I am not ruling out a bad BMDC board, as problems tend to come in 2's and 3's, but this machine was running fine until the KB interface error popped up and there is visible damage from battery corrosion on the motherboard. The corroded battery is right beside the keyboard connection, so that all makes sense. I don't think that a BMDC problem would affect my keyboard interface. Plus, with the replacement motherboard on, the KB interface error has gone away. My hope is that by running the B3T tests we will get some more incite.
I ran the B3T.exe tests this morning that Machintek said I should run. I set the program to run 3 times. It looks to me like I have a Address problem? While running the test I got this message.
BMDC3 dual port memory failed AT side address test
AT address 800
Data should be 0800
Data is A5A5
Test summery was as follows:
Register test Error log Iterations =3
Lo address register errors=0
Hi address register errors=0
Both address register errors=0
Dual port memory test log
AT side errors=3
BMDC3 side errors=0
BMDC3 read AT write =0
BMDC3 main memory log, Test iterations=3
Read/write errors=0
UART test error log, test iterations=3
UART teat=0
Analog test error log, test iterations=3
Analog conversion errors=0
Load & run errors=3
