Hi everyone.

A friend recently purchased a used PK-88 and I've been trying to find at
least a current command reference for him. If anyone might have scanned
this portion of the manual and would be willing to share, that'd be great.
Or, if there is a URL I could find in Google, I'd appreciate that as well.

Depends a lot on the version of firmware in the box otherwise its
exactly like any other licensed TAPR TNC-2 clone.

The main software difference in the clones was some had "personal
mailbox" extensions. Each brand with a personal mailbox did it
differently.

TAPR will sell a version 1.1.9 EPROM and manual to you for $15 + $6
shipping. http://www.tapr.org/
