i'd deffinatley buy one since i only have a 1mb card for my portable and as the onboard ram is bad there is a good chance the upgrade card might be bad aswell Even at $6.88 a chip…

Isn't the Portable's RAM actually psuedo-static, not static? Just spitballing, but if you could make a board that could take a BGA here's a 4Mx16 70ns Psuedo-RAM that's $5 a head: …

My 5120 doesnt have any expansion cards, and I had noticed decent cards are hard to come by, if not impossible.  Soo...  I have been thinking, I was going to design and build a R…

Thanks Joe from Des Moines. I posted an update on his medical thread: https://68kmla.org/forums/index.php?/topic/23626-medical-update-916-health-scare/&do=findComment&…

I hope Elfen is feeling better soon! Joe from Des Moines sends his best.

Hello, The 17'' PowerBook I had a while ago was badly dented on the left hand and side of the lower case. So I decided to tap the damage out with a tack hammer. I managed to tap o…

Okay. If that's the case probably what I'd suggest is going to iFixit, browsing their take-apart/repair guides, and following one just remove the top case. (The instructions for th…

Its the 17in model. As is, if you have it resting on a desk or your lap, you can't hardly tell that there is something wrong. But if you inspect the machine, yes it is damaged in i…

Might be cheaper to get a dead one in nice cosmetic condition off eBay than to try and professionally hammer out all the dents.

This is not Elfen posting but his youngest daughter, he's in the hospital for observation as it looks like its a bad allergy issue that is he undergoing. Details tomorrow when I ge…

No problem.  John from VintageMicros (http://www.vintagemicros.com/catalog/index.php) also sells small packs of appropriate feet - I can't find them on his site right now, but I kn…

Thank you david__schmidt!

You're looking for a 3M Bumpon part.  The main directory for such things: http://products3.3m.com/catalog/us/en001/manufacturing_industry/specialty_tapes/node_GSH0V016W0be/root_GS…

I managed to finally get myself an Apple //e, but it is missing three of the four feet. I did some googling and found some references to a Radio Shack item, but the website comes u…

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 …

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…

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…
