MOS 6530 IC chip

I am not an electronics guy. I am a pinball guy. There were several models
of pinball machines that used a MOS 6530 IC chip. these chips are not made
anymore and cannot be found, i am told-

here is a link to the chip- http://home.hccnet.nl/g.baltissen/6530.htm

Does anyone know where there might be a stash of these chips as used in
Allied Leisure CPU boards?

Could anyone out there reproduce these chips or a suitable replacement?

Thanks!

It's got masked ROM in it, so unless you can find a replacement intended
for the equipment, you're out of luck.

It's got 2 8-bit I/O ports, 64 bits of RAM, an interval timer, and 1K of
ROM.

Now, the ROM may just be ignored in this case, but there is the 6532
that is the same thing (I've not checked the pinouts to see if they
are identical), but minus the ROM, so if someone was just using the
I/O it would make sense to use the 6532 rather than the 6530.

If the ROM is not being used, the workaround is to build up
the various parts using other components. I'm not sure how the Mos
Technology's later I/O ICs match the I/O in the 6530.

The 6530 was used in the Mos Technology KIM-1, and so one can find
information about the IC (and maybe workarounds) by searching on the
KIM-1.
I seem to recall there was a site about making your own KIM-1, and that
is very likely to show how to workaround the 6530.

as far as the masking goes, how do you tell one 6530 from another?
what are the distinguishing marks?

joseph-


Any distinguishing marks will be obscure -- lot numbers, date codes and

the like. If you want to replace the chip you need to use exactly the
same chip to replace it -- and that probably means that it at least come
from another CPU board just like the one you want to put it into, if not
one from exactly the same game.

The 6530 contains masked ROM code which is almost certainly specific
to the game, so you can't use just any 6530.

How much money is in it? I could certainly fabricate plug-compatible
replacements if you have a working chip from which the ROM code can
be read. It would need a small FPGA and configuration memory on
PC board with the 40-pin DIP footprint.

No, the 6530 and 6532 have quite different register and bit assignments.
 
Great- the three chips in it are all different-
anyone out there able to point me in the right direction to find the meaning
behind the markings?
the three in my machine are all MOS- one has a logo, the others say MOS.
a friends' machine, also not working, has two rockwell chips and one MOS.

thanks-
