Just to pass along some recent developments...

4M EPROM's have reached parity in terms of price/bit with 1M EPROM's.
Pat McCarthy & Mary Burnias have quotes from TI of $14-16 each.
Warrior and Danger Express both plan to use them. I expect that 4M EPROM's
will become a standard part for us in 1992. We will continue to use
1M EPROM's in the program area in 1992, but I expect that usage to 
diminish through out 1992.

4M ROM prices are even better @ $6.00 each in qty ?? I think we can order
a minimum of 1000.  I think Pat amortized mask charges into that. 
See him for the details.
