I have never been able to wrap my head around the pattern error.
The long test is looking for pattern sensitive errors (nearest neighbor). What happens if you LOOP (see 4H-11 in the operators manual). I've seen similar on a (non arcade) board with a bad bus transceiver but it can also indicate a fault in the RAM itself. _______________________________________________ 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/
