It’s big, black and squared.We are talking of the ’85H001′, a custom IC you can find on some arcade PCBs manufactured by Capcom like Ghosts’n Goblins, Legendary Wings, Section Z, Trojan, Gun.Smoke.It looks like a module with audio functions, two versions have been made.A ceramic unmarked one :

And a plastic/epoxydic one marked ’85H001 5H’ or ’85H001 5I’ :

Technically speaking the ’85H001′ can be considered a nearly complete digital sound system, all typical components (CPU, RAM, address decoder, etc.) are embedded into it with the exception of the ROM and synth ICs which are external.Actually the ’85H001′ has been already reproduced by ‘Apocalypse’ who made an excellent thru-hole version :

You can read more about in his blog :

Having found recently  a bootleg of Ghost’n Goblins with a module replacement I decided to make my own reproduction and I made two versions.An ‘hybrid’ one with thru-hole Z80 CPU/RAM and surface mounted ICs  :

And a full SMT version with Z84C0006 CPU (PQPF44 package)

Here’s final testing of both on my original Gun.Smoke PCB:
