I have extra copies of the following available.
These are all probably for a Pro 350, if there is
any machine dependency, and are all circa version
2.0 of P/OS. The software for the last version
(3.2) is available at ftp.update.uu.se.
Hard Disk System
For Beginners
User's Guide
User's Guide Supplement
Command Language User's Guide
PRO/Sight User's Guide
A few miscellaneous "Installation Manuals" for options.
If any is interested, let me know. I'll send these to
anyone who'll pay postage plus a small packaging fee,
total to be determined, but probably not more than $10.
