Hi. Are there any repositories on the net containing ancient software? For instance, tape dumps of very old UNIX versions, or Symbolics LISP system. Is anyone collecting this kind of stuff in elecronic form?

floppy controller IC (was Re: Fixing a PET?)

by edick＠idcomm.com

Without beating this dead horse too much more, I'd like to add a couple of things to the mix. (1) I've successfully formatted DSDD diskettes to 1.2MB DSHD format. I have also formatted DSHD diskettes to DSDD 40-track and 80-track formats, with varying degrees of success, depending on how carefully I tracked WHERE they had been formatted. (2) This gives rise to at least two other points which probably need to be stirred into the mix. (a) The drive in which the diskette was formatted determines what kind of drive will read/write it successfully. Formatting as DSHD must take place in a 1.2MB drive. If the lower density is to be used successfully, care must be taken to ensure that the disketted is never written in a DSDD drive, as the heads are different and the DSHD drive can't erase enough of what the DSDD drive's heads have written to be completely successful all the time. (b) WHEN the diskette was made seems to make a great deal of difference as to whether this (item #1, above) will work, i.e. whether the DSDD diskettes will format to DSHD with whatever massaging is required. Eric's comments about the emulsion placed on the media is quite correct. At some point, however, it became economically expedient to use the same emulsion in all of their (the diskette-makers') products as opposed to producing two different emulsions. That led to another period during which the bin-sorting provided a market for lots which were only slightly less "perfect" than their standards demanded, and these were then used, together with whatever completely adequate lots were necessary to meet the demand for DSDD media. The "perfect" lots of stock were punched and labeled DSHD. Clearly, a goodly portion of the time, DSDD media were sold which were completely adequate to meet DSHD requirements. Since the DYSAN folks in Luisville, CO, who were once a customer of mine, practiced this in fixed disk media, I doubt it was done any differently with floppy media . . . perhaps not, but it makes sense.

Well, only four or five kilofolk have actually voted so far. One source of skew could be that former Apple II people are probably less likely to be using a Windows-95-oriented web site than former Amiga people. Another could be that Amiga is more recent, and many voters might be too young to have had a real appreciation of Apple II. FWIW, I considered voting for PET - the system I grew up with - but went for Other instead (I really like the Tek 4050 series). Philip.

No, black is zero, brown is one, up to white which is nine. The values in the mantissa correspond then with those in the exponent. Yellow-purple-gold-gold = 4.7 ohms as someone (Pete?) has already pointed out. Grey-red-black-gold = 82 ohms Blue-red-black-gold = 62 ohms All are standard values, though 62 is less common being an E24 rather than an E12 value (i.e. only used if you're sorting resistors into 24 values per decade, not if you're sorting into 12) I would guess that 82 ohms in parallel with the resistance of the pot (which probably is wired as a potential divider) gives about 70 ohms, so the 4.7 makes it up to 75, and doesn't let you connect the (presumably sensitive) circuit on the input directly to the pin. This would imply a pot with resistance 470 or 500 ohms.

HI! Im new to the list...

by ToddJ＠symresources.com

Thanks! I think I may have some information on the Kay Pro company. A friend of my grand fathers gave me lots of computer equipment when I was about 15 years old. One of the things he gave me was a KayPro II, the one with the two floppy drives and the Hercules monochromatic screen. I told him I liked Kay Pro because of our old 8088 KayPro PC-10 I think it was.. (had an NEC-V20 processor and the usual XT stuff). He said that the owner of the company, after slowly losing profits, disbanded the company. He said that he formed a new company making CB Radios under a different name. I do not remember the name of the company though.

I'd try turning off the parity check on the unlikely chance that the parity check itself is loopy . . . other than that, you've got a _lot_ of soldering to do ;>) BTW ISTR that one of our "customers" abandoned a 6300 in lieu of having it repaired.

AT&T PC 6300 Plus Unix box

by yakowenk＠cs.unc.edu

Hey all, Yesterday I scooped an AT&T PC 6300 Unix machine on its way to the dumpster. Got it home, powered it up, and now I know why. It displays "Parity error on system board" and locks up. Actually, it displayed a bit more: Resident Diagnostics Ver 2.05P CPU (i286) PASS ROM Module PASS DMA Timer PASS DMA Control PASS Interrupts PASS Parity error on system board It seems to have 1MB of RAM, half socketed (36 81256's). So I yanked the socketed chips, and tried again. Then it did almost the same thing, but displayed a running count up to 512K before that parity message. So, what's next? I'm guessing that at least one of the socketed chips was bad, because it got farther before barfing when they were removed. But there is some other problem too, maybe in the soldered-in RAM chips, or maybe in the parity-check circuit itself. Anybody got a service manual or schematics or a big pile of clues for this thing? Cheers, Bill.

VT340 help

by cmcmanis＠freegate.com

Hello, I am trying to connect a VT340 (A version, still looking for a G2!) up as the console on my VAX3800 in the BA213. What I need to figure out are the setup controls to do this. I have an DEC MMJ-MMJ cable, which if I connect from the console port MMJ connector to the VT340 COMM1 MMJ connector, it does not seem to work. If I use the same cable and connect it to the MMJ to Female DB25 connector and plug that into the RS232 port of the 340 it does work. I've tried setup where it says "comm type" and changed it from RS-232 to DEC-423 but that didn't have the expected effect. Clues anyone? Do I need a special MMJ "null modem" type cable or something? --Chuck

Zilog Z80-MCB

by pete＠dunnington.u-net.com

While rooting around in some Z80 stuff today, I found a couple of Zilog boards, a little less than 8" square, with 62-pin edge connectors. One (the silk-screen says Z80-MCB) is obviously a processor+RAM+ROM+I/O board, and the other (the silk-screen says MDC2) some kind of RAM board. I'm looking for any other useful information. Here's what's on them: Z80-MCB: Z80, Z80-PIO, Z80-STC, AM9551, 4 empty 24-pin (ROM?) sockets, 8 x 446, a couple of small (MMI 6306) PROMs, assorted TTL, 4-way DIP switch, a 16-pin and an 8-pin socket with jumper blocks labelled "VDU", a pair of 16-pin sockets with unlabelled jumper blocks, 19.6608MHz crystal. In the top right corner there's a single-inline 7-way socket (looks like half of a 14-pin DIL socket). Two positions, J6 (8-pin) and J2 (16-pin) are empty. The MDC2 board has a Z80-PIO, 3 banks of 8 x 4116, what appear to be a couple of bipolar PROMs (one label is illegible, the other says "33-0053-16"), and assorted TTL. Both boards have a round red device that could be a voltage regulator on them. Any information gratefully received! -- Pete Peter Turnbull Dept. of Computer Science University of York

This is valuable information for me. I've got bins full of half-height 5.25" drives here, so if worse came to worse and I had to replace the 1770 with a 1772 I'm certain I could come up with a compatible drive. Interestingly, with this system when a disk is formatted it is required that the number of TPI be input. This is then stored on the disk so I might have one 5.25 DSDD disk with 40 TPI, and another with 50. The maker of the system says that it will support drives up to 255 tracks per side, "if the drives themselves ever do." Anyway, thanks as always -- Glen Goodwin 0/0

Corona Data System double floppy IBM Compatible PC (fwd)

by musicman38＠mindspring.com

I Came across a Cordata XT computer at a local thrift store today, They want $25.00 for it.. I think its to much, but it is interesting in the fact the 12inch mono monitor is built into the computer case.. Its a very clean unit with the original manuals.. I did not know that they had copied the IBM BIOS in these machines.. DO you think this machine will have any collector value ?

BTW, last night I got a program working on my CoCo 1 to read serial data through the bit-banger at 38400 baud. And that's without even doing the double-speed thing. Not bad for a < 1MHz machine. Bill.

Help with Apple II cards

by dlw＠trailingedge.com

A friend at work told me the Goodwill by our office had a bunch of stuff in so I went by there during lunch. Picked up an Apple II+ and an Apple //gs for $10.98. I already have several of these but really wanted the cards inside (and some spare parts). The //gs came with an Apple //gs Memory Expansion filled with 1 meg, a CMS SCSI II card and a Sonic Blaster. The II+ had an Apple Language card, Apple Serial Interface, Disk II Interface and a Saturn RAM Card with what looks to be 64K and space for 8 more chips. Now the questions.... I could use help getting doc and drivers for each of the following: CMS SCSI II Sonic Blaster Saturn RAM Card Info on jumper settings, drivers, etc. would receive much thanks! Any online sites for any of this? I'd really like to get that scsi card working on my //gs so I could finally use a hard disk with it. Thanks. ----- David Williams - Computer Packrat dlw(a)trailingedge.com http://www.trailingedge.com

Old main-frames & data multiplexors....

by arfonrg＠texas.net

I have come into a Teleplex box that IIRC, is used to allow time sharing onto a main-frame by several terminals... I never quite understood how this worked. I mean, how did the main-frame know to suspend the current operation and resume a previous with the use of these old multiplexors. FOND MEMORY: I remember that back in 1982, my TRS-80 Model II had a multiplexor option available to allow it to have multiple users. What can I use this thing for?

Fixing a PET?

by Philip.Belben＠pgen.com

> For the 8032, you'd need a "PETSCI" chart - Commodore didn't adhere completely > to the ASCII standard coding. I have a copy of the PETSCI codes, but they're at > home, and I'm not. If anyone needs them, e-mail me and I'll be happy to send > them to you, or post them. First time PET users beware. The character codes with ASC() and CHR$() are NOT the same as the screen codes. There are two character sets. You'll probably be debugging in lower case mode, so, in numerical order of screen code, here's the lowercase set: 0-31 (Decimal) @abcdefghijklmnopqrstuvwxyz[\]^_ where ^ is up arrow and _ is left arrow. (These correspond in PETSCII to the ASCII codes for upper case and display as upper case on early PETS.) 32-63 (exactly the same as ASCII, from space to question mark. Also exactly the same as PETSCII) 64-95 The characters you get by shifting (i.e. with the shift key) the first group. Upper case for the letters, mostly vertical and horizontal lines and a diagonal cross for the others. Shift-up arrow should be a PI symbol, but in lower case mode comes out as a chequerboard. 96-127 The characters you get by shifting the second group. On later PET keyboards, the shift key didn'd work quite as on earlier PETS, so you probably can't type some of these characters. They include vertical and horizontal lines at the boundaries of the character cell, T-junctions of the various vertical and horizontal lines in the middle, half of the characters required to do lo-res graphics (four pixels to a character cell), and histogram characters. Of particular use in PET "graphics" is code 102, a 50% grey square. (Gosh, to think I still remember the code for that. But then we always called those characters "one-oh-two's" anyway). Beware code 96 which is a shifted space, and displays as a blank. 128-255 The inverse video ("reverse field") of the characters from 0 to 127 respectively (thus including, FWIW, the rest of the characters for lo-res graphics). Tips for debugging screen memory: The addresses for the screen are 32768 to 34767 inclusive, in the usual order. Deposit with POKE A,B and examine with B=PEEK(A) or more usually PRINT PEEK(A). Note that I'm used to uppercase, but all except the first PETS use lowercase for keywords when in lowercase mode. The screen editor actually reads the screen memory. So if there is a strange character there, go up to that line and edit it (you'll soon see how the INSERT key works) to read PRINT ASC("#") and press return, and it will return the PETSCII code for the character (in this example, 35, like ASCII). This does not work for inverse video, though. Also, if the contents of the screen memory are being corrupted, you won't be able to type sensible things on the command line... Hope this helps. Philip.

I am convinced to start my KayPro Web page now. There are plenty of free Web servers out there. I have a real soft spot for the KayPro and I sense there are a few others that do also here.

Besides, you never forget your first one! :-) If anybody has any scanned photos or can scan some sales brochures etc. , please send them to DD950(a)prodigy.net . I have nothing KayPro left here except a leather cover for the 2X-84. I paid $75 for it in 1984 and used it only to take the machine home LOL. Sure seemed like a good purchase at the time! More of the history is needed and very welcome. I think Kaypro started as a test instrument company under another name and that is were the standard "portable" cases came from for the CP/M machines. ?? Also the history of MicroPo and the rise and fall of WordStar should be included here if anybody will or has written something up. I think it is also an interesting story. This will be a group effort and perhaps we can make the Web site a bit of the home page for this mailing list with pictures of the contributors etc. Regards, ??? <-- KayPro graphics, remember them? ~ Jim Rossbach "640K ought to be enough for anybody."

Likely amongst the most common was the Co-Power 88 board set which added an 8088 processor and memory to a Kaypro. The set could be used as a RAM disk (512k) or could run 'pure' MSDOS programs. It was definitely not PC compatible! - don 'History' follows: Following up on Don Maslin's reply, I've attached a message I posted last September when someone else asked a similar question about Kaypro models. If things ever calm down, I can try and write up something similar about the IBM compatible machines, ranging from the 16, 16/2, 286, 2000, 2000+, PC (many many versions, not all really made by Kaypro), PC/XL, PC-286, 386, etc. Gregory Watson gjw(a)access.digex.net Here's a rough list of the differences between the different machines. I may have missed one or two machines, I don't have my old Kaypro brochures with me (in storage), so this is all from memory. I used to work in a computer store which sold a lot of Kaypros. (I'm also limiting this to the Kaypro CP/M machines.) There were various ROM upgrades throughout this. In the beginning there was the Kaypro II (aka II'83 later). It came with 2 SS/DD full-height floppies, a 2.5 MHz Z-80, one serial port, and bundled software from Perfect Software. Introduced late 82. Next was the original Kaypro 10. It came with 1 DS/DD floppy drive, a 10 meg HD, a 4.0 MHz Z-80A, two serial ports, light pen port, rudimentary graphics, a real time clock, and software from Perfect Software and dBase II. Introduced mid-83. Then there was a Kaypro IV (aka IV'83 later). It was a II, but with DS/DD full-height floppy drives. Wordstar started being included in addition to the Perfect Software suite. Introduced in mid-83. (Same goes for the II'83, late versions included Wordstar also.) 1984 rolls around, and some changes made. The 4 (aka 4'84) is introduced. It now has two DS/DD half-height floppy drives, a Z-80A at 4.0 MHz, 2 serial ports, internal 300 baud modem, a real-time clock, rudimentary graphics. Software is from Micropro (Wordstar, Calcstar, etc.) Early 1984. The 2 (aka 2'83) is introduced. It has two SS/DD half-height floppy drives, a Z-80A at 4.0 MHz, 2 serial ports, rudimentary graphics. Software is from Micropro. Slightly later in 84. The 2X is introduced. This is closer to an old IV, or a 2 with DS/DD half-height drives. Again a Z-80A running at 4.0 MHz, 2 serial ports, rudimentary graphics, software from Micropro. Early 84. The Kaypro Robie is introduced. This is the first non-portable machine, a black desktop. This has 2 2.6 Megabyte (not a typo) floppy drives. Motherboard is basically the same as a 4, with the 300 baud modem, rough graphics, etc. (late 84?) 1985 arrives. Kaypro upgrades most of the machines to the "Universal ROM", so a boot disk for one can be used in another. The 4'84 is renamed the 2X (sometimes known as 2X MTC). Old 2X, 2'84, 4'84 are all dropped. The "New 2" is introduced. This is basically an old 2X motherboard, but with just one DS/DD floppy drive. It comes with just CP/M and Wordstar for software. (early 85?) Kaypro starts producing the II'83 again, with Perfect software as opposed to Micropro software. (early 85). The Kaypro 4X is announced. It's a Robie but in the standard portable case. I also have seen reference to the 12X, which was going to be a Kaypro 10 but with a Robie floppy drive. (I've never actually seen a 4X or a 12X. The store where I worked might have sold only one or two Robies, so it wasn't a big seller.) 1986 or so arrives. The Kaypro 1 (yes one) is introduced. It's equivalent to the old 2X, with 2 DS/DD floppies, 4.0 MHz Z-80A, 2 serial ports, etc. The floppies are vertical as opposed to horizontal. It comes with CP/M and Perfect Writer for software. At this point, Kaypro is producing just the 1, 2X MTC, 10 and Robie basically. This continued until they got out of the CP/M machines. There were also a few variations on some of these machines, such as the 4+88, which had a SWP (?) co-processor board with an 8088, 256K of memory (which could be a ramdisk under CP/M), and could run some MS/Dos software. But that's the basic list. Anyone know if I've missed anything? Gregory Watson gjw(a)access.digex.net (My parents are still holding onto our 2 II'83s, and one Kaypro 1.)

HI! Im new to the list...

by ToddJ＠symresources.com

My roommate has like 5 Timex Sinclairs, he has more classic computers than I do. Im the Kay Pro enthusiast though. I think the real reason why I became interested in KayPros was because of the 8088 that we bought. It was in the Summer of 1984. I was 6 years old. I can even specifically remember the old Kay Pro advertisement. They showed three models they were selling. We ended up buying the medium one. I also remember that they bragged about having an internal clock that memorizes the time after you shut it off. The one we got was the PC/10 I THINK.... NEC-V20 13Mhz Processor Herchulese Monochrome KayPro Monitor with CGA card. Huge case 20mb ST-225 RLL Hard Drive 2 Teac 360k 5.25" floppy drives AT Compatible keyboard 640k base memory 128k "Extra" memory that to this day I haven't figured out how to use. man that computer was awsome! I remember the very first REAL game that I bought for that system. My parents got it for me for christmass, it was StarFlight. A mid 80s space flight game. Next was Sentinel Worlds, and then I got all the old AD&D Gold Box Series games. We ended up getting a SVGA monitor shortly after Starflight. Guess what brand it was..??? LOGITECH!!! Thats right, my monitor was a Logitech, the mouse company!! It was a .49 pitch monitor, 14", and it weighed around 20 pounds or so. My parents paid like 1,500 bucks for the darn monitor.

Likewise with the Sinclair and Timex/Sinclair machines I collect -- there are many active user groups around the world who share software, as well as hardware groups who have made available devices such as disk drive interfaces, data transfer to/from IBM-type pcs, etc. But nothing for the Kaypro. Perhaps this is because the Kaypro computers weren't "hobbyist" computers -- they were designed and marketed as "business" machines. As far as I can tell there was very little third-party hardware sold for the Kaypro, and they were not exactly designed to be modified (people on the list, please correct me if I'm wrong ;>) Glen Goodwin 0/0

Latest find & haul...Kaypro 16

by Mzthompson＠aol.com

First, a big thank you to Gregory Watson, gjw(a)access.digex.net for the history lesson on Kaypro. I look forward to the PC side. A couple of years ago I did a little contract work for the school system in the next county. It was then that I visited one of the no longer used school buildings. It had been turned into a storage shed for anything the school did not know what else to do with, including the Commodores, a couple of Kaypros, a few Lasers, & a mess IBM brand PC's, just to name a few. I had all but forgotten about it, figuring no way to pry those machines loose from the school system. It turns out that they sold the building to a someone about a year ago and he is now looking for a buyer himself. I called him and he invited me over for a look around at what computers were still left. He said that if this perspective buyer wanted the entire contents that would be the end of it. If the buyer does not want the computers then I can have what I want. I think he expects me to take it all. Most of what is there is IBM brand PC's. I did not write down model numbers and all that, just looked around as he gave me the tour of the building. These IBM's are what I would call educational machines. I know the school system is big on IBM and gets the usual educational discount. Many of the machines are just dual 3 1/2" floppy machines, with some having around 60mb hard drives in place of one floppy. I did notice that the floppy drives had a 40 pin edge connector instead of the expected 34 pin. IIRC, the hard drives had the same edge connector as the floppies. Anybody out there got any insights on these? Apparently, he had a schoolyard sale and most of the Commodores are long gone, but did see some stuff. Since I am not up on that, what should I be on the lookout for in the way of goodies? On the way out, I stopped to admire one machine. He said that I could have it if I wanted it. A token I guess. We had to go to the next floor and the other end of the building to find its keyboard. Just as we got back to the machine, he commented that he never could find the cover for it. This just as I was snapping the keyboard back in place. So I now have a working Kaypro 16, complete with OS, namely DOS 2.1. I had the cover off briefly, enough to realize that it appears you have to dismantle the thing to put a board in an expansion slot. In the expansion slots are a a modem & what I assume is a secondary video board with 9 pin D female connector and RCA jack. Another card with a 25 pin D and a 9 pin D, both female, parallel and serial I assume. The fourth card has no I/O connectors, so not sure until I can get at it. One thing I would like to do to this is to put in a battery and clock chip. I have long since forgotten what was available then. Any suggestions? I won't know until mid-October if the buyer wants the computers or not. The way I figure it, they probably won't want them. Face it, if they are not a subscriber to this list, then they are not nuts enough to consider what I am consdiering, right? ;-)) Then there is the issue of where do I store 100 or so machines, at least long enough to sort it all out.

Calculator/abacus

by gp＠ecis.com

About ten or more years ago, I saw a photo of the calculator/abacus in a magazine. I called the company in Japan in hopes of buying one for myself. I was told at that time that they were not intended for sale. They were promotional items only; sometimes given as gifts to very good customers. Does anyone out there know where I might obtain one?

KayPro MC-10

by jwebste3＠bellsouth.net

Does anyone here have a KayPro MC-10, but doesn't have a Users Manual? I received a Users Manual in the mail today, along with some other stuff. It looks a little rough, with some mildew damage on the front bottom and edges, but is still quite readible. The style of writing itself is a little humorous. Definitely unlike any Users Manual that I have ever read. It contains quite a bit of technical info, as well. Despite it not being a very large manual. Jim Webster
