The following is a list of known bugs and quirks discovered through analysis
of this computer and it's hardware.


#1: Undefined motherboard I/O ports can return seemingly random data
====================================================================

Description:     I/O reads on motherboard I/O port ranges, 0x00-0xFF
                 or any of it's alises at 0x400-0x4FF, 0x800-0x8FF,
                 etc. can sometimes return values other than 0xFF if
                 the I/O port is not recognized.

How to reproduce #1 (How this bug was found):
		 Bring up DOS debug and use the "I" command to read
                 port 0x92. Observe that it is 0xFF. Repeatedly type
                 "i92" again and again. Observe that the value is
                 normally 0xFF, but sometimes comes up as 0xFD, and
		 even less likely, as 0x07.

How to reproduce #2:
                 Use DOS debug and repeatedly dump other undefined
                 I/O port ranges such as ports 0x24-0x3F, 0xF0-0xFF,
                 etc.
