That package is no longer available. You may be able to find someone selling a package on eBay.
We were selling too many different package support levels and the upgrade paths were becoming quite complex. People purchased Rel 2 205 only package, then Rel 3 05 only package, then upgrading to Rel 4, and expecting 06 support, just to save a few bucks.
We dropped the price of the full package by $100, and we offered the DirectSOFT100 package for free (better than the Brick price), but limited for truly "brick" applications (around 12-16 I/O). Also, the upgrade package upgrades to the FULL package (e.g. if you have a Rel 3 05 only package, and purchase the Rel 5 upgrade, you now have support for ALL DirectLogic PLCs!).
The "brick" PLCs are getting larger and larger (e.g. 06 with 4 expansion slots), supporting as much functionality of the "higher end" PLCs (e.g. PID, floating point math, etc.), making the differential between a "brick" PLC and "high" end PLCs even more blurred.
We determined that the only "sure way" to distinguish between "low end" and "higher end" applications is program size. So if you have a "simple" 260 CPU or 450 PLC with a simple program (regardless of I/O count), the DirectSOFT100 package can work, but the BRICK package would not have worked (it only supported 05 and/or 06).
However, we did not want the guy who truly wanted a $99 PLC with a simple application to have to purchase a $395 package, making the DirectSOFT100 package FREE.
We also realize that there would be people "on the bubble" like yourself, but regardless of where that line is drawn, there will always be people on that bubble. We apologize for the inconvenience.
