Thanks Apart from my systems being 11/94's (Which I am not sure matters) That looks good.

Empirical evidence, from visual inspection of the 11/84 I use for media transcription. Considering where I got it, this is almost certainly not factory configuration, but was almost certainly configured under DEC maintenance. Slot 1: M8190-AE KDJ11-BF Slot 2: M8637-BC MSV11-JB Slot 3: M8637-DF MSV11-JD Point of interest: I got this system when it was decommissioned from production work, in 2004. The other /84 is sitting behind some of my Spousal Equivalent's craft stuff, so I couldn't check. I do not move her toys uninvited. :^) Doc

KZQSA does more in real life than it's supposed to. I have one in a VAX 4000/200 that I use to run CD-ROMs (the VAX wouldn't start up from a Plextor 12x, but a Toshiba 4x is fine), and prior to my HSD05-AA hack it was running a Seagate 4GB disk. Not fast, but it worked. Not worth $100, but since you have it it will most likely function. Was it der Mouse or VAX9000 who has the Qbus MSCP SCSI card kit in beta?

I initially thought disk drive problems again, or the pack got clobbered during swap-out for some reason. However, a little investigating quickly showed that even the most basic ten-word TTY check program would not deposit or run. In fact, when depositing or examining sequential locations I found the address display would increment from 0200 to 0001. 0577 would increment to 0400, etc. So something is wrong with address bit 4. I pulled all the boards from the backplane except the CPU set and it still does it. Now I've got to fix the hardware! Sigh. Meanwhile I have been SIMH-building a new OS/8 image from scratch for two drives. After much struggle I have the RL20 handler installed (which has logical drives R20A,B,C,D; the RL21 handler with R21A-D, and I had to omit the last 20% (the "E" drives on RL2E) because OS/8 can only allow fifteen handlers and space is needed for (at least) the R2SY system handler, TTY, SYS and DSK also... reminds me of Gates' "640K should be enough for anyone". -Charles

Well, I'd like to know how much, but I expect shipping will be uneconomic. Please don't use too much of your time. I remember the cabinets as about 2 metres high, though maybe that was two 1 metre cabinets on top of each other. I suppose if I didn't stack them I could use the top as a worktop.

The Last of The Line

by RodSmallwood＠mail.ediconsulting.co.uk

Hi There seems to be some differing views as to how the boards would be arranged in an 11/94 to use 11/84 CPU Board and memory. I'll describe the 11/94 box I have. The box has label saying 11/94-EF The first three slots in the first nine slot backplan have four edge connectors. In the space where the other two edge connectors would have been are IDC connectors for ribbon cables going to the front panel. The rest of the slots (6) in first nine slot backplane have six edge connectors. The second nine slot backplane has nine slots with six edge connectors in each. The forth slot has the M8191 Unibus controller in it. The main discussion seems to be which comes first the cpu or the memory. There is also an issue around, are the first three slots a Q-Bus or not? Currently my understanding is any M8190 CPU and any M8637 memory So Slot one: M8190 Or M8190-AB 15Mhz Or M8190-AE 18Mhz Slot two/three MSV11-JD (1Mb) x 2 or MSV11-JE (2Mb) x 2 So can we get to a consensus as to which boards in what order are known to work?

What do you mean "unusual amount"? I've been running one 11/83 like that for the last two years until today actually, when I upgraded to 4 megs. :-) I used to run my 11/84 like that as well.

Floppy configurations on IBM PC 5150/5160

by mbbrutman-cctalk＠brutman.com

The standard floppy controller can drive up to four floppies, two internal and two external. And the motherboards of these machines have dip switches that allow you to tell them how many drives are connected. But those switches are just a simple count of drives, not which chain the drives are connected to. Normally I see these machines with two internal floppies, and nothing else. On the 5160 I have here in the office I am about to add an external floppy using the external connector on the floppy controller; the machine has a single drive installed internally now. How does the BIOS handle this situation? If I tell it that there are 2 drives will it try to figure out that one is internal and one is external? Do I need device driver help, or is this something the BIOS tries to handle? Is there something on the controller card I am supposed to do to tell it how the drives are connected/organized? Mike

Semi-OT: VCR help?

by mouse＠Rodents.Montreal.QC.CA

I've got a VCR repair problem. (I thought it was just a broken drive belt, but apparently not.) Since this isn't really very on-topic (I doubt it's even ten years old), I'd prefer not to discuss it on-list. If anyone would be willing to lend a hand by email, could you write me off-list? I've set a reply-to pointing to two of my addresses, which between them give about as good a chance as is available that mail will actually reach me; in case the list mangles the reply-to, this means mouse at netbsd.org as well as mouse at rodents.montreal.qc.ca. /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse at rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B

Hi I think most software people would agree but that hard fact is that main memory is way behind processor speeds. This means that the more compact the instruction stream is, the faster the processor can run. We are quickly reaching the limits of clever caching, even for CISC processors like the X86 machines. I'm not saying that RISC machines are dead, just the opposite. Every X86 machine today has a RISC engine inside. I expect that the next generation processor will be even more CISC like and less RISC like to the external software. Memory bandwidth will dominate choices.

Dolch Ruggedized laptop Power Plug?

by ethan.dicks＠gmail.com

Not 10 years old, but definitely counts as unusual hardware... I bought a Dolch A320T ruggedized laptop at Dayton from a friend who was in from NJ and selling a few rows away from Dan Cohoe, but part of the reason it was so in expensive was that it didn't have an AC adapter. The laptop came with a hand-fashioned bit of cut PCB with leads, meant to plug into a lab-top bench supply (19V @ ~3A), but I'd like to at least get a "real" plug for it. The problem is that while it looks like an "ordinary" 2.5mm co-ax DC power connector, the center pin is mighty fat. My question is, how does one describe these sorts of connectors in enough detail to get the right part when ordering one? A standard, modern Dell PA-12-type brick pumps out 19.5V @ 3.33A, so that's not so much of an issue, just locating a mating connector is. Thanks for any help determining how to describe this. -ethan

Vax 11/750 power supply questions

by ian_primus＠yahoo.com

Well, thanks to the advice of a knowledgeable Lowe's employee and a sheet of 3/4" plywood, I was able to move my Vax 11/750, by myself, from the garage into the basement. Initially, when I first unloaded the Vax >from the van, I removed the power supplies to make the machine lighter. I labeled the wires with masking tape, so as to get everything back correctly. I have cleaned and reassembled the power supply section save for one connector. It's a 20 pin ribbon cable that plugs into the top of the power controller, coming >from the 2.5v PSU. This connector is not keyed, and I don't know which direction it should go - unfortunately the way the cable is folded it could really go either way. So, those of you that own a Vax 11/750 - which side should be pin 1? Also, on each power supply, there is a three position toggle switch - Lo, Norm and Hi. What is this for? Similarly, I currently have the battery backup unit removed. It's obviously going to be totally shot - the sticker indicates the batteries were last changed in 1984. This isn't needed for the machine to work, correct? I'm not talking about the Time Of Year battery, I'm talking about the box mounted on the front left side, it has a couple lead acid battery packs in it - not enough to run the computer, I would think - did this just keep the memory alive? What's the pinout of the console port? Anything special, or should a null modem cable be all I need to connect a terminal? Thanks! -Ian

Complete success, OS/8 is up and running :)

by charlesmorris＠hughes.net

I am pleased to report a complete success with my 8/A,VTserver via 11/23+,RL02,OS-8 conglomeration. I think it's the *only* time that any project (with that many places for possible screwups) has worked for me on the first try :) As I had reported earlier, I managed to get *something* written onto an RL02 pack using VTserver to talk to my 11/23+. But when I put the pack in the 8/A's RL02, for some reason it wouldn't go Ready initially. After powering down the system and drive, removing the pack, reinserting, etc. then it did light the Ready light. No weird noises either. That was a relief. I had to do a little rewiring of the console port cable since I'd previously set it up for RS232 and I wanted to use an "authentic" ASR33 for the console with 20 ma current loop. I entered a short test program to read the keyboard and echo to the printer. That worked. So far so good, the 8/A is still alive after sitting for a year or more. Then I had to dig out the manual for the 8/A to figure out how to boot it from an RL02... OK, the boot ROM takes care of the addressing, just push the "BOOT" key. Not too hard :) SO I did that - the RL02 gently clucked and the Ready light flickered, and I heard one character print on the TTY across the room. I rushed over and peered at the canary-yellow paper while holding my breath (doing so helps 30 year old hardware and software work better) and lo and behold... a single "." Yee ha! I think it's up! I hopefully typed "DIR" and hit the return - and there came the directory of my disk image, just like on SIMH except with all the noise and oily scent of a Teletype. :) :) :) -Charles

PDP-12 MAINDEC Listing?

by ohh＠drizzle.com

Hey, all: Does someone have, or know of, an online PDF of DEC's "PDP-12 Tape Control Test" (parts 1 and 2) MAINDEC manuals? I've got a PDP-12 which I've gradually been breathing the life back into, and so far it's gone very well... but then I got to the LINCtape control and drives, which are acting like they're _trying_ to do useful things but aren't, and frankly I need to learn more to figure out what the heck is going on in there. MAINDEC listings are usually pretty helpful for that. :) Thanks! -O.-

Commodore 64 question

by bmachacek＠pcisys.net

I was just able to pick up 2 Commodore 64 units. One has monitor (1701) and disk drive (1541) and works fine. The other Commodore (computer portion only) has the Power light come on, but that's about it. It does not even cause the monitor screen to be active. My question is, is there possibly a simple solution as to why the C64 is not working? I have not opened it up yet, and I'm not a real "techie", but I could do some simple internal checks if I knew what to look for. Thanks for any help anyone may be able to give me. Bill Machacek

C.Itoh Keyboard repair (was CiTOH terminals (was Re: Well, now I've gone and done it..., Dragged home more big(ish) iron...))

by jzg22＠drexel.edu

I've actually fixed one of the CIT-220+ keyboards. It's *not* a job for the faint of heart. It requires desoldering all 130-odd keys (this REQUIRES a GOOD $250 desoldering iron, lacking this I paid someone $60 to do it for me), prying each key apart with two sewing-pins, pulling the contact out and scouring out the crap in between the little contact pads using a pin, and bending the sensor-push plate/spring back into an L shape so the key gets good sensitivity. The keyboard I had required this because someone at my university had spilled something (milk perhaps?) into it and it wicked up into about half the keys and got between the metal sensor plates. (The metal sensor plates are the C.Itoh cheap alternative to any DECENT type of keyboard key mechanism such as one the IBM model M clicky keyboard used. I also strongly suspect the real DEC vt-220 and vt-330 used better technology but I've never seen a real DEC one. :( ) I'm on the lookout for a C.Itoh CIT-220+ manual or a real DEC vt-330 (plus KB) since I have the manual for a vt-330 and it looks far superior to the CIT-220+. I've also dumped all the ROMs from the CIT-220+ if anyone wants/needs a copy. (IIRC it uses an 8085 plus two GFX chips plus RAM plus EEPROM plus a bunch of logic chips in the main unit, and an 8032 or 8048 in the keyboard.) I could also scan the VT-330 manual if needed, though it will take a while. Jonathan Gevaryahu jzg22 at drexel.edu
