Re: Variants of ADFS

Thanks for the explanations. So, in an ideal world, when ide cf drives were added, adfs should have evolved into idfs with a different (unique) filing system id, and mmc drives into mdfs with a third id. They still couldn't have been used simultaneously, and switching between them would have overwri...

Variants of ADFS

Having just ordered a beebscsi mini, I've been struck by a thought, and I can't be the only person for whom this would be of benefit. There are now at least three variants of ADFS - 1.x0 for real winchester interfaces (and beebscsi), 1.x3 for IDE (and CF) interfaces, and now 1.57 for HD images on th...

Re: LOLPRICE

So what makes him think his copy is worth £30.00 ? Simple! It's in its original cardboard case (complete with authentic clippings from magazines). Just be thankful it's not in cellophane or he'd be asking £45. Can anyone tell what's written on the disc label? I'm pretty sure it doesn't say "Zalaga".

Re: ST506 HDD woes

It's odd that your drive's giving a "no index" error code, given that it's not even managing to spin the platter. You'd have thought it would give one of the motor errors in preference, as this is the more fundamental problem. Almost as if the controller doesn't know it's not spun up. Particularly s...

Re: ST506 HDD woes

The clicks are the mechanism to unlock the head actuator. When the head parks, it gets latched behind a little lever (that's the "relay" click when it spins down). When the drive's up to speed, a magnet pulls this lever out of the way so the head can move (the "relay" click on spin-up). I'd guess in...

Re: ST506 HDD woes

I must admit I'm guessing, but all my Rodime drives have a pair of pins, with collars on them, about 5mm apart, with blobs of solder on them. On the 3065 and 3085 they're in the corner near the two voltage regulators. My guess is that they had the led soldered to them for post-manufacture testing an...

My R140 and A540 run fine for riscix with ethernet in slot 0 and scsi in slot 1.

On the downside, I've just tried to get the RO3000S out of my A680 working, and the heatsink on that gets even hotter. So it's pretty unlikely the problem on the RO3065 is indicated by a hot heatsink. On the upside, I've just managed to successfully format and verify the RO3000S, which I had previou...

Re: ST506 HDD woes

Looking at google images, it looks like it's a motor driver chip.

Unfortunately, the ridges of the heatsink are stopping my ir thermometer reading properly. However, the voltage regulators are reading 35-ish and it's considerably hotter to touch than those.

Re: RISC iX on ST506

It was years ago, but pretty sure I managed to boot RISC iX 1.15 from an ST506 attached via podule to an A3000 (4MB/ARM3). The podule ROM contains only a module to provide the "Harddiscs" configure setting, so "dumb" as regards the controller itself, I infer. So if your Computerware has the same co...

It actually works at all on an A5000? I was formerly under the impression that it couldn't cope with IOEB (which didn't exist at the time) and would die horribly. Presumably, floppy and ide won't work; I'd always assumed podules wouldn't either. Now I'm going to have to give it a try, and see if I c...
