If you have at least 8meg of ram in that 486 try Linux, Freebsd, OpenBSD
or NetBSD. These are all free (maybe a few dollars for the CDrom) and
represent high performance unix operating systems of various flavors
that are mostly similar if not the same. I'm not a unix fan but compared
to MSwinders and the dos similars (other than OS/2 warp or concurrent cpm)
it's a real screamer.
Another one if your interested in OS internals is Minix, the disk set to
install on a 486 is only a dozen floppies and it will fit with sources
on a 40mb drive. It's unix but simpler, of the V6 flavor. it's
simplicity makes it quite fast!

I finally put up some new shelves and was able to go through a few boxes
of books today. What I ended up with was a few spare things, which are
available to anyone who wants to pay shipping. Anything unwanted will go
to the recycling bin for Tuesday morning's pickup...
SunOS 4.1 System Manual, volumes I and II (missing III, it may be here)
SunOS 4.0 Network Administrator's Guide
SunView Programmers Guide
(above are in large 3-ring binders)
Sperry PC-IT Manual set (System Guide, DOS, BASIC mini-binders in boxes)
Please contact me privately...

"UNIX is an exponential algorithm with a seductively small constant."
good size hamfest in greensboro, nc and here is what i picked up.
epson hx20 complete with plastic carrying case. where can i get the tiny
cassette tapes for it and it also has a expansion unit added on the left. what
does that do? no ac adaptor to test yet. the guy also had a commodore sx64,
but too expensive. also picked up a ps2 model 60 that worked fine once i ran
reconfig on it. an interesting find is a complete ti99/4a system still sealed
in its box along with the expansion unit and optional floppy drive, all for
$15. the 3 boxes were never opened until i did it. it's the beige model
rebadged by CDC for schools here in raleigh. i also got ~50 disk based school
software titles for it as well. all of it's worthless of course, but
interesting to find something well over 10 years old and never saw the light
of day until now.

I believe the two 9 pin connectors went to a printer and to a modem if you
needed one. Prob. both are serial ports. I may have printer cables in my whse.

I have one operating! What I don't have is docs other than my memory.
I post quarterly or so a "anyone seen dos for this one" request.
What it has... 2k of ram that you can run programs from a 1k monitor
that can save to cassette and TTY/papertape. The interfaces include OPTO
isolated, relays, TTY 20mA currentloop interface and also a audio casette
interface.
It was a foray into 8035/8048 SBC market.

Hi gang
I just pick up a new, which is to say, old system. Of course, it has no
suppoting information. I bought it as an 'IMSAI 8048 controll computer'.
Its in a nodescript molded black hardshell case, has a hex machine coding
panel/keyboard and nine digit led display. Opening it up reveals a single
board system +- power supply. Primary chips on the board are i D8243, i
D8279-5 (sublabled 4404A hmmm...), and a NEC D8035LC. At the bottom of the
board: c 1977 IMSAI MFG CORP., SAN LEARNDRO, CA... and this at opposite
corner: 8048cc REV. 1 AR 1.
Did that send anyone into a flashback???
Thanks

RL01's are 5 Megabytes - 10240 512-byte blocks, to be exact.
You can still buy them new, from DECDirect (1-800-Digital), for
~US$200 a pop.

Hey all -- sorry if this is uninteresting -- I have no idea about the age/value/rarity of these machines, but the CS dept here is selling them, and if anyone's interested, email me privately. This is forwarded from the lab admin. -- MB

* DecStation 500 - the old risc (not alpha) Dec, with
keyboard, mouse, and video cables, but without monitor
and scsi disk. Apparently these run FreeBSD, though
I have never tried it. They don't run Linux.
$100 each.
* Sun IPC - one of the early sparc architecture machines,
it is old enough that most people have never heard of it.
I believe that it won't run the newest Sun OS. With
a huge 19" or so color monitor, 16 meg memory, and hard drive.
One only. $250
* Mac IIci - I have about ten of these puppies, no
monitors, but probably a mouse and keyboard if you act fast.
$35
* Sun computation center - a Sun-60 desktop server with scsi disk,
a sun-120 vme-bus machine with non scsi tape controller,
and a 9 track reel-to-reel tape drive. You must remove
the (very heavy) tape drive from the rack that it is in.
This was much faster than the Vax 11-780 that used to
be the heavy Unix machine on campus, back in '89.
$250 takes it all. Bring a truck.
Small print:
All sales are final. This equipment is sold "as is" with
absolutely no warranty. I am not able to answer any questions
about software installation or setup. You can try the
equipment if you want to do all the lugging. The equipment must
be removed from Sudikoff Lab within a month - if I find it
around after that I will throw it away! There may be
viable operating systems on the disks of any machines with
disks, but I am not selling any rights to use the software or
offering upgrades or replacements. (I believe that the Sun
right to use goes with the equipment.)
Prices are negotiable. In cases where a disk is included I
will sell the item for substantially less without the disk
or disk enclosure.
If you have to ask how, it is probably not for you....
I built one, once upon a time, out of a Univac keypunch keyboard and some
TTL logic.
Worked great. Used it on my Altair for years Really nice LOUD CLICKS.
Loved it.
I suspect this would be tough to do with a modern PC keyboard, but if you
look at
really old stuff (like at a state/university surplus sale or some such) you
might find
something.
