They call the color "silver", but now you can print your own objects to match the early TRS-80 cases: http://www.makerbot.com/blog/2011/10/05/just-in-for-fall-abs-in-brown-tan-e… http://store.makerbot.com/metallic-silver-abs-1kg-spool-1-75mm-filament.html

Dissolving a collection: bits for sale, including books

by joachim.thiemann＠gmail.com

Hello everyone, anticipating a move across the Atlantic in the near future, I decided to start selling a large part of my collection. I'm still adding things on occasion, but I would guess that mostly the books might be of interest to folks here. I've put the list(s) up here: http://sites.google.com/site/oldcomputerbitsforsale/home I would of course prefer is someone local can grab the stuff, but I am willing to mail things.

Machine code riddle

by cclist＠sydex.com

I'm working with an old data sample (ca. 1979) to a piece of equipment that I do not have access to. I've identified some bits and pieces of code and am trying to identify the processor. Here's what I know. The processor is big-endian and appears to be byte-addressable. The opcode for CALL appears to be D3 xx xx, where xxxx is the address of the destination. 2C appears to be load immediate instruction and is also 3 bytes long. The code doesn't look tight enough to be a p-code implementation of any sort. Does this ring any bells to anyone? --Chuck

TRS-80 Model I Power Brick

by alhartman＠yahoo.com

You can indeed open up the Model I bricks and repair them. A frequent failure mode is a fuse inside the case that blows out. My friend had one blow out, and he cracked it open, drilled a hole for a fuse holder and replaced the fuse. It's a pretty simple power supply to build a replacement for. There's a schematic on the Yahoo! TRS-80 group files section for an Australian 240v version which could be adapted to make a 110v version. The service manual is out there (Tandy and SAMS) which should have schematic as well.

Not entirely true. In my case (Mac OS X.4 on a PowerPC laptop), OpenOffice actually does a better job opening new .docx files than MicroSoft's own OpenXML converter and Word X (as in, doesn't crash). That still may not help you out, Tony. I think OpenOffice has reasonably steep platform requirements too, but at least it is open source and does a reasonable job untangling Word's formats.

OS/2

by lproven＠gmail.com

Apart from Lawrence, who AIUI is a former user - as he just gave me a pile of OS/2 boxes yesterday :?) - are there any other OS/2 users on the list? Or are there any active OS/2 mailing lists still around? I am wondering if I can get a copy of the subscription-only last couple of fixpacks for Warp 4 anywhere.

IBM Model M keyboard repair tip

by ard＠p850ug1.demon.co.uk

I think some of us like the INM type M keyboard... If you are brace enough to take the heatstaked 'sandwich' apart and replace the stkes with screws (I post the method for doign that some years back), it's easy for one or two of the 'flaps' to jump out of position when you're putting the bits together again. You then have a couple of keys that don't work and you have to take the whole thing apart again. What I do now is insert a flap then slightly stretch its spring and press it over the rear of the key plunger housing, forcing the rim of the housing between the coils of the spring. It'll stay like that, and the flap will be held in place. Fit all of them, put the rubber sheet, the membrane sheets and the base plate on, and screw it all together. Then unhook the springs by running a screwdriver along, and fit the keycaps. The plastic keyframe can be cafully cut between rows of keys (it sometimes breaks along these lines anyway). You can then use parts of 2 damaged keyframes to make one good keyboard. I am not sure what the offical sixe of head for the casing screws is. It's often quoted as 7/32", which turns out to be a smidgen more than 5.5mm. I've found both my 7/32" and 5.5mm nutdriver fit fine. Somebody was looking for some tpye M casing screws. Did you find them? I spent the afternoon making a good tpye M from bits of 2 broken ones, and thus I have soem bits over :-). I never thown anything away so I've got a box of flaps, screws, etc. I could probably be persuaded to part wit hthe casing screws... -tony

Kaypro 4 CP/M disks

by elazzerini＠interfree.it

Hi, I'm not unfamiliar with the various versions of the firmware of your Kaypro 4, but the only person that comes to mind is Dave Dunfield. In time he has collected images of boot disks of many machines. I arrange from a few months of a PC configured to be able to read and write disk images 3.5 " and 5.25", but I live in Italy. Once you've got practice on how to use the software to create boot disks is more 'easy to do that to tell it. If there is no one else to may help you I can try. I'll give you references of Dave Dunfield: At the bottom of this page http://www.classiccmp.org/dunfield/kaypro/index.htm for manual. Here for images of boot disks: http://www.classiccmp.org/dunfield/img63549/system.htm Here his contacts: http://www.classiccmp.org/dunfield/contact.htm Greetings Enrico - Pisa (ITALY)

ETH Lilith's on Ebay sold...

by jdr_use＠bluewin.ch

Whoever got that set of Lilith;s that where on ebay.de, if you are on this list that is, please ensure that you write-protect the disks. Medos, the Lilith OS, expects a writable disk, but will boot and run from a write-protected one. Otherwise you run the risk that a slight error in diskdrive or controller will ruin your disk pack. Happened to me more than just once... And don't forget to replace those Keytronic foam pads : Medos expects a keystroke before booting up ! And google for "Emulith" in case you want to try out my Lilith emulator first. Jos Dreesen

[REWARD] Request for documentation

by l4b.bogdan.barbu＠gmail.com

Hi, For quite a while now, I've been trying to get my hands on an old piece of IBM documentation for my collection before it is lost forever. So long, in fact, that I'm offering a reward of 500 USD to anyone that can find it for me. I've tried using my Google ninja skills, I've tried with IBM, I've tried libraries, and I've tried contacting a couple of patent authors that have used this as reference material. Perhaps you can do a better job than me. IBM Personal System/2 Mouse Technical Reference (S68X-2229-00, 2nd ed., Jun. 1989, IBM Corporation) If you are only able to find it at a library, see if you can borrow and scan it for me; that works just as well for me. Know that I already have the first edition of this document so I am not interested in it. Good luck! Cheers, Bogdan

Release 2 represents not merely a software update, but acomplete re-authoring of GNOSIS from beginning to end. GNOSIS provides a CAI authoring language which makes itrelatively easy for any teacher with a basic understanding of ?pro-grammed? textbooks to develop computerized tutorials for his students.Although material already written in such a format can be transformedvirtually as~is by GNOSIS into a form suitable for computer delivery, theteacher would normally be writing his own ?script?. This script. because itsimulates the dialogue one might overhear if that teacher were tutoring astudent in private, can be made to ?come to life" on a computer terminalby the addition of a few simple GNOSIS command words. Thecomputer-driven tutorial is, in reality. a compiled version of the ALGOLprogram GNOSIS writes in response to the script prepared by the teacher.In fact. GNOSIS can be designed in such a way that any of the facilities ofALGOL can be exploited anywhere in the lesson. The fact that GNOSIS has been designed to function as a reachingrather than as a testing system is reflected in program logic at all levels. Inaccord with this design philosophy. GNOSIS tempers negative andpositive feedback according to physchological context, simulates a correctresponse (and the comment which would have accompanied it) when allelse fails, encourages student control through skipping and backsteppingfacilities. and generates teacher reports which are geared to lessonimprovement.

Well adapted to structured programming methodology.SIMULA will often considerably reduce programming time compared to conventional languages like FORTRAN, COBOL or PL./l. SIMULA on the DECsystem-10 contains two major additions to the SIMULAlanguage: a system for separately compiled program modules in SIMULA.FORTRAN or MACRO-10 and a powerful on-line debugging system,SIMDDT. SIMULA compiles at half the speed of the DECsysteni-l0ALGOL compiler. The CPU time when running SIMULA programs isabout the same as for ALGOL. faster for input-output and text stringhandling. slower for stack-oriented memory allocation.

Algol 68C For PDP-10
