thanks for that nigel! just what i need to do with my 9020a, so very useful photos! i havent powered mine on yet as i intend to do some checking of psu components etc before i fire it up as it was reported as having a psu problem. might also have a z80 problem too as the legs are black indicating the typical type of corrosion seen in arcade pcbs so i'll have to pull a few socketed components for cleaning before firing it up. did you have any luck getting yours working ? and getting manuals ? my manuals (user and service) should arrive in the mail in a week or two. cheers, andy _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/
