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!
So, does anyone here have one they don't need and/or would be willing to
let go for a reasonable price?
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)
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 :).
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
Does this ring any bells to anyone?
Just read this article from "bunnie". It gives a, to me, appealing
vision of a return to what I think is quality:
I hope at least some of what he says is true, although it might preclude
the singularity, which sounds fun :)
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!

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
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
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
