Hi all, Picked up some more auction goodies this week! LSI ADM-5. I have the pdf manual for my 3a, but so far no information on the 5, anybody have a link to some online documentation! Works fine, very clean, bright cursor, no burn-in, no stuck keys and no "mold" lol 2 Sony OA-D31V-14 "Doubleheight " 3-1/4 SS 360K floppy drives. The doubleheight as these are roughly double the height of a regular 3-/14 floppies(but not "full height") I believe these may have been used in older HP's. Does naybody know if these are the ones that require a "special" floppy disks that have to be manually opened, as the drives do not have a mechanism for opening them??? An unopened Caldera Desktop version 1.0 (circa 1995!) LOL Cheers Tom

VAXstation 3100/76 SCSI disk over 1GB

If there was, I'd like to know >about it so I can upgrade the one on my desk right now! It was the first one I'd tried the 2.7g in and crash tested it trying to get IP networking going. Since that one worked I tried same on an older one and it didn't pass the crash test. A crash with the wrong driver is really bad. I assume it was factory as it works fine with a larger disk. However, I got it that way and it's a later SN. If it werent under three other 3100s plus a VS2000 and a TK50 I'd read off the VS3100-76/GPXs SN for you. All my other VS and uVAX 3100s are older and therefor completly complient with the 1GB limit for the boot disk. They also work well with larger secondary disks and I have them configured that way. IE: 500mb or 1GB system disk and larger than 1gb for user disks. Allison

I also have two M76s and both will boot larger but only one has the factory console rom fix. My solution was simple, use a 1gb disk for the system disk, second drive is a nice 2.7gb and that works fine even with 5.4-4h. It's a cheap solution as 1g SCSI drives were easy to find for a while for free. I've found for a system disk 1gb is plenty even for 7.2 and likely later as I can put the page/swap files on the second drive along with user data/files. Allison

$10K claimed for Electronics issue

by jfoust＠threedee.com

With every mania comes justifications... http://news.bbc.co.uk/2/hi/technology/4472549.stm Mr Clark, who admits he is "a bit of a hoarder", collected the Electronics magazine issues, as well as others, after the Philips Central Library in the UK - now closed - started to clean them out. "I could feel the hairs standing up on my arms. I think I've got that, I thought - although I wasn't sure." - David Clark "In the 70s, they started throwing out large quantities of these magazines," he said. "I was in my 20s at the time and thought you shouldn't throw them out because they are recording the golden age of electronics." He gave several hundreds of them a home first in his loft, then under the floorboards and had not looked at them since. - John

Still works when I power it. The only reason I'd not fly it is finding batteries. As to wweight it was remarkably light considering. Allison

Apple II/Older Mac stuff..

by dholland＠woh.rr.com

FWIW, One of the Dayton, Ohio schools around here is emptying some spare classrooms, and old storage area's of their older Apple computers. If anyone is interested in picking up a carload of stuff or so, send me an email, and I'll put you in touch w/ the appropriate person. (I believe he'd prefer me NOT to post his email address) The guy says its cheaper on the school district to give it away, and let someone pick it up, than to put it in the dumpster, and he'd rather see someone have them than dumping them. I don't know exactly everything he's got, nor am I certain he exactly knows, but I picked up a small Corolla's backseat/trunk's worth of Apple II stuff, and assorted Localtalk networking yesterday.. Said I'd see if anyone else wanted anything, and was in the area, so I am.. David

I'm desperate for a scsi drive capable of reading CD-Rs! If anyone has one, anyone at all, I'd love to hear from you! (External especailly, but I can swap drives in an external housing if needed, I guess) -- Gary G. Sparkes Jr. KB3HAG - FM19t
