I'm not in the area. I do have an enclosure for a MicroVAX II, and some boards (CPU and some RAM) I believe I tested the CPU, and it's working. The RAM may not work with that specific CPU, and the enclosure has power-supply problems. (basically it's all left-overs from when I was trying to get parts for mine) I don't want to ship, though, since it may as well be a 3-foot-tall block of solid lead.

In either case, the high > freq response is already lost, but during playback/recording, > you might actually null out some high frq noise... As long as we're hypothetically copying hard to find tapes, and willing to shell out for hardware, you might also consider a recording device that was designed for the task. It seems to me that one can get a decent digital multitracking device for the cost of a decent multitracking software package these days ;) (I may be exaggerating here... but they're cheap) For instance, I've seen a new unit -- a Boss BR-532 -- which records on "smartmedia" (4-track), and lists around $400 (I think). I hear that the 128M cards, which are said to hold 90 minutes of audio run about $45. Obviously this uses some compression, and you wouldn't get the best quality, but it would provide an easy way of mixing some of the hiss out and adding some mastering effects if you'd like. This might also be problematic for recording a cassette tape since I think it only has one channel in. (You could do it, though) I wouldn't use this for doing original recording personally, but for re-mastering a cassette, or other light-duty stuff, it may be just the ticket. I personally have a Fostex VF08, which I paid about $480 for from audiolines.com, but which lists around $599. It's a slightly more heavy solution, and has 5GB or so of disk in it. No compression, sound records at 44.1khz 16-bit. The unit also has 20-bit ADC and 24-bit DAC with 64/128x oversampling respectively. It's an 8-track unit with 2 channels in. I can tell you from experience that this machine could probably make "smashing pumpkins" sound good. (My opinion, of course... and don't get me started on "smashing pumpkins.") (These are mostly from memory, so I might be wrong on some of this... look it up) At any rate, one could record, mix, and master the cassette on a similar unit, and transfer the resulting digital audio to your computer through the SPDIF digital out. Wow, that was tangential. Regards, Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

Hey people. I was wondering if anyone here were familiar with the internals of the Sun Roadrunner (386i). Specifically, I am looking for someone who can tell me exactly what is different between a Roadrunner and a PC. Depending on how difficult it will be, I might try to build a modern Roadrunner from new commodity components. I have an actual 386i/25, and a 486i for compatibility testing. Peace... Sridha

FLUKE?

The problem may be that it's not a SCSI TK50 but the SASI interfaced TK50 for the MV2000. The difference is the firmware on the SCSI/SASI interface card.

TK50-GA external SCSI tape unit + Microvax 3100 Desktop

by Adrian.Graham＠corporatemicrosystems.com

If the TK50 is terminated and the SCSI IDs are correct (tape drives historically were ID5) and it's not seen at the console then something's broken :) There should be a DIL switch on the back of the unit to set the ID if I'm remembering right, and if you've got a stock MV3100 the internal disks will probably be ID3 (system disk) and ID0 or 1 (data). What SCSI cable are you using? To check that the drive itself is OK you can always take it out of its expansion box, whip the cover off the VAX and connect directly to the internal bus next to the 2 disks.

TK50-GA external SCSI tape unit + Microvax 3100 Desktop

by Antonio.Carlini＠riverstonenet.com

> The machine has two scsi buses or ar least two SCSI connectors back, > one large and another of lightly minor size. I cannot think of *any* MicroVAX or VAXstation that has two SCSI connectors of *different* sizes. The VAXstation 3100s pretty much all have a single SCSI connector (the small size - HD68 is what I've seen it called in the past). The VAXstation 4000-9x/60 have one Amphenol 50-way SCSI connector (the expansion boxes have two, but connected as an in-out bus). I forget about the 4000-VLC, but it cannot really have room for more than one connector! The MicroVAX 3100 series machines are all (IIRC) in one of two similar boxes - the only difference being the height (the larger one has two trays on to which hard drives may be mounted - the smaller one has only one tray). Looking at the back, there should be three connectors across the top (I think these connectors are always there, even if they are not used internally). The right-most connector (looking from the back, I think) should be the SCSI port; it is a 50-way amphenol connector. This is the same as the conectors on a TK50Z. Antonio arcarlini(a)iee.org

PDP-8/E bulbs

by healyzh＠aracnet.com

I'm making progress on the PDP-8/E I got this last week. The powersupply checks out once the Front Panel is plugged in, and thanks to all the spare lightbulbs I've got all the burnt out bulbs replaced. Unfortunatly I'm now down to two spares which my -8/m could probably use, the -8/e had nearly half it's bulbs out. This brings up the question, how hard is it to get replacement bulbs?

Hi Curt, > While I don't have every single ST component listed, the ST section under > Atari Computers on my website should be of help to you: > www.atarimuseum.com Of course I checked your web-site first for infos about the 4160STe :) Perhaps some day you have the time to make a complete list of all Atari Computer Systems - I think there are quite a few unkown systems like the Atari ST520+, CLab Falcon MK I, II and X - there also was an Atari 520 STE - very strange ... > The 4160STe was going to be a 4mb Europe release of the ST but was > cut from production at the last minute, a few samples are floating > about, perhaps my machine is one of those. It has a 4160 label - although I am not completly sure if it is an original factory installed label or if it has been added later due to a memory upgrade. On the bottom site the label reads "1040STE" and has a large black sticker "4MB".

1) 1890 Hollerith Tabulation System. Mechanical machine to sort US census data. Hollerith's Tabulating Machine Company, TMC, was later to merge with Computing-Tabulating-Recording Co, later to become IBM (1914) 2) 1937-41 Z1 and Z3 built by Konrad Zuse and Helmut Schreyer Z1 first binary machine. Z3 first floating point machine (used 2600 relays). Speed was 5Hz ! 3) 1937 Automatic Sequence Controlled Calculator (ASCC) or Harvard Mk I Part vacuum tube - part relay. Hard wired coding. Code written by Grace Hopper. According to Ms Hopper - moths would fly in through the open windows at night and get stuck in the relays. This would render the machine unless and it would have to be "de-bugged". 4) 1940 ? Enigma - Electromechanical state machine. Colossus wouldn't have been built without it. 5) 1943 Colossus - Vacuum tube code craker. Not a general purpose machine, built solely to solve Enigma ciphers. Hard wired coding and paper tape. 1500 valves. 6) 1944 ENIAC - First general purpose machine. Hard wired and paper tape program, worked in decimal. Program storage added after development of Manchester Mk I and EDSAC. 7) 1946 Manchester Mark I - First stored program computer. The Williams tube (CRT) was used for program storage. Commercial version was the Ferranti Mk I Followed by EDSAC in 1949. 8) 1951 UNIVAC - first successful commercial computer. One of the first machines to use compiled software, another of Grace Hopper's ideas. 9) 1951 LEO I (Lyons Electronic Office) J. Lyons & Company Ltd First British mainframe. Lyons bought by English Electric Company later to become ICL and the end of the British computer industry. 10) 1956 MIT Lincoln Labs TX-0 - First solid state computer 11) 1964 CDC's 6600 - Seymour Cray's first super computer, 3 MIPS 12) 1965 DEC PDP8 - The first true minicomputer 13) 1968/9 The Apollo guidance computer - Helped get man to the moon. 14) 1971 Intel 4004 - First commercially available microprocessor 15) 1972 HP 35 - Perhaps the first scientific pocket calculator ?

Altair, 8080 assembler

by rschaefe＠gcfn.org

Anyone have a quick rundown on the front panel operations for an altair? I've been playing with altair32, but I never had the real thing, so I can only guess at what some of the switches do. And maybe recommentations on cross assemblers (x86/win32), or at least a LART in the right direction? My google searches aren't too helpful. Thanks! Bob

Tall Tree Systems`JRAM-3'

by rschaefe＠gcfn.org

Anyone know what this is? It came from a 256K IBM XT, I thought at first it was a video card, (it was in the first slot), but it's got eight banks of nine 41256 ram DIPs on it. That sounds like a lot for a mono video card, doesn't it? Combo card? it's got a looong double-row of pin sockets along the bottom just above the ISA connector, and another single row up the whole edge between the external connectors (male 9 pin & female 25 pin) and the components. Maybe a daughter board? It's got one 6-position DIP switch at the top right (^vvvv^) and 3 three-pin jumpers along the top near the rams, (xx. xx. xx.) It's got a couple've big (1/8") holes on the board, lending credence to the daughterboard theory. All the chips are labeled in an intersting way-- u84 158 is --get this-- a 74LS158N. Don't ya wish everything was made like this? The computer it came out of looks pretty interesting, aside for a decade's worth of grime on it. A whopping 256K ram on the motherboard, 2x internal floppy, Adaptec HDD controller, external (!) ummm... 20? Meg drive in a case that _looks_ like an IBM part, but it doesn't actually _say_ IBM anywhere on it. Connects via IDC connectors on ribbon cable. Strange. Have to pop the case to plug it in. I hate to think just how much this setup must've cost new. ja ne Bob

MP/M and Yaze

by spedraja＠ono.com

Hello again. I have another matter that could be interesting for somebody (I hope). The Yaze CP/M emulator v.1.20 comex with support for switched memory banks (in appearence). I couldn't review the source code by now. Somebody did it ? I should like to reconstruct one simple MP/M system under it. I know some source code can be donwloaded from http://www.cpm.z80.de and I did it, bit my next problem is related with the modules needed to construct the OS nucleus, and the order of these modules. I could need a hand too with CP/M. I have some doubts about the paper of the CBIOS.ASM and BIOS.ASM modules. Finally, I'm interesting about one fascinating CP/M emulator, the ZRPM. It does one emulation of diverse models of computers that could run CP/M like the Osborne and the Kaypro. I can say that I've loadad two versions of Wordstar for every computer under the same emulator, and loaded one or another adjusting settings internally in the ZRPM telling it was worked in a Kaypro or Osborne portable. I thought all these matters was under control of the BDOS but here are more misterious. Right ? What exactly ? Thanks and Greetings Sergio

PDP-9 lives

by bsupnik＠nauticusnet.com

Hans, First, congratulations on this terrific progress! Second, a stop at 22 is probably an unexpected CAL (opcode of 0), which would do an effective JMS 20, pick up the instruction at 21 (probably a HLT to catch the CAL), and then halt with an apparent PC = 22. Take a look at M[20], it should have the PC+1 of the CAL. /Bob -----Original Message----- From: Hans B Pufal To: classiccmp; aek(a)spies.com; Bob Supnik Sent: 12/1/01 12:59 PM Subject: PDP-9 lives I am very happy to be able to announce that the PDP-9 that we have been working on for quite some time finally began talking to the world again today. We had gotten memory and processor operational, then had to fix a memory fault which developed. TTY I/O posed some problems but finally today it spoke and we could reply. We ran the only two test routines we have on paper tape: the extended memory test and the TTY test. There appears to be some issue with the TTY since part 1 test halts after a while with PC=22, no mention of that in the test writeup! TTY test part 2 runs without error. Anyways, we plan on completeing checkout on this system, fix a couple of burnt our indicator bulbs and get the punch up before starting on the second system we have. That one has a dual dectapes, then we can read the 100 or so tapes trhat came with the system, and run some real software ;-) I'd be interested in knowing the status of other pdp-9's.

jumper pin settings for ALR (non-LVD) backplane

by ehenson＠erols.com

I acquired an ALR raid cage with a non-LVD backplane for which I cannot find the jumper pin settings. I have been able to identify it as a "quick hot swap cage 3 drive board" with the following markings: 12609700 Rev. G1/A. There is also a sticker that reads: ALR s.a. # 9705/A and KIT# 3134/KS. Any direction would be appreciated. Thanks.

Okay, I think I can do that, in (more or less) chronological order no less! 1: Xerox Alto Reason: Because, after all, where would the GUI have come from without this thing? 2: IBM 5100 Reason: To show that, just because it was IBM, & it was the frist intergrated computer (sans printer), the people will not always buy it. Also I think the $16,384 price tag may have had something to do with it, I don't know. 3 & 4: Altair 8800 & IMSAI 8080 (respectively) Reason: The first commercially available computers, & to illustrate that the clone wars did not start in the 80's, they started much earlier than that. 5. Apple I Reason: Pretty self explanitory. 6, 7, & 8. Apple ][, Commodore PET, TRS-80 Model I (respectively) Reason: After all, these were "The Big Three", weren't they? 9. Compucolor Reason: (Allegedly) The first computer to inexpensively offer color graphics. 10. CBM 4032 Reason: Commodore's most famous (infamous?) business computer. 11. Apple ][+ Reason: Finally, Apple's figuring out how to be a computer company! 12. TI-99/4 Reason: TI's first foray in the computer market, as if anyone cared. 13. Commodore VIC-20 Reason: "The friendly color computer that anyone can afford" --William Shatner. 14. TI-99/4A Reason: To show that it is not a good idea to hire a pitchman who sells Jell-o and (New) Coke. 15. Commodore 64 Reason: Requires no explanation. 16. GRiD Compass 1100 Reason: I would think that the first clamshell laptop should deserve a place in computer history! 17. Apple LISA Reason: Sometimes Apple can just way too ahead of themselves. 18. TRS-80 Model 100 Reason: When these things came out, who didn't own one? 19. Otrona Attache Reason: Wow! A small "luggable", how about that! 20. Apple Macintosh Reason: "On January 24th, Apple will introduce Macintosh. And you will see why 1984 won't be like *1984*" 21.

HD Controllers - S-100 & Corvus Omninet

by mhstein＠usa.net

As far as I can tell, IMI originally used a proprietary interface but when IBM came into the game they switched over to ST506 and IMI drives were in fact put into some AT's; same HDA but a different PCB. I have various versions of the 5014/5018/5021drives and have in fact switched boards back & forth. And yes, the drive clock signals were used for data transfer, at least by Cromemco; once the appropriate sector was located, data was clocked into/out of a shift register by the SysClk signal from the drive. m -----------------Original Message---------------- Date: Sat, 1 Dec 2001 10:28:45 -0700 From: "Richard Erlacher" <edick(a)idcomm.com> Subject: Re: HD Controllers - S-100 & Corvus Omninet I had a couple of IMI drives back in the '80's and find, from my doc's that they were, in fact, ST506 compatible. I wonder if the drives you're seeing in your brocheure are earlier than that. The 8" Quantum drives all provided a clock on the data cable, that could be used to recover data. I'm not exactly sure how this was intended to be used, but several controllers for 8" drives relied on it, not having a PLL on board. The Shugart drives apparently didn't provide this clock. Dick

HD Controllers - S-100 & Corvus Omninet

by mhstein＠usa.net

Thanks for the interesting info, Frank. I thought that Corvus had used these drives because I've got Corvus ads from old Bytes and they certainly do look like these 7710's; not much else looks like these babies. But although I've seen a reference to ANSI X3T9, I gather that the interface was proprietary to IMI. Don't need the docs for the interface, but thanks for mentioning that you've got some; I've got a manual for the controller from the good old days when manuals actually told you something, as well as calibration notes for the drives, and am about to check out the drives before I get rid of them. I was just curious if the controllers are of any use for any other drives since I have more controllers than drives. If you want the Corvus board, send me a note off list & let me know where you are. mike -------------------Original Message---------------- Date: 01 Dec 2001 00:08:00 -0800 From: Frank McConnell <fmc(a)reanimators.org> Subject: Re: HD Controllers - S-100 & Corvus Omninet M H Stein <mhstein(a)usa.net> wrote: > Does anybody know anything about the HD interface bus Cromemco used > with their early IMI drives <snip> Yes, Corvus used these drives. I'd expect Onyx did too; the story is that the VC who funded IMI also funded Onyx and Corvus so that IMI would have customers. It's interesting to know that Cromemco used them too. I'm sitting here looking at a photocopy of a data sheet of sorts for the IMI 7710, and it does provide some description of the interface. 25 signals on a 34-line bus. I suspect it's somewhere between "more than I want to type" and "less than you need to know to use the drive", because I can't quite figure out how you would transfer a block of data to the drive from what's printed here. > Finally, I also have a Corvus S-100 board; looks like it might be a > host adapter for a disk drive of some sort.
