Sorry to bump - but I think I may have found a clue. I was messing with an IBM DSAS-3360 drive which was displaying the same symptoms as the ST15230N - Phase Error. When I popped a jumper on to disable TI Negotiation, it all burst into life. Which makes me wonder - can I do the same on the...

Thank you for this advice. I'll give it a go.

I'm a menace and an idiot. I'm sorry, but it's true. I have a hard drive, from the early nineties, that was used in a store demo Mac in the UK (back then they were called Apple Centres). It worked, I moved it into another Mac, I used the wrong screw, and I popped the oscillator on the...

I think that the Gods of Retro must be smiling on me today. I found a suitable boot disk with disk first aid for my old LCIII - turned it on and… …before I could pop the boot disk in my old Mac started up from its hard disk. Very strange. All diagnostics pass, everything is happy. If it...

None on sale that I can find in the UK.

Not yet - I'll do that. First I need to get my hands on a disk which will boot that Mac, and I don't have one to hand right now. I'll take a look this weekend.

Yes. Quantum Viking II. LVD/SE

Yup - that's right. The new hard drive didn't work. Neither does the old hard drive now. I've tried the usual (zap pram). It's dead for internal SCSI - although external SCSI still works. Which is bizarre - since the LC Macs only have one SCSI controller chip.

I think that I might have partially broken my LCIII. I was trying out a 'new' hard drive in it (9GB, with a 68 to 50 pin adaptor) and now it won't recognise or boot from the old hard drive (APD shows "The Hard Drive test cannot be run because there are no drives available". If I disconnect the...

I have the adaptor. It's the jumper settings that elude me. I suspect that I need a bit more than just the adaptor!

I have a Quantum Viking II hard drive which I originally used in my PowerMac 9600 (I think - after all this time my memory fails me slightly, it might have been my G3). I don't have the 9600 any more. Is there any chance I could install it in my LCIII? What jumper settings would I need?

Okay. I guess it’s a full recap. Which is a bit of a pest. What modern options are there? I don’t want an external PSU dangling out of my LC.

Do you know of a diagnostic guide for the LC475 PSU?

Nope. As I say, the PSU looks pristine. I had a RIFA failure on an Acorn - and the computer definitely didn't work (mind you, that RIFA failure didn't so much have a crack as a blast radius). No leaking or bulging caps. Is there a diagnostic guide to help me get this PSU working again?

My LC475 has a dead PSU (I tested it briefly with the lower rated PSU from my LCIII and it worked fine - so it's definitely the PSU and not the logic board). There are no odd smells, no scorch marks, and no leaking or bulging caps - the PSU board looks as good as new. The fuse is fine - so I...

Yup. I’ve checked those manuals, and I know the rules for when and where to terminate for the Mac. It’s the additional settings for termination that those drives support which confuse the hell out of me!

Do you know what the correct termination settings should be for a Mac? Beyond just “terminate the last device in the chain”. These drives have several termination blocks covering what gets terminated and when. Even by SCSI standards it’s a mess!

My Quadra 650 has suddenly decided that it doesn't like SCSI replacement devices like BlueSCSI any more (even ones that my SE/30 will use quite happily). Whilst this could be a sign of an impending failure, it should be said that the 'Like BlueSCSI' part of the previous sentence is doing some...

I tried hiding the window `.visible = false` - but then no methods run on that window either.

I thought I'd take a break from the day job of hacking with C, and play with ReadBASIC on the Mac. It seems VERY limited - but perhaps that's me (probably is). How do I, for example, create an application which doesn't have a window? It seems like it should be possible (because in Project...
