Full strength Lime-Away will usually dissolve it. If it's on painted
metal surface or plastic that acid won't hurt, I have full strength nitric
acid to dissolve it.

Quoting from BYTE September 1990, from an article "The creation of the IBM
PC" by David J. Bradley (who worked on the development of both the
DataMaster/23 and the IBM PC):
==============================================================
The DataMaster was an Intel 8085-based system intended to run business
applications written in BASIC.
The one-piece DataMaster was a business-oriented single-user system. It
served as a model for many of the features of the original IBM PC. The IBM
PC keyboard came from the DataMaster.

Folks,
I've borrowed a universal device reader/programmer (MQP Pinmaster 48) and
I'm trying to dump the ROMs from my dead TRS80. It claims to be able to read
anything because of its completely configurable design (with an appropriate
adapter for non-DIP style packaging) and I've already dumped some EEPROMS.
However, it doesn't like either of the TRS80 chips (NEC 4K marked as 2332
and 2364) nor the ROMs on my Tangerine Microtan 65 TUGBOARD (4K roms again I
think).
This thing knows about over 6500 different *ROMs so maybe there's an
equivalent name I can feed it to see if I can read these ROMs? Is there
anyone with a TRS80 to hand who can tell me what ROMs theirs contains?
TIA!

Hi
I'm told that some vinegar will remove rust stains. Try
putting a piece of paper towel on a small patch and wet it
with white distilled vinegar. Let it sit for a few hours
and see how it does.
Even if it doesn't work, what do you have to lose.

Technically I guess it wasn't a find, as this time this one found me...
A friend found a SuperPET in someone's trash pile this afternoon and
dropped it by. It came with a 2040 dual drive floppy disk and the IEEE
interface cable. It is pretty rough looking and according to the friend,
was in the former owners garage for quite some time. It looks like it sat
on the cement floor for awhile too, as it has lots of small rust spots.
On that note, whats the best way to clean up rust spots on these types of
systems? Should they be buffed out or is repainting a better idea?

(mumble) (blush) er... ahh... it must be here somewhere.
Earliest thing I have is from July 1997, which probably doesn't put
me in the top thirty. But I've enjoyed the group enormously anyway.
Re: charter mods:
I love being able to ask about my NeXT on here, so 10 years
is a nice number for me. 15 would be OK, I guess.
I do think there is value to questions on how to run new
software on old (>10 year) hardware.

I suspect there are very few "how do I fix my PC" annoying
questioners who are using *either* hardware *or* software more than
10 years old.
My vote is to keep the 10-year limit [1], and clarify it to
make clear that if either the software running or the hardware it's
running on makes the 10-year limit, it qualifies.

quality time with....it's pretty fresh-on.

I've got a VLB-based 486 in the bedroom.
I believe there are only 2 public domain OSes for the Pro series.
One is the infamous PO/S and the other is Venix. Both are
available from <ftp://ftp.update.uu.se>ftp.update.uu.se. You need
<http://64.253.97.239/pdp11/Proaccms.zip>Proaccms.zip if
you run Venix and have acess to a MS-DOS machine.
<http://64.253.97.239/pdp11/Proaccms.zip>Proaccms.zip is available at
www.saracom.com :)
RT-11 does run nicely but it is still copyrighted. I don't
know about whether the other OSes will run.

Now that one deserves execution! I would not settle for anything less
