# Using the John Oliger Expansion System to Create Instant-Load (EPROM) Software for TS/1000 Computers, Part III

In part Il last month, we showed you how to program two 2764 eproms, one with [HOT-Z](http://localhost/product/hot-z/), the other with the Oliger machine code downloading routine.

Now, we are ready to program our final eprom with “CETCH2”. This is my program which demonstrates some of the features of the [Oliger Video Upgrade](http://localhost/product/video-upgrade-project/).
