I tried (many ages ago) to decipher the meaning/use of the dip switches at the back, but to no avail. The problem with mine was that I tried putting a later version of DOS on it, but the install pooped out, and since it ignored the floppy on bootup, I was screwed. Even tried swapping HD's etc. *NO* luck. They (I had two) were VERY picky machines. Again, let me know what you need, I'll see if I still have it laying around somewhere. Les

Stuff available

by Watzman＠ibm.net

The guy below has two IMSAI VDP-80's [parts from one of them are on E-Bay but probably won't sell, the better, complete one is not yet offered], a Newtronics ELF, and a SWTPC 6800. He just trashed a System 34 and a Burroughs L6000. If anyone wants the IMSAI, ELF or 6800, call him. You will have to buy the stuff, and pay shipping [the IMSAI is all but impossible to ship, it's best a "pick-up" job]. He's in New Orleans I think, but I'm not sure.

Maxtor XT-4380E ESDI Hard Drive settings

by edick＠idcomm.com

I've got the EXT-4000-series manual. I never owned one of the 4380's, though I tested a number. Miniscribe built a model 9380 which was quite similar, except that fewer than 10% of them would pass our tests. However, I used the 9380's for quite a while in my personal systems. There was once a military (air force, I believe) site called TheRef, which had much of this data, if you haven't the patience for me to look up the information you need. I recall there were quite a number of jumper options. If you can find me the desired configuration, I can give you the relevant jumpers and their effects. Dick ---------- > From: Zane H.

DEC stuff

by jpl15＠netcom.com

One of the sub-goodies from the recent haul is a DEC CI-750 backplane in a 5-slot frame with three modules in it, though it is marked for five. 1. L0400 2. L0101 3. L0118 * (placarded for L0100) 4. L0101 * 5. L0400 * Where the * = occupied slot. The backplane has absurdly large 5V power leads (2 ea #8) and there are four coax cables coming from slot three backplane pins, all with a side-mounted fan. That's it. Also: The Nicolet scope is a 2090-III, and although there is a small trace of some kind on the screen, it is sorta autistic. :( Now to track down docs and fix it. O Goody!! Another Project!! Cheers and Thanks for all the help... John

interesting, interesting.

by edick＠idcomm.com

I've got both beige and black drives of this type. They were used in the Maynard line of tape drives, and are really quite widely used, though almost no PC-software supports them for "real" backups. Most of the software I've seen for '95 is limited to floppy tapes and SCSI-II or later drives. That's a shame, since the GOV went to this format after they learned that one little 8 mm tape will hold what it takes a pickup truck of the old open reel 6250 bpi tapes to hold. The button and lamp locations were quite varied, since exabyte purchased the mechanisms from SONY and they could be varied a bit.

This is not one of those. I wasn't thinking of DAT, so much as the old DC300-type cartridges, which are much bigger. No matter, it's obviously neither DAT nor QIC. It sounds like an 8mm ExaByte to me. If it looks like it's 5.25" full-height, probably an 8200, maybe an 8500; if half-height, probably 8205, possibly 8505. I'd suggest you take a look at ExaByte's web pages and see if it matches one of their pictures. Try http://www.exabyte.com/suppserv/techsupp/8mm/fullhigh/ for starters. There's quite a good line drawing halfway down http://www.exabyte.com/suppserv/techsupp/8mm/fullhigh/in0111.html I've just noticed Zane mentioned camcorder tapes; they do work, but in my experience they're don't have quite the same long-term reliability. Oh, and they're a slightly different length. But they'd be OK for testing. -- Pete Peter Turnbull Dept. of Computer Science University of York

KA630 CNF?

Does anyone have any information on the KA630 CNF board? It is used both with KA630s and KA650s to configure them for coprocessor mode. Since I have never actually seen the board (which plugs into the KA630/650 directory), I'd specifically like to know what pins I need to connect to establish the processor as the first, second and third coprocessor...

Mass Teledisk group buy OPEN AGAIN!

by kyrrin＠bluefeathertech.com

The Teledisk Pro group buy is growing larger by the minute. Here's an update. Based on continued strong interest, I have decided to extend the buy to TWO copies of Teledisk Pro. I will continue (barring any objections) as the focal point for both copies. NEW DEADLINE: If you want in on the group buy, please send me a private E-mail note indicating as much. The deadline to send in your request is by Wednesday, March 3rd, at midnight (Pacific time). That should allow enough time for this bulletin to circulate on the list. UPDATED COSTS: As of Sunday, 28-Feb-99, 10:05 PST, we have 38 people interested. This brings the cost down to about $7.98 per person. This assumes a total cost of $300 for two packages plus $3 shipping (303 / 38). THIS FIGURE MAY GO DOWN if more people jump onto the bandwagon. I will post updates as they occur. As of 10:08 PST, Sunday, Feb. 28th, we have 12 (Twelve) license shares still available. Thanks again to all for your interest. This is certainly a cheap way to get a nice utility. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com Amateur Radio:(WD6EOS) E-mail: kyrrin(a)bluefeathertech.com SysOp: The Dragon's Cave (Fido 1:343/272, 253-639-9905) "Our science can only describe an object, event, or living thing in our own human terms.

Pre-Rescue scouting mission - info needed (nicolet, Decitek, and DG)

by jlwest＠tseinc.com

I decided to run over to the surplus store this morning for a closer look at the nicolet. It's in the front window so even though they're closed I could get a good look at it. I also saw some other gear I never really noticed before and would like to ask the list members for info. 1) Nicolet There are two units. The first is a model NIC-80 Data Processor. It looks identical to the unit on sellam's website. There's three rows of lights labelled AC (18 lights +1 L light), IR, and PC. Below that is a set of switches for the SR (switch register?). Top left is a "sweeps complete" display. There's two yellow buttons in the upper right labelled "data processor". Top center is a row of buttons labelled 'memory allocation', with labels off to the left and right of "start" and "size" respectively. There is a rotary knob labelled "vertical display scale", and several buttons below that labelled 'ADC resolution'. Below that is two knobs labelled Constant A and Constant B. Across the bottom are buttons for step, deposit, examine, load PC, single ins, continue, and start. Finally on the bottom right there are two buttons called Execute and Stop. Bottom right is AC power keyswitch. The second unit is a Nicolet model NIC-298 "diskette storage unit". It has two 8" floppy drives. There's a row of lights vertically on the side called read, write, and ltrack. There's an unlabelled pushbutton on the upper right, and the lower right is a power switch. Questions: The cpu definitely says model NIC-80. How does this relate to the model sellam has? More to the point, can someone tell me about operation of this unit with regards to what OS it ran, what compilers or languages, etc. Did one hook up a terminal to this or was it just console input? What made this unit different from more well known computers (ie. what was it's specialty)? Most importantly, is any real documentation around on this unit (operators guide, schematics, logic diagrams, programming info)? 2) Paper tape reader There was what appeared to be a paper tape reader. Had the leftbay/rightbay arrangement like a PDP PC04/05 with the read cells in the center. The brand name appears to be Decitek. There were two switches in the center, one was a toggle for power, the other I couldn't make out. I could easily be mistaken, but the bays looked much wider than a PC04/05, making me wonder if it took wider paper tape than I'm used to seeing. Questions: Anyone have any ideas what type of system this was compatible with, what type of interface it might use, and does anyone have docs for it? 3) Data General Mag Tape Unit There is a DG 1/2" mag tape unit there too. The unit is about 13" tall by 19" wide, with a clear blue plastic cover. The takeup reel is on the left, and it looks like it supports a very slightly smaller than normal 1/2" tape reel (but larger than the little 8" jobs). The other hub is on the right for your tape. There is a row of controls down the center sticking through the blue cover. The top is a rocker switch for power, next is a group of two lights marked 'ready' and 'write protect'. Lower is another group of two lights marked 'bot' and 'eot'. Next is a rocker switch marked 'unload' on the left and 'bot' on the right. At the very bottom is an offline/online rocker switch, and a light on the online side. Questions: There's no model on this unit I could see from the front. Anyone hazard a guess as to the model number? What type of DG was this usually used on, what interface does it use (pertec, scsi, proprietary, etc.), could it be used on other systems (till I get a DG :) ), and are there any docs available? Finally - I'm still trying to decide if I want to get all of this or some of it (depends on the prices, when I looked today none of this stuff was marked so I'll have to ask the owner). If there's any of it I decide I don't want that others here are interested in - let me know! Jay West

DECstation 316

by mark_k＠iname.com

Hi, (This isn't really on-topic. If anyone knows of a place or mailing list which covers obsolete but not classic computers, please let me know.) Today I picked up a DECstation 316. Since I'm in the UK, this European model may or may not be the same as the DECstation 316 machine which was sold in the US. This is a 386SX-based PC, presumably running at 16MHz. Useful to me because it has 4 ISA slots. The machine came with 5MB RAM and an IBM 171MB disk drive, probably added as an upgrade after purchase. This PC seems to be a rebadged Olivetti; motherboard, PSU and BIOS code say Olivetti. A label on the rear of the unit says Model:PC 651-A3 CMOS battery is almost dead, but the machine seems to work okay. Though when I first tried it the Base unit system test (part of the power-on tests) reported an error. Now it doesn't. There is no reset button on this machine, and it came with a somewhat nonstandard DEC LK250 keyboard. Things I would like to find out: - Does anyone have setup disks for this machine? I downloaded a DECstation 316 setup disk from the Digital web site, but the SPEED316.COM program on that reports "SPEED316 ONLY WORKS ON A DECstation 316." (Which is why I suspect the American machine of the same name is different.) - There is no predefined setting in the BIOS setup menu for the 171MB IBM hard disk (which is IBM-H3171-A2 P/N: 84G3902). There doesn't seem to be a way to set user-defined drive type. What can I do about this? - Does anyone have docs for this machine? There is one jumper and a 26-way IDC connector on the motherboard. What are these for? How is the drive cage supposed to be removed? I can't see any way to do this. -- Mark

If i read that right, there are 10 switches on this board. Switch 7 & 8 are defined as: 7 8 off off Arbiter on off auxiliary 1 off on auxiliary 2 on on auxiliary 3 Switch 7 is connected to pin 4 of the J2 connector (20 pin connector) Switch 8 is connected to pin 5 of the J2 connector. Don't have any of this boards, simply out of the manual. Hope it helps, emanuel

Novice prospectors guide

by yakowenk＠cs.unc.edu

Okay, I'm sure this is going to cost me, but... :-) I've made a first-attempt at a list. You can find a link to it, called "Machines to watch for", from my classiccmp web page, at this URL: http://www.cs.unc.edu/~yakowenk/classiccmp/ I'm open to suggestions on additions and deletions. My current rule of thumb (which is also open to suggestions) is that it belongs on that web page if there is sure to be someone who wants it enough to pay shipping charges for it, or otherwise arrange to take posession of it. While you're there, kindly glance at the Rescue Squad volunteer list, and let me know if your entry needs an update. BTW, how does everyone feel about advertising that? I've considered posting the URL to various related newsgroups, but am torn between the possibilities of increased donations and getting the attention of the wrong people. I'd rather not feed the e-bay "collectables" frenzy. Should I be shooting for "high profile", or just letting interested parties seek us out? Cheers, Bill.

<BTW: I also saw a Rainbow 100. Anything distinguishing it from any other <CPM/MS-DOS machine? It was a dual processor with z80 and 8088, the bus as not PC (ISA) and it allowed 768 or 825Kw of ram. It was color medium resolution when the PC was still mono. It's noteable in that it ran CP/M-80, CP/M-86 and MSdos. When Running CP/M86 or MSdos the z80 is still operational and services IO for the 8088 giveing it better performance for it's day. Allison

interesting, interesting.

by cmcmanis＠mcmanis.com

More uVaxen bits... So I finally got all my wires correct in the serial connector and now get the following dialog: KA630-A.V1.3 Performing normal system tests. 7..6..5..4..3.. Tests completed. >>> Pretty cool. However on the NetBSD/VAX faq they suggest typing 'test 50' to get the ethernet address, if I type that it just says "Failure" does the port need to be connected to a network? So it turns out the _both_ systems had the Sigma Information System ESDI controller in them (not too suprising because they came from the same source) which everyone says "Ohhh, that's a nice controller." which warms my heart, but I _need_ docs. Another reader said that you can plug into the 10 pin port on the board and do some cool stuff like low level format etc etc. But I've not tried that until I get an ESDI disk. I've done lots of searches on the net for ESDI, Q-Bus, Sigma information systems, etc but no luck! I presume they've gone Tango Uniform. But that brings up another issue, I need a mounting "sled" for the disk. Preferably two sleds, (one for each disk). Anyone have any spares? Presumably I can kludge something in a pinch (or use the bottom bay which has a "floor" anyway. I did get donated a complete set of VMS documentation (5.4) but I don't have _any_ hardware documentation, again if you have said docs perhaps we can work out some sort of trade. Given the "mini-PDP-8 surge/hunt" that appears to be going on I expect this thing to be in hot demand in 10 years :-) What was the "standard" console terminal used with these in 1985? VT100? VT220? something else? On the tape drive in the BA123, it has a plain black front with a button and two LEDs, one orange and one green. TK50? Where could I get media for it? What does it look like? Thanks for all the help everyone, this is what makes this hobby fun. --Chuck

In a message dated 99-02-27 23:18:07 EST, you write: > >I'm open to suggestions on additions and deletions. My current rule > > I think at least some Mac's are something to keep an eye out for.

There were kits to do it, but I've never seen one (or if > I have, didn't realize it). standard compact macs are rather unremarkable although i guess the 128 might be worth keeping since it was simply the first model. I think modified macs are far more interesting. for instance, i have a 128 in original box with all the ship group items. the mac was modified with a third party board to basically make it into a mac plus complete with scsi. even got an external floppy and flight sim with it! also have two mac512k models with a hyperdrive; a st225 hard drive and cooling fan installed INSIDE the mac. <!> very heavy but actually works. david

Epson CP/M Laptop

by healyzh＠aracnet.com

Quick question, what is a fair price to offer someone for a nicely decked out CP/M laptop? It's the one that has a bunch of the software on two ROMS, and IIRC has a tape recorder. It has modem, doc's and some other stuff. I'd like to offer the guy a fair price instead of getting a good deal. Zane | Zane H.

Military Humor

by cmcmanis＠mcmanis.com

As you know I got these two uVaxen that had been decomissioned from a "secure facility." (GE Nuclear Technology, and no they aren't radioactive!) One has this mystery tape drive (TK70 or perhaps an 8MM) and the other (which is the innards of a BA23 slim chassis stuck into a Sigma Information Systems expansion chassis (which looks somewhat like a BA123) has nothing but a 'hole' where the tape drive should be. Since these are configured identically in every other way I asked a friend of mine who is ex-military what his thoughts on this situation were. His response was : "Its obvious that the second system had a floppy drive. Seen it before, the rule is all disk drives are removed and crushed, tape drives can stay. The system chassis is sold as scrap." Ya gotta love that literal interpretation of the 'regs! --Chuck

Thoughts on Taking Inventory

by kstumpf＠unusual.on.ca

Cataloging your collection has many direct and indirect benefits. By all means do it. There isn't anything unique about collecting computers. It takes the same pedigree-type data as does collecting Conestoga wagons. System - sub-assemblies - related items (e.g. documentation). Please don't spend too much time on this. The Computer Museum has done it. The Smithsonian has done it. Ask them. It is covered in the Guide to Collecting Computers...field definitions, etc. are included. If in doubt, don't do this as a "community" excerise, just ask the pros and move forward. Ask you local association of sewing machine collectors, county museum, etc. The issue of compatibility between one collector's database and anothers is easily handled by remapping source to destination fields, if and when an exchange takes place. Actually cataloging your collection is a fun activity. You re-discover all sorts of items you forgot you had. Have fun. ---------------------------------------------------------------------------- ------------------------------- Kevin Stumpf * Unusual systems * www.unusual.on.ca +1.519.744.2900 * EST/EDT GMT - 5 Collector - Commercial Mainframes & Minicomputers from the 50s, 60s, & 70s and control panels and consoles.

OT: 30-pin SIMMS

by allisonp＠world.std.com

<Quite a few of my machines -- including one PC-compatible and a couple of <Sparcs -- have 30-pin 4MB SIMMs. They're fairly common. For some reason here in the Boston metrowest area 4mb 30 pin simms are scarce and don't go cheap.

Question sent to Sydex

by kyrrin＠bluefeathertech.com

I hate to see folks closed out of the Teledisk deal just because we already hit the ceiling on the first group buy. With that in mind, I have written to my contact there to find out how much extra it would be to boost the license quantity to 31 instead of 25. That should allow the six folk that got bumped out a chance to get back in. Stay tuned, fellow ClassicCmp'ers! There may yet be a solution. I can't speak for Sydex, but I can sure as heck ask 'em about this! -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com Amateur Radio:(WD6EOS) E-mail: kyrrin(a)bluefeathertech.com SysOp: The Dragon's Cave (Fido 1:343/272, 253-639-9905) "Our science can only describe an object, event, or living thing in our own human terms.

Group buy done! Thanks to all...

by kyrrin＠bluefeathertech.com

OK, we're done! All shares have now been spoken for in the first Teledisk group buy. I would like to thank all those who were interested for participating. FWIW, the last share was claimed by Dan Burrows via a phone call. I did receive about six more E-mails after the quota for this one had been reached. This tells me that there may be more interest. If anyone else wants to do this as well, please, go for it! This is a great way to buy the higher-end software tools that would be useful to us, and if Sydex did it for the group I had they can certainly do it for another one.

uVax II questions

by cmcmanis＠freegate.com

Howdy, I've taken delivery on two MicroVax II's, one is a model 630QY-A2 and the other is a 630QB-A2, the QY is basically a narrow cabinet and the QB is a wide cabinet. Both have 8MB and both have ethernet controllers. Both were stripped of drives although one still has a tape unit. (TK50? How can I tell?) Here are the questions: 1) I'd like to find a disk or two for these (they each have slots for four disks of the DU type.) what do I need to look for? Are there size limitations? 2) Can these things be booted over the network in a pinch? (one has no tape drive) 2b) Do these things have boot roms that are interactive ala ODT? Until I get disks is there anyway to verify that they work? 3) Would it make sense to combine the memory cards so that I have one 16MB VAX or should I leave it at two VAXen? 4) One has a busextender unit that goes to a non-DEC disk card labelled: "Wombat" (its a disk controller of some sort) with tag WQESD 2.8M SCD-RQD11/EC a) This is ESDI controller yes? b) It has four data connectors so four drives? c) Its in a different backplane UNIBUS perhaps? (quad height) Both machines internally appear to be in very good shape. Anyone have the "MicroVAX II 630 QB Technical Manual" ? All in all it wasn't a bad deal at $18 each. --Chuck

30-pin SIMMS

Yes . . . there are lots of 4MB simms of the 30-pin variety around. I even have a few sitting around and frequently have seen them offered for sale.

TRW encounters (nicolet)

by jlwest＠tseinc.com

Someone just mentioned nicolet which rings a bell... At a local surplus store, I've been eyeing a nicolet machine. It sure LOOKS like a computer. ISTR panel labels about registers, instruction counter, etc. Front panel has lots of blinkenlightenz. Can't recall the model number, 330 or 880 or 800 possibly comes to mind... Also can't remember but there may be a dual floppy unit with it. Just on appearances I was considering adding it to my collection - they only wanted about $15.00 for it. Looks in good shape. Can anyone give me any information on this guy about what it really is from my schetchy outline? Jay West

need X terminal host software

A bunch of X terminals were donated to the local university, but the company was unable to find most of the host software... If anyone has the host based software for these, i'd sure like to get a copy: A couple Sun SPARCclassic X units were donated. They look to my eyes as if they are a normal sun, just missing a floppy drive... Can I just install Solaris on these? A pair of terminals from "Phase X Systems". I've never heard of them. The majority of terminals are from HP. Both HP Entria Plus, and a few HP Entria II systems. I really* need the host software for these... -Lawrence LeMay lemay(a)cs.umn.edu

TRW Find

by fpp＠concentric.net

Hey, TRW was a blast this morning. I found a Sony SMC-70G computer. I looks a little like an old laptop. Does anyone have the OS for this machine? It has the video titler modification. The cool thing about the computer is the two 3.5' Drive bays. Sony developed the 3.5" disk for this computer. It was their first "micro computer." I also scored an original TRS-80 monitor that still works.

Interesting typewriter

by max82＠surfree.com

Good Morning, Today, I saw an interesting typewriter from the late '70s/early '80s called a Hermes 51 Level 4. It's an enormous 135-column daisy wheel with erasing tape. What is interesting about it is that it has an external disk drive, connected to it with an extremely thick cable. The drive is called a 'microdisk' according to the reference card. It allows storage of text. Looks like a scaled-down VHS tape rewinder. I have never seen any disk that might fit it. Does anyone know anything about this machine? This might be one of the first 'word processor' typewriters. It also has a green LED display and a light-and-mirror system to make sure the operator can easily read the paper as it is being printed. BTW: I also saw a Rainbow 100. Anything distinguishing it from any other CPM/MS-DOS machine? --Max Eskin (max82(a)surfree.com)

CORRECTION!

by kyrrin＠bluefeathertech.com

WHOA! Stop the presses! I goofed. A couple of people in the group ordered two shares in the group buy for Teledisk, so I screwed up in the previous message. We have FIVE (5) shares left. The deadline of tomorrow at 17:00 Pacific is still in effect. If we get a full 25 people in on this, the total cost with shipping will be $6.12 per person. Let me know!

Deadline: Teledisk group grab

by kyrrin＠bluefeathertech.com

Well! This is going better than I ever expected! We've got 17 people so far, counting myself, interested in chipping in for a copy of Teledisk. This has brought the per-person price down to $9.00 (assuming $150 for the program plus $3.00 shipping). We have eight slots left out of 25 originally, and it occurs to me that I should probably set a deadline. For the moment, that deadline is 17:00 Pacific Time Sunday (2-28). In other words, tomorrow by five. If you're interested in getting in on this, please let me know via private E-mail by then. Thanks to all who've signed up so far. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com Amateur Radio:(WD6EOS) E-mail: kyrrin(a)bluefeathertech.com SysOp: The Dragon's Cave (Fido 1:343/272, 253-639-9905) "Our science can only describe an object, event, or living thing in our own human terms.

Wanted: TeleVideo CP/M machine(s)

by edick＠idcomm.com

In case it's of interest to anyone, I found the (5-1/4") CP/M boot diskette for my TS806's. What's the best way to make this available to those who want it?

The IV's are 286's and are fully IBM compatible with a Phoenix based bios. They have a normal ISA bus while the III's have different shaped cards that are installed in horizontal slots.

Blinkenlights

Blinkenlights

by Jgzabol＠aol.com

To my knowledge the blinking lights go back to the UNIVAC 1, 1951. They became famous - and therefore made their way to almost any computer of that time - due to the successful 1952 US presidential election prediction on TV. It is rumoured that the TV crew wired up a few more lights than actually part of the computer. John G. Zabolitzky

Semi-OT: Question about HP 130C O-scope

by cfandt＠netsync.net

Upon the date 12:40 PM 2/26/99 -0800, Sellam Ismail said something like: > >Does anybody know when Hewlett-Packard made the Model 130C oscilloscope? >Its tube based. The serial number is 503-03353. Sometime just after the 3rd week of 1965. Rule for deciphering HP SN's in the above format as tought to me by a couple of different HP service engineers and other written sources: Take the numbers preceding the hyphen and add 6000. Result gives the first two digits as the year and the second pair is (usually) the week of production. Numbers after the hyphen are the serialized number. 1834A-xxxxxx is some unit built around 34th week of 1978, for example. Note the "A". Can't recall when, but the nation of manufacture is depicted by that alpha character. A is USA, J is Japan for example.

But with four slots, they both must be BA123 -- by the way, there should be a total of 5 slots... four horizontal on the right side (with the top one being the TK50), and one vertical on the left side for the RX50 (but you can put an RX33 there as well). What to look for? If you can get an MSCP controller (RQDX1, 2, 3), you'll need RD series disks. Max of 159 MB. If you have a third-party interface, probably much larger. I have a machine with 2GB DSSI disks, and another machine with a 770 MB ESDI disk. As for TK50, it has one large red switch on the right side and one small green LED on the left. The TK70 has a smaller switch on the right side and three LEDs. >2) Can these things be booted over the network in a pinch?

Standard were the RD51/RD52/RD53/RD54 disks. You would be lucky to find some of these. The controller is RQDX.. The biggest of these disks is the rd54, which is appr. 150MB. You can buy a SCSI controller for it (appr $1000) ESDI controllers & disks are the cheapest. (my opinion ;-)) Once again, the controller is expensive, appr. $100-200. Disks are $0-100, which is appr 70-660MB. > Are there size limitations? Budget. ;-)) > 2) Can these things be booted over the network in a pinch?

Here's their response: Greetings Joe, I have had your e-mail on my to do list for sometime but the alligators have been chasing me on other chores. Any how The tek 4051 is about 1976 vintage and it is only recently that we disposed of them to our surplus place. We had 4051, 4052 ,plotter, joystick and a printer. I still have all the manuals and microfiche for them I think. The address for our surplus unit is <sniped>. I'm already working on trying to get the manuals and to find out about their surplus disposal. Joe

Any protective device is useful in a specific situation, and protects against specific faults. Anything can be used where it's inappropriate. But that doesn't make it per se a bad thing. > 3) They are only of use if you touch the mains side of a supply.

I once said, joking, "I used to recommend steel toe-caps when moving large computers, but now I generally prefer bare feet - so you make damned well sure you don't drop it!" My view is: A protective device - any protective device - is there to get you out of trouble, not to get you into it. One should never take risks (because one knows there is protection there) that one wouldn't take without it. I disagree that the knowledge that there is an RCCB in the circuit will make me complacent. > I'd rather just work carefully, knowing any mistake I make could be > fatal. I'd rather work carefully, knowing that any mistake I make could be fatal, but also knowing that I have taken all reasonable steps to ensure that it won't. Our protection specialist at Power Tech often talks about prortection in terms of "the fence at the top of the cliff" and "the ambulance at the bottom of the cliff". When working with live high voltages, one should always try and put in place as many "fence" systems as possible - rubber gloves, isolating transformers, insulated screwdrivers, hands in pockets etc., but "ambulance" systems such as residual current devices have their place.

V35-RS232 cable?

by rcini＠msn.com

Hello, all: One of my recent acquisitions is a Roytron paper tape punch/reader. Before I actually got it, it had a v.35-to-DB25 cable on it . Now it doesn't, of course. I'm ignorant (about many things, but particularly) about v.35, so could this have been an RS-232 adapter cable? If so, how could I make one? Thanks for any info.

Amiga 1000 WCS

by mark_k＠iname.com

Hi, I thought I would type up a few paragraphs from "The Amiga System Programmer's Guide" published by Abacus, ISBN 1-55755-034-4 which relate to this. Amiga 1000 WOM -------------- The Amiga 1000 models have additional special features. Owners of these machines may be surprised that we keep talking about a Kickstart ROM, even though the Amiga 1000 loads the Kickstart from disk when it's turned on. The situation with the Amiga 1000 was the following: The hardware was done, the machines were ready to be sold, but the software in the form of the Kickstart operating system wasn't complete and still had some bugs in it. A decision was made to provide the Amiga with special RAM which would be loaded with the operating system when the computer was turned on. After this, the Amiga would prevent write accesses to this RAM, making it behave like a 256K ROM. Commodore called the WOM, or Write-Once Memory. Now the first Amigas could be delivered with the incomplete Kickstart 1.0. After the new Kickstart versions were complete (1.1 and 1.2), the Amiga owner simply had to insert new Kickstart disks. Since this WOM is naturally more expensive than a simple ROM, the Amiga 500 and 2000 are not equipped with it, since by then the final Kickstart (V1.2) was finished. The WOM raises some questions, however: Where is the program which loads Kickstart? How can Kickstart be changed, since it is RAM? Normally the Amiga 1000 operates just like the newer models, with Kickstart at $FC0000 to $FFFFFF with a mirror at $F80000. If you try to write into Kickstart, nothing happens. Write access is not possible. The boot ROM which loads Kickstart is also nowhere to be found in memory. The whole process is controlled by the reset line. After a reset, whether by turning the computer on, by pressing the Amiga, Commodore and Control keys or by executing a 68000 reset command, the memory configuration changes. Reset ----- Immediately after a reset, the boot ROM is at $F80000 (since on a reset the OVL line is set, the reset vector also comes from the boot ROM) and it is possible to write into Kickstart. It can be changed as desired! This condition holds only until you try to write something in the boot ROM range from $F80000 to $FBFFFF. Then the boot ROM is masked out again and the Kickstart memory is write-protected. In short: Reset keeps the Kickstart WOM in memory and enables the boot ROM. A write access to an address between $F80000 and $FBFFFF disables the write protection and the boot ROM. [This should read "enables the write protection and disables the boot ROM."] -- Mark

NEC APCIII

by lfb107＠psu.edu

I had similar problems with my pair of APCIII's. Frustrated, and in need of extra space, I threw them out, but I managed to save most anything that wasn't permanently attached to the case. I've got a few of the memory boards that slid in the back as well as a few parallel cards I think. I also (think) that I have a few of those NLE cards that plugged in the front. The two that i had also had another smaller (memory?) card that plugged in to a special slot at the front, an external HD connector (and a HD.... SCSI?), and a special keyboard with special buttons for graphic functions. Not surprising since they booted up with the DOS 2.11 version of AutoCAD. I couldn't, for the life of me, get them to run anything else! If anyone needs any parts let me know, I haven't got much use for them. Les lfb107(a)psu.edu

New subscriber found TI Explorer, Rainbow 100, and Pro380

by mmcfadden＠cmh.edu

I'm a new guy on this list from Kansas City. My biggest problem is my house doesn't have a basement or a garage, I keep my computer toys in the rec room under the Ping-Pong table. When the garage is built I'll have a computer spot for more stuff. I've been lurking in this group for awhile. I'm from the cardpunching/papertape reading generation of PDP8 and PDP11 types. Pre RSX-11M and RT-11. I wander into a not-for-profit computer surplus place every week. Recently I investigated the salvage room in the basement, they have lots of non PC and non Mac stuff there. Here is what I found I'm looking for more information about them. TI Explorer VME tower style machine external case dual full height 5 1/4 hard drives external case tape backup unit Might be a LISP machine TI doesn't seem to have and information about this machine on their web site. I found Usenet group ti.explorer with not much traffic. Rainbow 100 special DEC floppy DEC Pro 380 special DEC floppy and ST251 hard drive DEC PDP micro 11/23 in tower case Maybe I'll crosspost to alt.computers.pdp11.

OTOH if I make it POSIXy it will probably not work on older Un*xes. Decisions, decisions.

Need data sheet for 1101 RAM, 8008

Hi Sam and all, At 01:30 PM 2/24/99 -0800, you wrote: > >Does anyone have the data sheets for the 1101 RAM and the Intel 8008? I >need both. In the case of the 8008, an instruction set listing would also >be cool. I have both the AMD and Intel data sheets for the 1101(A). They also may be in a early (~1976) Intel data catalog. For the 8008, the best is the mcs8 microcomputer set users manual. Someone on the list just found one in the last week or 2. I probably have a "condensed" data sheet from a Intel catalog as well. The mcs8 book is about 100 pages. The instruction set would be only 4 pages or so. I might have some data >from the Canadian company that second sourced the 8008?? > >Anyone know where 1101 RAM chips are for sale (if at all?) A few years ago I searched all over the place, not only Halted, James, ACP, and any other advertisers in early Byte magagines that might still exist, but the "obsolete ic" house resellers too. Remember the ads for "8008 +8 2102's"? I only found about 3 "tubes", but may not ever use them as wire wrapping 8 chips give only 256 bytes. How many do you want? Can't you find this stuff by the barrel and data sheets by the ream there in Si valley :-)? ..Like a west coast "Poly Pac's". No I don't expect to find a Mark 8 or Scelbi, so am moving slowly to building a 8008 system. I did finally find a copy of "Microcomputer Design" by Martin by interlibrary loan :). Abebooks, etc never found it. It is loaded with 8008 stuff with things like all timing, a 9 chip 8008 system, etc. They also sold the "Mike" series of microcomputer boards, but I have never seen one except pictures in early Byte's. I also tried to find Martin or his company (In Illinois), but no luck. By the way, searching, I found a rumor that Intel was going to come out with a support chip for all the control logic for the 8008.

V35-RS232 cable?

by edick＠idcomm.com

I remember at least one contact with this sort of cabling arrangement. The v.35 normally uses a distinctive rectangular connector while most manufacturers like the cheaper 'D' connectors. The use of the 'D' connector has more to do with cable-assembly cost than anything else, and it may not be assumed that there is any implication of signal compatibility. If you intend to play with the v.35, you may want to look at the standard before risking the health of your interface hardware. I haven't looked at it in years, but IIRC, it's a differential arrangement at ECL levels or something on that order. I say this because I seem to have seen ECL logic used to generate the levels in at least one piece of equipment. I don't much regret that I don't remember the details. Now that amateur ISP's are running high-speed telecom interfaces, e.g. DS-3, from their basements, we'll undoubtedly see this one more often.

Another NEC APCIII question.

by jolminkh＠nsw.bigpond.net.au

The APC III was not IBM compatible at all in it's original form. It had a special version of DOS and the floppy drives are _Quad_ density not double density. When NEC later saw the error of their ways, they offered a special card called an SLE that when installed allowed the machine to run standard IBM compatible software. This came with another version of DOS, which I think was also specific to this machine for booting purposes. SLE stood for Software Library Extender. I think the special card had it's own 8088 cpu. APC III's were heavily marketed here in Australia and were once very easy to find. I have a number in deep storage (ie too deep to get out and look at easily). NEC also provided financial incentives for software developers here and I have come across several cases of startup companies built on these incentives, all now gone though. I think NEC learned about compatibility the hard way. To get your machine going the first question is whether you have the SLE card or not. The second question is whether you have the correct monitor. I don't think normal IBM style monitors will work.

General info on HP2000/1000 lineage..

by jlwest＠tseinc.com

Someone just asked me... >Hmm...what is the difference between the 1000 M-series and the 21MX >M-series? Paint? I thought my response might be of interest to others, so here's the scoop... The oldest systems in the "1000" series are the M series. They consisted of the 21mx 2112a, 21mx 2108a, and the 21mx 2105a. Later HP introduced the E series with the new 21mxe 2113a and 21mxe 2109a boxes. The E series did not replace the M series though. Then there was a major revision to the power supplies used in the cpu which was indicated by the B version (21mx 2112a became 21mxe 2112b, 21mxa 2108a became 21mx 2108b, 21mxe 2113a went to 21mxe 2113b, and 21mxe 2109a went to 21mxe 2109b). The 21mx 2105a stayed 21mx 2105a though. Finally there was the introduction of the F series with the 1000F 2117f and the 1000F 2111f. When the F series was introduced, all the systems became known as 1000's model such and such, with different designations. So finally there was the HP1000 F series 2117F, the HP1000 F series 2111F, the 21mxe 2113b became the 1000E 2113e, the 21mxe 2109b became the 1000E 2109e, the 21mxe 2112b became 1000M 2112m, and the 21mx 2105a finally changed to 1000M 2105a. More to the point, most of the upgrades along the way in a given branch were related to the power supply, the addition of more instructions to the instruction set (most related to better memory management), and faster memory boards. The HP 2000 systems did not designate a particular cpu. HP2000 or access, 2000a, 2000b, 2000c, 2000c', 2000e, 2000F (option 200/205 or 210/215), and the third party (NON-HP) 2000G designated a particular combination of peripherals. The hp2000 family generally used the pre-M series 2114 or 2116 cpu's. Later the 2100A and 2100S cpu's were used. Finally, even though HP still used the 2100 cpu's, many customers switched over to the 21mx 2108 and 21mx 2112 from the M series because they were slightly faster and used the new semiconductor memory. Few did setup HP2000 on the E series because they were faster enough to introduce time dependent problems in the TSB code. Generally the HP2000 designation meant the system was running TSB (Timeshare BASIC) which is my particular target of collecting since it was the first computer system I ever learned. If the same hardware was running DOS/RTE, etc. is was called an HP 1000. Hope this helps! Jay West
