I've got a DT sitting in the shed which I have to get round to playing with.... I'm unsure of the specs as I only paid cursory attention to it when i got it. It was just a machine …

Bringing back an old thread, I scored the best upgrade for my G3 yet: a real Woz autography on a blank bezel!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! [] ]'> He was in town and did a…

Apart from the LCD, what's "souped up"? Click to expand... Upon further research, it looks like this example runs at 133MHz!

But then if i do this…. I will end up talking my self out of wanting a Quadra 840av. I want one ! Click to expand... Yeah,but then you'll have to see how over clocked you can …

Since it has been three years and since you've done absolutely nothing with the card, rather than letting it sit in a dark closet for all of eternity, I would suggest you consider …

Well, it's been about three years and I've done nothing with the card, and I don't think I will be. In fact, it's still resting on the dark foam shown in the photo. Suggestions o…

I'd love a copy of your diagram if you still have it!

Some LC475 run stable at 40MHz just as they are. Why not try it before you get a large 840av? And when it works, treat yourself by getting a new 840av. ;D

from the link above: I changed MC88920 to MC88916DW80, and my LC475 is working at 42Mhz perfectly. Higher clock causes unuseable serial ports (Ummm---regrettable). Click …

There's another simpler way to get to 40 MHz which used to be available from here:http://gabezing.sytes.net/LC475-40Mhz-E.html However, that site's been unavailable for a while an…

I immediately thought about Sandra Bullock . . . [}] ]'>

*says in his best Keanu Reeves voice* Arizona Wildcats.... (i'm sorry - I saw that and immediately thought of that scene in the movie "Speed")

Some of these are hiding behind my commemorative copy of the University of Arizona's Daily Wildcat from when UofA won the NCAA title. Click to expand... I still have the T-Shir…

I just found a great link to new Mustang pics: http://www.flickr.com/groups/apple_prototypes/pool/49628751@N00/ Brutally narrowed Google search with some great hits.

I have SUM II on floppies. If anyone wants it, I can image it and upload it somwehere

My SE/30 SCSi problem has been fixed!! The via connecting pin 25 of the SCSI chip to pin 9 of the SWIM chip was corroded by leaked capacitor fluids and was no longer conducting. …

TERMPWR checks out good (+5V) on both the internal and external SCSI connectors. I actually checked it at each of the inductors first and finally at the connectors themselves. I …

if you have no TERMPOWER, that means your fuse or inductor feeding the SCSI bus and/or IC is open circuit. Testing and replacement will bring the bus alive.

Z53C80 and NCR53C80 are the same part from different manufacturers. Often, one manufacturer will license the part from another. In some cases, they develop the part independently…

techknight, If i did my research correctly, I should have seen +5V across pins 24 and 25 of the external DB25 connector if the SCSI bus were working correctly. Unfortunately, I me…

techknight, thanks for weighing in. Your videos were very helpful in getting me rolling, but I'm afraid I'm lacking background information to act on your current suggestion. What…

check to make sure you have termpower at the DB25 connector as well. if not, theres the issue.

ixnay on the ematicschay request. I just realized that zuiko21 gave me the logic board connections for the 53C80 in the link in his response. I thought it was a pix of his board …

Cool. The symptoms were very similar to my problem, but on your board, the software at least detected that something was out there. On mine, SCSIProbe just blinks "SCSI Bus Not T…
