Ok, this is a long shot. Background: DSSI disk controller (KFQSA), two DSSI disks (RF71's), BA213 Chassis, with a three disk active control panel on the front. The control panel has three "unit number" plug in keys. One labeled "0", one labeled "1", and one blank. One RF71 is plugged into the top connector and one is plugged into the middle connector. In this configuration the "ready" lights under the UNIT1 and UNIT0 plugs light up on power up. Symptom: The controller only sees one of the two drives. The drive it sees is the one connected to the control port with plug id '0' in it. If I swap the ID plugs, the drive that gets talked to also swaps. Other Data: In the PARAMS program on these disks (or perhaps in the controller I don't know which) there are several "MSCP" variables associated with the drive. One of them is "UNITNUM" which defaults to 0. Both disks initially had unit numbers in this field of 0. I set one of them to have a UNITNUM of 1, wrote it with the WRITE command and power cycled. Rerunning PARAMS shows it now thinks it is unit 1, but it doesn't respond if it is connected to the control panel with the unit 1 plug in it. There are a few other parameters that I can set one is called "FORCEUNI" which defaults to 'true'. I've tried turning it off on one of the disks (where I set the unitnum to 1, but to no avail). Triva Challenge: One of my thoughts was that perhaps the ID plug was incorrectly "customized". The "0" plug has one center plug on top and one center plug on bottom. The "1" plug has the center and right leg in, and the center leg on the bottom. I'm wondering if it is actually another unit number. Misc Note: With the #3 and #4 switches "on" on the KFQSA, the board shows up both in the Qbus scan and in the SHOW DEV scan as disk controller 0. Any help appreciated... --Chuck

OT: Toshiba T4400C laptop questions

by cfandt＠netsync.net

Hi folks, this is not really on topic as the machine in question doesn't fit the ten year rule. But the list is a way to make first contact with this query though. Reply off-list if you please. Assuming one or more of you on the list are well-versed or even expert with the T4400C, I pose a question to a problem I would like some advice on. The machine belongs to my uncle and I'm helping him solve the problem. As you may know this is a 1992 vintage machine: 486DX, 25 MHz, 12 Mb RAM, 120 Mb hdd, VGA color LCD display plus a Toshiba Desk Station IV docking station. He installed Windows 95 and a sound card and CD-ROM drive into the Desk Sta. IV. He got the laptop second-hand and of course the manual was missing. The D.S. IV was new, fresh outta the box and has a manual. The sound card and CD-ROM is a Reveal SC400 package he scrounged from an old machine. Driver disks came with it at least. Problem is that the CD-ROM drive is not interested in working with the system. W95 does not see it. The sound card has the IDE interface meant for the Panasonic CD-ROM (which is model CR-563-B) and the CD drive is plugged into that. So, BIOS setup for setting a second IDE device does not work in this case. Looks like there's no provision in the BIOS for a second IDE (slave) device anyway. Apparently (and be aware that this is the very first time I've ever fiddled with a sound card/CD-ROM combination) the drivers for the CD-ROM are part of the sound card drivers. Well, the drivers predate the release of W95 by a couple of years and Windows 3.1 and DOS are of course the only operating systems mentioned in the installation. One of the attempts at installation seemed to let W95 know there's a CDROM and sound card but the CDROM was not accessable and the "undocked" mode caused W95 to try to fuss with the drivers, etc. to get itself running. The CDROM was correctly set to be present in "docked" mode and not present in "undocked" mode. Same for the sound card. Has anybody installed a CDROM and sound card set into their Desk Station IV and gotten it running okay under W95? Has anyone even installed W95 onto their T4400C? Results? Thanks for your experiences.

More on DEC Pro 380

by CLASSICCMP＠trailing-edge.com

> Anyway do the MFM controllers in PROs have the same hard-coded drive model >restrictions as their Qbus big brothers, like the RQDXn family? On a PRO, the MFM hard drive is ID'd by the number of heads and number of cylinders. If you look at, for example, DW.MAC on a RT-11 distribution kit, you'll find the table quite easily. You can add your own devices to the table - just keep in mind that it has to be in ascending order by heads, and then ascending order by cylinders. OK, the above is a bit of an oversimplification - if the drive in question happens to be a RD50, the drive might be damaged by the seek test that counts the number of cylinders. So RD50's are identified by a bit in the status/init register, and not by the seek test. The PRO's MFM controller only allows 3 bits for the head ID and 10 bits for the cylinder ID, so you can only use drives up to 8 heads and 1024 cylinders (aka the RD53). -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

HP "Classic" Vectra help

by cfandt＠netsync.net

Hi folks, I'm helping an ex-work colleague with an HP Vectra. It's the very first model of the Vectra (from ca. 1986) and is commonly called the "Classic Vectra". It's a 286 running at 6 MHz, 1 meg RAM . . . you know, the typical AT clone. The setup floppy disk is now missing and we need to find the setup program for the machine. About 2 years ago or so I had downloaded the Classic Vectra setup program from HP's website. I searched HP's site now and cannot find any setup files for these old machines anymore. Anybody know if the setup files are still online at HP and if so where are they? If nothing is on HP's site anymore does anybody have a copy of the setup file for the _Classic_ Vectra they could email to me? Thanks for all your help with this!

Century Data Marksman interface document.

by edick＠idcomm.com

Back in the early '80's I had this 14" 20MB Century Data Marksman drive which I soon gave away. I recently found the interface manual for it, i.e. a document which is apparently intended for one to interface the built-on controller/formatter to a Z-80. It includes some code examples, etc. Would this be of use to anyone? Dick

Cromemco 4FDC, How do you format a disk?

by edick＠idcomm.com

Some 8" drives, notably those from Shugart, had optional circuitry which you could install yourself, BTW, to do things like recover clock from the data stream, hence the SEPDAT and SEPCLK signals, and mask the sector pulses if you wanted to use hard sectored media in a soft-sectored mode, or whatever. The signal you are probably going to want is the raw data, which is common to all of the various versions. Oddly enough, the half dozen or so SIEMENS drives I have all have this logic as standard. the use of the same signal as both clock and data stems from the fact that FM data has the clock embedded in it. Hence, if you don't separate them on the drive, the controller does that by taking the signals whether they're separated or not, and feeding them to the respective circuits whose job it is to process them. They then use the signals either combined or separated, and process them as they need. These circuits are the things which got many people into the habit of referring to a drive as being either single or double density capable. Without them, they're all capable of either, since the rate at which flux reversals are written on the medium is still the same. MFM simply integrates the clock and data in a way which doesn't waste half the bandwidth on clock pulses.

My TU10 is hurting.

by jritorto＠nut.net

It used to be so nice. But the dehumidifier hose got clogged while I was gone. The room filled with mildew. I came home and rushed to save my stuff, mostly successfully. The TU10 was affected, though. I don't know for sure if the dampness was the cause, but I'm guessing it was. Here are the symptoms: under rt11 5.00, it won't init a tape. used to do this w/ no problem. rt returns "output error on mt0:" The tape spins and tries to init, but after going back and forth a number of times, it gives up. So the mechanism and control logic seems fine. I've tried different tapes and cleaned and degaussed the head. No change. Jiggled all the cards in the controller and device section to 'assure' a good connection. Nothing. I even tried using an old copy of ROLLIN, just to see if it'd do a backup, but it moved the reels and instantly gave a FATAL DEVICE ERROR on MT0. Unfortunately, my xxdp pack is thrashed (moldy), so until I can replace it, I'm stuck with trial and error here... help if you can, please!

Cromemco 4FDC, How do you format a disk?

by bill＠chipware.com

The subject pretty much says it all... I can't seem to figure out how to initialize a disk with this controller. I'm sure you do it via the WRITE TRACK command, but I don't follow what it is that you are supposed to OUT to the DATA REGISTER. Also, just for laughs and because I have hundreds of disks (thanks AOL!), I want to hook up a 3 1/2" floppy to it. This should be OK, shouldn't it? How many tracks and sectors-per-track? What interleave? Finally, I gathered up all of the CP/M 2.2 stuff I could find on the web... I've been looking through all of the docs... They all seem to make the assumption that you already have a CP/M system disk, on the correct media, properly formatted and all you need to do is get your system specific BIOS onto it. Looking at the BIOS level implementation, it seems that CP/M doesn't have a native format command? Thanks, Bill Sudbrink

Low level formatting DSSI disks with KQSFA?

by mbg＠world.std.com

>Anyone know the procedure? Can it be done? Do I need some special >diagnostic program (do vaxes run XXDP?) I forget if they can be formatted, but I do know that they can be erased and scanned... but you need to have something which speaks DU Protocol (DUP)... if you have a uVaxII or uVaxIII, you have what you need... You have to use one of the maintenance commands from the uVax console... One of the commands of the form SET HOST/MAINT/UQSSP/SERVER n where n is the number of the UQSSP port. Once the DUP starts up, it will prompt for a command or filename... type DIRECT and it will give you a listing of what is available. Some drives have different numbers of programs available, so try what looks obvious. BTW - the DUP protocol is essentially a protocol which causes the VAX and the KFQSA to exchange packets of text. You type something, it is packetized and sent to the KFQSA where it is passed to code running in the disk. The output of that code is passed back to the VAX in a packet. I don't know of anything else which speaks it (unless there is something on the user test TK50 under MDM). And it is a proprietary protocol, so I can't explain the specifics.

Cromemco 4FDC, How do you format a disk?

<> The 1771 is a single density only controller and not suitable for use wit <> 3.5" disks. You want a board with a 765 (compupro) or 1793 CCS and a raf < <Are you claiming that you can't format/use a 3.5" disk at single density? <Now, I can't think of a machine that did, but equally I can't think of a <reason why you can't. The floppy drive really doesn't care how you One, at the lower data rates the 1771 is running below the 3.5" floppies 720khz rates and the 1771 does not do the faster one! So to be compatable with a 3.5" drive you need to run the 1771 at the 8" single density rate to get a something approximating 720k disk. At that rate your running at 250Kbits/Sec wich is the bottom data date for 3.5" floppies. Personally that is is a lot of effort as you will have to rewrite the bios for the different tracks/sectors and also allow for sides. OH, forgot that most SD controllers did only one side. If your going to the effort why not use a good DD controller and run the dsik up to the 1.44-1.6MB range? At that amount of storage CP/M feels like your using a slow hard disk. I know this from putting 3.5" floppies on my Vt180s, Ampro, Kaypro, SB180, CCS and compupro systems. All use 1793 or 765 DD controllers. Allison

BA213, uVAX 3900, and KQSFA questions

by cmcmanis＠freegate.com

Ok, finally got a moment to put together some bits in my uVAX 3900 in the BA213 cabinet. I've got it built as follows (from right to left) KA655 32MB Memory 32MB Memory DECSQA (ethernet) KFQSA (DSSI) TQK70 (TK70 contoller) Then wide open space. :-) [meta question, presumably DEC had fill plates for the empty slots?] In the top part I've got a TK70, and two RF71's. The RF71's are connected to the KFQSA via an internal cable that daisy chains first the rightmost drive then the left drive and then ends at a bulkhead that has a mini connector (looks like SCSI2). On that connector I've got a DSSI terminator plugged in. When I boot the cpu does all of its diagnostics but it doesn't "see" the KFQSA. One of the drives blinks fault the other rattles around a bit and then blinks ready. Some questions: The front panel has the disk lights bulkhead configured for three disks. I connected the small connector of the rightmost disk to disk one connector and the left disk to the second drive connector. Is that correct? When I type SHOW DEV to the uvax prompt it show the ethernet and tape but NOT the KFQSA. Is that normal if the disks are not inited? When I type Megan's command "SET HOST/MAINT/QSSP/SERVER 0" to access the internal controller on the KFQSA I get >>>SET HOST/MAINT/UQSSP/SERVER 0 ?28 UNK SW Any ideas anyone? --Chuck

Cromemco 4FDC, How do you format a disk?

by edick＠idcomm.com

You'll need to spend a bit of time studying out how the controller you're using handles the drive select or even a cable select if it has separate selection on the 34 and 50-conductor cables, and whatever it does to manipulate the clock extraction circuits to derive the appropriate clock for whatever data rate you're wanting. BE CAREFUL! Some controllers switch the clock frequency as they make whatever assumptions they may make about the nature of what's on each cable. In order to drive 3.5" diskettes, you need to fool the controller and software into believing it's talking to a drive on the 50-pin cable. Though the 8" drives have only 77 tracks, they have the 360 rpm spin rate and most other parameters in common with the little teensy drives. If your controller switched the clock assuming its top data rate will be 250 kbps, you may have problems.

DEC Professional 380

by healyzh＠aracnet.com

Yes! I finally scored a Pro380, well, actually it's a "VAX Console", but hey, same thing right? Question, does it use the same monitor as the DECmate and Rainbow's? I know there was a colour and a mono version of the monitor, is do they both work on the same computer, or do you have to match specific computers to specific monitors? Having asked that, I should be getting the monitor in the next few days from the person I just got the computer from. I know it's got a RD52 in it, and I suspect it's a working system as it is off a system that is currently being deinstalled (which is why I don't have the monitor yet). Yes, it's safe to assume I'm fairly clueless about Pro's. This is so COOL!!!! Zane OK, I'm calmed down now....

It's clear from the above that you can't do a tape write, but it's not clear where the problem is because a write involves both the read and write channels. What happens when you try to read a known good tape? If you know the problem is reading, it's straightforward to hook a scope up to the read channel and trace the head signals through at least to the formatter. If you know the problem is writing, you trace through from the formatter to the write heads. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

Old Olympus printer needs new home

by dastar＠ncal.verio.com

Here's a guy wanting to get rid of an old Olympus printer. Please reply to him. Reply-to: lberke(a)bellatlantic.net Sellam Alternate e-mail: dastar(a)siconic.com ------------------------------------------------------------------------------ Don't rub the lamp if you don't want the genie to come out. Coming this October 2-3: Vintage Computer Festival 3.0! See http://www.vintage.org/vcf for details! [Last web site update: 05/25/99] ---------- Forwarded message ---------- Date: Mon, 12 Jul 1999 09:56:34 -0400 From: Lee Berkebile <lberke(a)bellatlantic.net> Subject: donations It was an early printer, based on a typewriter mechanism (Olympus, I believe). I used it with a Commodore 64 (this should help date it) soon after the Commodore came out. The nine pin dot-matrix printers available then gave poor print quality. The Daisy wheel printers gave typewriter quality, albeit slowly, and had all the features such as subscript, superscript, bolt, underline, etc. The Commodore printers of that era did not have descenders for the lower case g, j, p, and y letters, for instance. I believe the price was $240.00 Cheers, Lee

Conway's "Game of Life" ... when invented?

-----Original Message----- From: KENNETH S HALEY <haleyk(a)okstate.edu> > >As a finale, self-replicating CA structures were invented by a guy in a >LANL working group (see 'artifical life') with an Apple. > Wrong! Christopher Langton (who organised the first Artificial Life Conference, September, 1987, Los Alamos National Laboratory) invented a simple example of a self-replicating structure for a cellular automata system based not too loosely upon the work of E. F. Codd. The reference is a book entitled Celluar Automata. The work of von Neumann is collected in a volume by Arthur Burks entitled Essays on Cellular Automata. Codd's CA has eight states and the neighborhood function of von Neumann. It has the curious characteristic of providing a model of brain cell function, i.e. neurons. William R. Buckley

Long-Distance Moving and Storage

Consider a company that specializes in moving computer equipment. They use "air ride" trailers that are more shock absorbent and their drivers are trained in computer friendly driving. I have been able to ship equipment in racks with just a blanket thrown over it with these specialty movers. Request an "air ride trailer" anyway. Use padding and cardboard to protect front panels. Park all hard drives, check their mounting bolts and check their slide mounting bolts to the frame. It is especially important to check the rack mounting bolts and screws. We lost 30% of an Amdahl drive array when the drives shook loose of the frames due to a rough stretch of Interstate I-5. It tripped their shockwatches. This is where an "air ride " trailer would have been valuable. Two complete layers of large bubble wrap is sufficient for heavy plastic printers and terminals (i.e., TI 810s, Wyse 50s, etc.) when contained in a box. If you have a lot to ship consider buying a large roll of bubble wrap at a commercial packing supplier. I get a 48 inch wide roll of large bubble (about 5 feet in diameter) for $80 from a supplier of discount cardboard box supplier. I like the stuff that is perforated every 12 inches if they have it in stock. Put a stick through the core and hang it from the ceiling so it unrolls easy. If you just rent space in a trailer sit down with a pad of graph paper to sketch out your layout in advance. Measure all the racks, boxes and pieces so you can fit them on the floor of the trailer. Some people like to cut out the pieces to make the easier to rearrange. Make note of top-heavy racks. These will be need to be lashed to the side walls of the trailer. After rolling in any equipment on wheels, lower the adjustable levelers so they won't roll. Protect with cardboard and tie each to the walls. If you use commercial movers they will do all of this. You do need to tell them about top-heavy racks. Consider packing the workstation monitors upside down in a box with large bubble. Cut a collar of bubble wrap to fill the space between the base and the monitor in any case. If you have several consider packing them in a cardboard Gaylord. This is a heavy cardboard box the size of a pallet, approximately 40" X 42" X 4' to 6' height. These are usually available from the same place I get bubble wrap. Put the box on a pallet before you pack it. Strap it to the pallet after you fill it. Remember Force = Mass X Acceleration. Also that Mass wants to travel in a straight line. Both of these are germane to packing a trailer. Good luck Paxton

Conway's "Game of Life" ... when invented?

by hhacker＠home.com

Now, cellular automata is my field. John von Neumann invented cellular automata at the suggestion of Stanislav Ulam, when the two worked at the Los Alamos National Laboratories in the 1940's. See von Neumann's work, The Theory of Self-Reproducing Automata, and the book by Arthur Burks, Cellular Automata. John Horton Conway invented life as an alternative example of von Neumann's work. There is also the cellular automata invented by E. F. Codd. The game of life was first described in the October 1970 issue of Scientific American. William R.

HP2100 memory problems and facit 4070 punch

by jlwest＠tseinc.com

Thanks to all who responded to the memory parity problems I was having on the 2100. I have gotten further...I'll share the info in case anyone else runs across this... basically all memory needs to be cleared. Note - this applies to the 2100's, not the 21MX's. Take off the front panel cover by removing the 4 allen head screws. Turn on the power, and select the M register. Press clear display, then hit memory display and clear display again (ie. set location 0 to 0) <grin>. On the lower left of the front panel board is a switch, move it right. Then move the switch on the upper right of the front panel board right too. Finally hit the INC M switch. This clears all 17 bits of all memory present in the system (16 data + 1 parity bit). Move the two switches back left and button her up. I believe the two switches are instruction lock and step lock IIRC. Suddenly the memory test is working well now. I'm swapping 8k boards one at a time to locate any bad ones. Back on the 4070 punch..... The standard HP punch (I forget the model, 2785 or something comes to mind) used an 8 bit duplex register board. If the guy I got this facit 4070 from really did use it on the HP at least, I wonder if it was hooked up to the 8bit duplex board like the normal HP 2748B paper tape reader was. Just a thought.... Thanks for all the help folks! Jay West

Not quite a classic, but...

by Philip.Belben＠powertech.co.uk

Car boot sale (flea market) yesterday. Someone wanted 80 pounds (about $125 US) for an Amstrad NC200 laptop. Manual is copyright 1992, CE mark on case dated 1993, so not quite a classic, but... Rather a nice machine - screen looked like about 80*8 (I didn't count) or 80*10 characters, all pixels addressable. Processor probably Z80 (*) - the manual wasn't very informative, and the owner wouldn't let me dismantle it :-( Has a strange custom spreadsheet, a word processor, a VT52 emulator and a port of BBC BASIC in ROM, and 128K bytes of RAM. Since the owner wouldn't take offers, I didn't buy it - L80 is far too high; I would have offered L50 absolute max - can anybody tell me what I've missed, and what sort of market price it has (I'd guess thrift store $10, Ebay $100 but I don't know) (Owner's daughter pointed out that another potential purchaser or two had looked at it and said it was v. cheap. Since they lost interest as soon as I told them it wasn't PC compatible, I didn't read too much into that. Heck, you can get a 386 laptop for L80 without difficulty...) Philip. (*) I finally found that the port of BBC BASIC includes a Z80 assembler instead of the usual 6502. Thus my guess as to CPU. BASIC ran "FOR A=1 TO 10000:NEXT" in 6.75 seconds as measured on the internal clock, so I'd guess at 4 MHz, but that's just guesswork... ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

Top 150 Collectible Microcomputers

by kaikal＠MICROSOFT.com

Aye, I had the NeXT Cube and some other workstations on the list, as well a whole list of proto-PDAs like the Newton MessagePad, Casio Zoomer, NCR 3125 PenPad, AT&T Eo, GridPad, but nuked 'em all since they're too new. I love the NeXT Cube as much as the next techno freak, but once we start down that road, suddenly we've got BeBoxes, 20th Anniversary Macintoshes, Cassiopeia WinCE handhelds, Monorail PCs, the iMac, and pretty soon we're buying "collectible" stuff new off the shelf at CompUSA. About the newest thing on the list is the PS/2 80, and I had to think about that for a while. I left it on, because it represents IBM's fall as the dominant force in microcomputing.

I will post full details when I have got it all out of the car and found out exactly what it all is. I am also going to have to dive into my SunOS manuals to find out how to boot to single user mode and reset the root password as it has been forgotten by its prevoius owner. Regards Pete

New Acquisitions! (HP2000) -> now facit 4070 punch...

by jlwest＠tseinc.com

Tony Duell wrote... >These pull out towards the back of the punch - on later models >there's a little metal rod that retains them. Loosen the screw that >clamps that and slide it up out of the way. I must have a later model, mine has the metal rod you mentioned... However, the rest seems different from what you described. When I remove the baseplate, the first board visible does have some stuff on it, but certainly not a uart. This first board is almost (within 1/2 inch) as long as the board underneath it. This first board is virtually empty, except there was one row of 13 small transistors top to bottom, then a row of approximately 3 resistors and 1 diode for each transistor. Then there's a fair amount of traces taking the signals to the edge connector. It would appear that the sole purpose of the back half of this board is to bring two test points to the rear of the unit (6v and gnd). The board underneath this appears to be the main logic board you referred to, as there are a number of power transistors on the board. As a point of reference, there are also a set of hardwired jumpers, labeled 1 through 8 on the board too. Next to this is a set of small transistors marked off as 1 through 9. Then there is a metal plate (3 screws remove the top half of it) revealing a final small PCA, obviously power related (theres a few 7 watt resistors, and what appears to be some yellow coils). The guy I got this punch from swears it hooked up to a standard rs232 serial port, but at this point I'm skeptical. Is any further info available? Thanks in advance! Jay West

Sun 2/120 questions.

by fluke＠mcs.net

I have been looking for quite a while to try and find a framebuffer for my sun 2/120. I have everything I need for a working system, including monitor,kb,mouse,cpu,etc etc etc but I have _no_ framebuffer! I even have OS tapes. The card cage and system works, as I used it with a vt100 terminal for a while.. I couldn't get my tapes to install, though, and I am not sure why. Anybody have any advise? Also, is there a good place to go for pinouts and such? I was looking around for some pinouts, but found a hard time of finding only the pinouts for a VGA connector. Is there a place that just has pinouts for things that might be useful to classic people? ie- MCA bus, crazy kb connectors on old workstations, etc etc? Thanks, Greg Linder fluke(a)mcs.net

Conway's "Game of Life" ... when invented?

by ss＠allegro.com

Hi, I was wondering if anyone knows when John Conway invented "life". The best I've found on the web is "1960s". But...I just saw a movie, "Ocean's Eleven" (starring Frank Sinatra and the rest of the Rat Pack) ... and I'd swear that the start of the credits looks a lot like a run of life (i.e., several generations of display in the cellular automata game) at the beginning, which then segues into pseudo-Vegas neon signs. The movie is credited as being in 1960. thanks, Stan Sieler sieler(a)allegro.com

First I want to say that Western Numerical Control sells copies of the technical manual for the Facit 4070. The cost is $25 and if you order, ask for the free mylar sample and they will send you about 50 feet of 1" mylar tape. The Facit 4070 punches mylar just fine. OK now, the manual calls the first or bottom board the "matching board". And says "This board can be supplied without components, to be used by the customer for his own interface electronics". This board in my 4070 was originally blank but was then hand wired with one 74LS04 and one 74LS00 to invert the 8 data bits, and one 74LS123 to provide the right length pulse for the punch start signal. I also have a HP 9884A (which is the same thing) that has a HP PCB with transistors in this first slot. > The board underneath this appears to be the main logic board you referred > to, as there are a number of power transistors on the board.

These punches come standard with a parallel interface, but they make RS-232 interface and a "Multi Interface" board which is a parallel,RS-232,and current loop interface. This multi interface has a toggle switch to select the interface and a DB-25S on the board for RS-232 and current loop operation. (For parallel operation the DB-25 on the rear of the punch is used). This multi interface also has two 8 switch, one 5 switch, and one 4 switch dip-switches on the board. So without seeing your board I would bet that it is a parallel board. Here is the information that Tony sent me before I ordered my manual (hopefully it will save him from typing it all in again :) > Here's the jumper board info - it's very simple. > First find pin A1 on the option card connector.

IMSAI Progress

by bill＠chipware.com

Well, I gave up on the MIO for a while. Tony's explanation, while good, was making my head spin! Also, I don't have any 26 pin card edge connectors. So I started looking at the Cromemco 4FDC documentation and, lo-and-behold, it has a serial port. The documentation on the serial port is clear and simple, and I now have toggled in a short program to initialize it and echo characters (also, put them on the front panel lights). According to the docs, the EPROM on this board contains a monitor which operates through the serial port, but, and it is quite emphatic about this, it is Z80 code. Is anybody out there using one of these? With an 8080A? Maybe could send me an alternate monitor to burn on an EPROM? Thanks, Bill Sudbrink

Corvus Concept, Varian 620/L

by fmc＠reanimators.org

Al Kossow has scanned a couple of manuals that I've had sitting around for a while and put 'em up on the net. He's not on the list but says it's OK to tell y'all. He'd also like to know about Varian 620/L software and documentation. If you have some or know something about it, send him e-mail at aek(a)spies.com. Feel free to cc: me, I'm interested too but not real knowledgeable. OK, on to the Corvus manuals. Note each file is a 9MB PDF and these may not be the ideal manuals for you to learn about the Corvus Concept. Read the following descriptions before downloading. The Service Manual is just what it says it is; if you have a broken Concept or want to know what to do about one this manual will probably be of interest. The Hardware Reference includes the theory of operation document for the Concept hardware, a section on how write code to talk to the Omninet interface, and a section on the Corvus hard disk interface which addresses both the electrical signals on the interface and the communication between the computer and hard disk. Reading the latter made me think that it should be possible to talk to a Corvus hard disk (at least at a disk-block level) with a sufficiently bi-directional IBM PC flavor parallel port or similar interface, a (passive) cable, and some software that I haven't got around to writing yet. http://www.spies.com/aek/Corvus/ConceptHWRef.pdf - Corvus Concept Hardware Reference manual http://www.spies.com/aek/Corvus/ConceptServiceMan.pdf - Corvus Concept Service Manual Thanks for doing the work of scanning may be directed to aek(a)spies.com. Flames about PDF format can be sent to me. I won't really care either but sufficiently good flames might move me to ask Al whether he has raw files that I can do something with in my copious free time (ha ha). -Frank McConnell

FS: Nice 486SX machines

by rhblake＠biigfoot.com

Sorry for the sales ad people but I need to move these quick... I just picked up a dozen Dell 425s/NP machines last night in place of payment for work done for someone. They all work great and look like new. Each has 4 mb ram and most have 213mb hard drives, some 120mb. A cdrom can be installed as there is a closed off 5.25" baywhich can be used by opening the cut out in the front bezel. They run a 486SX-25 processor and are in a very durable low profile steel desktop case. Each has built in serial, parallel, mouse, keyboard and video ports. You use a PS/2 style keyboard or an adapter, and use either the PS/2 style mouse port or one of the serial ports. They each have 3 spare ISA slots as well and a 3.5" floppy and IDE hard drive interface. All onboard jumpers are plainly marked and onboard video can be disabled to accomodate a separate video card. BIOS is easy to get into as well and very easy to work with. RAM is 72 pin SIMMs. Beige in color, good condition. Most had DOS and Windows 3.11 and many had OS/2 originally. Win95 will function well on them with added RAM. These would make excellent linux boxes as well, or even a low buck machine for those odd tasks or for the kids. Each has been tested and loaded with MSDOS boot only. Add your own operating system, monitor, keyboard and mouse for a sweet little machine. They've been tested with both mono and color VGA monitors. I can add one of the 2S/2P cards I have if you desire additional ports, for $3.00 more. Will include setup docs. I traded these for a $300 debt long overdue so $300 * 12 is $25 each. That's what I need from each plus the shipping via USPS (insured). They weigh roughly 22 lbs each for shipping. Drop me a line at RHBLAKE(a)BIGFOOT.COM if interested. if I'm able to get my video capture back in use soon I can send out clips of one of them. I'm located in central KY (zip 42726) and if someone is nearby and would like to pick one up they can contact me to arrange a daytime meeting. These need to go soon so contact me quick so I can hold one for you. I prefer to get payment by money order but personal checks are fine if you don't mind wating an additional 8-10 days for it to clear.

Epson I and II+ available

by pwhiting＠imt.net

Hi folks, Am new to this list, hope I post this msg correctly. I have two working Epson computers, a I (an 8088) and a II+ (a 286). Both have hard drives, I believe a 20 and a 40, respectively. I have original OS disks, manuals, etc. They are solidly built, classics (I guess they meet that definition!) and I got them cuz I thought Epson printers were so well-built (still have an MX80, btw, maybe someone wants that). Turns out the Epson computers were not 100% IBM compatible, they had some proprietary features as in the keyboard, floppy controllers I think, and maybe a couple of other items. I cut my computer teeth on these guys, and miss the days when you could get under the hood of a computer and fix 'em yourself! Anyway, I've been advised to chuck 'em in the alley but I really hate to do that. Would like to find 'em a good home. Are they worth anything to anyone, and if so how much? I will trust the fairness of the group here in establishing their worth... maybe they're not worth that much, but they'd be a pain to pack. I don't have the original cartons :( but maybe someone would pay what it would cost me to dump 'em (gently) on the counter at the local MailBox and say to the guy "pack 'em up". TIA! ...

hp2100 memory problems

by jlwest＠tseinc.com

Anyone on the list familiar with the memory subsystem on HP 2100s? I'm getting parity errors on both 2100s. Each one has 32k, so my idea was to switch to an 8k configuration, swapping till I isolate which boards are bad. The CE goldbook talks about this a small amount, but even with that info all eight 8K boards appear bad. I find this hard to believe, so I must be doing something wrong. Can anyone help??? Jay West

OS/2 (Was: New Finds)

by allisonp＠world.std.com

<complete (Templates, for example). I have also briefly seen OS/2 3.0 Warp, <which ran faster, IIRC, but again, I didn't develop a liking for it. I have that kit and I can't use it on the 286 laptop, requires 386 minimum. It does run real well on one of my 386/25s, screams on a 486dx2/66. What I've found though is some of the drivers are slow and if you have some oddball hardware it's not a good match. I've seen a PS/2m50z running 2.0 and I was impressed. Then again I've seen dos run poorly on machines due to configuration errors. Allison

Small SCSI drives

by peter.pachla＠vectrex.freeserve.co.uk

Hi, >....The problem with apple/Mac drives is that the are still very >much in use and generally the owners want too much because >they are Apple branded/certifed.... Actually....does anyone here in the UK have an 80Mb Apple branded hard drive they'd be willing to part with (it's a Quantum LPS80 with Apple ROM) or could anyone anywhere possibly send me a ROM image of the ROM from said drive; I've got a drive with a bad ROM which I desperately need to fix and/or replace (preferably fix as I need to retrieve the data from it)?

Hi all, Jackpot system for the week. Hyundai Super-lt3, a 286 laptop. Neighbor put it out for garbage, works, with adaptor and the battery is even good. I consider this at the hairy edge of classic but it's a useful tool. I plan to replace the 21mb drive with a spare 80mb and use it hard. Oh for those neighsayers. I took out the company W3.1 floppy set and installed it, it doesn't scream as it's only a 10mhz 1mb system but I did it for laughs. Later I'll install Minix, CCPM, OS2, DR-dos anything but MSdos.

RK05J blower motor

by Jgzabol＠aol.com

Hi all, the blower motor in one of my RK05J disk drives (DEC PDP-11/34a system) burned out. I would like to obtain (buy/trade/anything) a replacement, either the motor or the entire blower assembly. Of course, if you have a RK05J where the motor could be salvaged from I would be happy to do the removel. Part numbers are DIGITAL BCO8R-01 UA Rev. M ECO 007 MFG.N.S. 733 Motor is KOOLTRONIC, Inc., No. 7162-0407 115 V 60 Hz 0.47 A U.L. File No. E 40513 Type U62 3000 rpm By the way, Kooltronic still exists but they do not have any stock left. In the shops you find lots of 1560 rpm motors, but no 3000 rpm. Thanks and regards John G. Zabolitzky Munich, Germany

I have 3.0, so that's what I'd try. The comment was anything but MS! However, I have run 4.0 OS/2warp on a p166 and it was pretty nice compared to W95. 2.0 would run poorly on Pentium as it's 16bit code and the pent is far from optimum in that mode. What I need to find for the Hyundai is there are 8 switches near the handle in the front... what do they do??? Allison

Windows/286

by rigdonj＠intellistar.net

Hi all, I found an original MS disk today labled Windows/286. It says that it contains Setup, Build and Displays 1. Does anyone know how many disks are supposed to be in this set? I was thinking of installing it on one of my old 286 systems just out of curiousity. Joe

RK05J blower motor

by Jgzabol＠aol.com

In einer eMail vom 7/23/99 1:56:25PM, schreiben Sie: << Could a local electric shop rebuild the motor for you? (Assuming a replacement is not in prospect) >> Of course that would be possible; however, that would be quite some expense since it involves a lot of manual labour, very expensive here in Germany !

First laptop?

by kaikal＠MICROSOFT.com

No. Byte Magazine first used the term "laptop" in reference to a production computer, after viewing the Epson HX-20 at a trade show in November 1981. The Model 100 came out in March 1983. Kai -----Original Message----- From: Max Eskin [mailto:max82@surfree.com] Sent: Tuesday, July 20, 1999 2:54 PM To: Discussion re-collecting of classic computers Subject: First laptop? Hi, I walked into Radio Shack today, and was delighted to see a row of posters on their wall with photos of old Radio Shack stores and equipment from the beginning of the chain to now. They mentioned that the TRS Model 100 was 'the first laptop in the industry'. Is this even marginally true? --Max Eskin (max82(a)surfree.com) http://scivault.hypermart.net: Ignorance is Impotence - Knowledge is Power
