I seem to have lost my copy of the instructions posted to the net for upgrading the memory on the motherboard of a 7300 from 512K to 2M. I'm hoping someone could repost them or mail me a copy.

I bought a UNIX PC in the fire sale (gosh, is that a few *years* ago
now?) but, unlike all you skilled folks, never really played with it
much - the big machines at work (Gould and Motorola) were rather more
fun to play with. Besides, once you've gotten used to a big screen,
you don't ever want to go back.
Oh, I know my machine works - I use it off-and-on, occasionally,
for quick midnight hacks, etc. - but I've lost touch with the latest
and greatest in 3B1 land.
However, circumstances (a desire to return to the life of a grad
student) may soon remove my access to the machines at work --- and
computer access at my university is somewhat confining.
So, I now return to the unix.pc newsgroups with a whole slew of
questions:
(1) Are the unix.pc* newsgroups archived anywhere?
(2) What is the latest and greatest on unix.pc software extensions?:
a) Upgrading my OS:
I have UNIX 3.51 (I think).
Undoubtedly there have been bug fixes since.
How do I get them?
b) Customer Support
AT&T seems to have forgotten I exist - can I get in touch
with them to find out the latest "official" 3B1 software news?
c) PD Software
i) GNU EMACS
I got (and still use) the original GNU EMACS distribution
from Brad ?? for my 3B1. I'm sure it's been updated.
Does standard GNU work OK? Anyone have a list of files to
eliminate?
ii) GNU CC
Ditto - I'm sure this runs on the UNIX PC without too many
workarounds now. Is the standard distribution the place to go?
iii) wordprocessing, TeX
Is there a CTeX around for the UNIX PC?
Is there a PD approximation to nroff anywhere to be found?
(my "printer" is an RX-80 - not very sophisticated)
iv) document previewer
v) X
Has anyone bothered to get X working on a 3B1?
How about connected to an X terminal (serial link)?
vi) comm
Anyone have alternatives to the default terminal and file transfer
program? The terminal is pretty slow... How about SLIP?
vii) uucp
Is HDB still AT&T private? Any alternatives?
d) Alternative OS
Has anyone ported XINU? MINIX? MACH?
Or any other almost-freely-accessible OS to the UNIX PC?
(3) What is the latest and greatest on unix.pc hardware extensions?:
a) extra disks
I heard that there is a "kit" for using more than 8 heads
and all the tracks on a disk - plus something to let you have
more than one disk. Can someone point me to it?
Given that, can someone point me to a good source for
the actual disk? I have 67M now, and basically want to buy as
more space as I can afford.
b) disk controllers
I apparently just missed the WD2010 group buy.
Can anyone tell me about it? Is anyone else interested?
Any pointers to purchases in quantity 1?
Exactly what does it get you (faster seeks?)
c) SCSI
Is there still a SCSI board for sale? Is it any cheaper than
it used to be (2K$)? Did any hobbyist homebrew his own?
d) Backup
Tapes? EXAbytes? (off SCSI?)
e) Processor upgrade
Has anyone plugged in (daughterboard) a newer, faster, processor?
Joe Hollinger was going to try a 68020 a while back - are you still
around, Joe? Anyone done a 68030?
The idea of using the 68030's MMU to get >4M processes is
appealing - but that would have to run all around UNIX.
f) Memory upgrades
Are there any upgrades, eg. to get more memory on the motherboard?
Offboard? Beyond 4M?
g) Virtual Memory Upgrades
As I remember it, the 3B1 is limited to 22 bits by its MMU.
Has anyone gotten around this?
(If I want to do some of my research at home, I will
*need* more than 4M of virtual address space per process).
h) Laserprinter
...
i) Display
Anyone connected a larger display, with more bits?
I'd appreciate help with these, or any other, steps towards making my
3B1 my new home machine.
My priorities are getting PD software, and getting more disk space to
hold it on. My constraint is lack of cash.

I have a fully functional AT&T 7300 UnixPC for sale. It has 512K of RAM, a 20M disk, the 3.0 foundation set, and owner's manuals. The 3.51 foundation set and Fixdisk 2 are installed on the hard disk. The logic board has the P5.1 mod, but not the PAL for it. Asking $500 OBO. This unit was previously used successfully with the P5.1 PAL and a WD2010 disk controller, which allow the use of ST-506/412 type drives with more that 8 heads and 1024 cylinders (such as the Maxtor XT-2190). I could include these (but not the Maxtor (-: ) at an additional cost of $5 and $15, respectively. For additional funds (make offer) I could provide a 2M RAM logic board instead, or provide the chips, sockets, and instructions to allow an adventurous person to upgrade the 512K logic board to 2M. I was going to upgrade it myself, but never found the time. I also could sell a Hitachi 40M drive from a 3B1, and a 3B1 case top and monitor, but I don't have the 3B1 power supply. -- Eric L.
