I personally use an old 90's ITT Métrix DMM, I believe it's the MX20. It may not be a Fluke with all the desirable bells and whistles, but back in the day this was a very well regarded model. It has autoranging but that can be overriden by the push of a button.

Erm.. Now that you mention it.. I looked up and yes it's definitely the M6117.. Sorry, got the two part numbers swapped around.. To be fair, TRW lists this chip as "386SX/SLC single chip", and I misinterpreted that.. (note to self: read twice before posting)

See that M1217 chip? It's actually the CPU. Well, not quite, rather, it's a 386SX core with the supporting chipset circuitry bolted on. It seems like this motherboard could either have a standalone chipset and a real 386SX, or this ALi M1217 386SX+Chipset package.

In my head those things are indestructible enough that whatever airplane or truck was carrying it when it got bounced around bad enough to do that, is now a write off. That's what I thought too initially, but I guess I wound up being one of the 0.00001% in the "shit happens" camp. To be fair, the …

Bought a Seagate ST-296N for much cheaper than they usually go for... Only for it to arrive completely trashed. First signs of troubles came up when I powered the drive up (horrible screaching noise), so I popped the cover up and sure enough, the uppermost platter's heads got sheared off the …

Here's how I would proceed: - Get a known good SCSI (yes, SCSI, with the two switches, a LPT drive will fry the SCSI chip in your Mac!) zip drive (doesn't matter if it's a 100 or 250 drive, since all you're going to do is pull data from it) and connect it to the Mac's DB-25 port - Boot the Mac off a …

The P260's DVI port is a bit odd, it's not a fully wired DVI-D port but rather, a DVI-A port. As far as I know only NEC made CRT monitors with DVI-D ports, but those aren't very common.

Yeah there's indeed a generic OS9.2.2 image floating around somewhere (again, I can't give a direct link, per site rules), you just burn it to a CD and with the CD inside the Mac's CD drive it should get picked up by the boot picker (hold ALT/OPT), once you boot into it, you should have the option …

I doubt it would be the hard drives that causes this, I'm guessing the restore utility tries to find the machine's ID and since the QSG4 has a different machine ID compared to its older brothers, the utility then locks itself out. Theorically past system 7.x, Apple did away with the "OEM only" hard …

That probably won't change much but I've always used a retail OS9.2.2 image when I needed to reinstall OS9 on my Macs (unfortunately, I cannot provide a direct link to one such image as not to run afoul of the moderation here). It sounds like to me there's something that is tripping up the …

Yup and yup, and you can either hold the "ALT"/Option key at boot and select which drive to boot from, or go into the OS' settings, select the "Startup drive" and select which drive you want to boot from at next boot. The Alt shortcut is the same thing as striking F12 on a PC, it's temporary, if you …

I don't have a set preference, but generally speaking, OS9 does read and write on FAT32 disks, although it's gonna be capped to USB1. 1 speeds. Not sure about Zip drives (I only have one SCSI drive that is hooked to my PM7500) though but I'm guessing it's gonna be a tiny bit faster. In these …

[snip] I was also thinking of installing a zip drive to simply exchange data between PC and Mac but I'm undecided because it ruins the aesthetics and I'm not sure if OS9 reads PC formatted zips. OS9 can read PC formatted Zips, up until OS8 you needed a set of extensions (Macintosh PC Exchange), but …

Most notable scrap find lately is a Shuttle HOT-555 which works and has managed to impress me, as it's a late revision. I have the same board (although in it's "555A" revision, the original 555 had a Dallas chip), there's a patched bios for it if you ever need to connect larger capacity hard drives …

Thank you I've tried the manuals but apparently only the vesa resolutions are stated. Is there a program that I can use to check the various refresh rates? This probably will sound dumb but since it's a LG, try and send a higher than expected resolution, your monitor should show a "OUT OF RANGE" …

Thank you for the feedback. Indeed that's the procedure and I have prepared the floppy but unfortunately it did not work and I don't know why, and worst of all since there is no video I can't tell if Awdflash throws an error or what not.

Since your board tries to seek the floppy drive, there's some hope for recovery. I've faced that with a very similar board (mine was a HOT-555A Rev-3.2), I tried to flash a patched BIOS, and wound up in the same boat. I prepared a DOS boot disk with AWDFlash, the patched BIOS and a modified AUTOEXEC …
