< <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

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!

Which brings up the question, >is there any harm in not using all the space on a Hard Drive when you >have it partitioned with RT-11? I don't care that I can't use the space. 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). If you only run distributed software or your own code, there will be no problem (modulo any bugs that might be lurking).

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

Available Documentation, Parts, and Computers - part 1

by ware＠interaccess.com

Moving day is quickly approaching, and I need to trim my collection down quite a bit. I'll be going through the majority of the hardware this weekend and posting a more complete list of available items then. Until then, I have the following items (some of which I'm sure I'll eventually kick myself for getting rid of) available. To keep things simple, I've included enough to cover shipping costs in the continental US in these prices. Feel free to make other offers if these prices seem out of line - I'm really only looking to recoup some of the cost of packing and shipping things out during a period when free time is at a premium. AT&T UNIX PC / 3B1 software and documentation - Complete copy of SYSV UNIX version 3.51 for the 3B1/UNIXPC. Includes all manuals. Shrinkwrapped. $15. Apple III "BPI General Accounting" and "BPI Accounts Receivable". Boxed, with docs. Requires ProFile. $20 for both. IBM OS/2 2.1 "For Windows". Shrinkwrapped. Several copies - $10/each. Control Data 9427H Disk Drive service manual - $5 IBM XENIX documentation - Assembler reference, text formatting guide, software command reference, library function and C reference - $15 for all. AT&T PC6300 User's Guide - $5 Coleco ADAM Logo manual - $5 Radofin Aquarius - includes PSU, missing cartridge port cover - $10 TRS-80 CoCo2 - OK physical condition, untested - $10 Coleco Adam - System unit, printer, keyboard. System worked when last used, printer non-functional, printer PSU good - $40 Magnavox RGB display 80 - Analog RGB (Amiga), digital RGB(CGA), and NTSC composite inputs. No cover for controls - $40 Mono composite monitors - Apple, others - $15 Nortel ISDN terminal adaptors - 64k sync / 57.6k async operation on one B channel. Requires external NT1. 2 units, one psu, one manual - $20 Apple Disk II drives - untested - 2 for $15 3 Magnavox Odyssey pong systems - red, yellow, and white (200,300,400?). One AC adaptor, one RF connector. $40 for all Magnavox Odyssey2 - Boxed, with joysticks.

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.

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

EMC buys Data General

by cmcmanis＠freegate.com

Another classic computer maker "bites" the dust. See: http://www.news.com/News/Item/0,4,40250,00.html Which is a news.com story about how EMC (makers of storage products mostly) will buy Data General for 1.1 billion in stock. This was the last of the great mini-computer companies that had been left standing after DEC was bought by Compaq. I'm looking for other examples, but I believe this leaves IBM (System 360) and Sun (SPARC) as the last two companies who designed their own computer architecture still standing under their own name. (I don't count Xerox since they don't sell their D-series machines any more). Companies known to have gone away: DEC Data General Tandem Prime --Chuck

NO! Try a Qtip with some acetone (nail polish remover) and then clean that off with isopropanal. There are plenty of more aggresive cleaners before resorting to abrasives. When my RL02 crashed (bad pack) I had to use MEK on the heads to get them clean. Isopropanal or ethanol are about the most mild solvents and someof the media binders need some push. Allison

Stuff available in Richardson, Texas

by dastar＠ncal.verio.com

A company in Richardson, Texas wants to get rid of some fairly classic stuff. I've personally seen all this stuff, but it was almost two months ago and I've forgotten what a lot of it is. However, if you have a question about anything, please e-mail me and I'll try to get it answered for you. The price for this stuff is open ended. My guess is that in most cases they will want some token amount, or may even be happy for you to come and take it away. I'll act as the go-between so any offers you want to make should be mailed to me and I'll forward them on for you. Please include an e-mail address and a telephone number.

Tektronix 4634 hard copy unit

by Innfogra＠aol.com

My 1984 catalog indicates that it processes video signals, both analogue and digital. It appears, from the cables offered that the analog is a 75 ohm BNC and the digital is a 15 pin, prob. D sub Centronics type. Nothing indicates that it could be used with the 4051, also in this catalog. It's recording technique processes raster scan video with a fiber optic CRT. It does use both kinds of Tek dry silver paper, switch selectable. The High performance paper 7772 is capable of 125 lines per inch(LPI). The regular 7770 paper does 100 LPI. There is a RGB Mixer available for color to mono conversion. I may have a new one in a box if you get the 4634. The printer, new, comes with a roll of paper, 75 ohm terminator and manual. If it is new in the box I sure would recommend getting it. Few of these exist because they are valuable as scrap metal. In 1984 Tek wanted $7900 for this printer. A roll of paper cost $215, a case $750. If your Tek 4051 has a 15 pin video out in the back it might hook up to this printer. The connector on the printer is not a Tek GPIB port. Paxton

VCF hotel room block now available

by dastar＠ncal.verio.com

I just secured a block of 20 rooms at the Biltmore Hotel and Suites in Santa Clara for VCF 3.0. This is the same hotel we used last year, and they were very good to us. The room rate is $69 or $89 a night depending on how much you want to spend. I stayed a night in each room (the regular rooms and the tower suites) last year and both were comfortable and clean (of course the tower suites were much nicer :) $69 a night for a room in Santa Clara is a prtty damn good deal actually. All the information you would need to reserve a room can be found at: http://www.vintage.org/vcf/hotel.htm Act soon. The deadline to register at the VCF rate is September 3. Be sure to ask for the Vintage Computer Festival room rate. If you have trouble you can probably ask for Sabina, whom I negotiated with. Please e-mail me as well if you do.

Are tatty boxes worth keeping?

by dcoward＠pressstart.com

Various people said: >> > The Commodore 64 _could_ run CP/M programs...provided one had the >> > optional Z80 cartridge...though I never tried myself. :-) The 128 was the >> > first Commodore machine to actually boot CP/M disks with a 1571 drive, if I >> > remember correctly. >> >> Well so _could_ the PDP-8 if someone built the necessary hardware or wrote >> a simulator for it :) > >And so can a Macintosh if you run a terminal emulator and connect the >serial port to a Northstar Horizon. :-) I point is that Commodore had the foresight to put a "DMA" line on the Expansion Port so that an external device could tri-state the address lines on the 6510, effectively removing the 6510 from the memory map. Which makes it very easy to run the C64 with multiple processors or just a different processor. The C64 CP/M cartridge was set-up so that you could have 6502 code embedded in your Z80 code. You just need to set a certain register every time you wanted to switch processors. That coupled with the fact that you could swap out all the ROM and all of the I/O leaving a continue 64K ram space, makes the C64 a hardware hacker's dream. Just my two cents. --Doug =================================================== Doug Coward dcoward(a)pressstart.com (work) Sr Software Engineer mranalog(a)home.com (home) Press Start Inc. http://www.pressstart.com Sunnyvale,CA Visit the new Analog Computer Museum and History Center at http://www.best.com/~dcoward/analog ===================================================

14" hard drive refurbish question (7900A)

by jlwest＠tseinc.com

I finally got around to putting a new lower platter into my 7900A. Kinda hard to do from underneath, but it's done. Now I'm getting ready to take the lower heads out for thorough cleaning. Before I do, I wanted to ask some advice... When I powered the drive up before, I could hear minor HDI (very slight scraping). Upon inspection it was obviously the lower platter that was missing a track of oxide. The heads had oxide on them but they didn't look all that bad to me. Most of the folks on the list (and a few people I talked to voice) said just replace the lower platter and clean the bottom heads and all would probably be well. Two questions: 1) Everyone said because the lower platter is fixed, there's no concern for alignment, precision, feeler guages, etc. Just unbolt the heads, clean 'em, and bolt 'em back on. No special checks and so forth. Before I unbolt them I wanted to double check and make sure I wasn't about to do anything silly. So - just unbolt, remove, clean, rebolt, and power up? 2) I was thinking (bad sign <grin>)...if the heads contacted the platter enough to scrape off a nice circle of oxide, won't cleaning the heads and replacing the platter accomplish nothing? What I mean is - isn't it very likely that whatever caused them to scrape in the first place won't be fixed by a new lower platter and cleaned heads? What am I missing here? Thanks in advance for the education on 14" hard discs! Jay West

MsWorks for DOS?

by roblwill＠usaor.net

Hi! I was wondering if anyone had an old copy of MS-Works (3.0?) for DOS that they'd be willing to email to me trade something for (I have some old Mac and IBM programs). I'm looking for a copy of the install disks to install in an old ZDS SuperSport. The JVC HD recently seized in it, and I bought a new one (Alps) through www.zdsparts.com . Luckily, I had all of my documents backed up on disk, but unfortunately, the MS-Works that was on the Zenith was the only copy of MS-Works I have, and it was on there when I bought the computer. I'm currently using WordPerfect 5.0, which doesn't recognize Works format, or have spreadsheet / database. I also really don't feel like spending the money to buy a new version of Works to just convert the files to WordPerfect. (Word '97 doesn't read Works 3.0 for DOS format files, either.)

Tektronix 4051 or 4052

by mmcgraw74＠hotmail.com

I bought a Tek4051 while in the USAF in 1978. I developed several programs using the 4051 for data collection and reduction. I would like to find one, probably for the nostalgia, I still have the my old program listings. I saw the recent thread on the EXEC command, I figured out the EXEC command and wrote a couple of 6800 assembly language programs (play music, dump the ROMs to the printer, etc). As I recall the format of the command was EXEC A$, where the string was typically read from the tape as a single file.

Information on part

by edick＠idcomm.com

The WD2797 has little in common with the i8272. It is essentially a WD1793 with a built-in PLL for clock recovery. The instructions are, I think, the same as those for the WD1793. The clock recovery circuit works adequately for data rates suitable for 5.25" drives, but is less than wonderful for the 8" drives. It was used with great success on the 5.25" drive interfaces on Western Digital's line of bridge controllers. AFAIK, it was not as well received as the 9229 and 9216, both of which were digital clock recovery circuits suitable for use with 8" drives. These were popular enough, however, that someone on the list probably has already scanned the data sheet.

Stuff in Richardson, Texas followup

by dastar＠ncal.verio.com

Ok, I spoke to the employee handling the purge of obsolete equipment at the company in Richardson, Texas. Here's the deal: they would prefer if someone could just come and haul all the crap away and be done with it. They don't want anything for it, just for it to be hauled away. More has been added to the pile since the list I posted, but I don't know what. I'm going to probably be in the Dallas area at the end of this month or beginning of September for probably the last time in the forseeable future. I may make one visit or two or maybe even several, I don't know. But, the point is that I can make arrangements with anyone in that area who wants to meet me at the company and haul the crap away. Then you can do what you please with the stuff. Sell it at a profit to others, be nice and give it away for 1.2*shipping, etc. So I put out the call to anyone in the Dallas region who is interested in taking this on to e-mail me and figure out what to do with this stuff. To those who have expressed an interest so far in some of the stuff, I'll e-mail you separately about what happens next.

The first time you spin it up I would unplug the head positioner and let it spin for 10 minutes without the heads loading to be sure to get the last of the dust out. I don't know if the HP will stay spinning if it does not find a servo track however. If it doesn't then spin it up and down several times before allowing the heads to load. What you have done along with above comments are all I ever used to do. Dan

The reason we could support 20+ users on the VAX with 8Mb of memory was a) the 32-bit channel to disk and b) DMA outbound serial I/O (a wad of Emulex 16-port muxes).

In general, Tony, I agree with Sam. The packaging can provide insight into both the packaging technology of the times and the marketing strategy (some of the claims on those old boxes are outrageous, and the graphics can be interesting, too!). Additionally, collectors will certainly pay a premium for an item which includes some or all of the original peripheral "trash." The foam does tend to break down, especially if it is in contact with other plastic items such as cables, etc, but it is still worth keeping. My solution is to wrap the foam -- and each item it contains -- in _stable_ plastic bags, and then stash the whole mess in a larger cardboard box. This of course requires a certain abundancy of storage space . . . Glen Goodwin 0/0

The Z-80 cart was originally shelved when Commodore decided it was taking too much time and engineering effort to develop. The FTC forced Commodore to produce the carts or be sued big time. They produced enough to satisfy the FTC requirements, and that was the end of that. CPM carts are quite scarce as a result. (And a bit buggy).

Spiffy Little Hamfest Find

by edick＠idcomm.com

The supply connections on the schematic are +24, +12 , +5, Gnd, and -12. The +24 is shown with a separate return from that of the other supplies. It seems to me that there is a considerable tolerance on the +24, but that's a common supply voltage. The thermal printer appears to be a TI EPN-9120, which might be just as happy with 18 volts, but might require a different set of passives at that voltage. I doubt you'll hurt anything with a voltage as low as 18Vdc, though the stepper may want more. When I used this mechanism, I usually AC-coupled the stepper so the circuitry didn't heat when the printer was idle. All indications are that the AIM uses a couple of parallel port bits to provide the ultra-slow (110 bps) interface to the TTY via some transistors and TTL gates. It's not the usual isolated 20mA interface. However, TXD is on J1/pin U and its return is on S, while the RXD from the TTY KEYBOARD and its return are on J1, pins T and R, respectively. If you want to improve anything at all, I'd start by combining the input clock with the R/nW signal to create the write strobe to the RAM memories. That will provide considerably better hold time, which 2114's definitely require. I normally 'NAND' the Phase-0 and Phase-2 clocks with inverted R/nW to accomplish this. There's a single-step switch and a reset switch, as well as the one that selects the TTY keyboard. I wouldn't be afraid to "play" with this one. It looks like it can handle reasonable abuse.

IBM Laptop Keyboards

by danburrows＠mindspring.com

The local Hospice organization is having their annual flea market. One of the workers pulled me aside and asked if I knew anyone that could use a box of 16 brand new replacement keyboards for IBM laptops. Neither of us know what model they are for. He gave them to me to sell as they would have been dumpstered. If anyone is interested please contact me off list for shipping etc info. I will be asking for 2 checks. One to Hospice and one to me for actual shipping costs. The one to Hospice is for what you feel they are worth. Keep in mind they are a non profit organization and the flea market is how they raise funds for the local home. The IBM P/N 07G1103 FRO P/N 07G1735 EC No. C81240 Then under the bar code is *1M630037331 They do not have the pointer nub in the middle of the keyboard so I know they are for an older model. Might even meet the 10 year rule.:) FWIW almost all of the PC related stuff that I get in the course of my business gets donated to Hospice for this annual flea market. Dan

Tektronix 4634 hard copy unit

by rigdonj＠intellistar.net

Hi, Is anyone familar with this unit? I know what it is, it's a screen printer. I have a catalog that describes an earlier model but not the 4634. Does anyone know if this one also requires the dry silver paper? Will it work with the Tektronix 4051 computer? Exactly how are these connected to the system? I found one of these in a junk yard. It's still new in box. I'm wondering if I should grab it to add to my Tek 4051. Joe

OT: Power Supply voltage for Dayna Etherprint-T plus? (resolution)

by mtapley＠swri.edu

Anybody who started with this thread (and many thanks to Mike Ford), I got a second hand wall-wart power supply which puts out 9v dc 500 mA. The connector on the wall-wart cable has a socket for a central pin and an outer conductive barrel. The socket is +, the outer barrel is - according to the power supply label. I plugged it into the Etherprint-T Plus and it ran fine for at least 5 minutes (after which I unplugged it and went to bed). I'll let you know if it causes trouble later. YMMV, of course, but as far as I can tell Mike's forwarded post took care of me perfectly. Thanks, Mike! - Mark

Anyone else? Sounds like a externally mounted TK50 for use with the usual Qbus M7546. The companion was the externally mounted RD5x for use with the RQDXn and the matching distribution card. Both are for those that had BA23s and no place left for a disk or tape. Allison

tek4113 available.

by jritorto＠nut.net

Hello List, Would anyone like a Tektronics 4113 graphics terminal? It's in perfect working order, but slightly scuffed here and there. One 8" floppy drive that works, color monitor that works, and perhaps even the color printer that goes with it, though I haven't seen that thing recently. I'm looking for pdp11 stuff, a sun3 framebuffer, cash or a good sob story in exchange. It's near Pittsburgh, PA. and it's pretty big, so you'll probably not want to mess with shipping.. Act fast before I shamelessly pimp it on Ebay... jake

Spiffy Little Hamfest Find

by edick＠idcomm.com

Forgot to mention, I have a bit of DOC, but haven't read it yet. Perhaps I can find where the serial port connections are located. Since the thing doesn't appear to have a UART, I'm curious what it uses. Perhaps it uses a 6522 serial I/O port. It could bit-bang, I guess. After I've looked the docs/schematics over, I'll know more, which I'll share, if needed.

Spiffy Little Hamfest Find

by edick＠idcomm.com

The plastic cases were an add-on, but the printer and "funky" LED display were standard. It's a standard sort of 6502 board, with a 1 MHz processor, a bit of ram and a bit of ROM, depending on what you put in. I've got two of them (borrowed) atthe moment, one with a video board and extra prom board and a prom programmer, and the other without the case, etc, but with all available ram and rom populated. I believe it's got the assembler and BASIC in ROM along with a monitor. AFAIK, there's a FORTH available for it as well, but I'm not a 4th sort of guy. Joe Rigdon has a couple of these with the BASIC and Assembler ROMs on board. Maybe you want to pull his chain and see what's really in those ROMs he's got.

From: "r. 'bear' stricklin" <red(a)bears.org> > Is a TK50-D not a SCSI device? It sure bears only about a fifth of a > superficial resemblance to one. > If not what is it used with? The -FA and -GA models have a SCSI controller board (TZK50) with the drive, in the box which is about 12.5 inch (32 cm) wide. Assuming that the "-D" is the one which is about two-thirds as wide, it is just the raw drive with its ribbon cable going to a (largely idle) 50-pin D connector (as I recall). It connects to a suitable controler, such as the Q-bus TQK50 or the UNIBUS TUK50. I believe that it was most commonly used with big-old UNIBUS machines like the VAX-11/7xx, which had no convenient place for an internally mounted TK50 drive, whereas most Q-bus systems did. Nowadays, the most common use for one is probably as a safe place to keep a spare drive, in case the drive in one's -FA or -GA fails. ------------------------------------------------------------------------ Steven M.
