Looking for : Sharp PC-1405

by mhstein＠canada.com

--------------Original Message------------------ Date: Fri, 17 Jan 2003 16:27:36 -0500 (EST) From: liste(a)artware.qc.ca Subject: Looking for : Sharp PC-1405 Or equiv (Tandy had them as PC-2 or something, iirc). The goal of my classic collection is to get one of every computer I've programmed over the years. One of the first computers I programmed was a PC-1405 (actually, I can't remember the exact model). I found one of these in a pawn shop. By brother "stole" it. I found another. This was my one classic computer that was helluva useful. So useful I took it with my places. And, well, I've just lost it. I've checked eBay and there are a few Sharp Pocket Computers, but W@W L@@K @ T3H PR1C3Z! Buy it now for "only" 300 USD! http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&item=3000156764&category=15030 So, does anyone here have one they don't need and/or would be willing to let go for a reasonable price? -Philip -------------------------------------- I've got a PC-1421 Financial Computer if you (or anybody) are interested: 76 character keyboard 16 character display 40K ROM Basic 4.2 Kb RAM Interface for optional CE-126 Printer/Cassette (don't have) 6 modes: Normal calculator Financial calculator Statistical calculator Basic program mode Basic run mode Almost new, in box with cover & 280P manual. Make me an offer (less than US$ 300, or even CDN$ 300 :). mike

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

Repair Culture

by pontus＠Update.UU.SE

Hi Just read this article from "bunnie". It gives a, to me, appealing vision of a return to what I think is quality: http://www.bunniestudios.com/blog/?p=1863 I hope at least some of what he says is true, although it might preclude the singularity, which sounds fun :) regards, Pontus

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. I believe there were entirely discontinued around 2007, so I really doubt that IBM cares any more! -- Liam Proven ?

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)
