- Extra mouse
and keyboard (non-standard connectors)
Since I lack a mouse for mine, can I put in a plea that whoever does
adopt this system consider selling / trading me the mouse? 10 years ago
I have -- somewhere -- an IBM optical mouse. I know nothing about it
other than it's 3-button, and IIRC the cable ends in a DE9 connector.
Inside is a microcontroller (8051). and not a lot else. I think I once
traced out some of the wiring back to the DE9 and came to the conclusion
tha the microntroller ran between the -ve supply line and something 5V
positiove wrt that and there was a transsitor buffer to make the output
RS232-like.

Amazingly I've found it. The label on the bottom says :
IBM
MOD 5277-1
MODEL MOUSE
MFD BY SUMMAGRAPHICS CORP
FAIRFIELD CT USA
It also says FCC IDD : BY78SDMOUSE
I am not going to type out the FCC notice or attempt to reprocude the
barcode, but under the barcode is the stirg 71B35021819109
The connector is a DE9 with pins 1 and 3 mising
Philip, if you think this will work on your 6150, you are welcome to try
it. I don;'t have the mouse pad (and as I said it's optical, from the
time when you needed a special mouse pad for optical mice), and it is, of
course, untested..
