First speaker announced for VCF2

by Philip.Belben＠powertech.co.uk

This is really for Sam, but I think it's worth posting to the list. > The first speaker has been confirmed for VCF2 this September. Does this mean you have firm dates yet? I'd like to book flights, time off work, etc. as soon as I can... > David Rutland was an engineer on a lesser known but very significant > computer dedicated in 1950 called the SWAC (National Bureau of Standards > Western Automatic Computer). Sounds fun! It occurs to me that I gave a small talk on the Tek 4050 series last autumn (fall). I'd like to come to the VCF, and I could probably bring my 4052 and some demo programs, and give an adapted version of the talk (either in a scheduled slot or probably more suitably on a demo stand with the machine). Finally, Sam, could you put me on the VCF mailing list, please. I tried to subscribe from the web page but we've just migrated to Lusedoze Not Tolerable and Internut Exploder, with the result that I couldn't get it to work...

HP 1611A probes

by pete＠dunnington.u-net.com

I can't remember who mentioned they had a 1611A without probes, but I checked it out in the lab today. The pod with the ZIF socket and Z80 clip does have a little "stuff" in it, but the "ordinary" microprobes are simply buffered by a little box containing a pair of 8T37 buffers and a few decoupling capacitors. This box is connected by a plain ribbon cable to a connector on the 1611A. If you need to know the connections/layout, I'm sure it would be easy to reverse-engineer. -- Pete Peter Turnbull Dept. of Computer Science University of York

Anyone have a laptop they could sell me?

by photze＠batelco.com.bh

OK.. Manney has one, but hasn't gotten back to me on it yet. So anyway, here's the deal: I'm moving this summer, and so I need to stay online. (Yes, NEED, as I'm a panel member for http://www.webhostlist.com , so I NEED to stay connected.) So anyway, what I need is a laptop, or a hand held, that has TCP/IP stacks and a graphical interface for it (so that could be a 386 or later, or a newton, Mac, or anything else...) Oh, and this is intended to be a REALLY low cost thingy... Tim D. Hotze

Tony Cole's Cray-1

by allisonp＠world.std.com

<From: Doug Yowza <yowza(a)yowza.com> <and is populated rather sparsely by chips with date codes from '80 and <'81. The chips seem to be from Fairchild primarily (the 32 F10470's loo <like they might be RAM). From Mr. Cole's "limited edition" markings, I <gather that there were 400 of these boards in his Cray-1. The Cray-1 was ECL-10k fast for it's time but low density and rams for that technology were 1 or 4k ECL bipolar. ECL had several characteristics, FAST, high power consumption and low density. The copper plate worked with a cooling system to conduct the heat away as that machine was impossible to air cool and remain that small. Why small? Conductors propagate singnals at 1nS a foot and a cable of several feet actually represented a significant delay to the overall sheme of things inside. A note: The other commonly known and slightly more recent ECL machine was the DEC VAX9000, built using ECL-100k built on custom air cooled hybrids. It also consumed power in great quantities and had special cooling considerations. <Any idea how much RAM is on the board? Can I interface the board to my <Sinclair ZX-81 to create the world's most perverse hybrid? Your could but the interface would be more than the two combined and it would eat an amazing amount of power. Allison

Is the reason those old radio/phonograph boxes are not being thrown away is that noone notice the cover and thinks it's just a pretty dresser w/o drawers :)? Also hideaway sewing machines. I do see many of them in thrift stores, though. It was a good idea, to keep technology invisible. Now, it's the other way around. Cover EVERYthing with black and beige boxes.

It powers up fine though. AFAIR the ordinary probes are just micro-hooks on single wires, which plug into a little distribution box on the end of a ribbon cable. It's quite a nice analyser, so "play with it" gets my vote. It was also quite popular, so I expect you could find manuals if you look/ask around. I'm sure we have some 1611s or 1610s in the labs. If you want me to take a look at them next week, shout. There's also a description of both models, and several examples of use, in John Lenk's book "How To Troubleshoot And Repair Microcomputers" -- which IMHO isn't a very good book, but there seem to be lots of old copies of it about, and in libraries. -- Pete Peter Turnbull Dept. of Computer Science University of York

<>The Cray-1 was ECL-10k fast for it's time but low density and rams for <>that technology were 1 or 4k ECL bipolar. ECL had several <>characteristics, FAST, high power consumption and low density. < <Excuse my ignorance, what does ECL stand for? ECL or emitter coupled logic is a form is bipolar logic that operates at low levels and is non saturating. Non saturating is where the active devices are neither fully off or fully on. Logic levels are referenced to a bias level so translation to MOS/CMOS/TTL is required. The reason for doing non-saturated logic is speed, transistors have a problem like tubes of charge storage making them harder to turn on or off and reducing speed. Generally speaking from the late '60s through the '80s ECL managed to be a factor of 5-20 times faster than the prevailing logic system(RTL, DTL, TTL) until sub-micron CMOS started to get under 10ns. The last ECL parts I looked at(years ago) were sub 1nS and could be clocked faster than 1000mhz. An example of the speed difference is 1974 the fastest TTL divide by 10 (7490) was maybe 35mhz, ECL divide by 10 was 500mhz. Allison

Yes, for certain sorts of useful. You plug the BNC T onto the back of the card, and it stops all communication on that thin-net segment. At least that's my experience with such devices. (They told me it was an Ethernet card. I didn't believe them but they insisted, so I shrugged and plugged the cable in. It took about five minutes for the folks hollering from the other lab room to find me.) If you want an MCA Ethernet card, look for one with both a BNC connector and a 15-pin D (AUI) connector. Maybe an RJ45 too but I don't recall seeing many MCA cards that had all three connectors. -Frank McConnell

Info on Teletek SBC-1

by peacock＠simconv.com

I had never seen that Toshiba chip before. The 2716 was just a guess based on the part number. I'd guess that it's 200ns RAM. Is it a 2kw chip? The Toshiba part was a regular 2016/6116 2KBx8 static RAM. Same pinout as the 2716 except for the additional WR* line. IIRC there were LP (low power CMOS) versions too, various speed grades. SDS (S.D. Sales) made an S-100 similar to the Teletek, except it could be configured as either a bus master main Z80 CPU card or a slave card. In master mode it had a memory manager, I think the full 24 bits. In slave mode the on-board 64KB of RAM could be memory mapped on a 64K boundary anywhere in the full 24-bit S-100 address space. It had a serial port (maybe 2, SIO or DART?) and a SASI port, the early predecessor of SCSI. It didn't have much in the way of software support for the slave mode, so I haven't done anything with it. My ambition is to make it a Z80 co-processor card in a Concurrent DOS system 80286 system. Jack Peacock

That's possible, but the probes themselves definitely are just wires with clips (albeit a beautifully made version).

First Comercial Software for TRS-80 in A Decade

by spc＠armigeron.com

Now this is interesting---Perseus Development Corporation developed a new version of their SurveySolutions for the TRS-80 Model I. 4K required, but as always, more is better. The date of the release is suspicious (April 1, 1998) but still, it is interesting and the source code is available. The web page is at http://www.perseus.com/trs-80/ -spc (Neat, even if it is somewhat of a joke ... )

Help in San Diego

by william＠ans.net

It seems to be all in the very preliminary stages, but time is running out... Does anyone on the list have space for a large (two-rack) Multiflow Trace machine? One has popped up, and it seems that RCS/RI has a big interest in it, but we might run out of time before we can set up a mover. A cormer of a garage might be nice for just a short time, just in case the machine's current owner needs the thing out of the San Diego place on short notice. If RCS/RI just can not pull this off, does anyone want the thing? William Donzelli william(a)ans.net

Info/docs on tube tester?

by jimw＠agora.rdrop.com

Ok, since I intend to use this thing to work on computer related gear older than 10 years old (my 083 card sorter for example), I'm proclaiming this inquiry off-limits for random flamage! B^} Does anyone out there have info (like the tube/switch charts) for an EICO Model 635 portable tube tester? I've picked up one that is in very good shape, but is otherwise useless without the charts for switch settings. -jim --- jimw(a)agora.rdrop.com The Computer Garage - http://www.rdrop.com/~jimw Computer Garage Fax - (503) 646-0174

Friday, friday friday friday, friday...

by DSEAGRAV＠toad.xkl.com

I'll be having fun friday... I get to go argue with a professional junk guy over a KS-10. The company that owns it wanted it melted down, to protect some confidential data they had on it. SO, I'm gonna say "None of your data is on the CPU, just the disk packs, so he can have the packs. There." The drives are 2 RP06es. (Yes, I know I need 3-phase. Mark says he knows where to get an RM80 or two. Is there any way around having to have 3-phase for the RPs? I was told they fail every other 10 minutes, is it even worth it?) It did run TOPS-20, but I'm chasing after ITS tapes for it. Even if I don't end up getting it, I may get the CPU cards and backpanels, and then I know someone who has the rest of a KS. Failing that, if the junk guy gets everything, I know someone else who has a whole KS, but no operating system. So, one way or another, we're gonna get a running ITS installation out of this... Am I supposed to be this nervous? I've never had to actually argue with a junk guy over a machine, in front of a buncha suits... (Division heads or something. The actual company is QUITE large... *hint* *hint*...) -------

MINDSET

by lgroebe＠insidermarketing.com

>Does anybody have a MINDSET computer? I vaguely recall these as the first >multimedia PC from the early 80's. I just found a stereo module for one, >and now I'm in search of the rest of one :-) > You can't have mine. MINDSET was about as you recall. It built in 1984 as a super-multimedia 80186-based PC-compatible (well, mostly-compatible, anyway.) For 1984, the graphics were superb and it had (IIRC) a video-in connection so you can use the computer as a character generator/paintbox. I think it was packed with a low-end cousin to the Time Arts Lumena paint program and was THE machine for graphic artists. Remember, this was a year and a half before the Amiga - which, whene IT came out, pretty much took over Mindset's market. The Mindset has a unique and quite beautiful white bi-level case design. So pretty in fact that the Museum of Modern Art put one in their design collection - the first computer placed in their collections. Much of the hardware was proprietary - weird memory modules and it also accepted plug in progrram cartridges. Mindset didn't last too long as a company. They DID build a second model, an AT-based machine in charcoal gray. I've seen it once and never read anything about it I found my original Mindset last year, complete with a couple of expansion RAM modules, the boot disks and the paint cartridge. Like I said, it's gorgeous and you can't have it. Nyah. But - I might make you a deal on the stereo module! --Larry

Freebies up for grabs!

by kyrrin＠jps.net

Time to clean out at least part of my garage, especially in light of the new arrivals. All offerings are freebies, though it would be nice if I could get -something- in trade. ;-) Please bear in mind two things. 1). I cannot ship anything other than the books. The disk and tape drives are too darn big and heavy, and would require specialized packaging in any case. 2). Dave Jenner has first pick since he E-mailed me this morning before I posted the list. I'll post an update if he wants any of the stuff. With that in mind, I have the following to offer: 1). HP 7974 9-track vertical tape drive, with all mounting hardware. 1600 BPI, Pertec interface, supplied with the hardware to convert it (if desired) to a GPIB interface. Excellent condition, powers up and loads fine, have not actually tested it with a working system. 2). (Definitely a freebie!) 83-84 vintage System Industries SMD disk drive. Spins up, makes lots of noise, don't know if it works. Comes with mounting rails. 3). Cipher 880 tape drive, dual-density (1600/3200). Condition: Who knows? Freebie. 4). Books! I've got spare copies of: DEC's 'Microsystems Handbook' for 1985 DEC's 'Introduction to Minicomputer Networks' vintage 1974 Everex 'Step 386' owner's manual DEC PDP11 'Programming Card' quick-reference, vintage July 1975 DEC DHV11 Technical Manual.

Yup, they made desktop PC-compatibles for a while. I remember a dealer in College Park, MD selling them (Software'n'Things if anyone else out there remembers them; to the best of my knowledge they aren't operating under that name anymore if at all). One of the big selling points was that they were upgradable by virtue of the passive backplane. Buy an XT-compatible now, later on you can upgrade to an AT-compatible just by swapping the CPU card for the '286 flavor. BTW Doug, is that your face I saw gazing up at me from this morning's San Jose Mercury News?

Sam Ismail <dastar(a)wco.com> wrote: > Yes they were dot matrix. I always equated line printers with dot matrix > printers. Is there a difference? When someone says Line Printer I think of something with the type on a chain (or a drum) and the ribbon in front of the paper, and then a bunch of hammers behind the paper. When the right character is in front of the right position, the printer fires the hammer for that position and pushes the paper up against the ribbon and chain/drum. But the real definition is in how much data you have to send to the printer to get it printing. If you have to give it a full line to get it going then it's a line printer. If you only have to give it a character to make it print then it isn't. -Frank McConnell

Well the F8 while known was not hobbiest fodder being aimed at embedded systems. Same can eb said for z8. The 9900 as I refer to it was not the TI99/4a(have those too) but a Technico SBC, due to a lack of TI support it was not that popular. However the TI99/4a is still quite popular. Others I've worked with 78pg11(uCOM78) were aimed at embedded applications. I might add that my time as a product engineer at NEC in the early '80s had me designing in that part as well as supporting it along with ucom4 and ucom75 4bit micros. The RCA1802 was sort of a square egg. It had popularity for a short while. People lost interest after that, partly as RCA discontinued it by the mid 80s. Also because it was slow and had a relatively poor(primitive) instruction set and a total lack of high level languages other than tinybasic. The advent of more complete systems like apple and trs80 and decreasing prices helped focus the market on two key players 6502 and z80 and it would remain that way until the 68000 and 8088(x86) would displace them.

Well, do you know if it's oiled or unoiled? I'm not sure but I think I may need the oiled. I need to ask someone. My wife says that this tape I have has the distinct smell of machine oil. It should make the punch block last longer. I was just going to order a 1/4 case from Western Numerical Control (http://www.westnc.com/paptape.html). That's 7 rolls for $33.00, in all kinds of colors. And they are close by in Grass Valley,CA. I also want to ask them about the toxicity of paper tape.

Info on Teletek SBC-1

by allisonp＠world.std.com

< Does anyone have info on a Teletek SBC-1 Z80-based single-board <computer? Copyright is 1981. It's loaded except for RAM (from what I can <see). It has a Z80 CPU, PIO, SIO, and CTC. There are a couple of blank <sockets, and a TMM2016P-2 memory chip (a 2716??). It appears to be built <a S-100 card. First off 2016 is a byte wide ram. I sounds like someone stripped the card. The SBC-1 was a complete Z80cpu(4 or 6mhz)/64kram/eprom/IO card it was designed to be used as a slave to the Systemaster cpu card. The 2016 was used to create a FIFO so that block IO coul be used to communicate with it. the only thing it lacked to be a complete S100 cp/m system on a board was disk IO. The system master card had all that and FDC as well. Allison

Logic State Analyser

by jolminkh＠nsw.bigpond.net.au

I have been rearranging my storage area and uncovered a HP 1611A Logic State Analyser fitted with a Z80 option that I picked up a few years ago. I have no idea what one would do with this. Should I cherish it? Play with it? Does one need the specific manual or are these generic and perhaps explained in standard texts? There are a number of plugin points for various types of probes, none of which I have off course. It powers up fine though.

What a haul!

by kyrrin＠jps.net

Indeed, what a haul (at least if you're into DEC stuff). Thanks to the kindly folk at St. Martin's College about 40 miles south of me, I am now the proud owner of: * A PDP-11/44 and its rack... * A Fujitsu 'Eagle' drive (and it's weight!) * A Cipher 880 front-loader tape drive... * Numerous distribution tapes for several versions of RSTS/E, including one for ver. 9.7(!)... * Various bits of documentation. Unfortunately, not a lot on RSTS itself (much of it got trashed along with the -- get this -- distribution kit for RSTS 10! Dang, I was pissed when I heard about that...) And, thanks to my friends at RE-PC, I have also acquired a pair of M4 Data model 9914 9-track SCSI tape drives. These are neat boxes! Quad density (800/1600/3200/6250), autoloading, neat front panel with alphanumeric display, etc. It's been a busy weekend. Now, if you'll pardon me, I need to go collapse and snore my brains out. ;-) -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin(a)jps.net) "Our science can only describe an object, event, or living thing in our own human terms.

Junk sale

by william＠ans.net

...mostly because I do not want to throw the stuff out/scrap it... (1) Miniscribe 8425SA drive, removed from a Mac Plus. I assume it works still, but do not quote me on that. It seemed to power up fine just a few minutes ago. The Mac was in very poor condition, so that got scrapped. (1) Kaypro 81-045-02 PeeCee. This appears to be their version of the XT (oh, joy), but unlike most clones, is a little better built. It uses no motherboard, just a passive backplane with a CPU card. This one has a 20 meg Seagate drive and a Samsung (yuck!) CGA tube. It works, and has only DOS 5.0 on it. The nice thing about this is that most of the chips are socketed! (5) Ink ribbons for the IBM 5103 printer. Still sealed, these come with a goofy plastic glove for the CE. OK, so there are probably not even five 5103s left in the world... (1) Computer Wharehouse Store catalog, Spring-Summer 1977. SWTPC! Imsai! Kim-1! $1200 floppy drives! A slice from the "good old days" of the micro. The pages are a bit yellow, but in good shape. The cover is also nice, but the previous owner scribbled his name on the top. Really, if _anyone_ wants any of this stuff, speak up and make a SILLY offer. I will ship anything but the Kaypro (I could deliver it to RCS/RI in Providence, RI, however). Trades are good for the stuff as well. Not first come first serve - I will decide "winners" in a day or two, just to give those with restricted or slow email a chance. William Donzelli Carmel, NY 10512 william(a)ans.net

The Wang patent relates to videotex terminals, exactly the stuff that British Telecom developed in the 1970s and pushed hard (as PRESTEL) in the early 80s. Prestel was organised a little like an ISP, with various "IP"s (information providers) renting space in which they creating "frames" of text and (chunky) graphics which were accessible by modem. IPs could sublet space, too, so individuals could rent just a single frame if they wanted. In 1982 PRESTEL launched a service called Micronet800, which used thousands of pages on PRESTEL servers to store microcomputer related news, software, etc, and started selling software to enable home micros to dial up and display/load/save these pages. Actually, stuff for micros had been around on PRESTEL before that, but spring 1982 was when it took off. I got my software and modem that summer. Most of the modems were simple devices built in to an acoustic coupler, fondly known as agnostic complicators. PRESTEL itself didn't make use of file extensions, but obviously some of the micro systesm that accessed it did. CP/M has always based certain actions on file types and extensions, for example. It did use menus of links, and the links between frames, could be quite arbitrary (and tangled!) just like the web. There was even a command to go back one or more frames, and there were "response" frames and a mail system and ... -- Pete Peter Turnbull Dept. of Computer Science University of York

As far as commonality of old machines goes, most airports have old machines. Public libraries do as well. The boston public library just replaced some Vaxen with Alpha machines. I couldn't get them to tell me what they did with the old stuff. In general, I would say that the amount of old machines is greater than a given reasonable estimate (ie there's always one more).

But you can't easily use both sets of registers at the same time (yes, I know we sometimes do, but it's a fiddle) and the Z80 is very much a single-accumulator type of beast. And as for IX and IY ;-) The original design of the 6502, incidentally, was that all of zero-page be treated as registers. They just happen to be external to the chip, which wasn't completely unknown elsewhere in those days. So in that sense it is possibly the most register-rich design of the era -- but the registers are hardly general-purpose, and the 6502 is also a single-accumulator design. > On the instructions RISC systems of the time and even later didn't have > the addressing modes and often had a distinct register load and store > instruction. The best example of that difference was an ADD (R1),@(r2)+. > Now compare that to the DG Nova and it is of a stark difference. If you count all the ways you can index with registers, MIPS processors have quite a few addressing modes. Not all are used very often, though. > Of all the micros in my collection, none are RISC save for the PDP-8 and > 6502 which in my mind come close. The 6502 has a certain elegance of instruction set. Quite a different philosophy to the Z80, in many ways, but I like them both. We used to say that you had to learn how to use the 6502, and when you did, the code was neat, but on a Z80, you just had to decide what you wanted an instruction to do, and then pick the one that did that. Exaggeration, of course. > I have: 1802, SC/MP, 6800, 6809, NEC D78PG11, 8748/9, 8751, 8080/8085, > z80, z180, z280, z8002, z8001, 808x, 8018x, 80286, 80386, 80486 and the > micro version of minis 6100(pdp-8), 6120(PDP-8+EMA) TI9900, PDP11(T-11, > F11, J-11).

Well, I've got all of those, and my favourite is the ARM. I've had to write MIPS assembler, and it's not great fun. -- Pete Peter Turnbull Dept. of Computer Science University of York

Well, whether I think that's sensible or not ('cos I think you ought to be able to copy a null string), if ANSI says it's undefined, then it's not a bug. I take it back.

Yes, I should perhaps have mentioned mailing to postmaster@... or abuse@... as several responsible ISPs do follow these things up. I've had two very positive responses from sysadmins, one of whom tracked a spammer who was spoofing via his system, and one from a large ISP. In both cases, the culprit lost their account.
