ecoinf3.c [David Haywood]

- Added some 8255s (maybe too many, not sure how many the PCBs have) and identified where it writes the 'VFD' strings.

/* Electrocoin Pyramid HW type */
// this seems to not like our Z180 timers much?
// also quite a few of the reads / writes are fall-through from Z180 internal reads/writes
// assuming this is like the other hardware EC produced the IO devices should probably
// be several 8255s on 4-byte boundaries
