Anyone on the list have a Wang 4205 terminal keyboard going begging ? Or even a complete 4205 terminal ? I will be bringing up a Wang VS45 in the next month or so and it'll be a challenge without a working terminal for the console. Thanks, -Dave

Is that why the ones I saw in the mid-80's also bore the brand name 'Ex-cell-o'? -- - db at FreeBSD.org db at db.net http://www.db.net/~db ____________________________________________________________ Are you safe?

Looking for some Apple II hardware...

by ian_primus＠yahoo.com

While my primary interest has been larger machines (Prime, DEC, etc.) for quite a while, I've begun to start working with the micros again. Specifically, the Apple II. I regret giving away a lot of my extra hardware several years ago. I have working IIe systems, but I don't believe I still have a complete II+ - I know I have one in storage with no keyboard, though. So, I'm looking for a few machines, Apple II or II+, or clones. Working or not, I'm not picky. Surely someone has raided a school sale lately and has a heaping pile of them... -Ian

The Crossbar System That Controlled MIT Trains

by evan＠snarc.net

This clearly belongs in the MIT Museum in Cambridge, or in the Boston Museum of Science. -----Original Message----- From: John McNamara <johnmcnamara1 at verizon.net> Subj: The Crossbar System That Controlled MIT Trains Date: Fri Sep 26, 2008 2:53 am Size: 1K To: cctalk at classiccmp.org During the period 1962-1966, members of the Tech Model Railroad Club of MIT conceived and constructed an unusual use for telephone equipment that functioned essentially as a combinatorial network. Specifically, they used five10x10 crossbar switches and more than 100 wire-spring relays to construct a control system for their large HO-gauge model railroad. Pictures of this control system can be seen at http://tmrc.mit.edu/progress/images.tcl?year=2002&month=5&day=26. Like all good electromechanical telephone systems, it remained in service for almost 40 years, even surviving a move between buildings. In 2002, it was replaced by an electronic system (not related to telephone systems) and retired to the New England Museum of Telephony ("The Telephone Museum") in Ellsworth, Maine, where it has been stored since that time. Unfortunately, the folks at that museum have decided to "de-accession" it, as it is not really part of their mission, and is taking up too much space. It is also likely to get damaged by future activities near its present location. If you have confirmed that someone or some organization would like it, please let me know. The deadline before scrapping begins is October 15th.

drive mounting plate

by rtellason＠verizon.net

I have here what appears to be a drive mounting plate, of the sort that what my admittedly fuzzy memory is telling me was used in the Wang PC (not yer typical clone). It's a fairly heavy bit of metal, seems to have holes in it suitable for mounting a 5.25" drive, one folded-down lip to mount it to the box with, and a bit of a tab sticking out the other side, which was probably for orientation (I haven't seen one of those for probably 20 years or more). Anybody have a use for this? If not, it goes into the scrap metal box... -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, a critter that can be killed but can't be tamed. --Robert A.

Iomega card documentation...

by geneb＠deltasoft.com

I've managed to find an 8 bit ISA SCSI card that I've identified through it's FCC ID as an Iomega PC800 SCSI host adapter. I've been unable to find jumper settings or info on this card via Google. Can someone point me to where I can find the settings for this card? Even Total Hardware 99 comes up short. thanks! g. -- Proud owner of F-15C 80-0007 http://www.f15sim.com - The only one of its kind.

In Germany: IBM Office System 6, Prozessor 6/420 from 1977

by Brennan.Barber＠softprocorp.com

This was from 2 years ago but I thought I would check in with you. Do you have any IBM processors for sale or trade? I collect IBM chips and noticed this thread and couldn't help e-mailing you :) Brennan

SCSI to IDE bridges...

Information about the Acard AEC-7720U is available on Acard's website: <http://www.acard.com.tw/english/fb01-product.jsp?idno_no=23&prod_no=AEC-772…> The 7720U includes mumble-HBA support so it does support large drives over 128 GB or 137 GB or whatever that limit is. Of course some older computers do not support partitions that large. For example, a 750 GB drive on a Mac SE/30 would need the drive broken into 375 partitions... > Any idea if this outfit combines shipping? They're charging a pretty high > shipping cost for something like this. I don't know if they combine shipping. $10 for shipping does seem excessive, especially since the things don't weigh anything. Also, those are used 7720Us and do not include the power dongle. However, the power dongle is simply a 'Y' splitter which terminates in a regular hard drive power connector and a floppy drive power connector. Your hard drive needs a power connector of course, and the 7720U draws its power >from a floppy style connector. That style of splitter is getting harder to find, but many of the folks on this list may have them on hand--or a regular two-hard drive splitter and a hard drive to floppy drive power adapter. Oh, and the Ebay guy doesn't ship internationally. I'm not trying to be discouraging; it's still a very good price, but there are some details buyers should be aware of. I feel free to point these things out since I sold the last of my *new* 7720Us ($39 + $4.85 shipping with power dongle) a couple of weeks ago. :-) Jeff Walther

PDP-11/23 available in Vancouver

by borisg＠unixg.ubc.ca

I'm in the process of moving and have to get rid of my Minc system. I'd love to keep this machine but maintenance of domestic harmony necessitates going to newer (ie considerably smaller) embedded systems for data acquisition. The complete package consists of: MINC - 11/23 + 512 Kb RAM + A/D, D/A, Clock and lots of expansion room in the box which is in the orginal rack mount and on wheels for "portability" 2 RL02 disk drives 2 RX02 floppy drives (1 mounted with Minc + 1 spare) About 10 or so RL02 disk packs 1 large box 8" floppy disk boxes Several boxes of Minc manuals as well as a set of RT11 manuals Depending on the home situation, I might have to throw in another 2 smaller 11/23 systems and a large box of 11/23 boards of various kinds. Whoever wants this can have it for free but the deal is you have to come and pick it up and also take all of the materials. The last time I had this system running was in 1993 when it worked just fine as a data acquisition front end for my Mac and room heater. It hasn't been powered up since and I can't guarantee that the power supplies will still work. I've taken photos of the system and will post them on my website once I have time. I'm hoping to be out of Vancouver by the end of October so would like to find a new home for this system by them.
