IMPORTANT

The motherboard described in this document is the

first motherboard, the 16KB-64KB one.

Examples:

* Pages 200-3 and 200-4: Do not apply to the later

64KB-256KB motherboard (different bank size).

* Page 4-7: Part number shown for the system board

(motherboard) is for the 16KB-64KB one.

If the BIOS on the 16KB-64KB motherboard has

been upgraded to the third revision one, then the

switch settings shown for SW2 (“switch 2”, on pages

5-6 and 5-8) on the motherboard no longer apply.

The BIOS revision can be determined by examination of
the seven digit number on motherboard chip U33.

First revision: 5700051
Second revision: 5700671
Third revision: 1501476
