The card has trouble with high transfer rates. The on-board BIOS allows you to limit that to 5MB/s; when I slowed it down to that, it worked fine for me. YMMV (rather, HMMV), etc... -dq

IIgs using hard disk 20

This is going to be a head scratcher for me for some time... I distinctly remember hooking it up to my 128. (I can picture sitting in front of the table working on it...

IIgs using hard disk 20

by healyzh＠aracnet.com

I don't think the one that he's talking about is SCSI, it plugs directly into the floppy port on a Mac 128k or Mac 512K. ISTR, using one on a newer Mac Plus instead of a SCSI drive as I needed something of that formfactor and that was all I could get my hands on at the time. Based on how it's used, I'm guessing you're right about it being a MFM drive, but I suspect it's some wierd sort of bridge in it. Zane > I think I've got an old Hard Disk 20 and it's a SCSI device.

Anyone have one of these in use and could possibly be a source for a copy of the manual, disks, etc? Just bought one on auction but of course no docs or software and this is NOT SCSI to the server, it works on the LAN and has SCSI drives in it. Even if someone can send me the manual so I can scan or copy it and send it back that would be great too and maybe I might have something excess here (besdies actual cash to pay the shipping and materials back) to express my thanks.

Ah, yes, remember them well, and the mechanical B series they replaced; might even still have some parts and ledger cards... Those were the days, programming with metal punches and tweaking and debugging with a file... made great desks when they were scrapped... But while on this topic, anybody out there doing anything with Burroughs L series or B80/90 systems? Have tossed most of it out, but still have some cards, manuals and a cassette drive with controller if anyone's at all interested. And of course some paper and mylar tape stuff... And some Burroughs calculator manuals, mechanical and electronic.. mike ---------------------------- Date: Sat, 13 Oct 2001 17:29:07 -0500 From: "Patrick L. Boland" <plboland(a)home.com> Subject: Re: Burroughs E6000 As late as 1977 ! was using two Burroughs E6000 computers to perform the function of loan payment application. The loans were for health club membership in the Chicago area and a great deal of the rest of the upper midwest area. We had over 50,000 loans outstanding at any time and processed from 1,000 to 3,000 loan payments a day. The machines we had were magnetic stripe ledger card readers and they would punch an output card with the results of the processing of the transaction. The latest information about the loan kept on a master deck of cards was replaced with the card that was punched as a result of the transaction on the E6000. The update was performed on a daily basis using the 085 sorter and a reproducer/collater. During the last 8 to 12 months of the use of the E6000, while a conversion was being worked on, we used only one E6000 and kept the other one for spare parts. Burroughs had run out of spare parts.

My 512k has video problems >and I haven't had a chance to sort those out so I can test the HD20 on it. Not to double reply... but now I am going to start beating my head into a wall. Apple's technote article # 8169 (in the archives section), claims that the only way to add a hard drive to the 128 and 512 is by using the HD20 non-scsi drive (the one in question here). This seems to contridict a previous technote that lists the first supporting mac as the 512ke. So now I am REALLY going to have to pull out my 128 and see what happens... it seems Apple doesn't even know which way it goes. -chris <http://www.mythtech.net>

It was the second generation before really complex LSI actually the '181 was likely the highest gate count part in the class before the TI bit slices (74881-884). It's also very old but still a handy part as it does all the standard arithmetic ops and logical ones too. The ALU core of the 2901 is basically the 74181. Allison

It might be the same as one in "AT&T" since they coined the term, or it might mean "twisted pair" because that's how T1 lines were originally made.

ArcNet and the Pursuit of Multiple Topologies

by jruschme＠Mac.com

Sounds a lot like a box I've been threatening to build for a while. On the Ethernet side, I'd not worry about specific 10bT and ThickNet segments. Instead, I'd run a single 10b2 (ThinNet) segment and get a 10bT hub with a BNC uplink. This also had the advantage of saving you a slot in the box. Don't worry about ThickNet, just pick up a couple of spare 10bT or 10b2 tranceivers for the odd box with an AUI port. Since you've got LocalTalk running to the box, then I'd also run MacGate which would let you run MacIP (IP over LocalTalk). As for other fun topologies, you already mentioned TokenRing. My personal choice would be to also add HomePNA (Ethernet over phonelines). The 1MB HomePNA 1.0 cards (the only ones supported by Linux)are very cheap these days. I picked up a pair from Computer Geeks (http://www.compgeeks.com) for something like $12. Now if I could just find a cheap Ethernet/HomePNA bridge for the Nubus Mac in the spare bedroom... <<<John>>> -----Original Message----- Date: Tue, 9 Oct 2001 12:50:01 -0500 From: Tarsi <tarsi(a)binhost.com> Subject: ArcNet and the Pursuit of Multiple Topologies Dear all, I've decided that one of my goals is to run every networking topology possible in my house, regardless if I actually NEED to run them or not. :) My plan is to place 1 linux box running a card from each topology in it and use that to bridge all (or almost all) topologies. I currently have running 10bT ethernet, 10b2 ethernet, Localtalk over PhoneNET and the beginnings of Arcnet. In light of such, I have a series of questions: 1) Who knows some stuff about ArcNet? I've gotten 4 cards (8-bit ISA) and a 16-port active hub. I've read somewhere that cards are either hubbable or not. Any other info on that? 2) Anyone have any (I think it is) 93ohm coax arcnet patch cables that they want to get rid of? 3) Anyone got good resources on ThickNET? (10b5 I think it is?) I know it was run back in the day, and I know some precursory things about it (the funky vampire taps, etc.) Anyone have either resources or hardware on this topology that they'd like to share/sell/etc? :) 4) Any other interesting topologies I should try? I have plans to do: Arcnet, FDDI, Token ring, Localtalk, 10b2, 10b5, 10bT, 10bTX, 10bFiber, and (eventually) 802.11b wireless.

OT: Dark Tower

by mythtech＠Mac.com

> What exactly IS Dark Tower? I've heard of Dork Tower (a comic book) but >not Dark Tower. If you prefer to answer off list, that would be fine too >8-) Well, if the original poster was refering to what I had, then Dark Tower is a board game (circa late 70's early 80's). The board was this roundish board that you moved all over, and there was a dark brown plastic castle thing that sat in the middle. The object was, you were an adventurer, and you had to move about getting things (treasures?) from each land (4 lands, 4 players IIRC). When it was your turn, you would press a button on the tower (I think there was "pass" for do nothing, "move" to go somewhere). It would then spin (well, the inside would spin, the tower stayed still), and eventually stop, telling you if you ran into enemy's, or treasures, or whatever. If it was an enemy, you had to fight them, and it would track your possestions and army strength, and would tell you how you did (how many people died, how many of the enemy joined your ranks, if you got new possestions) Basically, it was a 4 player, board game version along the lines of D&D (and was out when D&D was in its hayday, something else I am afraid to admit I was in to.). I would be happy to pull mine out (I am sure it is in my parents basement still, I have to go over there today anyway to fix my mother's computer), and I can take some pics of it, and scan the directions if people want. Of course, maybe the original poster was refering to some other Dark Tower game, and I now look like a total ass (but the one I know of was really cool, so even if I just get to tell others about it, it was worth the typing). -chris <http://www.mythtech.net>

Semi-OT : 4063 pinout

by r_beaudry＠hotmail.com

Tony, According to a datasheet downloaded from www.freetradezone.com (free registration, and supposedly 12 million component datasheets -- I believe it, as there's yet to be a part I haven't found).... It's a CMOS 4-bit magnitude comparator... 1: B3 2: (A < B) IN 3: (A = B) IN 4: (A > B) IN 5: (A > B) OUT 6: (A = B) OUT 7: (A < B) OUT 8: VSS 9: B0 10: A0 11: B1 12: A1 13: A2 14: B2 15: A3 16: VDD I can email the datasheet if you'd like.... It's a 220KB .PDF file... Rich B. "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." -- Ben Franklin

CompuPro and 86-DOS

by mranalog＠home.com

This last weekend I pulled my old rack mount CompuPro system out of storage and cleaned it up. The last time I used this system was about 15 years ago and I only used it to edit my resume in Wordstar. The system consists of: a "CPU 8085/88" a "DISK 1" controller a "SYSTEM SUPPORT 1" for the console two "RAM 16" boards for a total of 128K and two Qume 842 8" floppy drives After one small capacitor fire I had the system up and running. I went through all of the 8" diskettes I could find to determine what would boot. So far, I have bootable disks for CP/M 2.2, CP/M 86, and CP/M 8-16. But the disks that I really want to read are in 86-DOS format according to the label. I have disks that claim to be 86-DOS boot disks but they wouldn't boot. Some of these disks I'm having problems with appear to be SSSD 26 sectors/ 128 bytes if that helps. Can anyone point me in the direction I need to go in order to be able to boot 86-DOS?

problems generating OS8 system tape.

by jos.mar＠bluewin.ch

After finally getting my TU56/TD8E setup operational, I now run into problems generating an OS/8 system tape. The system keeps insisting that "TAPE #2 is not an original dec tape", although i know for a fact that it is. I have 3 sets of system tapes and all generate the same error. Tape #1 is never asked for, the resulting tape is of course not usable. Any clues what I'm doing wrong ? Jos Dreesen

SCSI Info requested by David Woyciesjes

by dec.parts＠verizon.net

Hello David, I finally got at that info you requested. It turned out that there was some other related info that I thought you might like also. Probably more than you've ever wanted to know about SCSI, up to SCSI-3 info? Of course it was being stored on a SCSI drive that, at the time, wasn't hooked to this system, which is why I asked for your patience. Anyone who is interested must DL and save it within the next couple of days, as I have very limited web space and can't leave it there long. This is the only time I can post it. So, perhaps someone else with more space can host it for a longer period of time. http://members.bellatlantic.net/~vze2mj6m/scsi_info/scsi-info-15kb.htm http://members.bellatlantic.net/~vze2mj6m/scsi_info/scsi_faq-145kb.txt http://members.bellatlantic.net/~vze2mj6m/scsi_info/scsi2-spec-1632kb.txt Sincerely, Bennett

Slightly OT: What to do with a DEC 3000/300?

by ken＠seefried.com

Sorry to be late to this topic. As it happens, I've got a DEC 3000/300X (175MHz 21064, 64MB RAM, 2x2GB Disk, NetBSD 1.5.1 + fixes) in production. I'm fond of it, but probably more for the fact that it comes in a rackmount sled, which appears to be quite rare. It fits nice at the co-hosting facility (it's www.thistle.com, but it doesn't talk to anyone but me right now). What I know: Memory: No...you can't put just anything into it. It's got 8 72-pin SIMM slots, but it will only accept 8MB, true parity, generic SIMMs (giving 64MB). And it's damn finicky about those. My 3000s spits on SIMMs that everything else in the basement has no trouble with. It will also accept Digital custom 32MB true parity SIMMs (giving 256MB). Nothing else that I've found will work, but that could just be me. If anyone has any of these SIMMs they don't want, do let me know... Video: AFAIK, none of the free *nix systems support the built in TC frame buffers. VMS and OSF/1, nee Tru64 do. The 3000 will run X clients and display to another machine. Real men do serial consoles anyway. Speed: Slow. Really slow. Not PC532 slow, but not something I'd trade one of my PPro 200s for (other than the swanky rack-mount sled). Definately useful for low volume web, mail, etc., but "make build" isn't pleasant. My PC64-275 is way, way faster, but still not that fast. There's lot's of good info out there, and I know there are people working to support all that isn't currently supported. Drop me a note if anyone wants to know anything else. Ken

The stringy floppy is flawed the same way an 8-track audio tape is -- it only moves in one direction. As a result, A&J didn't write any OS for their drives, just a couple of simple commands.

Strange, but interesting, stuff. Ahh, neat! I've heard a bit about Wang VS systems, but I had no idea they were TTL CPUs. Very cool. How wide is the processor? The 74LS181 is 4 bits wide...how many does it use? Have you had a chance to take pics of this system? I'd be highly interested in seeing them if so. -Dave -- Dave McGuire Laurel, MD

Cromemco Pick-up on 10-13-01

by jrkeys＠concentric.net

This pass Saturday was a long drive MN to IL (12 hours total drive time) to pick up 2- Cromemco System Three's, a Systemv CS-300, one new in the box KB for these systems, lots of manuals and software for them, a Cipher 1600BPI tape unit, a model BRZ-III fan for the units, and some parts. All will have to be cleaned up as they are pretty dirty and need some loving care. The guy had over 1600sq feet of computer stuff he is selling most on eBay.:-( At a local thrift I got some Sega master stuff, like the 3D glasses that have been selling on eBay for $50, I got mine for a couple dollars. Got a Virtual Boy system for $11.99. Got some Atari 2600 stuff also they were selling cartridges for 80 cents and they had two big boxes full. Now I will start the clean-up and entering all the info into the database (my paper notebooks). Keep computing John
