Sure, by all means. I can also see if the tracks line up where they should.

Yes, that's the same drive and that sounds correct for the track counts. Disappointing that it still doesn't work. Are you able to use that drive to copy the disk the Cat will read and write (using the commands above)? Does the Cat read the copy?

I have a red ZuluSCSI (the newest RP2040-based board) in my QuikPak A4000T and it works great, though it's connected directly to motherboard SCSI.

Many folks may be unaware of the oddball WorkSlate from Convergent Technologies, a 1983 slab portable with a 6800-family CPU where everything is a spreadsheet. It was a commercial failure after seven months and Convergent took millions of dollars in losses on it. A printer/plotter (with the...

Lovely to see these things live again.

I don't think it's a caps problem with the Canon drive (though if you're able it probably wouldn't hurt), but I am suspecting the drive you mastered the floppy with. Can that drive write 720K? I used an off-the-shelf cheap Teac PC drive which can. Similarly, since you can write your own disks...

Excellent! Please let me know if the examples work. You may be only the second Cat system to try them! I'll also be interested to hear if your drive has a similar issue with the track 0 switch.

The real question is whether this has an impact on service lifetime and/or burns those systems out sooner.

Just please say the iMac G4 isn't working. It's obviously in good enough physical condition for you to attempt it, so it would be a shame if it were otherwise operational.

Heck, I still have a version I use for classic Mac OS and PowerPC OS X.

Wonder what mine would go for then, given that it has a 500MHz L2, max RAM, buzz-free PSU, CommSlot II NIC. Not that I'd sell it: I got it for a very nice price from a collector who knew it would have a good home. I agree I get way more wear out of my 7300 and MDD. However, I like the look of...

But it has an Ethernet cable. There's got to be value in that.

I have a Yosemite similar to that. It was originally running NetBSD but now I think I'll try slapping the new build of Windows NT 4 on it.

Nice setup. If I were to get one I'd get the mag cube just for historical value, but the slab is likely more practical.

That would be similar in effect to running something like MacsBug and doing an 'es' when you get an exception. It probably has a similar success rate.

Our medical records system has been down all day here. Fortunately I don't have any patients scheduled, but I can't review any charts, either.

Aw, thanks! It was fun. There is more to explore on this system.

Ouch! Hopefully your drive head didn't get caught on anything, which seems to be the way that kills drives. I've got to try to build Dwight Elvey's floppy converter and plug a Gotek into it one of these days. The Canon drives suck.

I was able to make, and then hack, disk images for the Canon Cat, Jef Raskin's 1987 "work processor." Despite what Canon sold it as, though, Raskin always intended it as a fully working general purpose computer. It has a 68000 CPU and its ROMs are primarily programmed in tForth, a...

Those look like proper numbers, so I don't think the charging circuit is necessarily at fault. I would really try it with a different battery if you can. In my experience, charging issues were more often due to battery defects than logic board ones, and they're certainly easier to replace.
