Some other front panel uses – Memory sizing, memory testing – writing known patterns to memory and reading them back (or not) Peripheral/UART testing – reading/writing control and status registers, terminal i/o BIOS configuration – build BIOS in RAM, jump to warm/cold start address Code verification – single stepping through code loops, etc. Verifying machine state, processor status, interrupt condition, flag status, etc. (depending on your front panel)
Obviously, much of this could be done with a ROM monitor as well, assuming that (a) you have a ROM monitor and (b) you can load it into memory. Probably lots more, but that’s a pretty good slice – Jack From: [email protected] [mailto:[email protected]] On Behalf Of nbreeden Sent: Saturday, February 08, 2014 11:31 AM To: [email protected] Subject: [N8VEM-S100:2368] Switch Register My system is old enough it has a switch register on it's Front Panel - I have a few questions. - It's on port $FF - is this the correct port for the SR - for some reason I remember it being on $FE? - I find it useful for debugging (writing bit patterns to the SR) - Does anyone else use one this way? - Are there other uses for the SR? -Neil -- You received this message because you are subscribed to the Google Groups "N8VEM-S100" group.
