Re: Real HD images in B-Em

Or you could run the file through: and then it would be suitable for use as a SCSI image and can be used with unpatched ADFS. If it is useful I could look to make the SCSI disc driver handle the IDE format files. My original intention was compatibility with BeebSCSI but it sounds like it would be u...

Re: Ample Rom query

108801 in Base 9 converts to &FFFA, so it just works as a 16-bit romid. Presumably, for any given release of issue disc, all the modules on the disc are pre-coded to give the same checksum, so the same passcode will mod all modules in that software release version to the same romid. It may be re...

Re: Ample Rom query

That’d be my guess, although I can’t comment on your checksum generator. The only benefit from working out how to back-engineer the passcode from the offset would be the convenience of just putting it into the Issue disc and getting it to make all the correct modules, instead of having to create the...
