It was interesting to look through the archives. Sad, too. Too many of those computers are familiar!! Hey, I probably started way back with a Olivetti Underwood Programma 101 (http://www.silab.it/frox/p101). That was one of my first real experiences with a programmable computer (some would say calculator), way back in the early 70's. Somewhere after that I did some programming on a TRS-80, storing my programs on audio tape. And I wish I could use my HP-25 calculator (1976). I need to find replacement rechargeable batteries. It was amazing what one could program into that thing with only 49 steps locations! Fun stuff and RPN was interesting. Blah, blah, blah. PDP-11, DEC-System 10, Apple II in college... so on. Anyway, cleaning up through my things I've pretty much decided to break the ties and offer up a few pieces of equipment, if you know of any interested parties: ------------------------------------------------------------ SUN 3/160 CPU board (pn 501-1208) Its a 68020 @ 16.67MHz, 68881, Sun-3 MMU, 4MB, 2 MIPS, 9U VME format, B/W video, Ethernet, serial, parallel ports. This board weighs nearly 4 pounds! The site http://www.sunstuff.org/hardware/systems/sun3/sun3/3-160/ claims this is the first 68020-based Sun machine. ------------------------------------------------------------ >From the same 3/160 machine (which years ago I hauled off the 200 some pounds of chassis-- don't hate me!)... Clearpoint SNXRAM Memory Board (dated 1986) Populated with 8MB with sockets for another 4MB, if you have the necessary 144 MCM6256 (256K x 1bit) memory chips (with an extra parity bit for every eight, the numbers work out). ------------------------------------------------------------ Maxtor XT 43805 380MB SCSI Disk Full Height - Approx 6x8x3 5.5 pounds ------------------------------------------------------------ Micropolis 1325 ST506 85MB SCSI Disk Full Height - Approx 6x8x3 6 pounds Dated 1986 ------------------------------------------------------------ KIM-1 Microcomputer system (late 70s?) It's a 6502-based micro. According to http://www.6502.org/oldmicro/buildkim/kim.htm, "The KIM-1 is the first computer developed by Commodore, or better, MOS [Technologies]. MOS was an IC producing factory which Commodore took over to be sure of a constant supply of ICs.... The KIM-1 has 1152 bytes of RAM, 2048 bytes of ROM and 30 I/O-lines. Some of these lines are used to drive six 7-segment LED-displays and others are used to read the little hexadecimal keyboard." You would use audio tape for storage and use a teletype, etc. for My father built this unit up with more memory, nice power supply, etc. ------------------------------------------------------------ That's about it (I really don't consider old 386 PCs as interesting), though I do have a Casio FX-7000 graphing scientific calculator (1985). But I saw on ebay going for $6. Its not about the money, it just shows there isn't much interest in it. Thanks for your time. If you know of anyone interested in these things, let me know (I may keep the KIM-1). Scott Austin __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful.

VT50 connection

by barry.moyer＠pason.com

Greetings, I am trying to find the 20mA connection diagram for a VT50 terminal. The VT50 is very similar to the VT52, but has a terminal strip on the underside of the terminal where the 20mA connection is made. I do not know which terminal is which. If anyone has a schematic of the VT50, I would very much like a copy. Thanks.

The OTP package is identical to the ceramic/quartz package, so no problem there. The HN462532 is pin-compatible to the TMS2532 as well, so that's no problem either.

VT50 Connection

by iamvirtual＠hotmail.com

Greetings, Does anyone have information on which terminal is which for the DEC VT50 terminal? The 20mA connection is done via screw terminals on the underside of the VT50, but I do not have any information on which terminal is which.

Tandy Xenix resources - spelling fix

by kelly＠catcorner.org

I'm trying to locate a copy of the instructions for connecting a Model 2000 keyboard to a Model 6000 computer. They were included in the swap region of one of the boot disks for Xenix 3.2.something. Does anyone have a copy of this file anywhere? I think it is called m6010.tar (or something similar). Any other Tandy Xenix resouces out there? Thanks, Kelly kb2syd

What is a PVK11-G/02 ????

by bob＠jfcl.com

While pawing thru the piles of scrap boards at the local junk emporium, I came across two identical boards marked "PVK11-G/02". They have the standard double high/double wide QBUS form factor and dark brown/black module handles. The only other identification I could find printed on the boards was "Made in Australia" - no manufacturer or module number. Each board contains a 6809 (!) chip, an Intel FDC chip, a CRTC chip, a row of DRAMs, a couple of EPROMS, and some other miscellaneous logic. Now, of course, the question is "What do I have"??? A quick web search for PVK11 turned up nothing. Thanks! Bob Armstrong P.S. If you can, please cc me directly with your reply - I read this list in digest form and I can't wait a whole day to find out!!!

HP/UX 10.20

by doc＠mdrconsult.com

Hi. I've been a little slow in beginning this project, and I apologize to y'all who have been waiting patiently. My year-end slam has finally quit, and I have time to play with toys. I do have Jay West's HP/UX v10.20 media in hand, and will be imaging and testing copies this week. I have 8xx and 7xx machines available for verification; anything else is your guess. I should be able to ship the first week of January. Jay sent me a list of requests for back-up or replacement media, and I'll be contacting each of you today or tomorrow off-list. If you had asked, and don't hear from me by Tuesday, please contact me off-list. Or, if you need a replacement set of 10.20 media and didn't ask before, let me know. This is NOT a warez offer, either on Jay's part or mine. If you ask for a backup set, I will assume that you have satisfied any licensing requirements. I'll be asking for the cost of media & shipping as well - about $2.50 US per CD and about $6 per DDS tape, depending on the current price of media. There are 8 CDs and 3 4mm DDS tapes. That's based on USPS Media Mail rates. International or priority may be a little extra. Please take all further correspondence off-list, so as to keep the S/N ratio up. Happy Holidays to everybody!

VAX 11/780 anyone with some working experience out there?

by gunther＠aurora.regenstrief.org

Hiho, folks, I have been gone from the list for several months now. Seems like eternity. All my nice machines are very depressed because they get no attention. The VAX 11/780 is shivering in the garage, cold wants to run to warm itself up, but I have not enough time to let it. I am missing some critical pieces of information, to get it booted and install BSD on the RA90 disk that I have installed via UDA50. How do I make myself a boot configuration file that starts the system >from a newly installed UDA50? Of the boot configs that I have on the RX01 disk none seems to fit. And I don't know how to show the contents of these files on the terminal such that I could learn what those boot commands files do an how to enter them manually. I have no idea where to put the Unibus address and start address and all that stuff. I'm not even sure I have set the UBA50's address switches correctly. I also have installed a second RX01 drive and I was wondering how I can tell the console to show me a @DIR of that other drive? Is there a way to switch between the default drive or to give a unit number to the typical commands (such as @DIR)? My primary goal is to make copies of some of the more critical RX01 disks that I have, since some of the disks already have errors on them I don't want to loose my last console boot disk. I have asked some of these questions before but got no response, seems like noone has an 11/780 running. I would really love to get into touch with some person here who has a VAX11/780 or knows it so well to can give directions from memory. Aren't there 11/780 people here on the list? thanks, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

microcontroller geeking, a new list is born

by mcguire＠neurotica.com

(I suppose "geeking" could be considered a word. ;)) Hi folks. For some time now, Philips has had a mailing list intended for discussion of their 8051-architecture products. It was very poorly run, and there were many complaints about slowness, duplicate postings, etc, but it was a popular list nonetheless. A few days ago, they announced that they'd be moving the list to a web-based forum, and everyone screamed. Fortuitously, many weeks prior, I had set up a mailing list called "microcontrollers" on my mail server, but hadn't told anyone about it. Well, you can see where this is going...As expected, Philips' web forum was dead on arrival, and there are about fifty people (and counting) on my microcontrollers list. Mine isn't intended to be 8051-specific, but many of the first subscribers were refugees from the Philips list cutover, so much of the traffic has been 8051-related so far. I hope for it to be a general (but highly technical) forum for discussion of topics related to embedded systems development. Anyway, since I know several of you (especially John Wren, whose name I see all over the net in 8051 code repositories!) are into embedded stuff, I thought I'd drop a note to the classiccmp community and let you know of the list, and invite you to subscribe. It's microcontrollers(a)neurotica.com, and you can subscribe by pointing a browser at http://mail.neurotica.com:8080/mailman/listinfo/microcontrollers. -Dave -- Dave McGuire "She's a cheek pincher.

Brag: Scope probes

by tothwolf＠concentric.net

I *finally* managed to get probes for my Tektronix 2213 scopes late this last week. I still can't quite decide which project to tackle first ;P Unfortunately, most of the P6120 probes are missing the slip-on clip and ground leads, so I appear to have some more searching ahead of me. Only one probe has a ground lead, which has obviously been damaged and repaired by a previous owner. I suspect and hope that the ground leads and clips will be easier to find than the rest of the probe. Does anyone know offhand of a source for these parts? I don't expect Tektronix to have the parts still available, since they told me that they sold off all parts and spares for the 2213 series to GTE. The last time I talked to someone at GTE about 2213 parts, they were less than helpful, and suggested I either send them the scope for repairs (it just needs the plastic front panel) or go buy a new scope. -Toth

TRS-80 Semi-Virtual Disk Drive

by eric＠rothfus.com

Many months ago, due to my frustration trying to find real floppies to run on my TRS-80's, I began to build a virtual floppy drive for it. The idea is that I can download software from the Internet (like Ira's great site) and run it on my TRS-80 without having to make a floppy. This little box (the SVD) has an RS232 port on one side, and a TRS-80 floppy edge-card connector on the other. You download a DMK image to the SVD and the TRS-80 will boot off of it. You can use the standard TRS-80 DOS tools then to make a copy of the disk...or whatever. The box is in pretty good shape now, but still not fully functional. You can boot most OS's and even many copy-protected disks. You can't, though, write to the SVD from the TRS-80. I'm looking to make this box available for all TRS-80 nuts. I don't want to make any money off of it, but would like to use any profits (beyond cost of parts) to fund sites like Ira's or other vintage computer concerns. And the more people who will buy it, the cheaper the cost of parts. I'm guessing that I can get the cost of the box down to $50 for parts, so I'm thinking that a $75 price tag would work. Soooo, I'm looking for one or two beta testers to help me make sure that I've covered all of my bases, as well as to help move the SVD forward. I need help in testing, but also writing useful software for Linux and Windows to manage the download to the SVD. Also, I'm going to need help figuring out the copy-protection of some disks. Any volunteers out there? For more information, check out the beginnings of the SVD web-site: http://www.rothfus.com/SVD . Or just e-mail me eric(a)rothfus.com. Thanks! Eric Rothfus

Sharp MZ-80B boot disk

by avickers＠solutionengineers.com

Does anyone have a working boot disk for a Sharp MZ-80B? I went to use mine for the first time in a few months, and all of the disks are either reporting "Not a Master" or "Read Error". Since I *know* that at least 3 /should/ be bootable[1], there is clearly something awry with either the disks or drives. I'm going to try my spare set of drives tomorrow, but if that doesn't work then I'm stuck :( TIA [1] One of them I made myself, used it, and even labelled it "80B Boot Disk". And that reports "Not a master" now. Grrrr. :( -- Cheers, Ade. Be where it's at, B-Racing! http://b-racing.com
