Could use a little help with this. I have a new 2000/Access system up
and running and have successfully loaded an account from the CSL tape so
that appears to be all good. Looking at the doc for running the
conversion program it tells me I need to load the Master Tape which I
locate without issue. The problem I'm having is to load it I have to:
1) Press HALT and PRESET
- okay not an issue following the guide gives me the commands to do
2) Select the S-register and clear the display. Set bits 15 and 0. Set
bits 11 through 6 to the low number (high priority) octal select code of
the magnetic tape device controller.
- Bit more of an issue for me as I'm not sure what value to enter for
the tape device. Looking at the included .sim files I used the DEPOSIT
command with what I thought was it and setting bits 15 and 0 as
indicated but don't think I had it right.
3) Select the A-register and clear the display. Set bit 0. Press STORE
and IBL. The contents of the magnetic tape loader ROM are loaded into
- Here it stops. The doc says to use the "LOAD CPU" command to simulate
pressing the IBL button but when I do I just get "Command not allowed".
Not sure it I even have the right value in the S-register to begin with
of course but Simh doesn't seem to want to let me "press IBL"
