TRS-80 Model I Computers

by alhartman＠yahoo.com

The presence or lack of a numeric keypad on a Model I is not a good indicator of whether it's Level I basic or not. I have a Model I (My original from 1979) which came without a keypad, and was a Level I computer, but which I quickly upgraded to a Level II computer. The only real way to tell is to power the unit up. Regards, Al Hartman P.S.: I'm looking for a working LNW-80 Computer. A model II would be preferred, but a Model I would be OK.

S100 spares needed - repairs almost done

by labomb＠rochester.rr.com

To clarify a bit ... Don's disks work perfectly with the DD controller ... and with the N* base system itself (post overhaul). However, when I swap out the controller for an SD iteration (tried two actually) ... no joy. While the boot drive does indeed enable, I can hear that no sectors are actually getting read. I'm not positive, but I believe that the N* software (both DOS and CP/M) changed quite a bit with the advent of the DD controller, as did the firmware bootstrap. And while the DD controller can read and format SD disks ...I don't think that it can create bootable disks that work with the older SD controllers. Haven't tried it myself yet ... Scott

Here is some info from the manual (EK-VR320-IN-001): Resolution Frequencies Model Horiz Vert Horiz - Khz Vert - Hz -------- ------ ---- ----------- --------- VR320-CA 1280 x 1024 70.66 66.47 * VR320-DA 1280 x 1024 77.13 72.56 * * The VR320 manual states that the monitor can operate at either 66 or 72 Hz, and is preset to match the machine prior to shipping. The manual also says to contact DEC Customer Service (yeah, right) if a change is needed. If DEC set it to 66 Hz they stamped 'CA' after 'VR320-' on the ID tag, if set to 72 Hz they stamped 'DA'. DEC set it to 66 or 72 Hz using a slide switch that is inside the monitor. The switch is clearly marked 66 & 72 Hz, just set it to the desired position. Here is the details in case you decide to pop for the video card. VR320-CA VRT320-DA Pixel Clock: 119.84 Mhz 130.81 Mhz Pixel Period: 8.34 ns 7.64 ns Horizonital Pixels Horiz Freq: 70.66 Khz 77.13 Khz Horizontal Period: 14.15 us 1696 12.97 us Active Video: 10.68 us 1280 9.79 us Blanking Interval: 3.47 us 416 3.18 us Front Porch: 267 ns 32 245 ns Sync Pulse: 1340 ns 160 1220 ns Back Porch: 1870 ns 224 171 ns Vertical Lines Vert Freq: 66.47 Hz 72.56 Hz Vertical Period: 15.035 ms 1063 13.7824 ms Active Video: 14.49 ms 1024 13.28 ms Blanking Interval: 552 us 39 506 us Front Porch: 42.46 us 3 38.89 us Sync Pulse: 42.46 us 3 38.89 us Back Porch: 467 us 33 427.9 us I don't know the outputs of the RB or the 150, so can't say it will work or not. By the way, the VR320 will work with some display cards used in the DECstation 5000. I do have a spare copy of the VR320 manual and you can have it if you want it. Send me a private email with your mailing address. Hope this helps, Mike Thompson

Woohoo! What a find!

by avickers＠solutionengineers.com

Today, I picked up (for just the cost of petrol getting there :) a Mator Shark hard-drive for CBM PETs. All 22meg of it! And it WORKS! Sounds like a jet engine when you turn it on, and it's about the size of Texas, but waaay cool :) Also got a flakey 3032 - I think there's a ROM problem, as it displays a line from the monitor (debug monitor, that is) with a wildly-flashing cursor, and no k/b input accepted. Of course, the latter may be due to just a dodgy keyboard, so this one looks like a bit of a project job. Plus assorted other gubbins, some of which is probably too new for this n/g (Amiga, +4, a 4030 floppy drive, 3 printers, an Amiga HDD & C64 serial->IEEE488 i/f box). Ho boy, am I in 7th heaven right now :) -- Cheers, Ade. Be where it's at, B-Racing! http://b-racing.com

S100 spares needed - repairs almost done

by rcini＠optonline.net

Hello, all: Scott has made much progress in repairing my N* machine. Well, calling it a N* is a stretch since the only thing N* about it is the motherboard, case and disk controller. Anyway, I'm having diskette issues. I have two theoretically good single-density controllers and disk drives, and Don Maslin made replacement boot disks for me. These disks don't boot, although the controller attempts to access them. It may be that the replacement SD disks were made from a DD controller, but I don't know for sure. So, I have two choices -- obtain SD boot diskettes made with an SD controller or get a N* DD controller (MDS-AD|AD2|AD3). Any other thoughts or recommendations appreciated. Thanks.

If you're up for paying duties on around 70% of *new acquisition cost*, backed up by *the original (NOT a copy) manufacturers invoice* -OR- the right amount of discrete 'speed money' to the right person (you hope), which 'speed money' will be a substantial fraction of the original duties, and *then* you pay the re-crating (because the customs guys tear this stuff apart and then throw everything back in what's left of your box and some guy from the villages comes and slops 3 feet of cheap tape on it... and then you pay the actual shipping... *then* you deal with customs here in the US... AND you pretty much need to be there to take care of the little 'derailments' as they continually arise. Doing this long distance with no representative there, would be impossible.

COS-300 and DMS-500

In case you > didn't know, COS-300 is RT-11 with DIBOL layered on it or something.. > COS-500 is the same but its RSTS-based if I remember correctly.. > What makes COS-300 hard to find is that most distributions were on RK05s, DEC's low end 2.5MB front load cartridge hard drive. These were not the most durable of drives and often succumbed to head crashes. However, it was relatively easy to replace the heads, about an hour's work for field service. COS-300 (Commercial Operating System 300) was an OEM package VARs sold to small businesses in the 70's. A typical system was a smaller PDP, an 11/34 or 11/03, RT-11, and the DIBOL compiler, along with something added by the VAR. There were several basic financial packages for the systems, GL/AP/AR/PY or accountant client write-up being typical markets. Your humble author developed some vertical apps for casinos and gas station accounting on a 11/34 COS-300 system. 25 years later I'm still supporting some of that legacy DIBOL code, now migrated to VMS and Alphas. Old business apps never die, they just migrate to the next box... COS-500 was for larger customers, who typically ran RSTS on 10 or more terminals. BASIC was more common on these systems, which could range up to a PDP-11/70. I seem to recall there once was some sort of 5.25" floppy distribution in the early 80's. It had RT-11 v4 and was primarily for 11/23 and 11/73 systems. This was for the odd dual floppy came out with, where two drives shared one spindle and the top floppy was upside down. These were single sided (400KB?) and used FILES-11 for the file system. DMS-500 was DECs answer to the PICK operating system. PICK had made substantial inroads in the medical field, especially hospitals, so DEC came up with the same "put everything in the database" concept. Real CODASYL databases were too big for PDP-11s so DMS-500 was the low end answer if you couldn't afford a PDP-10 or PDP-20. As I understand PICK eventually migrated to the IBM RS/6000 but DMS never got much support from DEC sales. I think there was some version for VMS but it wasn't a major player on the VAX compared to DBMS-32 and later Rdb and Oracle. Jack Peacock

Amstrad PPC640 (PSU's Polarity and Amps needed)

by 3sdiarftt02＠sneakemail.com

Hi all, I've just been skimming the archives and while I've spotted a couple of Amstrad PPC640 threads, one of which confirms that you can use a normal 12V power supply, none of them indicate the amps needed nor the polarity. I found one of these units at a swapmeet a month or so ago but it was sans power supply. I'm hoping to get it up and running within a couple of weeks for a demo in an introductory computing class.

Dec VR320 monitor

VAXserver 3100

by Qstieee＠aol.com

To find DEC MMJ cables, go to http://catalog.blackbox.com/BlackBox/templates/blackbox/search.asp and look for keywords DEC MMJ. You will probably need at male-male MMJ and a female MMJ to DB9/DB25. AS with any serial connection, verify pins (on a DB-25) 2-7 and 3-7 (i.e., make sure terminal/PC is transmitting on one line, DEC VAX is transmitting on the other). I usually do this with a VOM; transmit will be a strong (5-15 VDC) signal; receive may be around 0. Usually you will get a >>> prompt from VAX firmware. It will accept a help command and you can do "show devices", then try "boot dua0:" or some other disk device that's listed (they are 99% devices beginning with "d"). Of course you may get a very first product/CPU ID, then some testing messages. You are hoping that it progresses through the self-tests and gets you to the >>> firmware prompt. Often >>> will take a "help" command too. Often you need to send "delete" and not "backspace." Try 9600/8/N/1 settings. Also probe the Compaq, Montagar, and Process sites. With the VMS hobbyist program you can get going pretty well these days.

They are ROMs, but EIS/FIS is for the 11/03 KD11 processor, not the F-11 family. CIS is a set of microcode ROMs for the F-11. There's quite a lot of information in the KDF11 CPU Module User Guide, and probably more in a technical manual. Basically, it seems that the the microcode is stored in a device with two bidirectional 16-bit busses (MIB and CDAL). MIB is a multiplexed bus. Part of the time it outputs the current microinstruction and the rest of the time it receives control signals from the CPU. The CDAL bus (which is actually a 22-bit bus, but only 16 bits are presented to the option sockets) is what eventually connects to the external BDAL bus, but it's also used internally for control signals. -- Pete Peter Turnbull Network Manager University of York

Folks, I emailed a couple of days ago about the H89 and back issues of REMark and Sextant that I have. I was surprised at the level of interest. Someone suggested I post the items on ebay and I have done that. H89 is at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=1247&item=2087562 690 REMark issues are at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=2243&item=2905394 499 Sextant issues are at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=2243&item=2905396 513 Thank you, Chris ----- Christopher D.

The relevant instructions are built-in on the 11/23 and 11/24 KDF11 processors. The options for the KDF11 are KEF11-BB CIS (dual-width), DC304 MMU chip, and KEF11-AA floating point. -- Pete Peter Turnbull Network Manager University of York

Mac Portable M5120

How should I sell it? Probably under $100 Try posting to the LEM Swap list (go to www.lowendmac.com, look under mail lists, subscribe, post). There are some collectors there. Or try eBay. Just don't hold out for a grand, it isn't likely to happen (won't say it won't, I think we all agree we have seen some pretty insane eBay deals go thru). -chris <http://www.mythtech.net>

If whatever audio setup you have gets its timing from the main system clock then you're out of luck as all the audio would sound wrong, but I image they all have their own on-board timing. I remember booting an old 486 at around 3MHz once, just to see if it would work. It did (took about ten minutes to boot!) but the beep on startup lasted for about a minute :-) cheers Jules __________________________________________________ Do You Yahoo!?

This was packaged in COS300 and COS500 os's. These were if I understood it right RT11 + Dibol and RSTS + Dibol respectively. I wonder, EIS/FIS chip as well as CIS are basicalley Roms that expand the microcode control store of the F-11 microprocessor. True? If so, whats the word-width and depth of this Rom, and what's the timing? Does anyone have doc's on this? Would be interesting to see if I could make a CIS "emulator" from standard components. I know that the CIS is a six-chip carier-assembly spanning two sockets on a 11/23+ CPU-board Regards, Frank Arnold

Somewhat OT: ISA Compaq TV Tuner Card

by SecretaryBird＠SoftHome.net

I just recently picked up an old 8 bit ISA TV Tuner card, a Compaq MG9910-20893. On the label it states "For use only with Compaq Computer Products." Anyone here ever have one of these? If so, is it true that it can only be used with an actual Compaq system, or will any DOS/Win 3.1 system with ISA slots work? I need to know before I try to test it. If it does require a Compaq system, then I will have to pull the hard drive out of my Linux Box (a Presario 9546) and slap in another drive and install DOS 6.22 and WfW 3.11. But if it will work in any system, I can just add it to the old 486/DX-33 I set up just to run classic DOS games without having to do the great hardware shuffle. Also, if it does require a Compaq system, has anyone out there used one of these cards under Linux? Thanks -- Scarletdown

VAXserver 3100

by jwb＠paravolve.net

I have come into posession of some old DEC equipment... A VAXserver 3100 Storage Expansion Unit (?) and a VaxStation 4100 (?) (?) These look pretty stripped, dunno much bout VAX hardware so I can't really say how bad. The VaxServer 3100 looks to be mostly complete and gives me some beeps if I turn it on.. I wanna try and get the 3100 to a running state (or at least determine if its worth it) ... Anyone have any pointers to information about this specific model? (it seems that the VAXServer 3100 has a number of submodels /w different connections on the rear?) Or, more specifically, how to determine what model it is *specifically* (other than the nameplate on the front).. The backside says the model # is DJ-31CP1-A, however a google search doesn't turn up much. The type of and location for serial consoles would prolly be the biggest help, so I can actually get some output from this thing. Thanks in advance, -jwb

IBM 5114

by cb＠mythtech.net

An IBM 5114 box, that is just a dual 8" floppy cabinet... yes? Are both drives the same? (mine have hand written stickers marked D-80 on one, and D-40 on the other) I just dug mine out enough to look at it, and that is all it appears to be. However, I could have sworn that at one point I had a 5 MB hard drive unit of about the same size (I even had some old 8" floppies that claim to be backup of a hard drive). Is there a hard drive built into the same box? The 5114 has been under my 5110 for many many years, burried in the back of my telco room. I assume it is the floppy drive unit we used with the 5110, but then, I had assumed it was the 5 MB hard drive that I thought we once owned. Maybe now that the 5110 and 5114 are undug, I will take them out and play with them. I unzippered the bag to the 5110 far enough to confirm that it is indeed a Basic/APL switchable unit like I thought. So now the question is... what hard drive was there for use with either the 5110 or the System/23? I don't know which system my backup floppies go to, but they are the only two systems that I ever had 8 inch floppies for, so it must be one of them. (and then the bigger question is... where did my hard drive go?!? It isn't like it can get up and run away... and I'm assuming it is large enough that it can't really be hidden in a corner anywhere... although I did overlook a System/23 datamaster for a number of years, so anything is possible) -chris <http://www.mythtech.net>

Why not get creative? I can send you a scan of the display cover. Go down to TAP Plastic and have them cut a piece of plastic for you and polish the edges. Using a color printer, there about a half dozen ways to apply the lettering to the plastic, >from using a overhead transparency to creating your own decals.

apple llc computer

by cb＠mythtech.net

>I have several apple II+ computers, several disk drives, a lot of >software and accessories. I'm always on the lookout for an inexpensive SCSI card or hard drive for the Apple II (any model II is fine, I know they were most common on the IIgs). I'm also on the lookout (again, inexpensive) for an AppleCat modem (just so I can finally have one, then call a friend that eons ago promised me he would share some software with me... but ONLY via modem, and he insisted that since he had an AppleCat, I had to have one too... just gotta get one and then bust his chops about it) -chris <http://www.mythtech.net>

An original Compaq "portable"

by JOHNSOY＠aol.com

I want to thank you for your answer concerning the Compaq Portable. It has all the manuals and it is in mint condition. It has about 75 disks that were in the box. It has the original books entitled Basic Version Reference Guide.(3) It has the Silver Logo on the case so it is one of the first made. They later upgraded them to a "plus" model which has the Gold Logo. I am really impressed with the condition. It also works. I ran across it at a consignment shop and it needed a home. I am not sure what I am going to do with it. Thanks again, YVONNE Y
