This was working about 3 years ago. No PSU! Just P&P . . .

I’ve been looking for a laptop for a project I have in mind (spec not too important, or possibly even a working display).
Happy to throw in a small donation to Centre for Computing History.

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...

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...

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.

Can I reserve one of each please?

PM sent.

That first picture isn’t even of the machine itself - cursor key arrows are wrong.
Odd how there are loads of pictures of the packaging but none of the whole machine - always got strategically placed manuals....

Hopefully that also holds true for systems that have had a clean install activated with the Windows 7 key too if I ever need to re-install this one :) Has done for every (re-)install I’ve done up to this summer, which is a lot. All of them done originally with Win7 keys, or pre-installed oem 7. The...

Glad to hear you got it Tim! :) Do you have any greater insight now into what Bill Gates is planning to do with his army of octogenarians? :wink: :) Nope, but I've suddenly developed this irrational hatred of Linux. And it would explain why we were all having memory problems in Handover this mornin...

A certain jab in the arm. At least the vaccine is one way covid can be compared with flu - the side effects seem to be milder than the flu jab I had last month. And I don’t seem to have gained/lost any body parts. Which is probably all just as well, considering that if there ever were going to be se...

I’ll take it, if it’s still available.

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!

Interested in the matchbox if still available.

What happens using ADFS instead of the Midwich DFS?

CEX do

345FE799-745A-4974-B139-3523A63C67A9.jpeg Even the fuse holder is Acorn green! When were these actually sold? I can’t find a mention in any price lists, dealer ads in magazines, or any reviews. The only mention I’ve ever found was in “The Acorn Guide to the Micro” magazine supplement. Edit: Dec ‘82...

It now works! Renaming the existing .dat file to scsi* worked fine, once I'd worked out where I then needed to put it. For some bizarre reason, it wants the scsi*.dat files in \User\*\AppData\Roaming\b-em.exe\scsi, but then creates scsi* files (no extension, should it be .dsc?) in the main B-Em\scsi...

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...

I *think* that's what I've been doing. I renamed ADFS0.dat to hd4.hdf, tried locating it in B-Em's folder and/or ~\AppData\Roaming\b-em.exe folder. Tried running B-Em with IDE HD selected and ADFS 1.53 loaded (or 1.50, just in case). Still no joy, whereas BeebEm with IDE HD selected and ADFS 1.53 ju...

I have a pair of images of my CF card disc partitions - ADFS0.dat & ADFS1.dat. These read fine in ADFS Explorer, and BeebEm. In B-Em, it's a different story. Best I can get is "Broken Directory" when trying to *MOUNT them. And I'm not too sure it's really reading them, even then. How d...

If you can find out what CPC’s latest special offer code is (two more digits to go on the end of the order code, so it’s 7 characters rather than 5), it’s always worthwhile trying them on the end of anything you order from CPC - quite often what you want is also on offer but they don’t tell you on t...

I’ve got the same model. Extremely useful and usable, even in my ham-fists.

Don’t mention The Scottish Drive!!!

‘Tis terrible bad luck. A curse on all your data!

Boydie, Not your fault in the case of B-Em. Some random junk (keybaord malfunction) had crept into Makefile.win. I have pushed a change to fix that. I am not sure I have ever compiled Allegro on Windows. I have downloaded release packages from the Allegro GitHub and, when I needed to patch it, cros...

This is turning into quite a voyage of discovery! I'm trying to compile the lastest version of b-em-master from github, on Win10. I've downloaded and installed MinGW (all the Basic Setup), and downloaded and compiled allegro-5.2.2.0. All of which was considerably above my usual skillset, but I think...

But they don’t count (at least not any more)?

I've got an unused Z80B (part no Z8400BB1) from 1990 or thereabouts, if that's any use.

Alternatively, I can always just upload my M5000 and M5000-4 Issue discs, with passcode and rom id (and rom image) when I get time!

Then effort can be focussed on other discs in the series.

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...

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...
