Sorry folks. I have done my best to locate these chips and come up
with a big fat zero.

I had three hopeful sites had them listed in there search engines.

They either didn't return my repeated emails or they said nil stock.

Can't help feeling Wayne should have made his order a little bigger
than just 160 spares, when he went back into production, for the MM
remake.

Anyway good thing they are very reliable I suppose!

For those who missed my first post or is just plain wondering what I
am talking about.
The ASIC (Application Specific Integrated Circuit) is the Square 84
Pin CPU chip on all Williams/Bally pinball machines CPU boards made
from 1990 to 1998. It was mainly produced by Motorola for Williams/
Bally and it contains Williams 11 different herbs and spices.
Motorola's part number is S38FC049PI03.
Williams part number 5410-12426-00.

Cheers Busby.

Could have been worse, one of those guys could have taken money off of
you.

That part is astonishingly old for a custom chip that still changes
hands for money. I'd figure it as a 1 micron process device, and
probably full custom because it contains a real-time clock. So it
won't have any programmable elements.

I don't think that there is a whole lot in there, it is mostly
displacing TTL logic from the WPC board. The 6809 processor is now
available (for download) in design code that can be loaded into a
programable logic array, with a ton of space left over. One day, some
enterprising soul with time on their hands will no doubt jam all of
the WPC digital logic - CPU, sound and video - into a single FPGA.

I've done something similar to this. I have compiled a complete Gottlieb System 80/A/B to fit within one FPGA. This includes the 6502, three 6532's, all glue logic, ROM's, and selectable display interface (80B) -- all within a single Xilinx Spartan 3 FPGA. Too bad these don't come with a bank of NVRAM within them...
Had it running Gottlieb's Ice Fever code for awhile.
