Re: IDE interfaces - hardware details

Is it feasible for the ROM to be adapted so it presents itself as an ADFS filing system? (Which may involve accepting some ADFS shortcomings, like lack of partitions etc.) I think you have an original V1 card. So you should be able use the ROM image from the original ZIDEFS distribution, which has ...

Clearly Acorn changed the ROM wiring between the A310 and A3000, will the board work with the standard RO3 ROM carrier board in the A310, as this connected up the higher address lines? The V1 ArcFlash fitted in my A310 fine, it effectively has the carrier board integrated, you feed the upper addres...

That's interesting about the ROMs... thinking about it, they're also 32pin 8-bit ROMs so would need some work to get into the A3020... so file copying sounds best.

Re: Possible HD problem on A7000+

With ADFS, Filecore and BASIC unplugged, nothing much will work.

I'm surprised the delete (not backspace) during power on isn't doing something.

Can you try *rmreinit BASIC (this should mark BASIC as not unplugged), then a power cycle. Then check the output of *unplug again.

Yes, did that with delete power on, no change whatsoever. Your question on unplug....are you asking for a status for the computer with the HD unplugged?
*UNPLUG at the * prompt should show which modukes are unplugged. The *status you posted looked a bit short.

At the moment it's just on the end of a cable plugged into the 5 pin header on the module. Long term, not sure, probably attached to a din socket on a podule backplate.
