Does anyone have an idea what these IBM model numbers are like more precisely ?? 3380- AD/AE DL131 BE4 3380- AD/AE LK 3380- AD/AE LM135 AE4 3380 "E" DL 3380 "K" BP BK4 3380 "K" BP AK4 3380 "K" LM131 BK4 3380 "D" AD/AE KJ131 3380 "D" AD/AE JJ131 3390 "2" B2C 3390 "2" A28 I am particularly concerned about disks inside these machines; is there anything known ? Is any documentation available ? Thanks and regards John G. Zabolitzky

KA630 CNF?

If i read that right, there are 10 switches on this board. Switch 7 & 8 are defined as: 7 8 off off Arbiter on off auxiliary 1 off on auxiliary 2 on on auxiliary 3 Switch 7 is connected to pin 4 of the J2 connector (20 pin connector) Switch 8 is connected to pin 5 of the J2 connector. Don't have any of this boards, simply out of the manual. Hope it helps, emanuel

Novice prospectors guide

by yakowenk＠cs.unc.edu

Okay, I'm sure this is going to cost me, but... :-) I've made a first-attempt at a list. You can find a link to it, called "Machines to watch for", from my classiccmp web page, at this URL: http://www.cs.unc.edu/~yakowenk/classiccmp/ I'm open to suggestions on additions and deletions. My current rule of thumb (which is also open to suggestions) is that it belongs on that web page if there is sure to be someone who wants it enough to pay shipping charges for it, or otherwise arrange to take posession of it. While you're there, kindly glance at the Rescue Squad volunteer list, and let me know if your entry needs an update. BTW, how does everyone feel about advertising that? I've considered posting the URL to various related newsgroups, but am torn between the possibilities of increased donations and getting the attention of the wrong people. I'd rather not feed the e-bay "collectables" frenzy. Should I be shooting for "high profile", or just letting interested parties seek us out? Cheers, Bill.

30-pin SIMMS

by allisonp＠world.std.com

<I have a couple of motherboards sying about which use the SIPP's, though, <and though it's quite easy to imagine SIPP's being as easy as ever to <build, I've never seen a 4MB SIPP. Reason for that is when SIPPs were in use 256k and near the end of life for that config the 1meg parts started to be common. Sipps were out os use by time 4mb parts were getting cheap enough to consider. Often forgotten... at one time 4 or 8mb was a BIG system! Allison

Interesting typewriter

by allisonp＠world.std.com

<BTW: I also saw a Rainbow 100. Anything distinguishing it from any other <CPM/MS-DOS machine? It was a dual processor with z80 and 8088, the bus as not PC (ISA) and it allowed 768 or 825Kw of ram. It was color medium resolution when the PC was still mono. It's noteable in that it ran CP/M-80, CP/M-86 and MSdos. When Running CP/M86 or MSdos the z80 is still operational and services IO for the 8088 giveing it better performance for it's day. Allison

interesting, interesting.

More uVaxen bits... So I finally got all my wires correct in the serial connector and now get the following dialog: KA630-A.V1.3 Performing normal system tests. 7..6..5..4..3.. Tests completed. >>> Pretty cool. However on the NetBSD/VAX faq they suggest typing 'test 50' to get the ethernet address, if I type that it just says "Failure" does the port need to be connected to a network? So it turns out the _both_ systems had the Sigma Information System ESDI controller in them (not too suprising because they came from the same source) which everyone says "Ohhh, that's a nice controller." which warms my heart, but I _need_ docs. Another reader said that you can plug into the 10 pin port on the board and do some cool stuff like low level format etc etc. But I've not tried that until I get an ESDI disk. I've done lots of searches on the net for ESDI, Q-Bus, Sigma information systems, etc but no luck! I presume they've gone Tango Uniform. But that brings up another issue, I need a mounting "sled" for the disk. Preferably two sleds, (one for each disk). Anyone have any spares? Presumably I can kludge something in a pinch (or use the bottom bay which has a "floor" anyway. I did get donated a complete set of VMS documentation (5.4) but I don't have _any_ hardware documentation, again if you have said docs perhaps we can work out some sort of trade. Given the "mini-PDP-8 surge/hunt" that appears to be going on I expect this thing to be in hot demand in 10 years :-) What was the "standard" console terminal used with these in 1985? VT100? VT220? something else? On the tape drive in the BA123, it has a plain black front with a button and two LEDs, one orange and one green. TK50? Where could I get media for it? What does it look like? Thanks for all the help everyone, this is what makes this hobby fun. --Chuck

In a message dated 99-02-27 23:18:07 EST, you write: > >I'm open to suggestions on additions and deletions. My current rule > > I think at least some Mac's are something to keep an eye out for. I > haven't seen a Mac 128 since they were new! I've only seen one Mac > Portable ever. Any Mac that is in something other than a Mac case is also > a definite grab! There were kits to do it, but I've never seen one (or if > I have, didn't realize it). standard compact macs are rather unremarkable although i guess the 128 might be worth keeping since it was simply the first model. I think modified macs are far more interesting. for instance, i have a 128 in original box with all the ship group items. the mac was modified with a third party board to basically make it into a mac plus complete with scsi. even got an external floppy and flight sim with it! also have two mac512k models with a hyperdrive; a st225 hard drive and cooling fan installed INSIDE the mac. <!> very heavy but actually works. david
