/* AMSSIO-II (v4) */
=== AMSSIO-II (v4) ===
AMSSIO-II is a newer version, using a 16C850 instead of the MC6850. Aside from the schematic (see below), there is no documentation or source code for AMSSIO-II. I/O base address can be FBE0h or FBF0h (jumper-selectable).Unlike the previous versions, this version also connects to the Z80's interrupt input.
