PH00524, but emulated
|

|
When troubleshooting the PH00524 evacuation controller board it's useful to be
|
||
|
|
able to tell what the microcontroller _should_ be doing, rather than just
|
||
|
|
staring at disassembly/decompilation all day long.
|
||
|
|
|
||
|
|
This little program executes our scope evacuation controller's code (from the
|
||
|
|
U12 EEPROM) in an environment consisting of a Z80 CPU and all peripherals
|
||
|
|
required to reach a pumpdown state.
|
||
|
|
|
||
|
|
It comes with a little text UI interface:
|
||
|
|
|
||
|
|
Controls: [v] vent, [p] pumpdown, [q] quit
|
||
|
|
PC 02bc
|
||
|
|
---- -------- VENT
|
||
|
|
M1 M2
|
||
|
|
|... ..
|
||
|
|
|
||
|
|
This shows the controls (keyboard buttons v, p and q), the last program counter
|
||
|
|
at which an I/O operation was performed, indicator values, motor movement and
|
||
|
|
lightbarrier status.
