This IDE I/O card is typical of those found in some 'Clone' machines.
They are cheap, do the job and are reasonably reliable. Due to their
cost these cards were often used to provide additional IDE ot Printer ports
on machines which had only one. This was easily accomplished by disabling
all the ports which were not required.
This particular card had the following specifications;
One Printer Port
Two Serial Ports: COM1/COM3 and COM2/COM4
One Game Port
Selectable Printer Port: LPT 1/LPT2
Selectable IRQ Setting for Serial and Printer Ports
IDE Controller Interface for two hard disks
Floppy Disk Controller for two floppy disk drives (Support up to 1.44Mb)
