Dear all,
New to the forum and new to Mame.
I have for some strange reason of later years gotten into the pleasures of transferring TTL only arcade schematics into FPGA - to understand how it was all done without CPU, for the fun of it, for game preservation purposes and for those arcade owners who cannot bring their old PCBs back to life or who have empty cabinet (non profit of course).
So far I have worked on Computer Space (complete), Monaco GP (sound still missing), Indy 800 (sound and some crash logic missing - but Sprint drone car logic added) and GT10/LeMans (crash and sound missing).
I was asked to look into Tank 8 - which according to the operations manual and schematics is all TTL, but when I look in the parts list it features some PROMs and a 6800 CPU. The PCB layout in the manual also shows the PROMs and 6800 positions. Quite strange actually.
I quickly noticed that Tank 8 had been released on MAME (cool - since quite some logic and sound generation is TTL only), which is why I turn to this forum. If anyone has some interesting insights to share I would be very happy.
