Some more notes about the respective computers...

MM/1:
- When additional RAM is used (via second board), the original 1Meg becomes dedicated video RAM.  Then, with the two chips no longer competing for memory, average throughput can increase as much as 50%
- The palette controller is now standard so the 16/256 colors can be chosen from 16 million (2^24).

TC070:
- No mention has ever been made regarding whether of not this computer makes use of a palette controller (as the MM/1) or if it just uses a fixed 16/256 colors.

If you have any questions, send news, not E-Mail!
