[Techtoolslist] Fluke 9100A troubleshooting

[Ian Eure]

Thanks for the info. Mine doesn't have the piggyback, part number is the type that has the built in ROM. Seems odd that it would be defective out of the box.

Looks like some parts are on eBay, I'll see if I can get the prototype one & piggyback. I suspect my 29B can program it, but I don't have the right adapter. Found the ROM on the Flippers FTP.

I just wish there was something I could do to test & make sure that's the only problem and that the VFD itself is intact.

I picked up the new in box 9100A, since I’ve been looking for one and I had an offer accepted at a price I thought wasn’t too out of line, considering that it came with a probe and clock module & was new in original packaging.

I see in the technical manual that blinking UUT/DISK LEDs are a sign of display problems, but I don’t see anything indicating what solid LEDs would mean. I opened it up and found the SCSI card
