The rom in that pcm, is a flash prom.  It's accessed thru the ALDL
connector.
Is very difficult to work with.   Only flash stuff I know of is $$$$.
Grumpy


| OK, the ECM I havBSCSKe in my lap is marked with the service number
16214399
| BSCS.  It also has the additional code *86BSCSK262212TF3*.
|
| There are four plugs marked BLACK, RED, GRAY, and BLUE.  In fact the plugs
| themselves are these colors too.  On the side opposite the paper label,
| there are two sensors (I would guess barometric pressure) mounted on a
plate
| that is affixed to the case.
|
| The case has hex / internal star screws holding it together.
|
| I have read the DIY/EFI site and cannot find anything as to how to proceed
| to read the rom.  Any advice would be appreciated.
|
| I will be happy to share all I glean form this ECM and can put pictures in
| the in box also if anyone is interested.
|
| TIA,
