PCjs Personal Document Collection

Much like the PCjs Personal Disk Collection, this is an assortment of old documents archived by @jeffpar that may or may not be of historical interest.

We’re kicking off this new section of the site with a couple of documents created by @jeffpar in 1984, detailing his early adventures in PC debugging: disassembling and disabling dBASE III Copy-Protection.

dBASE III Copy-Protection

• dBASE III Debugging Notes
• dBASE III Patching Procedure

NOTE: Copies of the dBASE III disks can be found in our IBM PC Disk Library.
