[Fwd: More interesting reading on the Apollo 11 LM] (fwd)

by tomj＠wps.com

re: choice of languages: since they were hand machine coding, the choice of high-level language was immaterial, and was a meta-language only since no compiler was used. Probably the authors were fluent MAC programmers. Maybe they had MAC OS/360 emulators/interpreters. In hindsight some things appear odd (read-only core must be physically assembled with 1's and 0's!, instead of disabling/modifying drive currents) but embedded control -- with human beings at .25M miles! -- never mind the mass-media effect of failure -- was utterly without precedent. Hell embedded digital control was novel. So -- Extreme conservatism of an kind UNKNOWABLE to COMMERCIAL programmers was always foremost is space applications. http://www.unt.edu/UNT/departments/CC/Benchmarks/benchmarks_html/sepoct95/l…

Do you have a link to the write up? I did hear about a lot of faulty caps due to a supplier that sold bad batch of electrolyte to a lot of the cap manufacturers. What formula do you need for caps? AFIK it's just a matter of buying them for the applicable voltage. Yes there are formulas for capacitanace to achive the necesssary filtering but the wrong results there won't cause them to burst.

72VDC power?

by rigdonj＠cfl.rr.com

I picked up a couple of rack mount computers last week. Most of them were made by Harris and Texas Micro and are MOL standard passive backplace type stuff. However one of them was made by Kontron and it has a very strange power connector. It's a black cylinder about 1 1/4" in diameter and about 1 1/2" long that sticks out of the chassis. The back half of the cylinder is threaded so it appears that the mating connector screws onto it. The front portion of the cylinder is divided lenghtwise into five segments. Four of the sements have holes in them with a male connector pin resessed into the holes. I opened the chassis and found that it was marked as being built to operate off of 72 VDC power and that all four connecotr pins are wired tot he PSU. Is anyone familar with the type of connector or why or where they use 72 VDC power? The computer doesn't look like anything exceptional. It has a 10 MHz 286 CPU and uses a 9" CRT in it for the monitor. The only thing of real interest in it was a GPIB card. This one was made by INES (IIRC) in Germany. I've never heard of this brand before. The chassis does have one odd feature. The motherboard sits crossways in it and there are cables that plug into the back panel connectors of the various cards (they're now on the RH side of the computer since the MB is sideways) and run around to the back of the computer and connect to connectors there.

purchasing new 9-track tapes?

by brad＠heeltoe.com

Does anyone have any experience purchasing new 9-track tapes? (seems crazy to do such a thing but I want to load some up and I thought a new tape would have more stable media/binder/whatever and not break down like an old tape might) I ordered some 1200' reels from a company in california as an experiment (the tapes cost more than the drive :-). I wonder if, in fact, they are "new". Does 3M still make 1/2" tape on reels? -brad

I haven't purchased any new in years, but if anyone needs tapes and would be willing to risk used, I have several hundred here. I have it in 3 different spool sizes, with and without write rings. Most are 6250 CPI certified. Make an offer. Shipping would be from 07848. USPS media mail is very inexpensive. Kelly

VAXstation 3100 M30 boot problem

by KVanMersbergen＠RandMcNally.com

Hello- My VAXstation 3100 M30 will not boot up anymore. It worked fine up until yesterday. All I get on the screen when I turn it on is this: < That's all. Nothing else. It will not even POST and bring up the console. I thought it might have something to do with the external SCSI connection but I'm not sure. Anyone know what is causing this? -Ken V. *************************************************************** This E-mail is confidential.
