Hi All;
Thank You, Jack for Your suggestion.. "" After all, it's summer and you must have lots of free time. ""
Not as much as You might think, there are alot of Trailer Issues, that have come up since the flood, that just now are showing up.. And need fixing and constant attention..
I Looks like the ISZ Instructions is working, I am waiting for the test to finish, to also evaluate the SZA instruction as well..
It partially has ION/IOFF working, but there needs to be some wiring changes in that section, as well as numerous other stuff before I/O would work at all.. There would need to be another Socket added for the I/O signals that would be put on the Memory Board, turning it into a Memory/I-O Board..
Kyle, Thank You for the very Kind words and information on the BSW instruction..
"" but I'm guessing you're still a few months out from having two working serial ports. ""
It shows how to wire up One Port, but NOT two Ports, it does give some hints, but nothing more..
But, at present, even One Port would be of a Great Help..
I am looking at the I/O circuit and trying to decide what I need to do and in what way I need to do it..
I have just downloaded "Introduction to Programming" PDP 8 version.. And will be trying things out with it as a guide..
I have speeded it up, I changed the 555 timer timing resistors from 100k to 10K and now to 1K, in comparison to before it is now flying..
Here are a couple of pictures..
THANK YOU Marty
