I take it from the lack of any responses that nobody has any info on MITS oem's? ______________________________ Reply Separator _________________________________ Subject: MITS Sherwood Medical S-Twelve Author: classiccmp(a)u.washington.edu at internet Date: 1/20/99 6:41 PM I don't remember if I asked for information on this computer before. I'm looking for any documentation or history of this Sherwood Medical computer. 'A Brunswick Company' is proudly proclaimed on the front panel adjacent to where it reads Sherwood Medical S-Twelve (which oem'd this MITS Altair for blood gas analysis). The Sherwood S-Twelve has eighteen slots, a heavy duty power supply and the following boards, all made but MITS: 8800 CPU BD REV 0 4K STATIC BOARD REV-2 X4 88-2 SIO REV 0 8K PROM BD REV 0- X2 INVERTER BD 88-IS SH REV 1 88 (SIOB) SERIAL TTL REV 1 MITS MODEM BD 88-MUX REV 1 MITS A/D CONVERTER REV 0 If you have any information about MITS 8800s sold to industry as in this case, please let me know.

OT: Alien Media (was Disasters and Recovery)

> It was thus said that the Great Philip.Belben(a)pgen.com once stated: >> >> I'd like to define it in terms of SI units, but the Kilogram is not too >> easy (yet). > > Really? The meter is defined (certain frequency of light from a certain > element for so many waves yada yada). Sea level is defined (don't know the > SI unit, but 780 millibars of pressure). Celcius is defined (0 is freezing > point of pure water at sea level, 100 boiling point of pure water at sea > level) and that's all you need to define the gram: one cubic centimeter of > water at 4C at sea level. That also gets you volume (liters). Well, sort of. The definition of a metre is actually 1/299792458 of the distance travelled by light in vacuo in one second. Wavelengths of the orange-red line in the spectrum of Krypton-86 went out long enough ago to qualify for this list at least! The definition of the kilogram is _still_ afaik "the mass of the international prototype kilogram" (or kilogramme, I suppose). And FWIW sea level pressure is 1013 millibars. 760 millimetres of mercury. But kilogram = mass of 1 cubic decimetre of pure water is probably accurate enough for most purposes as long as you don't have too much deuterium or oxygen-18. BTW Celsius isn't an SI unit. SI unit of temperature is the [degree] Kelvin (K, written without the degree sign), defined as 1/273.16 of the absolute temperature of the triple point of, oh no! It's water again! Again, specify hydrogen-1 and oxygen-16 and it's probably accurate enough... See. Not as easy as it sounds, but still possible. If you allow non-SI definitions, start with: Second = 1/86400 mean solar day (that changes only by a couple of percent every million years - enough that dinosaurs had a 400 day year, and ancient Babylonians observed eclipses a few tens of miles from where modern astronomers predicted them or at the wrong time of day) Metre = 1/40000000 circumference of Earth. Originally 1E-7 distance from N Pole to Equator through (I think) Paris. (Longer than SI metre by 0.02%) Then proceed as above with Celsius and volumes of water... Philip.

FYI: MEI/Microcenter is out of 5-1/4" diskettes

Looking for pointers to old Control Data software

My guess is that Control Data Systems doesn't have any 3600 software, anyway. When I worked there in the 1980's, there were no 3600 systems left in the building (although the prototype 7600 was still on the test floor). It's also been a long time since they were supporting any 3600 customers. There might be some software in a corporate archive someplace, but Ceridian is as likely to have ended up with it as Control Data Systems. In either case, they'd probably only pull something from the archive if it was for company purposes. You might have better luck with universities that had 3600 machines. Michigan State was one of them; email me privately and I'll pass on a contact there. Purdue and Northwestern are other possibilities. Re reading old tapes, the following is hearsay, but it sounds plausible to me. Old tapes have a tendency to shed bits of oxide. If that oxide lodges on the heads or tape guides, and if the tape speed is high, friction may generate enough heat to permanently damage the tape and also the heads. Thus, it is prudent to carefully clean the tape before trying to read it. ---- John Dykstra jdykstra(a)nortelnetworks.com Principal Software Architect voice: +1 651 415-1604 Nortel Networks fax: +1 612 932-8549

IMSAI/586 [ Re: Multiuser computing invented! ]

by allisonp＠world.std.com

<Seriously, how slow can you clock a Pentium and still have it run? I think it's dynamic processor like the 8080 so there is a minimum clock that is likley a few Mhz. <More generally, can you build an IMSAI style box (with more LEDs :-) aroun <a Pentium and be able to single step the processor? Well, the imsai front pannel would have little relevance to the activities of the CPU due to internal cache and prefetch. Allison

RS-6000 external cables, new - no second mrtgage req'd

by rhblake＠bigfoot.com

Dalco has RS-6000 cables that have the IBM mini 60 centronics to an SCSI 50 centronics now for $18.50 instead of the usual $45 each or more. You can see the item at http://www.dalco.com/cgi-bin/nph-tame.exe/dalco/conpin.tam?cart=99A20yke.ha… or use the search and search for item 57520. My understanding is that they are a slight backorder though, but worth the wait if you want to use that PS/2 with external SCSI units. I may actually get my 8595/XP server online again, this time with my cdroms.

PDP-8 on e-bay

by dogas＠leading.net

<rant> Ok, maybe its just me. I'm a conniving, sniviling, wheez who would probably step on my own mother to get at a cool computer (on my good days) and I spend alot of time raking though the ebayish trash to come across something tastey in a dark passed over corner of the sale. And just when you think you got a line on something, some damn smaraitan decides to post a billboard.... (no offense) </rant> I certainly don't mind those posts when they fall into the context of a discussion somewhat beyond 'Hey, everyone look...' I can understand publishing/reflecting a sale post that didn't come from public arena like ebay but I think anyone interested is capable of investing their own time searching for the things they want to aquire from that venue. Thanks, sorry - Mike: dogas(a)leading.net

Looking for pointers to old Control Data software

by Jgzabol＠aol.com

Dear Gary: This is marvellous! I used to work quite a bit on a 3600 in 1968, and it is good to hear that there is some form of revitalization for that machine. Unfortunately I have not retained any software from that time, so that I cannot help you there. However, I would be very interested in hearing any information about the simulator you wrote. Is there / will there be a report on that project somewhere ? Could you send any description ? How do you simulate the console ? What do you do in hardware / in software ?? Interested in swapping ? I wrote a simulator for a Siemens S 2002, and I have a copy of the Algol compiler that went with that machine (no operating systems at that time, ca. 1960). The S2002 was a binary-coded-decimal 12 digit machine, the one I worked on had 10 K words of core and 10 K words of drum, and all of that is in the simulator. I have compiled and executed Algol programs on it - the simulation on a PC runs of course faster than the original hardware at that time; do you have some timing estimates for your simulator ? Very best regards John G. Zabolitzky

I have been back to the library and grabbed some more books. Again, I will send to anyone who has a real need/desire for cost of shipping. People who are already getting books may wish to add some of these to their order... BTW I'd never heard of CORAL or PARLOG before. Anyone with experience want to comment?
