When these drives came out, they were touted as being "as good as a regular floppy drive". Being 18, and of limited funds... I remember drooling over the flyers thinking of getting two of these drives and a bunch of tapes. My friends in the local TRS-80 Users Group kept talking me out of that (Kings Byte in Brooklyn). I guess, in retrospect... I'm glad they did. I remember that before I went to disk drives on my E/I, I used to load Level III BASIC (From Microsoft), which had corrected Cassette loading routines) when I would type in programs from magazines. I'm somewhat bummed out that my old Model I is kaput. I've got a bid on another non-working unit locally in South NJ, and if I can win that... I'm hoping to combine the two units into one working one. My old Model I is like a spaghetti factory inside, having the following mods: - Electric Pencil Lowercase Mod - Dennis Kitsz High Speed Mod (auto switching when disk drives or cassette are accessed). - Inverse Video (my friend added this, I hate it!) - Internal Speaker attached to cassette port (for game sounds) - Internal Alpha joystick adapter (just some diodes and a connector) - Reset Button - External Keyboard connector - Composite Video Out - Upgraded keyboard with keypad (it didn't have that originally) - XRX Mod (for more reliable tape loading - Gold Plugs But, the unit is a mess inside. I'd like to strip out a lot of the junk and see if I can get it working again. I've asked my friend who did the mods originally if he'd do that for me. Hopefully, the non-working unit I have my eye on is just a case of loose video RAM chips as the owner said it worked before he sold it to another buyer, and after it arrived it booted up with garbage on the screen. So, I'm hoping that opening the case and reseating some chips will fix it. I did a search and the 21L02 chips (1k x 8) for the video ram upgrade for Lowercase are still available. So, I can add the lowercase mod to it. And I can swap character generator chips with my old unit if need be. I'm hoping one of my two E/I's is still working so I can use it with this keyboard unit. Nostalgia... As for the A&J units, they worked pretty well when I used them at Zebra Systems. I used to load the Terminal program for the 2068 Modem onto one, so I could load it faster... I had a few carts tangle (like an 8 track player), but not many. It's funny, but in the Dennis Kitsz book he had a project to modify an 8 track recorder/player to serve as a mass storage device. The forerunner of Stringy Floppies and later Tape Drives, I guess.... I leafed through that book yesterday. What fun stuff there is in there.... I still have the whole series. Especially Disk and Other Mysteries.. Which was like my Bible back then. I can't remember how many hosed disks I recovered using that... Regards, Al Hartman

Monrobot XI Instruction Card

by dbetz＠xlisper.mv.com

In case anyone is interested, I've posted a scan of the Monrobot XI Quikomp reference card. This is the language I used to program the Monrobot XI when I was in junior high school back in the 60's. I'm not sure if this is the actual machine language of the machine but it is the only documentation that I have left. It is on my rather lame web page is at: http://www.mv.com/ipusers/xlisper/index.html

That bit of info, coupled with Google, turned up the needed info. What you need is the following Zip file mkimage_vax.zip Unfortuantly it's been removed from the website. I'll try and find it tonite, hopefully I've still got a copy.

Litton Industries Monrobot XI computers available

by dbetz＠xlisper.mv.com

I recently received email from FThomas470(a)aol.com informing me about the availability of some Monrobot XI computers. I would love to acquire one of these as the Monrobot XI was the first computer I ever programmed (in junior high school). Unfortunately, I am not sure I am going to be able to afford to ship one from Virginia to NH. In any case, I certainly can't take all 5-6 of them. If you are interested, please contact the email address above. I don't have any more information than what I'm posting here. If anyone decides to rent a truck to move them from Virginia toward New England I'd be interested contributing to the cost of the rental in exchange for hauling one for myself. Here is the text of the messages I've received about these machines: Litton Industries's Monrobot XI We are in Charlottesville, Virginia and we have 5 or 6 of them in storage. Until 7 or 8 years ago two of them were still being used and worked just fine. In their time, they were really great machines and I enjoyed programming and working with them. We also have 2 Friden Computypers which are earlier than the Monrobots. They had no electronics at all, but used rwo Friden late model mechanical calculators with solenoids on all the keys and electrical contacts on all the dials. They used a pile of stepping switches and a big plug-board for programming. It was a far-out design but worked very well. We will be moving shortly and are pressed for space. Please let me have your thoughts and/or suggestions. If you are interested, any reasonable offer would be considered. The Monrobot consists of the main computer unit which contains the electronics and magnetic drum, a little control unit with switches and control buttons and a place for the I/O typewriter. It's about the size of an office desk and weighs about 400 lbs. A side section connects to it and has a paper tape punch and a reader.

RX01 Cosmetic Aid Needed

It's just a little thing, but it's going to bother me when I mount my RX01 in my nice white rack... Does anyone have a spare white front panel for an RX01 floppy unit? Mine came without one, I believe because the previous owner (the US Air Force, I believe) removed it so that the door on the front of the H960 rack it was mounted in would be able to close. -- Owen Robertson

TRS-80 Model 4 help requested

by alhartman＠yahoo.com

> From: ard(a)p850ug1.demon.co.uk (Tony Duell) Thanks for all of your corrections, it's been some time since I worked daily with a TRS-80 Model I/III/IV. I sold my 4p several years ago (where most of my Model IV experience comes from). I agree with you vis-a-vis the floppies. Maybe the drive is just off speed, and needs a head cleaning. It could be worse off. Drive speed can be roughly adjusted using the decal on the motor and adjusting the pot on the speed board with a non-ferrous screwdriver (like a TV Adjustment tool). I think when I go to Trenton next May, I'll keep my eye out for a Model III or IV. Thanks again! Al

It's not that hard to make something that will work. The distribution panels that split up the signals from the RXDX1/2/3 boards to connect to RDxx or RX50 are mostly just rerouting signals (some include some buffering). I've made up two of my own; one simple one, on Veroboard (stripboard), and one as a PCB. If you look in http://www.dunnington.u-net.com/public/RQDX/ you'll find the PCB layout and component overlay, along with the RQDX pinouts, for the larger of the two I made. It includes provision for switches or jumpers to do the job of the front panel switches. The circuits for the switches, inbcidentally, are very simple -- a latching switch, LED, one transistor (to invert the signal, as I recall) and a few resistors. It needn't even be as complex as that. I once traced out and re-drew the schematic of the M9058 board, but I can't find the PostScript file now :-( If I ever do, I'll post it on the website as well. -- Pete Peter Turnbull Network Manager University of York

Large, multi-button mouse recommendations?

by Robert_Feldman＠jdedwards.com

Forget mice -- get a good, large track ball. I use an 2.25" Atari arcade trackball that I put in a custom cardboard and foamcore case, with two arcade button switches. I got it from Happ Controls (http://www.happcontrols.com/). Current price with USB or PS2 interface is $145. When I got mine (almost 15 years ago, so it is on-topic), it did not come with a PC interface, so I cannibalized a cheap serial mouse and made an interface. I think I still have plans I made up for that. I have had to clean and lube it only once in >10 years. I have it hooked to an IBM T20 laptop -- in its box, it's nearly as big as the laptop! -----Original Message----- From: Bill Richman [mailto:bill@timeguy.com] Sent: Friday, February 28, 2003 8:28 AM To: cctalk(a)classiccmp.org Subject: OT: Large, multi-button mouse recommendations? I've been doing a lot of finicky CAD work recently, and my hand is really starting to hurt from gripping the mouse tightly for fine control. I'm looking for a larger mouse (according to one site that sells various sizes of mouse, I'm between a "large" and an "x-large" hand size) that I can lay my hand more or less flat on top of (maybe with a couple of finger loops, so you don't have to grasp it constantly) and ideally with a small multi-button keypad of some kind on top. Is there such an animal out there (aside from the Space Mouse guys' $500 products) that might have these features? Suggestions welcome.
