R6530 005 013 014
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.

Gallery of 65XX IC photos
My drawer is full with a supply of 65XX IC’s. Some bought, some donated, some salvaged. From old to quite recent.

65XX IC’s
In my boxes with electronic parts I have many IC’s. Partly new bought, lots also rescued from obsolete boards. The 65XX parts present a large part in the microprocessor corner! Recent inventory revealed some unique and older types. So here I present photos of unique 65XX IC’s in my collection, duplicates left out.
Some older ceramic IC’s are from photos from other sources, like the Jolt archive.
MOS Technology dated the IC’s with the number string WWYY, where WW is weeknumber padded with zero, and YY are the last two digits of the year.
Example is my oldest part is 6530, date 1476 white case, stamped week 14 year 1976. The youngest parts are Rockwell R6522s from 2007! And the 65c102 dates 0843, which means 2008?
Other manufacturers reversed week and year, like the 6507 8222, year 1982, week 22.

OSI Model 300 trainer
For a long time I have been looking at the photos of this, o so simple 6502 trainer, to see how it works and be able to build one myself.
Now that the circuit diagram has become available I have added a page on the OSI 300 on what I have found out about this simple 6502 system: photo’s, manual and circuit.

My 6502 systems
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.

6530 6532 TIM 6530-004
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.
