Looking for : IBM 5110 Serial IO adapter software`

My Mac+ has a stable screen :-)... Yes, yes, that is the correct way to fix it (I have done many myself)... the "whack it" comment was a tongue in cheek remark, since at one point, that was actually an apple authorized temporary fix (until you got tired of it enough to bring it into a service shop and have the joint resoldered... since back in that day, you were supposed to open your own mac... although I ignored that starting with my 128k). At one point, I even found a tech note about doing it, although, they refered to it as "tapping forcefully". -chris <http://www.mythtech.net>

> It actually got all its data over SCSI. I suppose its main application was the > very oldest compact Macs which didn't even have any PDS slot. The very oldest Macs didn't have SCSI ports... However, a company called Dove had a board that plugged into the ROM slots, and into which you then placed the ROMs, that provided a SCSI interface for the Mac 512k/512ke. They also had a memory board that had the way of interfacing to the main board... it had funny-looking sockets that "clamped" down on top of the existing DRAMs and which provided enough to bring a 128k Mac up to 512k or a 512k Mac up to 1MB. I still have both boards... -dq

Philbrick?

by Robert_Feldman＠jdedwards.com

"In 1937-1938 George A. Philbrick developed what he called an "Automatic Control Analyzer." The analyzer was an electronic analog computer..." http://www.computer.org/annals/an1982/a2143abs.htm "Model K2-W computing opamp George A. Philbrick Researches This is a general purpose computing opamp. First introduced in 1952.

While cleaning up some garage space (yes, so a Car could go in there) I came across a cache of some things I knew I had and one thing I forgot. A 2 tube module.from George A. Philbrick Researches Inc. It's a GAP/R K2-W with "computor" tubes in it. Before anybody vomits (as regards computor) could somebody remind me who Philbrick was? The name seems familliar. TIA John A.

ADA 1600 for Pet?

And they could (and indeed did) talk more or less directly to a lot of high-end lab equipment, especially HP's, although admittedly not quite at the 10Mbps rate of today... That is indeed what it is, Joe; if you actually want to use it, the DIP switch selects the unit address (usually 4 for a printer) and (if I remember correctly) the CR/LF and all-caps options. Still have a couple in fact, as well as a 1450 serial version; used one for many years to let my 8032 talk to my Centronics 101. mike

AlphaServer 1000A & EISA Config

by bdwheele＠indiana.edu

It is slightly off topic, though I hadn't seen an eisa card for what seems like a decade :) In any case, I recently got a 2nd hand AlphaServer 1000A with no disks. I put an EISA SCSI card I dug up in the machine, but its wanting me to run the eisa configuration utility. After scouring the net, I found one that would come up, but only if I burned it onto a CD. Now its complaining that It can't find a configuration file for my system board. Grrr. I suppose I'm glad EISA is dead, but...it would be nice if I could get this silly SCSI card to work. Any thoughts/hints/suggestions? Brian Wheeler bdwheele(a)indiana.edu

Wang VS

by jdonogh1＠prodigy.net

Does anyone know where I might find a Stand Alone Utility (SAU) disk for a Wang VS5E? Or maybe some OS install disks, or a old hard disk from one? VS15 or VS25 would work also-same processor (CP5)

2.88 MB floppy drive, scsi?

truck space potentially available

by mcguire＠neurotica.com

Hey folks. It is likely that I will be driving an empty 24' truck to the DC area from the Tampa, Florida area within the next week. It has a lift gate. I would like to defray the cost of the truck somewhat...If anyone needs anything hauled along the 75N->10E->95N route, please contact me off-list. -Dave -- Dave McGuire Laurel, MD
