On my homebuilt computer quest.......
There's two groups:
Built in video and serial i/o to terminal attached concepts.
Can you explain the process to "init" and operate video chip based
on 6845 chip with own ram ? Possible to use SRAM with it?
Is there CPU specific limitations?
I have many of them and certainly get put in use on computer.
And alteratives:
How one place characters on terminal, give examples of terminal
coding as sent from computer to terminal?
-outputting characters to screen?
-resetting cursor to different places?
Which CPU is very friendly for creating basic codings to put into
ROM and assembling? Z80? or suitable CPU?
Thanks!
