< <I will check to see if Best Buy has anymore 16 meg simms, since $25 is goo <price ?? Up north they almost give them away. < Keep this in mind... Most systems that use 30 pin simms require either sets of two (mostly old 386s) or sets of 4. So 16mb 30 pin simms are going to net 64mb ($100) of ram in a 486... The common and desired parts are 4mb. The average 486 will use either four or eight of them to net 16 or 32mb. The later being more resonable for that class of cpu. Allison

DEC Modems

by jeff.kaneko＠juno.com

Somebody on this list one told me that he was interested in genuine DEC modems. I spotted these two at a wrecking yard today: DF-112AA (1200 baud, I think) DF-03 (300 baud, I'm sure) If these old modems are of interest, I'm sure I can pick them up cheaply.

Saved a Modcomp Classic

Today I managed to sve a Modcomp Classic minicomputer from a fate worse than death. It is a tall (5ft) dual width cabinet, one housing the CPU the other a mag tape drive. It was used as a dat comm concentrator. Don't know anything about these machines. Has anyone any info? I'll try and put up some pictures this weekend.

VARIAN Core Memory

field maintenance print sets

by lemay＠cs.umn.edu

Hmm, lucky day I guess... I got a 11/780 and a 11/785 field maintenance print set (2 different printsets) from the EE department. I'm rather surprised that I didnt notice these several years ago. Also, I saw what I swear must be a quad height pdp8 board. He wasnt sure what it was, so he wouldnt let me have it yet. He thought it might be a PDP11 board (did they make quad height PDP11 systems?). Heres what the board says: Excelan Exos 204 s/n 001993 It has a 16 pin male ribbon cable connector on the top of the board, and strange 2-part female connector in the middle of the board, sort of like a 10 pin and a 36 pin ribbon female connectors joined together so that there is a slight gap between them. some intel chips on the board are dated 1982, the board itself is dated 1984. Anyone know what this board is? -Lawrence LeMay

RT-11 ARGH!

by healyzh＠aracnet.com

Is a RT-11 Media Kit on TK-50, that was built under V5.4 using some command which currently escapes me, bootable? I just realized that apparently V5.3 doesn't support TK50's. BLEEP!!!! I'd just try it, but don't want to have to type in the bootstrap if it isn't. Rather spend the time trying to figure out the best sequence of hoops to jump through if it isn't! BEEEEEEEEEEEEP! Just when I was starting to make some serious progress at getting my /73 put back together. BLEEP! On that note, I think I'd best get some sleep. Zane | Zane H.

Paper Tape Loading of Software?

by jhfine＠idirect.com

This question is most likely to be answered by Megan Gentry since I don't know of anyone else who might have the background. In the very distant past, I used to prepare paper tape programs in so-called LDA format from an RT-11 based system. Since I don't and likely won't have access to a system with a paper tape reader (let alone a paper tape punch), does anyone remember if the program that does get loaded can also be prepared as an SAV file by setting the appropriate directives to the MACRO assembler and then the LINK program?

Nerds have truly arrived

Here's a short tidbit I found in today's paper: Talk about good rebounders--Mick Jagger's ex, Jery Hall, appears to have taken up with one of the world's richest men, Paul Allen, who with Bill Gates founded Microsoft. Britain's Daily Telegraph says the model, 43, is vacationing on one of Allen's yachts in the south of France. Allen, 45, is way richer than the Rollling Stone--$22 billin to a few hundred million--plus, like Jagger, has a liking for rock, playing guitar in his own band, the Threads. Geek *IS* chic!

Normally there is absolutely no problem in not using all of the disk. RT and the DU handlers will only care about what you tell them about (via PORT,UNIT,PART). The only thing you might have to worry about is a program which uses the SPFUN which allows total access to the disk (which is not something which you will find in any of the standard RT utilities).

Wow!. I am impressed (very). Although I often thought some of the stuff in the RK05 service manual was a little OTT. Those drives _are_ pretty robust. (The HP drive that we're discussing here uses similar technology to the RK05 and will have much the same flying height, etc. So I sould guess that drive will be similarly robust). > RK's fly so high they actually ran a year in a machine where the tech > left the filter caps on. I assume you mean the dust caps over the ends of the absolute filter and not the filter capacitors in the PSU. You mean that drive had no airflow at all? Again, Wow! > > As far as flying height, RK05's are the SR71 or U2 of the disk heads. :-). RK05s (and similar drives) are good to learn on, because it's difficult to get a fatal headcrash. I've seen it happen once, or rather I got to change the heads after it had happened. That head had visible scoring across the pad. I suppose it might have cleaned up, but I had new heads in stock anyway... But most of the time if you stick in a damaged platter or have other problems, you get the 'ting, ting, ting' noise long before the head is ruined. -tony

A few years ago I decided to get a formal qualification in electronics (I've been a hobbyist since '77).

"Primitive" systems like these (and Apples and Beebs) I think are far better animals on which to learn the inner workings of computers, far too much is hidden away inside the VLSIs our PCs are made from these days. :-( TTFN - Pete. -- Hardware & Software Engineer.

Floppy drive info needed

by Glenatacme＠aol.com

Hello all: Does anyone have jumper information on these two old drives? Both are 5.25" drives pulled from old PCs. The jumpers are not marked (except for jp1, jp2, etc.). I need to configure them for use with a TS2068 fdd i/f. The drives are: Epson SD-621L Teac FD55-GFR If you can point me in the right direction I'd appreciate it. Glen Goodwin 0/0

14" hard drive refurb....

by edick＠idcomm.com

You'd be better advised to use a really fine diamond lapping paste as you might obtain from an industrial supplier. There are fine enough pastes available that one can lap to a .000003" finish . . . essential if you're making Jo-blocks, but probably overkill for your task. If you contact an outfit like Manhattan Supply Corp, which has branches throughout the U.S, you'll find something suitable and probably in a quantity you can afford. If you're worried about the head flatness, I'd not try this trick until you're more sure of yourself, though. -----Original Message----- From: Tony Duell <ard(a)p850ug1.demon.co.uk> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Tuesday, August 10, 1999 3:24 PM Subject: Re: 14" hard drive refurb.... >> >> Ok, I know this sounds crazy.... >> >> One person told me that if the heads were heavily oxidized, that they could >> be cleaned with a soft toothbrush and TOOTHPASTE (followed by a rinsing in >> 91% alcohol)??????? >> >> Anyone know if this is crazy or advisable? > >Toothpaste is a fairly mild abrasive that does sometimes help in >cleaning/polishing things.

14" hard drive refurb results?

by jlwest＠tseinc.com

Well, I got enough of the oxide off to see there is definitely a few scores in the ceramic pad. Since I'm a total neophyte at this, I decided to get some professional help (related to the disc heads <grin>). I located an outfit with the following prices: 1) New heads - $135.00 each 2) Replace the pads, check the spring, and test fly - $35.00 each 3) Clean and recontour the head - $20.00 each. Just to be safe, I'm probably going to go with option two, and at least I'll be sure the heads I'm putting in aren't going to destroy the platter. Does anyone know of an outfit that gives better pricing here in the states? Jay West

Weitek Array Processor

by svs＠ropnet.ru

G'day, In the past, I've asked for information on the Weitek [Graphic] Array Processor. Well, I've located some documentation for it and accompanying software: WAFT, Weitek Assembler with Flexible Translation, APSIM, Array Processor SIMulator, and QUAKE :-). The board has one integer processor (an equivalent of 4 Am2901's + Am2910) and one floating point processor (2 WTL1066 register files, 1 WTL1032 ALU and 1 WTL1033 multiplier). Manual claims that performance of this hardware reaches 8 MFLOPS. Clock frequency is 4 MHz. I've not found any reference to this product (by name) on the Net. From comments in source code, it looks like Thomas J. Riordan, Craig Hansen, and Michael Ekberg were involved in the design of this product. Does anyone remember this product? I'll have to verify that hardware is working, but there is a good chance that it is OK. -- Sergey Svishchev -- svs{at}ropnet{dot}ru

VAXstation 8000

by svs＠ropnet.ru

G'day, I fired up a VAXstation 8000 that was sitting in a corner collecting dust. After some fiddling, I managed to get it to work -- at least partly. It would not even show the chevron prompt until I pulled the KK810 cable (KK810 is "Control Assembly") out of GIF (Goes In First) BI bus terminator. Even then, no luck: (DU50 is a RD54 that is hung off KFBTA) Hand transcribed logs: Plain boot: >>> B DU50 01000000 %BOOT-F-Failed to allocate PFN bitmap Boot with memory test disabled: >>> B/R5:84 DU50 01000000 %BOOT-F-Unexpected exception PC=000003E1 >>> B/R5:2004 DU50 01000000 %BOOT-W-Ten percent or more of main memory is bad %BOOT-F-Insufficient memory for CI Boot with boot breakpoint set: >>> B/R5:20 DU50 1 BRK AT 00003E8C 00003E8C/7E5BD001 Something is obviously wrong, but without docs I am going nowhere...

VAX support until 2010?

by jfoust＠threedee.com

I, like other DECUS members, just got a letter from Compaq assuring me that VAX (and OpenVMS) support will continue for another ten years - although the VAX family will be retired. Now wouldn't that letter have been much more exciting if they'd decided to open-source all the other retired DEC products? - John

RT-11 DU: Handler Question

by mbg＠world.std.com

>OK, as long as I don't run into any unforseen trouble that keeps me from >having time, I plan on installing RT-11 on a large disk in the next few >days. However, I won't be using the nice WQESD ESDI controller that I've >got that makes partitioning disks easy. So I want to make sure I >understand how partitioning works under RT-11. Doesn't it do the partitioning in hardware anyway? Of course that is easy... they become separate units... >If I'm reading the manuals correctly I would first boot off of my RL02 >pack and do the following > >.INIT/BADBLOCKS DU0: > >then > >.SQUEEZE/OUTPUT=DU0: DL1: >.COPY/BOOT DL1:RT11FB.SYS DU0: That should be .SQUEEZE/OUTPUT:DU0: DL1: .COPY/BOOT DU0:RT11FB.SYS DU0: >and then boot the system from DU0: So far that's pretty straight >forward, and except for using SQUEEZE to copy the distribution, pretty >much the way I got it from RX50 to RL02. Squeeze is a faster way of doing the copy when the output volume is a freshly initialized volume. You could do it with a COPY/SYS... >Now then since I'll want to use more than just the first 30Mb of the Hard >Drive, I'll need to set up partitions. Do I do this prior to >initializing DU0: or after booting from a freshly installed DU0:? There are a number of factors involved... you need to ensure that the partitioning in the DU driver you are using to write to the DU device is the same as the DU driver which gets written *to* that device. If not, you could write the data just fine, but not be able to find it easily. An example of this might be having a specially-partitioned XM version of the DU driver. You use it to copy a system to some other partition, but you set it to boot RT11FB (which uses a different copy of DU -- the one built for SB/FB) and then boot the volume... when it gets up far enough that it tries to use the FB version of the handler, it references an entirely different partition. >I realize the command to do the partitioning is: > >.SET DU0 UNIT=0,PORT=0,PART=0 >.SET DU1 UNIT=0,PORT=0,PART=1 >.SET DU2 UNIT=0,PORT=0,PART=2 >.SET DU3 UNIT=0,PORT=0,PART=3 Personally, I like to think more hierarchically, doing the PORT, then UNIT, then PARTition. But yes, this could work. I also tend to keep the DU0-DU3 devices mapped to partition zero of the corresponding physical units: .SET DU0 PORT=0,UNIT=0,PART=0 .SET DU1 PORT=0,UNIT=1,PART=0 .SET DU2 PORT=0,UNIT=2,PART=0 .SET DU3 PORT=0,UNIT=3,PART=0 and then assign the non-zero partitions to DU4-DU7 (this is with a handler without the extended unit support, of course). >Also I assume that a partition has to be 65,535 blocks, but does the last >one have to be that, or will it simply be however much space is left? It is automatic. All partitions other than the final one will be 65536 (not 65535) blocks in size. The last one will be whatever is leftover (total_size % 65536). BTW - although the partitions are 65536 blocks in size, the last block is reserved, so the effective size is 65535.

No, I only soaked them for about an hour. They quickly reached a point where no more oxide will come off with a foam-type "q-tip". Still, there is so much oxide left that won't come off...

14" hard drive refurb....

by jlwest＠tseinc.com

Sorry Allison, I meant to say the head was heavily coated with oxide from the disk platter, not oxidized itself! :) I just removed the two lower heads, and neither comes clean with 91% alcohol. Now I'm just soaking the heads in a glass in the alcohol, and waiting overnight to see if they'll then come clean. If that fails, I was wondering about a toothbrush with just 91% alcohol.

DSSI in a BA123?

by cmcmanis＠mcmanis.com

Ok, this is the challenge. NetBSD runs flawlessly on my KFQSA in the 3900 but hangs using the SIGMA RQ11D in my uVax 3. Since I have an "extra" KFQSA (now knowing how to configure it!) I could put it into my BA123 but that appears to be a challenge when no documentation is present :-) Some questions: 1) The Controler <-> drive cable, can I crimp a three appropriately sexed IDC connectors on to flat ribbon cables for hookup? 2) How to hook up the drive control panel? The 3900 has a connector that is wired to the bulkhead and the drive, it also holds a "unit number" plug. The BA123 has its normal DRIVE 0 WP/Ready control with a different sized connector. Can I adapt it to the RF7x series drive? How? 3) DSSI terminators connect to the scsi like DSSI connector, if I put a SCSI 2 connector on my cable can I use an active SCSI 2 terminator instead? As always, thanks! --Chuck
