And one thing to dislike, although maybe not, if that slot can hold a suitable dual parport card such as I have in the existing system, thinking of future expansion. ;-) Has anyone simply snipped the db25 off a parport cable and crimped a 26 pin header to the ribbon in order to connect to the onboard parport header? I used such a lashup years ago to drive a parport printer from a side port on a floppy controller plugged into a coco, but then the commish came around and said we were making too much noise, so all the printers got noise filters on their inputs, and the coco didn't latch or handshake the data, so if the printer didn't get it in 450 nanoseconds, it missed the character. I may even have that cable rolled up in a box yet. >From db-25 to a 26 pin header, it was a direct pin for pin connection if the header wasn't plugged in bass ackwards. But I just traipsed down to look for it without finding it. :( > Keep on truckin' ! > > Regards, > Kent Thanks Kent. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
