Besides connecting a 6530 to a 6502 system, as is described in the other pages, a simple and effective test and ROM dump can be done with the wonderful Backbit Chiptester Pro V2.

This device van help detect problems with a large number of older ICs. And dump the contents of ROMs Especially the 65XX tests and ROM dumping have served me very well, e.g. the KIM-5 ROMs 6540 were read out with this device.

It can also check the 6530 RRIOT. My collection of 6530s has the KIM -002 and -003 and those tested fine. Initially the other 6530s tested with problems at Port 2 (the PB0-7 I/O pins).
Now port 2 is special since the mask programming allows to choose between CS1 and CS2 or PB5 and PB6.
The support of the Chiptester Pro is excellent and after some discussions with version CTPro-5.0.5 all 6530’s test fine. Alas the ceramic 6530-002 4576 has a defective ROM.

I have tested the following 6530’s

– 2x MOS MPS6530 002 0880 4576
– 1x MOS MPS 6530-003 0680
– 1MOS 6530-004 2576 and 5x SY6530-004 7935D
– 2x MOS 6530-005 3676 2876 and 1x R6530-005P 8114
– 1xR6530P 3004 -11 7925
– 3x MOS MPS6530 024 2081

and all ROM dumps were fine, confirming the ROM dumps I have were indeed he correct ROM dumps.
