TK50-GA external SCSI tape unit + Microvax 3100 Desktop

3com 1625-0

by spedraja＠ono.com

Dear fellows, thanks to all for the messages received until this moment about the MV 3100. With independence of this lovely machine, I have one new question. This can be difficult, I've located only 4 hits in Google and all of them referred to catalogs. Somebody has one 3com 1625-0 Coaxial FMS Hub ? I just received one. It's supposed this item has one variable voltage power supply that covers from 110 to 220 volts. Right ? It has too eight coaxial connectors, one AUI connector in the back, and... a couple ot mini-scsi connectors, one male and one female. The most dammned strange combination I saw until this moment. Do you have some info of interest about this item ? Thanks and Greetings Sergio

Normally this would be an understandable slip up, but having supported DEC synch cards for more than one hand's worth of years I cannot imagine how I let that one slip by. I'll just go and find a piece of wall to hammer my head against :-) Antonio

If you're not in the area, then it's because somebody else who wants one might be closer to you. Would you not read similar messages if you were looking for the same item (not necessarily in the same area)? If you have one but don't want to get rid of it, then obviously you've already gone through the process of acquiring said piece of hardware and may be able to offer helpful advice.

TK50-GA external SCSI tape unit + Microvax 3100 Desktop

>> The machine has two scsi buses or ar least two SCSI connectors back, >> one large and another of lightly minor size. > >I cannot think of *any* MicroVAX or VAXstation that >has two SCSI connectors of *different* sizes. It has two connectors of Centronics type. One is a large Centronics type connector, over the three MMJ connectors. The other one is, seeing the CPU in its back, at the LEFT, covered by one semiespheric cover. This is a "short" Centronics connector. I have the TK50 connected actually to the large Centronics connector because is the same than the manufactured with the TK50. But this don't work, at least by now. I have no cable to connect the TK50Z-GA to the short Centronics connector. The central unit only put "Microvax 3100" in the front. Is a desktop, not a tower. Thanks and Greetings Sergio

FLUKE?

That's probably > the algorithm the programmer used to sort the list of files. By way of description Standish says in "Data Structure Techniques:" "Let A[1:n] be an array of n numbers. ... Make repeated sweeps over the array A[1:n] from left to right. Upon detecting any adjacent pair of numbers A[i] and A[i+1] not in proper order, exchange them A[i] <-> A[i + 1]. When a pass is completed with no exchanges having been made, the process terminates. " I believe it's called bubble sort because the lesser numerical values tend to "bubble up" to the top of the array.

I have a DV-31BTB-A which I know is a MicroVAX 3100 Model 20. Yours, according to the Systems & Options Catalogue I have, is a MicroVAX 3100 Model 10. On the back of mine there is (looking at the back): at the top middle: a DB37 labelled B2 (this is a socket with 37 pins) (I don't think this is available on the Model 10) in the middle row (from left to right) a connector labelled (4-11), this is for an asynch card (DSH32 I think) This is the same "style" as the SCSI connector (i.e., no pins) but is smaller. It is *NOT* a SCSI connector. another DB37 labelled DB37 this is over and slightly to the left of the 3 MMJ connectors. a final connector on the right, labelled with a diamond and a horizontal line through the right hand point. This is the SCSI connector. This connector is the only one that is identical to the connectors on the TK50Z. This is over the printer connector. Having said, if you have the right SCSI cable (i.e. the same connector at both ends) then I don't see how you can possibly have connected to the wrong place. (And it sounds like you have used the RIGHT hand connection and just are unsure what the other one is). BTW: The TK50Z box has two SCSI connections. It does not matter which one you use, but you *must* put a terminator on the other one if you expect the MicroVAX to see the tape drive. I've found a manual with pictures of the connectors. I can scan some pages on Wednesday and email them to you directly if necessary. So a few checks: -- are you using the correct (RIGHT hand) connector? -- Is the unused connector on the TK50Z filled by a terminator? -- What ID is the TK50Z set to? (Avoid 6 & 7 ... the CPU uses one of those ... I forget exactly which because it varied from system to system). -- Avoid any ID used by the existing drives, SHOW DEVICE will list these. The external SCSI bus may well be independent of the internal bus, in which case it will not matter, but again I cannot remember for this system. -- If it still does not work, what to the power up tests say? The error code (if any) should help to track this down. Antonio arcarlini(a)iee.org

FYI: AT HOME

by mranalog＠attbi.com

Hi All, If anyone is expecting mail for an @HOME.com customer, you may have a small wait. @HOME shut down about midnight local time on Saturday. I was very lucky (I guess) because I was able to get back on the servers Sunday morning to change my account. I am no longer mranalog(a)home.com, I am now mranalog(a)attbi.com. AT&T says that some customers may be out of service for as much as 10 days. Of course, my service was back just long enough yesterday for me to resubscribe to to a few discussion lists and then it was out again. This morning sending mail seems fine but receiving mail is painfully slow.

PDP-8/E bulbs

You may also > be able to find them at: http://www.digikey.com Hmm, I'd not be too sure about that. I believe the correct bulbs are 12V or perhaps 14V, T1-3/4 bi-pin, 0.04A (that's 40mA). I've seen 14V 80mA bulbs in a few places, but I'm not sure if they would be "safe" in the panel - they'd draw twice the current and I'm not sure if the driving transistors are rated for that. Anyone know? (I have a panel, but not a print set). If it's any help, I found some of the proper bulbs for my -8/E recently, and they are marked "OSHINO-1 12-09169" or "PL10161 1209169". I think the 12-09169 may be the DEC part number. On test, they draw between 30mA and 35mA at 12V, and between about 35mA and 40mA at 14V. The ones I've found in the Farnell catalogue (cat no 329-216) seem to be made by EBT Technologies, part no 7382, and they're 14V, 80mA, 1.12W, 3.8 lumens, nominal life 15000 hours, priced around 50p (about 72 cents) depending on quantity. I found the same bulbs slightly cheaper in the CPC catalogue, for those of us in the UK. -- Pete Peter Turnbull Network Manager University of York

>Anybody got one (see subject) they don't want? Do you want BNC, RJ45, or AUI? I have one that is BNC and AUI, and one that is RJ45 and BNC, and one that I think is ethernet that is BNC only. The BNC only one is the only one NOT in use, the others are in machines. I can part with one, but it will mean swapping the machine off the network, so I can't part with it for nothing. If you have good Mac or Apple stuff I can consider a trade, otherwise I can sell it to you (I am not sure what a fair price is, but it will cost me about $25 to deal with replacing it and the machine it comes from). -chris <http://www.mythtech.net>

Is it a Lisa or Mac XL?!

by dhquebbeman＠theestopinalgroup.com

> I understand discontinuing a product but could never quite figure out why > you would actually destroy equipment. I mean what is the point? I'd imagine they were concerned about 10,000 MacXLs cutting into the selling of Mac 512ke & Mac Plus models... OTOH, if it happened during the Jobs era, no logic or reason was likely involved; Jobs has a proven track record of killing Apple products he personally dislikes. But pepsiboy may have been Lisa's nail-in-the-coffin, I just can't recall... -dq

I'm not in the area. I do have an enclosure for a MicroVAX II, and some boards (CPU and some RAM) I believe I tested the CPU, and it's working. The RAM may not work with that specific CPU, and the enclosure has power-supply problems. (basically it's all left-overs from when I was trying to get parts for mine) I don't want to ship, though, since it may as well be a 3-foot-tall block of solid lead.
