The TIM-1 IC is a 6530, and since the 6532 is nearly identical with regards to I/O and timer facilities it is possible to construct a TIM system with the same software.
And that is what Peter Renaud has done. He took a 6532, a 6502, an EPROM (as replacement for the mask ROM in the 6530-004) and some RAM, some glue logic to build a system. See the cicuit diagram and source below (reproduced here with his permission).
TIM-2 assembler source
Adapted for other I/O RAM and ROM addresses, functionally identical to the TIM-1 source.
Changes are (besides some assembler related)
– I/O base TIM-1 = $6E00 TIM-2 = $6800
– ROM start TIM-1 = $7000 TIM-2 $F000
– 64 Byte monitor reserve area TIM-1 $FFC0 TIM-2 = $6000
– TIM-2 no INT Vectors area
– RS232 bit inverted
– 7 bit ASCII forced
