Plan:
Each test is a set of actual instructions, followed by a jsr, and a list of memory check data.
Keep test locations in PCL,PCH.
Check data:
- zero page current/main/aux: $ff, $100
- main current/main/aux: $200, $3ff, $800, $1fff, $4000, $5fff, $bfff
- text: $400, $7ff
- hires: $2000, $3fff
- CXXX ROM: 1=c300-c3ff, 2=c100-c2ff+c400-c7ff, 3=c800-cffe
For each test:
- Test location is in PCL,PCH.
- JMP to the start of the test (we know where we're coming back to)
- end of test jsr's to CHECK
- CHECK:
- try to increment all memory locations
- pull address off the stack, so it knows where the check data is
- compare with check data
- if we get a problem:
Y=index of memory address in a table, X=desired | current/main/aux, A=actual
JMP to error routine:
- restore normal memory configuration
- save xya
- disassemble from PCL,PCH to JMP instruction
- print out memory address, current/main/aux, desired, actual
- quit test
- check rom
- if we see a problem:
Y = index of memory location
X = ROM-value
A = actual
X==A if we wanted RAM
JMP to error routine 2
- restore normal memory configuration
- save xya,carry
- disassemble from PCL,PCH to JMP instruction
- want ROM?
- yes: print out memory address, desired, actual
- no: print out memory address, non-desired value
- quit test
- increment PCL,PCH past check data
- if it's pointing at a JMP, we're done.
- otherwise, loop
* Softswitch tests
Just switch them on and off, and test each, one at a time.
