The SD-CF adaptor I bought a year or so ago didn't work with RISC PC :( Or A5000 - I ended up using it with Wizzo in the A5000 under IDEFS. Best option is to use an IDE podule. Next best is to see if you can get it playing ball with patching ADFS (as discussed above!): https://stardot.org.uk/forums/...

I was meaning to post a screenshot in this thread, but haven't managed to get around to doing it... If anyone's had the pleasure (and I mean it, it's hilarious) of watching Strange Hill High (CBBC), you'll spot BBC Micros in a few different places

I've had aviator running fine on a Master (and using the patched OS1.2 pretty much lets everything work) - that said, I didn't try using a release on original discs... Anyway, you can't play Prince of Persia on a model B or B+. And Exile is full screen on a Master without having to jigger about with...

Master. Every time.

well done!
Unless you've got the proper tools and want to save the IC, snipping the legs is the preferred method even for the experienced!

There was no official stand afaik - in fact most schools used to rest it on the beeb itself with a bit of wood or support behind it! Most metal plinths are like the one I showed a picture of and were made by third parties. There was a branded plinth for the master that had built in floppy drives, bu...

The cub overhangs every plinth I've seen...

I've unleashed a post on comp.sys.acorn.misc.... Goodness knows what the effect will be (I'm wearing stout undergarments).

Ditto - my DC seems to get leakage too.

d.

Although the ram does go, the 6522s are notoriously unreliable! Try swapping them over? That'll give you a bit of an indication...

d.

Battery is under the HDD and you can't see it - I'd not touch that personally!

d.

Hello! And welcome! :) Unfortunately you won't be able to use a USB floppy to get the game off that disc - they only read PC format floppies. You either need an old PC with a built in floppy drive, and the omniflop software, or else something like a kryoflux. Chances are that there's some copy prote...

Excellent - so, I'm fairly confident that my master's actually fine now, but I'm pleased this turned out to be quite interesting in a completely nerdy kinda fashion!

Do you see that hang even if adfs is the chosen filing system?

I'll try the other tests this evening!

d.

See what happens in different modes - as the master retains the current mode on soft break. As I said, 7 or 135 is fine, it just barfs in other modes (so I'm not necessarily thinking it's memory that's at fault here...) The only other thing I have in there is a NuLA which is on the same data bus as ...

Have you got an UPURS rom handy to pop in Daniel? (or even the disc-based utility versions?) If you repeatedly perform UPXROM ? you should get consistent SWR bank results each time. Just a thought if it helps.... :) I'll have a look at this tomorrow, thanks Martin :D I'm sure I've got it knocking a...

For completeness - OK, so it generally finds banks 4, 5 and 6, but it's sometimes finding 0, 1 and 3 instead of 7... Usually 1 if it's getting the wrong one...

d.

Well! There's a thing. Thanks Dave :) - extra brains are fab. It was fine with the FS's unplugged. I then realised that ANFS was in there and I'd obviously taken the econet module out whilst I was testing... ANFS was the guilty party on this one - once I'd re-inserted the filing system ROMs and plug...

good plan. One mo!

d.

Links are correct, it was behaving fine yesterday, just today it seems to have gone odd. I'm convinced this mode 7/135 being fine on soft reset, but if you're in another mode it hangs on soft reset before displaying the Filing System Banner (properly hung, caps lock does nowt) thing points at what's...

OK - I'll have a look and see what I've got in the tank to have a go at this. I think at this stage I'm just going to resort to rather a lot of clips or see if I can jerry-rig something with a 40pin IC socket...

I can MacOS on a laptop, I can probably reach from the pc with linux either in a VM or using the Windows Linux Subsystem (ubuntu)? I suspect I'll need a test clip too...

d.

I do! - Is there a potted "how to hook it up" guide?

d.

Free from bits it still behaves the same way :( The next step is to start desoldering things :'( Is there a disassembly of MOS 3.2? I'd like to work out what it's doing on soft break as that should point at where the issue lies... I'm sure I saw one somewhere but can't for the life of me find it... d.

Actually, it's nothing to do with the coprocessor, any mode other than 7/135 just hangs after the OS processor banner on break...

My master's suddenly got grumpy detecting sideways RAM using the routines in the new bitshifter's demo - it seems to get the banks with the lower sideways ram wrong more often than not... This would seem to suggest that the ROMSEL register's misbehaving? Am I right in thinking this is in the MEM CON...

Kicad is really the go-to open source cad/pcb package. Bit of a learning curve but it's very good. Even used (and developed) by Cern!

Ive used it for a fair few pcbs, and Simon Inns has done a lot with it including the latest beebscsi and the domesday duplicator.

Someone was considering cutting some (that wouldn't have the lettering on them), but there have never been any new ones made and made available as far as I know.

d.

This is the version I'm using, and it's fine with the HD disc controller: https://www.4corn.co.uk/articles/acornc5/

d.

Hmm, I installed the final 26bit release from 4corn on my a5000 via a gotek and that worked fine... Mind you, that version is OK on a riscpc too...
