As you may know, Radio Shack sold the Sharp PC1211 under the name 'Pocket
Computer 1' (or PC1). They also sold pre-recorded tapes of programs for
it (AFAIK, these were not Sharp products).
Anyway, I've got the rpgorams from the 4 'Engineering Math' tapes and the
'Electrical Engineering 1' tape as plain ASCII files (BASIC progam
source). Does anyone know of a website which archives such things, if so,
I would be happy to provide them.
Anyone interested?

I don't recall the Sharp model # (there were many, as seen here:
http://www.promsoft.com/calcs) but I think the Sharp version was my
first "computer." It's long gone but I have the Radio Shack version
now. I have never loaded software for it off of cassette (or any
other medium.)
These folks are preserving software for a related model:
http://www.pc1500.com. Maybe they would be interested in expanding
backwards also.

The latermachiens, like the PC1350 (whcih is what I am using at the
moment) had a seiral port. Admittedly at 5V CMOS levels. But there was an
ooffical level translator box to RS232 levels. Very useful
As for docuemtnation, not surprisingly the Radio Shack ones had service
manuals, and some are archived on various web sites (I've found the PC1,
PC2, PC4 (Casio PB700) and PC6 (a later Casio). Sharp sold techncial
manauls at least for the PC1500 and PC1350 (I have both) which contaiend
schematics, machien code instructuion set and useful ROM calls.

THe PC1500 is actually a rather different machine. Radio Shack solde a
modified veraion (different keybaord layout, so overlays for one do not
fit the other) under the anme PC2. The PC1500 was in many ways the most
advnaced of the Sharp pcocekt computers, it had a proper expansion bus,
the processor could access 128K bytes of memory (of which 64K was data
only, the other 64K could be used for programs and data), and so on. The
BASIC was also somewhat differnet. The PC1500 (AFAIK) had no tape
compatibility with any other Sharp machine.
I cna try contacting that site, but it doesn't seem to really be the
right place.

Perhaps bitsavers.org is the right place?

I cna try... But having sent them various HP ROM dumps, etc, and been
ignored, I don't hold out much hope.

BTW, can NOS (or even used) LCD displays for the PC1211 be found? I have
one that I love, with the printer, etc. But the LCD is dead :(

I suspect it will be very hard to find one now... When the machine was
officially supportyed, Sharp (at least in the UK) were very good about
supplying spares. I ordered (and got) many psrts for my PC1500, which I
had damaged from eperiemnting with the hardware/ I remember goign to a
main dealer in London to get a replacement I/O chip, for exmaple. And yes
I did have to replace the dispaly in my PC1500 after I dropped it...
I suspect PC1211 parts were similar. And you could probably have got it
from Radio Shack National Parts. There was a Radio
Shack service manaul
for the PC1211 and it lists all the parts.

is the dispaly toally black or totally yellow? Or is tit broken?
I am told that theses machines were designed to run off 5.4V (4
mercurycells) and if fitted iwth silver oxide cells (SR44s) _some_
machines behave oddly. This is something I may be investigating...
