Re: ICS Wizzo IDEFS for A5000/A4 (+A3020/A4000...) improves CF card support!

Brilliant work Jon! I'm currently away from home, but have plenty of SD card adaptors and CF cards which fail with ADFS, so will happily spend some time testing later this week. Wizzo solved CF cards, but not the SD adaptors that I have, so it will be intesting to see how these function with your fi...

Re: RISC-PC Not Working

For various reasons, I also had to make a flying CMOS chip recently in my A3010, although I didn't go as far as to replicate the clock part. Works a treat though :) _20171015_163755.JPG FYI, if you do ever have a need to rebuild the CMOS RAM circuit off the main pcb, if it's just for testing propose...

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 ...

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 ...
