Anyway - the posted code is an example of what I'm trying to start with for building the rest. ATM, this is just an example and for purpose of this discussion I'm just trying to figure out the basics of:
- Basic type to be able to easily put common 30-bit value into memory
- Basic type that when getting from memory, can easily be converted to a data word/instruction word/packed character set
Note: the packed character set as described is the way the computer was originally programmed since the output would have to be converted to either:
- send text to 5-bit teletype
- Send text to PPI (plan position indicator - aka radar repeater) (30-bit word)
- Send text to auxiliary CRT (15 lines X 65 character text only) (30-bit word)
The PPI and auxiliary CRT both actually use the same channel - the only difference is the 30-bit word format.
