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. If anyone has one they'd like to sell, please let me know.. __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

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

Surreal. I just tried to format a 720 in my new WinXP portable and the size wasn't even a option. And when I did it through the GUI under 2000 the anti-virus scanner had a fit. Finally had to format it using the CLI *and* I had to explicitly unmount it first to get the anti-virus software to let go. Thanks Jim, Chris J.

Dec VR320 monitor

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

I remember thinking that these were the coolest portables ever. Mind you, I had been using a Kaypro 4 for a number of years beforehand, so *anything* looked sexier.

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.

Swami John, ;-) A friends family resides outside of Kashmir (hope I spelled that correctly). Would their intervention streamline this transistion ? They often ship to their son with few problems and are willing to assist, this assumes that the part is located close to their residence.

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

by peacock＠simconv.com

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.
