Until now I only saw an advertisement for a 6530-005 in an 70ties magazine. But today I found an ebay advertisement selling these IC’s. A Rockwell variant, date code 8114. Without any description, so the function is still unknown. But a photo is now found!

I also found more 6530 variants used in the pinball industry:

6530-12 or 6530-13 were used in the Gottlieb System 1 sound boards
6530-14 was used in the Gottlieb System 80 series sound boards.

I have added a page with photos of my 6502 systems. From the KIM-1 to the A-One extended and Micro KIM to the Pocketerm. Includes Junior and Elektuur bus systems like EC65/Octopus.

The KIM-1 has two 6530 IC’s, the 002 and 003. From some research I have found that this factory mask rommable I/O RRIOT has been produced in more versions.

An interesting one is a relative of the KIM, the Terminal Interface Monitor 6530-004. Meant for a minimal 6502 development system, it contains a teletype oriented monitor program and a serial interface via bit banging.
See the TIM 6530-004 page for more information.

But there were more 6530’s produced (and the list must be incomplete since lots of sequence numbers are missing. like 001.

6530-005 According this OSI appnote this is an unprogrammed version of the 6530. I have seen ads for this part without description of what this is.
