Re: Pi and the Floppy Disc?

Are they for sale? I'd buy one! I'm sure if there was enough interest, he'd happily get some more boards made. Not sure on costs though - but that probably depends on demand. Likewise, I'd snap one up if available :) If I have time, I'd happily have a go at writing a RISC OS driver for this too, al...

Loose or intermittent connection of the +5v line in the cable or at the socket... The most common mouse fault on the Archie is a failing IR led, but this would fail on one axis first, and the buttons would still work.

Re: Pi and the Floppy Disc?

Modern nominal USB floppy drives can't do anything other than DOS formats.. which whilst understandable is somewhat annoying. What ADFS/Filecore would see for a {Pi Floppy) is essentialy a block device accessed over a serial line. You send a command to the 'drive interface' and you get back a bit-s...

Re: A540 - SCSI drive won't run !Boot until after entering and exiting desktop

Interesting, it sounds like the drive hasn't competed initialisation? Does *devices at the supervisor prompt correctly list the attached scsi drive?

Re: A540 - SCSI drive won't run !Boot until after entering and exiting desktop

What happens if you power up to supervisor, then do *dir :4, then try to catalogue the drive? Can you post the output of *status? I was thinking along the same line. Try cataloguing the drive from supervisor (with and without *Drive 4), to ensure the correct drive is selected at bootup and is ready?

Re: Pi and the Floppy Disc?

ADFS is built into RISC OS Not on all RISC OS 5 builds. There's no floppy disc hardware on the Pi, so ADFS isn't present on the Pi builds (or it may be present but dormant?), either way it uses SDFS for the SD card. Had anyone implemented an OLD-drive (in my instance 3.5" and 5.25" to Pi ...

Yes - most likely battery damage related, there was quite a lot of corrosion to clean up, but it's been running fine for a long time.

Re: Starting a Prince of Persia port...

Great to see the progress you've made on this Kieran. I was expecting to prefer MODE 4 version, but the MODE 2 graphics really do look good and the potential for using exile-type colour dithering (and/or NULA) would make a really unique conversion.

Brilliant work!

Re: Archimedes Iomega ZIP drivers

The DOS filesystem support in RISC OS 3 was only intended to handle floppies. It handles CD-ROMs and single hard disc partitions too. The big limit with DOSFS under RISCOS 3.1, is that it only supports single partitions and only up to FAT16 with no long filename support. (probably because FAT32 and...

Re: Archimedes Iomega ZIP drivers

My guess: Windows by default treats a Zip drive as a hard drive and installs a partition table. Quite possibly that's why the discs don't work with the Iomega driver, although it's not because RISC OS was only "intended to handle floppies" (since RISC OS was intended to handle hard discs ...

If they successfully boot to supervisor, then the roms have passed the checksum test, so they should be fine. Did you hold Delete when switching on, to reset CMOS RAM?

I suppose if you didn't care about RISC OS 2 compatibility at all then you could store the modules compressed in the ROM and have the loader run them through Squash_Decompress.

Looking at the Net module size, it's 29kb. I'm pretty sure the other modules came to just over 100kb when I counted them yesterday, so that won't fit...but try counting them on your hdd, to check.

Also, consider, do you really need ADFSFiler in there?
