I've got a hard drive with a 6-inch SCSI cable, and at lengths that short, you really don't need the extra ground lines, unless you'be in a *really* noisy RF environment. OTOH, if you really need to run long SCSI cables, having the extra ground lines isn't really enough; in that sense, single-ended SCSI is technically inferior to differential SCSI. > > More conventionally, the serial ports follow normal pinouts, even > > though they're electrically RS-422 instead of RS-232C. > > Eh?

And no, I can't think of one... Well, I'd posit that Apple _set_ standards instead of following them. For example, Apple's use of a DB-25 for a SCSI port and the pinout they chose has been copied widely throughout the industry. More conventionally, the serial ports follow normal pinouts, even though they're electrically RS-422 instead of RS-232C. In 1984, there wasn't any kind of a standard in place yet for a mouse interface. And as someone else pointed out, Mac power cords fit just about any computer device from the PC era forwards. regards, -dq

Combination of procrastination and lack of resources has put this one in danger. PDP 11/45 system with a terminal or two is in danger of ending up on the scrap in a very few days. I've been trying to find a way to get up there to get it, but it is just not working out.

68k TinyBasic

by ryan＠inc.net

Anyone have some experience with TinyBasic for the 68000? I've made a few mods to make it run on my homebrew 68k system, but it gets quirky doing a list, sometimes causes address errors, etc., Trying to debug it, but I would say the internals are "highly optimized", and therefore somewhat hard to follow. I know it's a long shot, TIA, Ryan

COSMAC VIP Instruction Manual

by vcf＠siconic.com

I have an extra copy of the COSMAC 1802 Instruction Manual (120 pages) that I ran accidentally. I run copies of manuals for folks at $0.25 per page which covers my time and expenses. Since the folks who I ran the other copies for paid for them, it would be unfair to just offer it up for shipping, so if anyone wants it at $30 (postage included) please let me know. I'm embarrassed that it has to cost so much but again it does cover expenses and my time. It took me about 4 hours to run 8 copies of various manuals the other night...way more time than it should have but the copier I was using is finnicky and doesn't do automatic 11x17 double-sided copies, so it was a slightly manual process. Kinko's would charge $0.07 per page, and a double-sided 11x17 page counts as 4 pages, equals $0.21 per page just in copying costs :( Anyway, if you are interested, please contact me directly at <sellam(a)vintage.org>.

Wanted: MITS/Pertec Extended BASIC

by r_beaudry＠hotmail.com

Hello all, In the continuing saga of my Icom Attache, I have it up and running, no magic smoke, and I have received the manual from Steve Shepard (THANKS!). However, with only 512 bytes of EPROM on the Turnkey board (TURMON and MBL 1702s), it's a bit limited :-) The monitor can display memory, alter memory, or jump to a memory location. The MBL can load from a cassette tape. That's about it... The manual did note that there are a few versions of BASIC that this machine can run. 8K BASIC is the smallest, and also the most limited. More interesting to me is what they referred to as "Extended BASIC" either on cassette tape, or on a PROM board. Further up the line is DEBI (Disk Extended Basic by Icom), but I have no spare floppy controller for this machine. If anyone has Intel HEX files for the Extended BASIC EPROMs, or Extended BASIC on cassette tape, please let me know... Thanks!! Rich B. (I subscribe only to the digest, so I may not reply immediately...)

How old is this PDP8?

by kees.stravers＠iae.nl

Hi, Usually I don't announce in this list my new additions to my collection. Recently I even have become somewhat ashamed about them, because my house is getting increasingly harder to live in. Sometimes it is more like a childerns maze made out of old computers than a home, and only visitors with a technical background can understand why it looks the way it does. But now something arrived that I have to tell you about, and ask a question too. A good friend works at a big research lab of the PTT here in The Netherlands. They were vacating a building and he could have the computers that were left behind. It was the same adventure as Megan's, including the very large truck filled with classic goodies. My friend gave most of them to me. They were a PDP-11/84 with a lot of drives and a PDP-8/e. He also put a PDP-8 in my garage. It seems incredible, but I think this PDP-8 is an original one from the first series from the 1960's. I put up a few pictures at http://home.iae.nl/users/pb0aia/cm/garage2.html Could you experts look at them and verify that this really is a very old PDP8? I ask because I just can't believe it is one. It is hard to believe for me that the Dutch PTT has kept this machine in its offices all these years. The sticker with the service contract number is still on it. I don't ask because I want to sell it. It is still my friend's property and he will collect it from my place as soon as he has made room for it, and he will be getting it working again too I think, because he was programming it himself a long time ago.

Too late for the Sords

by ekman＠lysator.liu.se

Sorry to have worked up a lot of commotion for nothing, but earlier today I received the news that we are too late to save the Sords. They were thrown in a container and dumped God-knows-where a little more than a week ago. Let us hope that they were at least disassembled and recycled. The guy I spoke with says that there may be a few tape drives left (not Sord CR-5, but other models for Sord's business range). If anyone is interested, contact Claes Borlid directly at +46 (0)31 887613. It grieves my heart that this treasure could not be saved. It is small comfort that even if we had acted faster we would not have been in time. /Fredrik PS. The company did save a few working machines of various models so that they can set up their own museum in the future. Thus, not quite everything was lost forever.

Computer Device Teleterm 1030 info?

by elf＠ucsd.edu

Hello Ernest! Well... I'm just a bit excited here, because I've been looking for one of these for LONG time -- and just the fact that a fellow enthusiast has one is good news to me! ;-) Anyhow -- I'm so gaga over this little machine because it was my first. Yep. Starting around 1979, almost every weekend, I used one of these marvels - when my father would bring it home from work (I'd look forward to Friday's so much -- waiting for the terminal to show up (oh yes, and my father of course ;-) and if there was no terminal for me when dad rolled in at 5pm, well, it was a long 7 days until the following Friday -- sigh.) I used to go through rolls and rolls of thermal paper - I would guess an average of 6-10 rolls from Friday evening when I started pounding on the keys until Sunday night when I had to give it up (actually, I usually sneaked in some more time Monday morning, real early before school.) I would dial up to a local TIP and then connect to machines back at MIT (in the days of I.T.S. and their "tourist" accounts.) I had logins at MIT-AI, DM, MC, and ML. Dialogs would ensue, real time chatting (connect with ^_c I think? I know I had the hardest time figuring out how to produce a control-underscore for some reason), mailing list reading (what were they call again? HUMAN-NETS and SF-LOVERS I believe (?)) This was all real novel for me at the time: I don't want to date myself here (why not Eric? ...) but to a grade school kid - I was doing some unique stuff compared to my peers. I developed quite a group of fellow "tourist" friends, and some MIT student friends -- although the notion of having tourists was not all that popular with some administrators at the LCS. I even visited the lab at MIT a couple times (relatives live in Boston area) and recd the full tour of "545 Tech Square, the 9th floor" (I know - big wow - but for me, at the time, having _never_ used a CRT terminal, it was a chance to experience things such as emacs without having to work your way around it using a thermal paper printout (ugh). I ramble - back to the Teleterm: I don't know what the connectors on the back are - IIRC - I never had to use them. I just jammed the phone headset as hard as I could into the acoustic coupler and kept the ambient noise down. Those inverted-toilet-bowl-plunger designs (er, I mean acoustic-coupler) frustrated me on many occasions. And I have to ask: Any more of these machines available? I've had no luck in finding these at all! :( Finally - I had thought the unit was actually called "Miniterm" as opposed to "Teleterm" -- but since you actually have the unit ... I do have a picture of the Miniterm I had used -- see it at http://home.san.rr.com/instep/miniterm.jpg (BTW - This is my first post to this list - I have been a silent reader for quite some time - and have the usual first-time-poster-jitters. I also want to thank Marvin(a)rain.org for pointing this list out to me!)

It's got two 720k 3.5" floppies and complete and in very good cosmetic condition. Does not include a keyboard but it takes about any PS/2 connector'd keyboard you can find. I have $7.00 into it. Anyone want one of these for the $7.00 plus UPS or USPS shipping? Remember now that it's ont he heavy side, about 35-45 lbs possibly. Drop me a direct note if interested.

HP documentation woes

by jate＠uwasa.fi

(This is just griping so feel free to press 'D') Every once in a while I fire up google and try to find out something about HP 9000/500 series. Anyway, today I made two discoveries: 1.) HP doesn't know about HP-UX 5 (or 4) http://www.software.hp.com/HPUX-RDMP/history/slide1.htm but there's HP-UX FOCUS newsletter(s) http://www.software.hp.com/HPUX-RDMP/related/focus/hpfocus.htm sadly not about the FOCUS cpu. 2.) HP journal has completely disappeared. www.hp.com/hpj now returns a 404. Gargh, even Digital, the notorious site "re-organizer" *and* even after being bought by Compaq still has Digital Technical Journal in html, pdf, ps and text. The links maybe broken but at least you can still *get* them. Sorry, I'm just whining as it's too difficult to get any detailed cpu or instruction set manuals for the FOCUS chip and I'm just jealous at all the PDP/VAX-people:) -- jht

Computer Rescue needed in Portland, OR

by healyzh＠aracnet.com

I'd posted something about this a couple months ago I believe. The time has come for me to dump a bunch of my collection, actually that time is long past. I've decided to concentrate on the portion of the Hobby that I'm most interested in. Namely PDP-11 and VMS systems. I managed to get rid of a bunch of stuff yesterday, but still am needing to get rid of more. I've got a bunch of junk that just needs rescued, I've got other stuff I'm looking for some money for or some Sun or DEC stuff that I can use (fairly modern in other words). These items are marked with a '$'. Now for the bad news, some of this stuff it needs to go by Saturday the 2nd or it goes to the scrapper (and I work evenings).

Actually, you can _just_ get away with plugging it into a 15 amp circuit if you unscrew the L5-30P and replace it with a 5-15. I used to do that all the time... I was told by one person that the L5-30 was for mechanical reasons, not for electrical (L5-20 is kind of wimpy). ---Rob

VMS BBS network

by ajp166＠bellatlantic.net

-----Original Message----- From: THETechnoid(a)home.com <THETechnoid(a)home.com> >>How would user accounts be handled? Also most importantly is anyone >>seriously interested in this? There are two ways to do this, one is proxies to specific applications. The other is a generic guest account that has limited permissions. Of course you can do an account for every one that wants to use it. Basically anything you do under unix or NT is reasonable for VMS and striaght forward. >I'm so green I don't know how to create other users at this point.

80186 and now AMY chip

by ajp166＠bellatlantic.net

From: Eric J. Korpela <korpela(a)ellie.ssl.berkeley.edu> >I for one would be interested in seeing whatever references to 8080 internals >this kind of stuff comes from. The bulk of what I have doesn't give any >internal details. I'd alway assumed that there was some sort of >synchronization of writeback to the accumulator (or other destination register) >or the update of the flags that ate up the extra cycle. On the 8080 you have cycles that are 3-6 clocks long and total cycles(clocks). IE: to fetch a 3byte operand like a LXI SP,1234 requires 3 CYCLES and and an extra clock to put it in the SP. Still thats only 10 clocks. an an ADD REG is only one cycle and 4 clocks, the address and staus out eat two clocks with status availabile on the midpoint of the second clock. The remaining clocks, T3 is the instruction decode time and T4 is the actual operation. For DAD (16bit add) 10 cycles breaks to the first 3 as setup and exectute overhead and 6 (basically two 8bit adds) spread across thre cycles. The second two cycles have one clock each of over head as the internal bus is used to transfer status to the out side world (bus idle state). >Given a 16 bit add takes 11 T cycles, that would be 2 for fetch and decode, not for the 8080, it's 10. For z80 it's 11. >4 for ALU passes, and 5 for who knows what. Probably moving things too and >from internal registers, that would explain why a 16 bit increment could be >done in 6 T cycles, 2 fetch+4 ALU passes. keep in mind the internal busses are few, so if status has to be moved to to the TEMP for a bit test the bus takes a cycle. Z80 adds little overheads like refresh (ever wonder what bus is used to get R tot he low address bus?). Allison

How old is this PDP8?

by kees.stravers＠iae.nl

Now you made me go and take off the cover! :-) I didn't dare to do so at first, because of the limited space, but nothing got damaged and it paid off.

Macs to Collect

by mranalog＠home.com

Kelly <KFergason(a)aol.com> said: > What I would like to end up with is a list that looks like this: > 128K Mac Original FWIW and IMHO, I really consider this two computers, the "Macintosh" and the "Macintosh 128K", I have both. The "Macintosh" was introduced in January 1984, the case was changed later that year (I believe about the time the Macintosh 512K was introduced) to say "Macintosh 128K". If you want to add something truely unusual to your collection, look for a "MacCharlie". Find one of these and then you'll really have a fat Mac! http://www.mandrake.demon.co.uk/Apple/charlie.html I still have not gotten around to trying to fire mine up. If you want to get technical, get some copies of the old MacTech/MacTutor magazines. (Started in December 1984, it was MacTech for the first three issues then became MacTutor, now it's MacTech again) I also have "The Complete MacTutor" and "The Best of MacTutor". They sell a 15 volume CD collection that includes the entire archives of MacTech Magazine through June 1999 and volumes I-VI of Inside Macintosh. http://www.mactech.com/cdrom/ Good luck in your searching, --Doug ========================================= Doug Coward Press Start Inc.

The base data paths for z80 and 8080 are 8bits. Key words are "data paths" as the alu on 8080 is basically 8bits (with microcoded 16 bit ops as two sequential 8bit ops). Usually the size of the data word is the metric. What confuses the subject often is the instruction word size (4004 is really 8bit then) or the ability to manipulate smaller than word size (VAX and pdp-11 byte ops). >Try asking programmers what width processors are instead of hardware >engineers. They'll tell you that the 8080 and Z-80 are 8-bitters, >and that the 68000 and IBM 360 (most models) are 32-bitters. generally agreed. It when you start playing with math ops and addressing range that the "size" is noticeable and significant. However if you look at most cpus there is a basic word size and alu size that are amoung the defining parameters. Allison

Farallon EtherWave NuBus (barely on-topic)

by spectre＠stockholm.ptloma.edu

This squeaks by but I think it's still on topic :-) I landed a Mac IIci w/24MB RAM, an 832MB HD, an 8*24*GC NuBus video card (which will go to the IIsi), the 32MB cache card, and treasure trove of all, a Farallon EtherWave NuBus card which works wonderfully. Total cost: "take it away it's consuming space" Anyway, I decided this would be a fine box for putting NetBSD/mac68k on (and I've got the NetBSD Foundation CDs on order). Then I noticed the card has *two* Ethernet ports on it, which makes me wonder if I can assign them to separate network interfaces. Anyone played with this card and know what the difference between the ports is? Can I assign them different network interfaces, either in NetBSD or in MacOS? I didn't see an option under the TCP/IP control panel (System 7.6). -- ----------------------------- personal page: http://www.armory.com/~spectre/ -- Cameron Kaiser, Point Loma Nazarene University * ckaiser(a)stockholm.ptloma.edu -- TODAY'S DUMB TRUE HEADLINE: Plane Too Close to Ground, Crash Probe Told ----

VMS BBS network (part 2)

by healyzh＠aracnet.com

This is basically a repost of info I sent out to comp.os.vms earlier in the week. However, I'm not sure it made it out of my ISP since I can't find it in DejaNews. Anyway I'm basically stuck on getting the DECnet over TCP/IP working through my firewall. What follows is the info I'd posted to the newsgroup: I'm trying to setup a VAX behind a firewall to accept DECnet over TCP/IP connections. I'm running OpenVMS V7.2, DECnet-Plus, and TCP/IP V5.0. I've got the following setup: VAXstation 4000-60 <----> OpenBSD Firewall <----> Internet AlphaStation 500/333<--+ The Firewall is doing NAT and I've redirected ports 102 and 399 directly to the VAXstation-60, which from what little documentation I could find on DECnet over TCP/IP looks to be enough. I've got DECnet over TCP/IP working just fine between the VAX and the Alpha (I set it up on the Alpha only for the purpose of testing this). However when I try and connect to the VAX from the Alpha using the Internet IP address I can't. This seems to indicate to me that I need to redirect more than just ports 102 and 399. The following four lines seem to be the only network traffic when I attempt a "SET HOST {Internet IP Address}". 15:21:54.144064 alpha.1062 > firewall.399: S 929664000:929664000(0) win 16384 <mss 1460,nop,wscale 0> 15:21:54.144066 firewall.399 > alpha.1062: R 0:0(0) ack 929664001 win 0 15:21:54.146016 alpha.1063 > firewall.399: S 929728000:929728000(0) win 16384 <mss 1460,nop,wscale 0> 15:21:54.146018 firewall.399 > alpha.1063: R 0:0(0) ack 929728001 win 0 Does anyone have any idea what I need to do in order to get this working?

Macs to Collect

by KFergason＠aol.com

Hello everyone, I would like opinions on which Macs to collect. I have a source of older Macs, and while the 'one of each' theory sounds good, its a bit impractal. What I would like to end up with is a list that looks like this: 128K Mac Original Mac II First color Blah Blah First PPC Blah2 First Notebook SE30 Powerful small footprint mac.. I am reasonably familiar with the Mac line up to about the IIci/cx timeframe. I am completely unfamiliar with the PowerPC line. All opinions welcome, reply to me or to the list. thanks, Kelly KFergason(a)aol.com

Who asked for these free VAX8350 boards?

by claudew＠sprint.ca

Hi I mentionned I was given a VAX8350 for free about 2-3 weeks ago on here. I had no place for it. So I just picked up some boards from it like someone asked me on here. I got no news from him since. I have 13 boards from what I suppose is the main unit of the VAX8350. All measure about 9"x9" some memory (4MB?) some with a 68k CPU...some I have no idea what they do... If the person does not get back to me these are going in garbage or to whoever wants them -- soon...shipping is from Montreal, Canada. My basement is outta control and I am doing some major cleaning. I dont need these...reply quick. Claude

10base2 / 10baseT (again)

From: Tony Duell <ard(a)p850ug1.demon.co.uk> >Surely a teletype would have a current loop interface, not RS232. The Correct TTY is not DTE as it's not rs232. >But this doesn't explain why the RS232 data lines are connected as a DTE. Computer used as terminal would be DTE. Also likely is the designer was not familiar with standards and went with the only RS232 they knew which was likely a terminal.

cool stuff

by jhellige＠earthlink.net

Well today I was able to go and pick up the SOL-20 that I had arranged for. It included a bunch of interesting stuff, including the original manuals and Panasonic TV monitor and cassette recorder. Also part of the package are the following: - MCS6500 Microcomputer Family Hardware Manual, August 1975 - A Guided Tour of Computer Programming in BASIC, (c) 1973 - Processor Technology Extended Cassette BASIC, p/n 727019 It would appear that this particular system was purchased at either 'Recreational Computer Centers' in Sunnyvale, CA or 'The Byte Shop' in Santa Clara, CA in late 1977.
