VIDEO HARDWARE NOTES:

- The Vertigo vector CPU consists of four AMD 2901 bit slice processors, logic to control microcode program flow and a digital vector generator. The microcode for the bit slice CPUs is stored in 13 bipolar proms for a total of 512 52bit wide micro instructions. The microcode not only crontrols the 2901s but also loading and storing of operands and results, program flow control and vector generation (see schematic in vidhrdwvertigo.c).
