RISCOS - Mice, 5 1/4" Drives and internal ZIP drives.
Has anyone ever added a 5 1/4" drive to a RISCPC? I'd like to add one to support DOS - I have lots of DOS software that I'd like to run without having to copy all the discs to 3.5".
Does RISCOS support the wheel (with an adaptor!) on a modern mouse?
And, finally . . . Has anyone used an internal iomega Zip Drive on a RISCPC? It connects to the IDE port and meets the ATAPI specifications! This drive was purchased during the Omega development - so I was thinking it may work with the Blitz interface - I may get time to test this later on - but any information beforehand would be useful.
Thanks - Dave H

If you've got a Stuart Tyrrell Developments PS2MouseMini, the answer is yes. There's a PS/2 Wheel driver module on their website which implements basic scrolling. It's beta-quality but works in most apps I've used.daveejhitchins wrote: ↑Thu Jul 02, 2020 9:12 amDoes RISCOS support the wheel (with an adaptor!) on a modern mouse?
I'd try the Zip drive but you might need the Partis drivers (there's a free demo). I've only used SCSI and Parallel drives.
Floppy drive wise - try it! I've heard of it being a supported configuration for the Archimedes but I don't know about the RISC PC. I'd expect problems with BBC DFS (FM modulation) floppies.
Cheers

Thanks for that . . . I do miss a scroll wheel!
Looks like the drivers are just for the external parallel interface. I really need to make time to try the ATAPI interface!
That sounds promising - as I'm only interested in DOS format disc it may just work . . .
Thank for the info - Dave H

I used to have 5.25" drives connected to an A310 back in the 80s. (!). There was a special "buffer board" that was hung from the metalwork of a podule slot that was required to drive the thing -- I suspect it was really just line drivers for the longer cabling and perhaps to sort out drive selection.

I think you might need to look at the PowerATAPI drivers, rather than the PowerZIP Drivers: http://www.partis.org/shop/main.php?sub ... ems/atapi/daveejhitchins wrote: ↑Thu Jul 02, 2020 11:00 amLooks like the drivers are just for the external parallel interface.

Ooops! Missed that, thanks Andy - I will check the Blitz board first, however!riscosbits wrote: ↑Thu Jul 02, 2020 11:16 amI think you might need to look at the PowerATAPI drivers, rather than the PowerZIP Drivers: http://www.partis.org/shop/main.php?sub ... ems/atapi/

Hi Dave
I've got a Technomatic 5.25" drive interface which came with an A3000 I bought.
It has a piggyback connector for power from the main +ve terminal and fits onto the motherboard floppy drive socket, the A3000's 3.5" disk cable connects onto it and the idc connector for the 5.25" drive fits into the mini-podule slot.
I haven't tried it yet but it looks good, see picture.

Works fine if connected to a "supports ATAPI removable media drives" IDE podule. I had one running with a Simtec IDE for quite a while. So I guess chances with the Blitz are quite good (its ATAPI compatibility was OK at least with CD writers back in the day).daveejhitchins wrote: ↑Thu Jul 02, 2020 9:12 amAnd, finally . . .

For internal IDE, you need additional software like PowerATAPI (given that it coexists happily in a master/slave config with your harddrive of course!)- if you happen to have a Power-tec SCSI podule, this might even already include it.
Have fun

So . . . Use Blitz interface - if it works then OK. If I decide to use the internal interface then I need the PowerATAPI - Right? Just making sure I understand everything correctly.hubersn wrote: ↑Thu Jul 02, 2020 2:01 pmWorks fine if connected to a "supports ATAPI removable media drives" IDE podule.

Re: RISCOS - Mice, 5 1/4" Drives and internal ZIP drives.
Yes, correct (although I have no first hand experience of using PowerATAPI for ZIP operation, only for CD-ROM operation - but PowerATAPI is definitely specced for IDE ZIP operation).daveejhitchins wrote: ↑Thu Jul 02, 2020 2:48 pmSo . . .

IIRC, PowerATAPI worked via the generic Power-tec SCSI stuff, i.e. it was a "driver" for a virtual SCSI bus and hecne SCSIDriver and SCSIFS, so it won't be compatible with other SCSI podules than Power-tec (exception: other SCSI podule with PowerROM/PowerFlash of course).

Re: RISCOS - Mice, 5 1/4" Drives and internal ZIP drives.
I now have a 5 1/4" Drive that may be versatile enough to work with my RiscPC 700. The Specifications are readily available for the Chinon FZ-506 here which gives me a good start.
I've not found a TRM or Schematic for the RiscPC 700 - OK there is a schematic on Chris' Acorns but it looks like a development drawing labeled with the project Medusa (?) with a date of 1994. Acorn's promotional brochure is dated 1995.
If the above mentioned schematics are correct the system doesn't support more that 2 floppy drives - even though you can still select 4 drives and set the STEP rate for them!! I suppose I need to check the signals on the cable!
Has anyone more information on the RiscPC 700, please?

Re: RISCOS - Mice, 5 1/4" Drives and internal ZIP drives.
I had an external double denstiy 5.25" drive connected to my StrongARM RiscPC, to read DFS and DDFS discs in late 90s, (I used this setup to write !ImageDFS) - so it should be possible with a RPC700...
Have you read the RiscWorld articles on adding floppy drives to various Archinedes and RiscPCs - they are pretty comprehensive:
