Cleaning up a Mac SE for a friend (Miniscribe didn't work anymore), got it back to work perfectly nice.
But, when I got it, I noticed an extra DB 9 connector on the back, never seen one before.
After opening the machine up, the DB9 connector was patched up to a PDS card installed in the machine.
I have no idea what it is, nor does the owner!
I know the HM53461 chip is 120ns videomemory (making for I think a total of 512 kB, but not sure), so I assume some sort of videocard for a 2nd monitor? Just no idea what monitor would use a DB9 connector!
So here goes!
