The VAX8600 was targeted at large IBM sites, so they put in an oversized power cable and receptacle, that was the same as for the IBM equipment they planned to replace. So the 8650 I have here have a cable and receptacle specified for 410V@32A/phase, but it runs just fine on 16A/phase. And our KL-10 sat on this *huge* 410V@63A/phase thingie. That receptacle was just large enough to be silly. And the power cable is not something you carry around in your hand...

Do you have any more details about DSV11 operation above the rated 256 kbit/s? What exactly is the real limit and what are the limiting factors? I have the technical description (EK-DSV11-TD), but it isn't absolutely clear. > The DSB32 is also > not an option if you have a VAX 7000 I'm not using a VAX 7000 (and don't consider it a real VAX thanks to LSB and whatever else they broke in NVAX+ when they fit it into an Alpha pinout), but I'm curious why. I mean, how is DSB32 special? I recently searched for DSB32 on Google and came upon a posting by you saying the same thing, there you also said it had something to do with the way its firmware locked memory. What exactly is wrong with it? Does it strictly follow the VAXBI spec or was it given an exception? Does it use IRCI/UWMCI pairs exactly as the spec says or is it broken? Or is the VAX 7000 kludge the one at fault here in that the memory is not presented to VAXBI as prescribed by chapter 8 of the VAXBI spec (the Must Respond Set for Memory Slave), and DSB32 just happens to be the only device that uses everything that the spec says is allowed? Or will all VAXBI devices that use BVP (interlocked queues) not work on VAX 7000 because its VAXBI interface to memory (through XMI and LSB) does not support IRCI and UWMCI? That would be DSB32, AIE/AIO (DEBNx TK50/TK70/Ethernet), all BI-to-CI adapters, DWBUA if some UNIBUS device accesses memory with DATIP-DATO (which turn into IRCI/UWMCI), what else? You said DMB32 should work, I guess it isn't using interlocked queues. But then again IRCI and UWMCI are the in the Must Respond Set for memory nodes (section 8.2.2), so it would just mean that VAX 7000 is not a real VAX as I've been saying all along. > I suspect that for T1 speeds you'll be stuck using an > Alpha or possibly a DECnis, Well, neither Alpha nor DECnis firmware run 4.3BSD-Quasijarus, so those are not my options (I love my 4.3BSD-Quasijarus based router and won't give it up), but there is one more option: build a new sync serial card! We can even build both Q22-bus and VAXBI versions. MS

GEEEEEEEEEEZE!

by jwest＠classiccmp.org

Ok I'm extremely irked. Friday afternoon the classiccmp server decided it didn't have a slave drive. It has done this once or twice before, for some reason the system can't see the drive anymore so it flags it as non-existent. Usually after a reboot it goes fine for a few months at least. Most odd. I'm guessing it's the crappy Western Digital 160gb drive I bought. Don't think I'll be getting any more Western Digital for a while. It came back up friday afternoon and I saw a few emails go through the list so I assumed all was well again. Stupid Me. So I promptly decided to ignore the list for the weekend, had a very full weekend with lots of other stuff (work & home) to do. Sunday night I noticed that the list hadn't passed any traffic since friday night. First thing I checked was the drive, but that was ok. It was a very bizzare odd problem. Sendmail appeared to be working fine but mailman wasn't queueing any messages. Both inbound and outbound mail were definitely working though. Odd - the pid files for mailman were dated in the future, but the system date was correct (and had been). I tried pretty much every trick I could think of to no avail. I finally gave up around 1am and said the heck with it, I needed sleep and have some WorkStuff to take care of. Tonight will probably be an all nighter due to a different work-related server issue. I had even tried re-installing mailman 212, figuring a binary got corrupted in the fiasco friday afternoon. No Joy. Looks like all messages were sent to the shunt directory, which means a mailman executable failed. Some message about can't unicode because bytes 0-4 are not cardinal. Ick. So this morning I upgraded to mailman 2.1.4. That seems to have done the trick. Pid files are still dated in the future though. What fun. All appears to be back up and running. I apologize for the extended outtage. You'll forgive me if I ignore this list for a few days, I just don't want to think about the server for a bit. It's self-interest, I figure if I stay away from it for a few days I won't be so ready to unplug it and chuck it out the 2nd story datacenter window.

Where's Eric? was paging Eric Smith

by rigdonj＠cfl.rr.com

hi all, Eric bought an item that I had on E-bay about 6 weeks ago and I've emailed several times but I haven't gotten a response. After yesterday's posting I heard from a friend of his that also hasn't been able to contact him. Is there anyone in the same area as Eric that can check and find out what's happened to him? I had a phone number for him and I just tried calling it and the guy that answered said that Eric doesn't have that number any longer. It sounded as if he's gotten a lot of calls for Eric. Joe Eric are you out there? If then you need to contact me. I've sent you two E-mails and haven't gotten a reply. Joe

Strange Keyboard

by lyosnorezel＠yahoo.com

Hey ya'll... please take a look at these three pictures: http://geocities.com/lyosnorezel/keyboard1.bmp http://geocities.com/lyosnorezel/keyboard2.bmp http://geocities.com/lyosnorezel/keyboard3.bmp The first two show the keys, the third shows one of two connectors that it apparently interfaces the computer with. The two "plugs" are 8pin jacks... like cat5 but in a wider, more spread out form. The most noteable things about this keyboard are as follows: Interesting Keys: Cancel Move Help Action Over Type Finish Copy Lock Code (instead of ctrl) shift + 6 would give you the "cent" or "penny" sign (a "c" with a line though it) F1, F2, F3, F8, F9, F10 all have lights Return instead of Enter 1/4 1/2 fraction key... 1/4 is on top... key is next to "P" Number pad: GO Next Arrow Pad: Mark Bound Anyone know system this keyboard is from? The only markings are from the company "Datapoint Corporation" "Model No. 93-1222-001" "Serial No. 978870" It's UL and CSA certified. Other then this there are absolutely no markings. Thanks.

I have this service because it is the lowest-priced business Inet service from WorldCom/UUNET (now called MCI). It had to be a *business* service from them in order for me to get a Class C NET from them, and it had to be WorldCom as they were the only ones who just gave it to me without charging me an extra arm and a leg for it. (Also WorldCom was cheaper than all other business Inet services, though again I only considered business services as they are the only ones that give full Class C NETs.) Except for being slow (but that's fair, you get what you pay for), I'm very satisfied with UUNET and won't switch. MS

R80/RA81 diagnostic experience?

R80/RA81 diagnostic experience?

by brad＠heeltoe.com

[resend - looks like original got lost this weekend] Hi, If anyone has diagnostic experience with an R80 or RA81, I'd like to pick your brain a little... If this is better done off line, email is fine. I suspect not everyone is interested on how to revive an R80 :-) (why *I* find it infinitely fascinating is something I'll never understand) I have an R80 which does not spin up or come ready: - All of the voltages are good (all the ones I checked anyway). - The drive belt had come off but I managed to get it back on - I can't seem to get it into diagnostic mode; the 8 leds' on the bottom pcb show 0101 0101 (hex 55). - When it powers up all of the external lights go on and stay on. - if I reset (click the switch ont the pcb to "R", the lights go out - if I then push the run/start it lights and after about 5 seconds the fault light comes on and run/start goes out. - if I push the fault light all lights go on and then the right most one stays on - push fault again and they all go out (I can then repeat the run/start sequence) I'm guessing the above behavior means the micro is operating, but then I set the rotaries to "FF" and hit 'enter' (i.e. put the toggle to 'E') the led's don't change at all. The manual says they should flash and change as a I enter diag mode. I wanted to use diag more to force a spin up but no joy. Does the unit have to be connected to a controller to go into diag mode? I have an RB730 which this connects to. Connecting is does not seem to really change it's behavior. -brad

R80/RA81 diagnostic experience?

by GOOI＠oce.nl

I am not sure that removing the brake will help. I once heard the following rumour: the brake in combination with the 'heavy' motor makes sure that the disk platters always rotate in the same direction, never for a short instance in the other direction (vibration, power flutter, whatever reason). Rotation in the opposite direction, for any short moment, will cause the air on which the r/w head fly to disappear and result in an immediate head crash ... As I said, it is a rumour I once heard a few years ago.

OT - Panasonic LDV-1000 Video Disk Players NOS

I just got a call from a friend of mine who has a number of NOS Panasonic LDV-1000 Video Disk Players. These are the type that were used in some of the early video games like Cinamatronics Space Ace. Is there any interest in them from list members? Apparently the only thing wrong is that the boxes got damaged but the units themselves are fine. Let me know via email if you are interested.

After wanting a Commodore 64 SX for such a long time, a kind man finally gave me one. (it was the victim of a garage-clean out. I got it back home and it worked fine for a while. later that night I was writing basic programs and this strange color washed over it's little screen then it went blank. Cycling power did not restore any picture. I left it unplugged overnight, (thinking the problem may have been heat related) but it's still in the same state this morning. Any one have any knowledge?

It's a lever on the HDA, which you should turn to unlocked. Does the R80 have the terminal interface on one card like the RA8x drives do?

HP item wanted

by jwest＠classiccmp.org

I figure there's pretty much zero chance of this, but thought I'd ask :) I have an HP 7906 drive that is rackmounted in one of the "newer" style cream colored rounded edge HP racks. I want to mount it in one of the older dark grey HP racks. The mounts are completely different. So, I'm looking for 7906 drive rails that go in the older style cabinet. I do have L brackets that go in the older cabinets, but with 7906 drives it's pretty important to be able to pull them out a bit and work on the bottom. Anyone have a set for trade?

That's what I thought, but I don't actually have a copy of the standard, just my well-thumbed copy of Charles Spurgeon's "Ethernet" book. It says the stripes are 2.5m apart but transceivers can be placed at 5m or 7.5m or any multiple of 2.5. Well, 2.5 is a multiple (in the mathematician's sense of 1 x 2.5) so maybe 2.5 is OK. > But I have actually never really understood why.

The reason for the 2.5m spacing is that it's an odd fraction (about 1/19th) of a wavelength, so when you put taps on the cable, the small reflections caused by the discontinuities are out of phase and don't tend to be additive. -- Pete Peter Turnbull Network Manager University of York

They're totally useless for anything else. Joe More: "The ROMs used in the 9835 are rather unusual. The ROM carriers look exactly like the ROMs for the HP 9825 but without labels. But instead of only holding one ROM, each carrier has sockets for four ROMs. The individual ROMs are small square boxes similar to those used in the HP 85. The 9835 ROMs come in sets of 1, 2 or 4 individual ROMs and the ROMs can be mounted in any order in the carrier or in any position in the 9835. The fourteen operating system ROMs are similarly mounted in a pull out drawer on the left side of the 9835. Flash! I've just learned that one collector has a 9835 with ROM drawers that hold six ROMs each instead of four. That's something that I haven't heard of before.

KL-10 question

by ggs＠shiresoft.com

Hi, Does anyone know how much 3-phase power (at say 220v) a KL-10 requires? I just acquired some commercial space to move my collection into and I noticed today that there are several 220v 3-phase power drops that I hadn't noticed previously. I'm kind of hoping that I'll have enough 3-phase to be able to start resurecting my KL-10, but I need to know how much I need. Thanks. -- TTFN - Guy

I think somewhere around 40A per phase should do it. We ran our KL-10 on 410V 63A/phase, but that was a bit overkill. But I'm also pretty sure that 410V 16A/phase was not enough.

9-track tape drive "O" rings?

by brad＠heeltoe.com

Any one have thoughts on 9-track tape drive "O" rings? The O ring on my TS-11 was under compression for some time and appears to have stretched to the point where it is too large to fit a tape on the hub. I'm guessing this is a common problem. I would think these O rings are pretty common. Does anyone have a source? -brad

weird find: papertape "patch" puncher

by waltje＠pdp11.nl

Hi all, Recently I found this really cute, but weird-looking thingie. It seems to be a handheld tool that allowed operators, field engineers and so on to manually punch a bit of code onto paper tape, or to modify (patch) an existing tape. It was made by, or distributed by "Data Processing Accessories" in the U.K. Ideas, anyone? --f

I'm fairly sure it would, and that's what I meant when I mentioned ribbon cable. Didn't der Mouse suggest that? I have a Newbridge ATM Route Server which is a Sun chassis mounted in a Newbridge box, and I'm fairly sure it has a similar arrangement to connect the Sun port to the panel on the Newbridge case. I'm a great believer in adhering to standards. Most of the time :-) In this case the standard says, in effect, "use this cable and this layout and it's guaranteed to work". It doesn't say it's guaranteed not to work if you don't :-) -- Pete Peter Turnbull Network Manager University of York

Source for PDP-8/E console lamps?

by wmaddox＠pacbell.net

Does anyone know of a source for replacement lamps for a PDP-8/E console? I have an otherwise immaculate console board that I would like to use in its original condition, e.g., w/o an LED conversion, but one of the bulbs has been broken, and, at any rate, additional failures are likely. Thanks, Bill

The size of the shell is between a DA and DB, and it >has 19 pins. Are you sure? Are you thinking of the same cable that I am? I just did a quick check, and I found via Google a page that gives the pinout for the Mac's PC Compatibility Card's cable. It shows it as a 26 pin connector. I'm no longer at work where my cables are, so I can't physically inspect them. I thought the connector on the DOS Compatibility card was the same "physical" connector that is on the PC Compatibility card (although the cables, and I believe the pinouts are different). Again, I can't physically check mine, so I can't be 100% sure. Maybe the DOS card version was different (I know the cable for the DOS card is a 4 headed cable as it breaks out the joystick via the cable, while the cable for the PC card is a 3 headed cable with the joystick port residing on the card itself). And of course, Apple had a 3rd style card for the Performa 630/640 DOS model. I haven't really played much with mine of that model, so I don't know what it has (actually, I seem to recall that it didn't use a loopback cable at all) And then there are always the Orange Micro versions, all bets are off with those. I've never really played with them. But maybe you are thinking of a different card then I am. Apple also had an Apple IIe card for the Mac that had a loopback cable. I don't recall what it has for connectors. And I have no idea what possible cards there were for the Apple II series, or what possible other similar cards were for the Mac beyond Apple's, Orange Micro's, and Reply's (which was really the same as the first Apple card as it was built by Reply and first only available from Apple, later to be available directly from Reply) -chris <http://www.mythtech.net>
