Thank you for your valuable response. I AM going to investigate the memory
situation more deeply. I had just installed 2 newer 4MB Kingston KTC-4200
modules on the OEM expansion board and I can move things around while still
retaining 9MB of RAM for the OS.
I put a few additional comments in your reply below...thanks again!

Great ideas...I'm going to give them a whirl!

New to unix, I'm not sure how my limited memory will eventually affect the
performance. But I have partitioned the drive. After much experimentation
and learning disklabel/fdisk/bios etc...etc...I've come up with the
512MB - MSDOS
512MB - unused
512MB - /
512MB - /swap
1GB - /usr
1GB - /tmp
2GB - /var
2.8GB - /home
I couldn't pass up this 9GB hard drive. $15 USED from Computer Geeks
(compgeeks.com). Full height, to replace the OEM 130MB full height MFM HD
in the Compaq (LED, black face plate and all!). Add that to the $15 Adaptec
SCSI/Floppy controller, when everything worked on the first try...I was in
Geek Heaven for few days...let me tell you!

Price is a only minor object, $20 here/$50 there. The real the goal:
education...a cool Unix machine from the 80's...and a
programmable/adaptable/secure firewall/NAT that can run nmap :-).
My next step will be upgrading the motherboard & powersupply. I have my eye
on this big 90Mhz Pentium tower (at work) that is going to be phased out
(read: free). It looks like it might fit inside the Compaq's box fairly
easily while retaining all the cosmetic parts (floppies/hard
I really love how this Compaq machine looks, the only "PC" computer from
the past that would look cooler running Unix would be an Original IBM PC/XT
(5150) or one of those Kaypro luggables with the mini screens. (Future

Thanks again for your response!
