Sydex

Here is an interesting correspondence from 2005 between Herb Johnson and Charles Guzis (Chuck(G) at VCF) regarding the software products of Sydex. Sydex has distributed the products 22DISK, Teledisk, AnaDisk and 22NICE. Since 1989 it is no longer possible to purchase a registered version of 22DISK with the complete CP/M definition list. Unfortunately, the shareware versions only contain a shortened list.

But, ... once in, always in! The list can still be found on the internet. For example, in the Don Maslin archive. The original list cpmdisks.def has a size of 83, 85 or 87 KB! The shareware list is only 35 KB in size.

I can recommend the „software archaeologists“ among you to take a close look at this archive. You will find some very special DOS software treasures. Believe me!
