When I got the TOS 1.4 installed - all hell broke loose - bus errors, random bombs, etc. Spectre GCR was unuseable. When I had the 4 meg upgrade done they aslo replaced the two LS 373 chips with AS373 chips. Since then the machine has been 100% without a bus error to be seen and Spectre GCR is 100%.
