All,
It has been suggested to move Tank 8 into an FPGA implementation.
I have now looked at the manual that is available here: http://www.arcade-museum.com/game_detail.php?game_id=10025
Reading through the manual and browsing the schematics it appears to be an all TLL - no CPU construct. However, looking at the parts list and PCB layout in the manual it is evident that this game uses a 6800 CPU and some game PROMs. But there is not a single trace of how it is all connected in the manual's text or in the detailed schematics (compared for instance with Ultra Tank).
I also quickly discovered that there is a MAME version of Tank 8 – which indicates that Tank 8 is CPU based.
My ambition has always been to do non-CPU games only – mainly because they are difficult to replicate in MAME like environments and don't require me to emulate processors. Still, Tank 8 has a lot of logic in the TTL domain including TV graphics so it is in a grey zone and could make sense to transfer to FPGA.
However a couple of key items are required:
1) The full manual and schematics – anyone?
2) The PROM's contents (graphics, decode, 6800 program code) – anyone?
3) An FPGA/vhdl version to emulate the 6800 processor – should exist; otherwise I just have to read the 6800 code manually and create an fpga version of the code without the need to emulate the 6800 processor (maybe a better option)
4) Someone who is interested in deploying the Tank 8 implementation in a real cabinet
