Re: Plus 3 to resurrect

The 12V line runs the drive motor. It's not very regulated as it's pretty much just what pops out of the transformer IIRC. It'll probably look more like 12V under load. See what you get if you stick a car bulb across it :D

Re: Unopened 1997 RiscPC - chances of magic smoke?

There are no RIFAs in the RiscPC PSU to release magic smoke AFAIK. Make sure it's all nicely dried out, turn it on and see what happens.

If something goes on fire, turn it off :)

Re: How to clone a 'master' disc on Archimedes

So, I was just going to say, track 19 on side 0 has a misnumbered extra sector :D - > adf images won't work for that. I'd suggest converting it to HFE which will work with flashfloppy, and making the kryoflux stream available means that people can recreate the original disk if they so desire? (I sho...

Re: CompactFlash card on Castle A30x0 IDE Mini Podule

Wizzo should work as is with it. I can't imagine I'd have said it did if it didn't, but would appreciate someone testing it to make sure.

Re: How to clone a 'master' disc on Archimedes

You can write a kryoflux stream back to floppy. Whether it works or not is a different issue, often down to the drive... If you pop the stream files somewhere I can have a look and see what I think is going on?

Re: 800K Master 512 disks on a Gotek

I think (and can't check at the moment) calling them adf should work so long as you have host=acorn. I can't remember if the sector's are 0-4 or 1-5 on that... It needs to be 1-5. If not you'll need to convert to HFE with 1024 byte sectors numbered 1-5.

Re: MIDI->STM32->Beeb->Music 5000

Good work :) - I'm fairly sure that's approximately the same as Dan's interface (although I think he's using an AVR by the looks of things to do the MIDI)? It's a shame the teensy didn't work - were you using a similar arrangement with the SPI input on interrupts? The nucleo is pretty cheap for prot...

Re: MIDI->STM32->Beeb->Music 5000

Yes, basically does the same, but less parts and is (and will be) an open design. The keyboard matrix is held in an array, the STM32 has hardware peripherals that can deal with the signals from the user port as it scans the keyboard matrix (it's basically SPI), and dealing with the MIDI is just a qu...

No, but it's a better layout. I'd learnt a bit more by the time I'd done it. The 2-layer works fine at normal speeds, not sure how it'd be at high speed!

Re: CompactFlash card on Castle A30x0 IDE Mini Podule

The castle hardware has a shim - it doesn't have an IDEFS, it just runs with ADFS. I ran wizzo quite happily on my A3010 with the castle card and it just worked! However, I do have to say, now you're all making me doubt my memory! :)

Re: CompactFlash card on Castle A30x0 IDE Mini Podule

No, you need those in there as I think they allow filecore to speak to the interface, then wizzo basically can be used in place of ADFS. You'll need to re-bodge the ROM to include both. There's a version of wizzo that runs from ROM on the A5000 - I'd guess it'll work on the A3010 too as it's the sam...

Re: CompactFlash card on Castle A30x0 IDE Mini Podule

So, the Castle adaptor suffers the same issues as the onboard IDE in the A3020/A4000/A5000 and even RiscPC. It uses native ADFS rather than IDEFS and what it gets on with is dictated by the CF card... You can load wizzo from floppy and that'll get it playing properly with most things. The ROM has so...

Re: Raspberry PI Co-Pro 6502 more memory?

The extra memory on the master is very different to the RAM on the coprocessor, so unfortunately it won't let you run things that were developed specifically to work with the master (like SCR). The coprocessor just uses the computer it's connected to for inout/output (display, keyboard, disks etc). ...
