Tank 8 is unfortunately beyond misprint... it actually does not disclose any CPU or CPU-PROM related information in the schematics, and it does not mention the CPU structure at all in the manual. I almost believe that the game was originally constructed without CPU - given that so much logic resides in TTL format.

Thanks for sharing - Hans Andersson sounds very Swedish to me. Small country, I will try to find him he here.

Pretty cool - I did not know that Mame could work with discrete in this way. Impressive.

Btw when I looked at some tank8 rom files available as downloads I noticed that they have extension .c1 .j1 .f1 .e1 .l1 .k1 .j5 .h5 .n6 etc. Is there a file extension logic and a guide on how to inspect and use these ROM files as non MAME (or are they deeply MAME configured)?
