The SX is, beside some minor changes and a complete different
layout just a way ordinay 64 - so no special chips - grap
another 64 and exchange the chips - basicly everything
may be damaged .... except the RAM - RAM errors are quite rare.
All relevant chips are socketed.

Hi all!
Just curious, but are are the prices of these Sun NVRAM timer chips
these days? I am looking for a replacement
for the old SG Thompson M48T02 chip. Here in France they are on the
order of $45-50!! What has happened
to last year's $20-28 ? Are the Dallas chips identical to the ST ones,
as concerns a Sun?

I found---completely at random, in a bin of completely unrelated cruft---
the media interface half of an Asante MacCON/30ie (the ethernet card for
the Mac IIsi or SE/30 at a recycler's yesterday.
I picked it up for $10 because I thought I remembered somebody on the list
was looking for specifically this half, but I can't remember who.
It has both UTP and AUI interfaces, and all you need is the PDS half and
the cable to connect the two. It's a standard IDC ribbon cable. I haven't
counted the pins yet, but it looks as if it could be the same width as a
ST506 data cable.
If you're out there and you still want it (I should've haggled), contact
me off list.
ok

Although it's not directly classic computer related, I got a kick out of this
email I received today. Some of you may enjoy it... Remind me to tell you
about the fun I had a few years back with surface mount MIL-SPEC 0 Ohm
resistors. (Yes that is a zero).

I assume that as DOS is over 10 yrs old this is on topic ;-)

1)
I am thy DOS, thou shall have no OS before me, unless Bill Gates gets a cut
of the profits therefrom.
2)
Thy DOS is a character based, single user, single tasking, standalone
operating system. Thou shall not attempt to make DOS network, multitask, or
display a graphical user interface, for that would be a gross hack .
3)
Thy hard disk shall never have more than 1024 sectors. You don't need that
much space anyway.
4)
Thy application program and data shall all fit in 640K of RAM. After all,
it's ten times what you had on a CP/M machine. Keep holy this 640K of RAM,
and clutter it not with device drivers, memory managers, or other things
that might make thy computer useful.
5)
Thou shall use the one true slash character to separate thy directory path.
Thou shall learn and love this character, even though it appears on no
typewriter keyboard, and is unfamiliar. Standardization on where that
character is located on a computer keyboard is right out .
6)
Thou shall edit and shuffle the sacred lines of CONFIG.SYS and AUTOEXEC.BAT
until DOS functions adequately for the likes of you. Giving up in disgust is
not allowed.
7)
Know in thy heart that DOS shall always maintain backward compatibility to
the holy 2.0 version, blindly ignoring opportunities to become compatible
with things created in the latter half of this century. But you can still
run WordStar 1.0
8)
Improve thy memory, for thou shall be required to remember that JD031792.LTR
is the letter that you wrote to Jane Doe three years ago regarding the tax
deductible contribution that you made to her organization. The IRS Auditor
shall be impressed by thy memory as he stands over you demanding proof .
9)
Pick carefully the names of thy directories, for renaming them shall be
mighty difficult. While you're at it, don't try to relocate branches of the
directory tree, either.
10)
Learn well the Vulcan Nerve Pinch (ctrl-alt-del) for it shall be thy saviour
on many an occasion. Believe in thy heart that everyone reboots their OS to
solve problems that shouldn't occur in the first place.
Here's an interesting e-mail I got this morning. Obviously these guys
have been monitoring the list.
I wonder if they take Altairs?

I just found in the original box, minus software and documentation a
"Calcomp Drawing Card". It is a full length ISA card with an attached
daughter card that can display 16 or 256 colors of a palette of 4 million
colors at 1024 X 768. The ROM chips on the board are all labeled 1987. It
says it works with IBM PC AT.
Anybody know anything more? I tried a google and altavista search but only
hit was for a grayscale version.
