UK/US power question

I'm pretty sure it can; the Compact uses a standard SMPSU in the disk box. There should be a 110/220 link on it. To open it up, you need to remove the front and rear trims. These are clipped into the side trims, but also have two (or three?) bumps on top and bottom edges which fit into small slots in the metal case. They're a bit fiddly, and often very stiff the first time, but they will come off without tools. Then you can remove the side trims, and if I remember correctly, there are a few obvious screws to remove before sliding the cover off. (Caveat: it's a long time since I've taken a Compact or an Acorn Filestore (same case) apart). -- Pete Peter Turnbull Dept. of Computer Science University of York

RG-71/U 90 Ohm Cables.... can anyone use 'em

by badger＠vbe.com

I came upon a supply of brand new Consolidated RG-71/U 90 Ohm coaxial jumper cables. They are 3 feet long and are terminated with a Kings PL-259 on one end and a Kings BNC on the other. I don't know what they were intended for .... although the connectors are very common RF items 90 Ohm impedance isn't. Someone told me that RG-71/U might have been used in the computer industry....... I don't know ???... but they are high quality factory cables. I'm not sure but I think they were used with some type of scientific equipment or sensor ???? If you can use these cables let me know ...... reimburse my shipping costs and you can have them. Mailing should be between $3.20 and $6.00......... Regards, Mike Melland

forklift rental in San Jose, CA?

by eric＠brouhaha.com

[more about the computer rescue mentioned in my last message] Unloading in Milpitas, CA will be even more fun since we don't have a loading dock at this end, the ramp isn't wide enough, and the truck companies won't rent trucks with lift gates for one-way moves. Apparently they don't think that people move large heavy awkward items one-way. It's a shame since I know from personal experience that a VAX-11/780 (or 785) will just fit on the lift gate of Budget's 15-foot trucks. (For safety, I recommend having at least three people to stabilize a VAX while a fourth operates the lift. However, in an amazing display of sheer stupidity, a friend and I unloaded a 785 by ourselves.) Has anyone had experience with forklift rental? I did a web search and turned up *zero* hits. From a different rescue operation, it is known that a forklift is a excellent way to move a PDP-11/60, which is almost as big as the 11/780. However, that time there was a lumber yard across the street that was willing to send the forklift and operator over to help; this time there's no lumber yard nearby. :-( Eric

Vax 8350 offered to me -- worth getting it?

by claudew＠sprint.ca

Hi I am being offered this computer. I think it's 3 large modules. I have large collection of micros from the 197x-198x but, I know almost nothing about vax'es... I would we prepared not to keep it or donate/trade parts or whole...I have no real space to keep this for a long time... It would be in Montreal, Canada. Is it worth the hassle of picking it up? What should I check for? My wish list : TRS80 III (I and IV too), NExT, older CP/M systems... Thanks Claude

THose interrupts and IO lines offere more than most minimal z80 systems without Zilog peripherals. The 8085 is often forgotten despite being a decent chip. Allison

No question the z80 has many more bits than 6502, 8080, 8085, 9900, and a pot load more.

I tried to limit it to the programmer accessable. If we add temp registers and whole knows what in the state or microcode portion of the machine it surely would grow more.

Lisa WEIRD!

by jlewczyk＠his.com

If the connections are only to the video board, then the "magic switch" is simply a way of adjusting the "height" of the display. In one position, the video is full height, with the standard Lisa rectangular pixels. In the other position, the video is vertically squashed to produce square pixels. Its pretty low-tech. The device probably has adjustable resistors somewhere on a small circuit board in order to tweak the display for each position of the switch. If you pull it all off, you have just the standard Lisa (full height) display. I think that it would be pretty straight forward to homebrew one of them. The real Apple-supplied modification was more involved and produced a full height, square pixel display. It included a transformer which modified the screen height, a new video rom (which controlled generation of video sync signals and the Lisa serial #), and new boot roms. John jlewczyk(a)his.com -----Original Message----- From: owner-classiccmp(a)classiccmp.org [mailto:owner-classiccmp@classiccmp.org]On Behalf Of Marion Bates Sent: Saturday, November 04, 2000 2:52 PM To: classiccmp(a)classiccmp.org Subject: Lisa WEIRD! Okay, so after my post I went and fiddled some more and lo and behold, after a few more power cycles it booted perfectly from the hard disk. It's running MacWorks Plus some version or other with Mac System 6.0.3. The hard disk sounds like it's full of sand (yikes) but otherwise it seems to be fine. :) This is where it gets bizarre. I took the top lid off to get at the video adjustment pots and managed to eliminate the vertical jumping etc. so the screen is pretty much back to normal operation. But inside, on that same board just below those adjustments, I saw two or three sets of jumper wires, the kind with the little spring-loaded L-clip at the end. One end of one of them is clipped to R1 right near the top of the board, and I can't see where the other end is without really gutting the machine, which I'm not ready to do just yet. Another jumper has one end connected to a leg of R21 and then it disappears inside. It also looks like there's a small alligator clip connected to a heat sink and leading off somewhere else. So it looks like someone went in there and jumped some connections, then closed it all back up and left it that way. I'm afraid to touch them. Maybe this is related to the mystery switch (see my earlier post). Strange... ?

PT SOL-20 question

I've been watching the Altair, IMSAI, and SOL-20 listings on eBay lately, more out of curiosity to see what they go for than anything else, but noticed something odd about a SOL-20 image. In the listing, the picture definately showed a SOL-20, but instead of the normal front panel showing 'SOL Terminal Computer' in both white and yellow lettering, this machine has a single 'Interactive Computer' in whie stylized 'computer font' across the front. Is this an OEM version of the SOL-20 sold under another name?

A while back I said I passed on an cmos ASIC project that was going to use 8088 (actually 80186 core) as a embedded app. the client insisted on it and planned to inegrate 32-64k of rom and at least 4-16k of ram with it.

VAX 4000/60

by azog＠azog.org

I've been lurking here for about a month now. A friend of mine told me there were a lot of DECheads here, so I signed up. I've been puttering around with big iron for about a few years, but I don't have anything left (had two VAX 730's and several PDP-11's - an 11/34, 11/73 and what I think was either an 11/04 or an 11/03... I'm sorta regretting getting rid of any of them... I'd like to get back into hacking Unibuss stuff someday) Anyways, I recently got a VAXstation 4000/60 from e-bay, for what I considered to be a nice price. Works fine. Had VMS 5.5-2 on it, but I got the hobbyist license and VAX/VMS 7.2 CD from montagar (good deal!). It only has 24mb of RAM - 8mb built in, and four 4mb chips, leaving two slots open. Unfortunately, the best I can do on that setup would be 32mb RAM. I know the machine can do 104mb (96mb in chips, I guess that would be six 16mb chips), but I'm not sure of the type of memory used. It also has two RZ25's, which are a bit tight. What limitations do I have on drives that can be installed? I'm not using the frame buffer. My intention even before I received it was to run a serial console. But I think it might be fun to run a graphical display. Have no idea what type of frame buffer is installed, except that it has an odd sub-D connector with three mini-BNCs inside. What's the specs on the monitor that can be connected? Can I get an an adapter cable to connect it to my PC monitor?

Heathkit EC-1 For Sale to Highest Offer

by badger＠vbe.com

Now that I have an idea of the EC-1's general value from members of the list ...so I don't get screwed selling it blind ...and, as I learned from my faux pas in stating I was selling it on eBay... In order to allow members of this forum to have a chance to purchase this computer prior to my listing it on eBay, here it is. If you are interested here are my terms: 1. Offers are accepted via email effective 2000 hrs UTC, November 3, 2000 until 2000 hrs UTC November 6, 2000 ONLY 2. Minimum Offer accepted is $350 3. Buyer pays all actual shipping costs, insurance and any import duty or customs fees. EC-1 ships on receipt of payment 4. Payment to be by certified funds (cashier's check or money order) and must be received within seven days of end of offer. Payment may also be made with a credit card via PayPal. 5. EC-1 is sold "as-is" with no warrantee or guarantee I will try to assay the general condition of the computer as accurately as possible. There are no dents or dings. There are a some small scratches. The mesh case is dark green in color. The pots were stiff and two were frozen but were able to be freed up using Caig Labs DeOxit and seem to work fine. There are chips out of the plastic screw slots on two of the the balance pots but they still work fine and it's not noticeable unless you specifically look at them. The tubes test ok and the chassis appears clean and in good order. I can find no obvious faults electrically. The computer powers up.... both filament and high voltage. The meter works and I was able to check the B+ voltage (right on the money) and balance all the amplifiers at all 3 working voltages (100,10 and 1 VDC). It comes with the original operators manual and three of the resistor/capacitor plug ins. No other plug ins, leads or cables are included. All the knobs and switches are original and they are in very good condition. I have tested the unit only this far and all seems well but it is sold "AS-IS" with no warrantee due to it's age and my inability to test it's operation further. A picture is available at http://www.vbe.com/~badger/bc/ec1.jpg or http://www.vbe.com/~badger/bc/ec1a.jpg If you need more general information, have something you want me to check or e-mail pictures let me know.

PDP-10 Emulator (was: Re: MULTICS Installation, Halifax)

by xds_sigma7＠hotmail.com

LOL, I essential gave away a complete, operational 2065 (KL-10) complete with manuals, software, 5 or 6 RP06's, and a pair of TU78's, simply because I could no longer afford to go rescue it after making expensive car repairs... So I shudder to think what that would bring.. And I want to make the promise that I will never, ever, be caught dead selling any minis or mainframes or whatnot on any auction site... Sure, I've sold some stuff to DEC resellers, but that was just 3rd party crud.. I'm not saying that I don't think its right for these machines to have a value, I'm only saying I personally would not feel right about selling things I have mostly accquired for free..

Cool... too bad, the only DECtape I had was rented; wish I'd bought it. Among other things, I had Richard Greenblatt's Makhak chess program. Is that still around? IIRC, it played about a 1600 point game, perfect for lousy-chess-player me. -dq

IBM 5160 saved from the trash.

by ncherry＠home.net

I recently found an IBM 5160 in the trash, it has no keyboard (but I have a spare). It's almost all original! It has 256K on the motherboard, an AST Clock/Serial/384K RAM board (I think it has a game port too). It has the 6845 full length Black & White/Parallel board, a Hayes full length 1200B modem card (Z8 processor), a Xebec hard drive interface card, an internal/external floppy card, the 360K floppy and a Seagate ST-412 (Noisy). I'll try to recover the data off the hard disk, I have no idea how I'm going to deal with the drive issue (I may have an 8 bit IDE card and small drive). I am really tempted to put CP/M-86 on here. I've never used that OS before and it would be more interesting than PC-DOS 2.0/2.11. I haven't completed a full check out of the machine yet but I have enough spare boards that I should be able to bring this up. I even have a spare IBM PC (not XT) MB w/cassette interface. :-) -- Linux Home Automation Neil Cherry ncherry(a)home.net http://members.home.net/ncherry (Text only) http://meltingpot.fortunecity.com/lightsey/52 (Graphics) http://linuxha.sourceforge.net/ (SourceForge)

DECsystem 5400 and NetBSD?????

by mcguire＠neurotica.com

On November 3, Matt Thomas wrote: > Almost anything can be coerced into running NetBSD. :) Ok, Matt. :) You've just uttered the perfect lead-in for what I've been planning to say here for a few days now: I've got a big beefy pmax machine available...a DECsystem 5810. It's in a chassis very similar (identical?) to that of a VAX 6000, with similar power requirements. It has one processor (third digit in the model number) and a LOT (I don't remember how much exactly) of RAM. It has a large XMI backplane plus a BI bus. There are two or three XMI-based SDI controllers, in addition to a plain old KDB50 in the BI bus. There are no disks with the system, but if you're starving for SDI disks I can throw in a couple of RA90s. It has a TK70 also. There are other goodies in the BI bus...if anyone *really* wants me to I'll go out to the warehouse and look, but that will take some effort. The machine is very clean and in near perfect physical and cosmetic condition. It ran fine about two years ago when it was last powered up. I paid real $$$ for it 2.5 years ago, but I'm willing to let it go for a case of Dr. Pepper to a person who can convince me that they won't scrap it. It will need to be picked up in Laurel, Maryland, which is right off of Route 95 between Washington DC and Baltimore. There is a forklift available at the pickup point, and I can get a few guys together to help heft it, but after that you're on your own. This is a really cool machine and I'd like to see it go to a good home. I realize it's big and a pain to move, but I do hope that anyone so inclined will give it some thought. -Dave McGuire

ZCPR & Other CP/M Extensions (Was: RE: CP/M 1.3 memory requirement)

I haven't found anything >that can read my SB-180 disks so I hven't been able to transfer the ZCPR to >anything else yet. I think it would be cool to get it running on a PC! SB180 disks should read using standard PC FDC and the correct driver. The problem is they did some weird sector layout but, the SB180 does use a PC compatable controller (765 core). I can read my SB180 disks on the Kaypro using 96tpi drives. It may be the disks you have are 48 tpi or they can be 96tpi (user option). I've migrated mine to 3.5" drives. > I stuck out. I looked through my ZCPR docs and book but none of them >tell what the differences are between ZCPR3 and ZCPR 2.2. "ZCPR, The >Manual" only gives the differences between ZCPR3 and CP/M 2.2. I don't >know anything about the earlier versions of ZCPR so I guess I'm no help. No real difference for the most part. ZCPR3 improved the install process and added a few utilities. Allison

You would not be ending up with GE hardware. While the Level 68 (6180) system Honeywell built carried over some features from the GE635/645, it had quite a bit of new stuff that wasn't in the 645. For example, rings were implemented in software in the GE645 version of Multics. The Honeywell 6180 put them in hardware. Additionally, this is not a Honeywell 6180 being offered, but a DPS-8/M. If you contact Mr. Renshaw, he may be able to answer the question about a set of coldstart tapes for the machine. If not, Perigon Systems (the "last" Multics) would be able to supply them. The trick is, for how much? regards, -dq

IBM P70

by jhellige＠earthlink.net

I found a rather interesting machine today at a local thrift store. It is an IBM PS/2 Model P70. Normally I don't pick up IBM PC's or clones, but this has the following: - luggable, roughly the size of a large breifcase - 80386 running at 20mhz - red gas-plasma VGA display - one 16-bit MCA and one 32-bit MCA expansion slot - 120meg IBM ESDI hard disk - 4meg RAM - parallel, serial, PS/2 mouse, VGA, and unknown HDI-30 connector on the rear. Unfortunately, it lacks it's keyboard, which isn't connected by way of the standard PS/2 connector. It won't boot past the memory test due to the lack of keyboard and it gives me POST error codes of 301, 162 and 163 on the screen, as well as beeps twice. Does anyone know what the square 30pin connector on the rear panel is? It reminds me of the HDI-30 SCSI connector found on some Powerbooks. I picked it up because I thought a portable Microchannel machine with a gas-plasma VGA screen was pretty interesting. Not to mention it's the only MCA machine I have.
