WinSystems LPM/MPM 7109 card? was Re: New Finds Today

by dwight.elvey＠amd.com

Hi Joe The 7109 was made by many manufactures and is a common A/D. It is a dual slope type. Quite accurate when comparing to a reference. It has one funny feature that isn't usually mentioned in the data sheets. If you get an over range, it will transfer some additional energy to the Auto-Zero capacitor. This can take many convertion cycles to recover from. When used with an input mux, make sure that you either have a wait after overrange or some way to clamp it below full scale. Even a single lsb of overscale has significant effect because of the amplification used to do the auto-zero. A single lsb of overscale can be over 100 lsb's on the next read, depending on the A-Z capacitor size. Not good when you are looking to get the most out of the 12 bits. As for the board, maybe just some tracing out will determine the addressing so that you can play with it. I have a 80C188 processor board for the STD with a Forth in Flash on it. I find Forth to be real handy for poking ( and peeking ) at unknown boards such as these.

WinSystems LPM/MPM 7109 card? was Re: New Finds Today

Yesterday I picked up two shoebox sized units that were marked as "enviromental units". However they had lights marked Tx, Rx, etc and a Comm port. Inside it had a STD bus chassis with three cards installed. On has a 80C31 CPU, one has a Zilog Z0853004 comm chip and the other has a MAXIM ICL7109CPL A/D convertor. The first two cards appear to be custom made and are probably useless for anything except the system they were designed for. However the third card (with A/D) is a standard commercail product and was made by WinSystems and is their model LPM/MCM-7109. Does anyone have any data on this card? It's not on WinSystems website and I tried to contact them and ask about it but they were less than cooperative. Joe

New Finds Today

by rigdonj＠cfl.rr.com

Went scrounging today and found a BIG pile of computers. MANY Dell PCs and a lot of IBM Power PCs. Brought home some of the PCs to check out and found that they all have P-III CPUs and ranged from 500 to 866 MHz. Some even had CD-RW drives! More interesting finds included two HP 9836Cs (the color version of the 9836), a HP 9000 380 (Probably top of the line for the HP 9000 200/300 series), a Sun Ultra 1 Creator 3D, a >>Hyundai<< Sparc model HWS-S310 (I had no idea Hyundai built andything like this!), a Matrox Shark 10/100/FX Ethernet switch, a SUN SparcStation 20, a HP drive array with hotswap drives, and one old PC with a very strange looking card in it. I'm going back tomorrow and pulling parts from the PCs that I didn't take. They're all going to a steel scrapper so I'm free to take anything that I want from them. Joe

MS BASIC for a Panasonic HHC RL-H1400

by martinm＠allwest.net

I have accumulated a couple of Panasonic HHC RL-H1400 "Hand Held Computer"s. For a description, see: http://members.cox.net/obsoletetechnology/Panasonic_HHC.html Searching has indicated that a ROM "capsule" containing a version of MicroSoft BASIC was available. Does anyone have one of these capsules, or a dump of a ROM that can be written to a new ROM? The computers that I have came from insurance agents and have insurance software on the ROMs that came with the computers. The insurance ROMs are Motorola MCM 68764C and appear to be UVEPROMs. Thank you, Martin Marshall

Now I know these are AUI cables. Useful. As Paul pointed out, there were other colours -- they just happen to be very rare here, and I've only ever seen blue ones. However, some of those blue ones weren't PVC, so perhaps they're low smoke/no fume (LSOF). I've also got at least two types of thick ether cable, but both are yellow. And several types of thinnet, including yellow and grey as well as the more common black. As Paul and der Mouse suggested, I agree that it would be worth making up a short flexible AUI cable. Cat 5 is 100-ohm, and ribbon cable is not far off that IIRC; you could use STP instead of UTP to get the shield (some Sun cables are STP), or just ignore it for really a short (a few inches) cable. Or a chunk of old good-quality serial cable should do a good job over short distances, I expect. -- Pete Peter Turnbull Network Manager University of York

According to the standard, the markings are supposed to be on all 10base5 cable; they're to indicate where it's safe to put a transceiver, and where to cut the cable at the ends. They're every 2.5 metres, and there should be at least two between transceivers. However, I've seen cable that didn't have the bands, but it was probably ordinary coax rather than intended specifically for ethernet. -- Pete Peter Turnbull Network Manager University of York

Not only do CRTs not discharge naturally (unless they're in circuit with a bleed resistor), a disconnected and supposedly-discharged CRT may develop a charge if left alone. The original EHT can force electrons into the glass, and since glass is an excellent insulator, they don't come out again immediately when you discharge the tube. They *may* come to the surface slowly later, and give the CRT a significant charge of opposite to the original polarity. So leave a bleed resistor across a tube you plan to store for a long period (tip given to me by a TV repairman). If you're discharging a recently-used tube, don't use a simple resistor. The EHT on a CRT could be anything from 8kV to several tens of kV in a fancy colour tube, and most common resistors have a breakdown voltage of only 500-1000V. Besides, think about the power dissipation if you discharge a 25kV tube through a 10M resistor: 2.5 milliamps, but 62 watts. Sure, that 62W won't last long, but neither the tube nor your resistor will like it! -- Pete Peter Turnbull Network Manager University of York

It might just be doable with an office-grade cable. They tend to be thinner and more flexible than the proper thick blue ones. Or you could remove the cover and fit a right-angle cover, probably. You could certainly do that with an office-grade cable -- I used to have one like that. I seem to remember having a genuine DEC beige transceiver, about twice the size of the minature Allied Telesyn ones that are so common, which had the AUI connector on the side instead of the end. -- Pete Peter Turnbull Network Manager University of York

Queries to group

Hi Ok, this is just too much of a coincidence. We just got 5 post that were queries about post to our group. Only one of the post recognized that they were sending to a group.

New Finds

by marvin＠rain.org

As quite a few people are aware, I tend to *really* like documentation and books. Today was a good day for that as I acquired part of the library from someone who had died a few years ago and was into computers. The computer related books ranged from the 50's to the early 80's. A couple of books I had not seen but look to be very interesting are: The Computer from Pascal to von Neumann - Goldstine The Analytical Engine - Bernstein Sequential Machine: Selected Papers - Moore There were quite a few books on software design, digital hardware design, analog and hybrid computer design, compter logical design, operating systems (including Tanenbaum), etc. This is enough to keep me busy for a while checking them out :). Unfortunately, an H-89 had already been recycled but there is still the possibility that the manuals, etc. are still around. After I cull out the books I want, I'll list them on the Computer Marketplace.

Hello Paul, just to enable all readers to understand I'll answer in English. The "RCD" (say Dutch Radio Control Service) has changed their policy since Sept, 1st, 2003. You can get -if still available- within some restrictions (depends on the license) the call you like (for $$$). I had the C license, and wanted to "upgrade" from PE1CKF to PE1PDP, but I was studying for the morse exam. I passed the very last morse code exam last December, and changed the prefix also to reflect the A license that I now hold. For insiders: I hope to be QRV on HF in a few months, and what that makes special is that I use equipment from RACAL, no Japanese toys! What is RACAL?

TRS-80 Model 12 crt substitution - Now I need help with 8" drives

by redodd＠comcast.net

Thanks to all who replied to the crt problem. The crt from the TRS-80 Model 4 was a perfect replacement for the Model 12. Now I have 2 - 8" Tandon thinline TM848E dsdd drives that have problems (in the Model 12). Drive 0 (lets call it A) used to work fine but now all it does is blink (the red busy led). 3 blinks followed by 1 blink or maybe it's 1 blink followed by 3 blinks, hard to tell. Drive 1 (call it B) always made noise and wasn't as reliable as A. I took A out, made B drive 0 and installed the resistor pack. Now B won't boot, I get to "initializing" and then I get a seek error. I have an original TRSDOS 2.0b disk and a copy and both used to work. Both get the same error. The drives have what I am going to call a logic board that's easy to remove. It has the drive and power connectors on it. I've tried every combination of mixing drives and logic boards but I still get the same errors. Does this blinking make sense to anyone and can I cure the seek errors on the other drive? Thanks again for listening to my ranting. Ralph

Not hard to diagnose or replace, but I wonder if that's a common failure? Another one had a bad filter cap -- but it had died of age (leaked) rather than causing a short. Another common "problem" seems to be whistling from the coil, if it's begun to delaminate. Probably a sign of previously running hot, and not necessarily anything to worry about. Several of my "brick" PSUs had faulty bulbs, and I found the easiest way to fix that ws to replace the bulb with an LED and a resistor, as found on the later versions. -- Pete Peter Turnbull Network Manager University of York

86/330 Problem(s)

by hirschopd＠msn.com

Joe, We solved the hardware portion of our problem and are now trying to resolve some iRMX system issues. How do I get availability and price on some of the Intel Manuels included in your list and that of Alossow's.

Elektor and OSI's OS-65D (was OHIO-DOS)

by RMaxwell＠atlantissi.com

As the owner of a modified and still-working OSI Superboard 2 running under OS-65D 3.3, I may have a few insights about the Elektor link to OS-65D: - I had owned my machine for around 5 years (that would make it 1985) when a friend showed me the two-part Elektor article of a floppy-disk interface for the ongoing "Junior Computer" series. Using the schematics, I hand-wired (anyone else remember Vector's "Pencil Wiring" with solder-through insulation?) a disk interface for my Superboard. - The Elektor article "adopted" OS-65D because OSI sold the DOS as a stand-alone product, complete with utilities for customizing disks, developing code in BASIC and Assembler, and capable of running serial or memory-mapped user I/O with the change of a byte in DOS. It sounds like the Elektor authors went forward and used OD-65D for later projects. - By 1985, MA/COM had renamed OSI to ISOTRON during the slow- and shut-down of manufacturing - they stopped buying masked ROMs, and made Superboards and C1Ps patched to use 2716 EPROMs instead - but were still selling the Disk OS. When I telephone-ordered a copy and asked for "OS-65D V. 3.3 for a C1P", a fellow worker figured I was some sort of spy speaking code! Fortunately, the folks at the factory knew what I was talking about. The documentation binder bears the name ISOTRON on its cover. - Like the Elektor authors, I patched my OS-65D, for an 80x24 video card in my system. I had written extensions into a copy of the OSI Monitor ROM: I was a little peeved when OS-65D loaded, ignored the redirected video, and brought in its own drivers for the original 24x24 screen... I was sooo glad I maintained back-compatibility. I still have the original OSI disks and docs: there are 5 disks with all sorts of utilities (mostly in BASIC), the binder for the OS and separate manuals for the "Assembler/Editor and Extended Monitor" and disk BASIC. The handiest thing (and most well-worn!) is the little fold-out card listing DOS commands, memory locations and error code descriptions. I'm a little puzzled at the reference to OS-65D V3.2... Version 3.3 was the "full" version, and the single-floppy reduced version was 3.1: perhaps someone patched a version 3.1 disk for their own project, and just incremented the number?

Brother Wordprocessor Floppy Disks

by tlindner＠ix.netcom.com

Yesterday my boss came to me and handed me a stack of 3 1/2 inch floppy disks and asked me to get the data off them. Ahh, the perils of being the geekiest person in your orginazation! :) Anyway, all he could tell me is that they were from a Brother word processor. It didn't have a model number and no serial port. One of the disks is a system disk ("Spreadsheet, punctualtion alert and data storage disk for Brother Word Processor version <1.0>") and is dated 1991. I tried the disk in my DOS 6.22 PC, no deal. Then I tried cw2dmk (thanks Tim!) and my Catweasel, but I guess the format isn't close enough to IBM 370 (FM) or IBM 34 (MFM) formats to be useful. Does anyone know of a tool I can use to read these disks? Barring that: does anybody know what format the disk is using? I'm not past modifying cw2dmk to read it, but I would hope not to have to reverse engineer the "on disk" format. Thanks! -- tim lindner tlindner(a)ix.netcom.com

H744 +5 supply - easy to fix?

It's used in various devices, from KL10s to 11/34s so the schematic shouldn't be hard to find, and yes, they're fairly easy to work on. It's a fairly simple circuit based on a 723 regulator chip. I think I do have a spare, but I doubt if you want to pay transatlantic shipping :-) H7440 and H7441 are very similar (different circuits, same purpose). -- Pete Peter Turnbull Network Manager University of York

atc-510 simulator

by mwallin＠cinci.rr.com

Doug- hello, not to be a pest, but I was about to list some accessories for my old atc-510 flight simulator on ebay. I searched the internet for atc-510 simulator, and only came up with a handful of results. One of them was a thread where you said you were looking for something for your 510. Please let me know 1) if you still have the unit and 2) if you are looking for any accessories. thanks for your time and sorry to bother you, Mike

Saved (big haul)

by waltje＠pdp11.nl

Hi all, Thanks to Andreas Holz and Mr. Howard Israel of Zetters Pools Ltd in London, we managed to save three PDP-11/94's, two 11/44's and a /24, plus RL02 disks, a zillion spares, a lot of documentation and small stuff. All systems were SCSI based, so, yes, we're VERY happy with them!

Good morning. I came upon your email address while doing a google search for information on the Heathkit ES-400. You had posted an inquiry asking if anyone knew how many ES-400s had been made or sold. Wondering what you found out? An ES-400 recently turned up at a museum in Minneapolis.

Linux Box + DOS 3.2 box + (1)5.25 floppy drive (okidata 3305BU) = HELP!!!!!!!!

by lyosnorezel＠yahoo.com

Hey y'all... I need some help. I recently acquired a Compaq Portable(ye right... at 35LBS no one is crazy enough to carry this machine around) II... with a hard drive and a 5.25 floppy disk drive. The hard drive apparently has MSDOS 3.2 and some Novell application. When booted up it first checks the memory then it checks active partions... then it starts going in some kinda loop looking for a file server that isn't there. I don't have any other 5.25 floppy drives so I am unable to create disks to transfer files to this box. I was wondering if it was possible to connect the floppy drive to my linux box and copy the files to the disk(s) from there and retransfer the drive to the compaq to use. Problem is that the Linux box is an RH9 platform on a PII (686) system. Would RH9 even have the needed drivers for a drive this ancient? Can this be done or am I, for all intensive purposes, screwed?
