SWTPC 6800

I think for me what gets confusing is where the various pins are. ?I have to read and re-resd pinouts to figure out where stuff should be. ?I sometimes have a brain fart and get it backwards. ?Yesterday part of my problem with my Tektronix box was having the numbering of pins on the terminal's DB25 backwards. ?Once I had that figured out it was just a matter of looping certain pins and we were good. ?It just adds an extra layer of fiddling. I have a question though.. there have been a few times where I thought the 6800 crashed but may not have. ?In several cases.. I sent a large loader file across and noticed errors coming through.. so I'd stop the machine. ?This was after teraterm said it had sent everything through. ?Is it possible the serial port on my PC is still trying to send out garbage for a while, messing up my connection to the 6800 until it finishes? ?I kept moving cards around but eventually it seemed to start working after so many powerups and time had passed..

The 75 wasn't readily accessible, I had to go to a low level in the unix config code and try sequential factors in the configuration for the rate, 75 being another factor of 2 down in the standard rate series 19,200 . . 9600 . . 1200 . . 300 . . 150 . .
