6530-004 $7000-$73FF TIM Terminal Monitor, see the TIM page
6530-005 According to this OSI appnote this is an unprogrammed version of the 6530 TIM
I have only seen ads for this part without further description of what this is.
It has the 16 I/O lines, 64 word RAM and the timer, which can generate an IRQ. One can assume the ROM is empty.

Replacing the 6530-002 and -003 in a KIM-1 has become quite easy. See this page on replacements with a 6532, some glue logic and a (E)EPROM.

The RRIOT in CBM disk drives are only different in the ROM contents The rest is as follows:

– Pin 18 is PB6 (no CS1).
– Pin 19 is CS2 (noPB5) .
– Pin 17 (PB7/IRQ) has no Pullup.
– ROM is in $FC00 bis $FFFF (RS0=0, CS1=X, CS2=1).
– RAM is in $0000 bis $003F (RS0=1, CS1=X, CS2=0, A9=,0 A8=0, A7=0, A6=0).
– I/O is on $0080 bis $00BF (RS0=1, CS1=X, CS2=0, A9=,0 A8=0, A7=1, A6=0).

Logic of addressing:

 	RS0	CS1	CS2	A9	A8	A7	A6
ROM	0	X	1	-	-	-	-
RAM	1	X	0	0	0	0	0
IO	1	X	0	0	0	1	0

Via an adapter board Commodore reused older 6530’s with new firmware by disabling the built in ROM and adding a 2716.
See Zimmers Commodore archive. Note that not just any 6530 can be used in this way, only the 6530’s from the Commodore diskdrives. A more general approach with a 6532 is described here.
