/***************************************************************************
SAPI-1 driver by Miodrag Milanovic
09/09/2008 Preliminary driver.
07/12/2010 Added some code to allow sapizps3 to read its rom.
With no available docs, the i/o ports are a guess. The ram
allocation is based on the actions of the various bios roms.
Port 25 is used as a jump vector. in a,(25); ld l,a; jp(hl).
According to wikipedia, e800+ is the videoram area, and the
number of columns is 64.
19/04/2012 Connected sapizps3 to a terminal. It is trying to
load a 128-byte boot sector from a floppy disk.
Modernised driver.
Connected sapizps2 to ascii keyboard. System is now usable.
According to wikipedia, sapi1 & 2 have cassette facility,
while sapi3 uses 8 inch floppy disk.
