17.006 Fattening my GS's power supply leads greatly reduced system crashes. Is there any more that can be done to eliminate glitches?

         Yes. There is another weak link in the power delivery 'chain': the
motherboard circuit traces supplying power to Slot boards are fairly skimpy,
especially on ROM-01 boards. A heavy power user, such as a souped-up Transwarp
accelerator board, in Slot 7 can produce significant noise up and down the
entire Slot 'backplane'.

     The cure is to remove the motherboard and tack on #18 - #16 gauge jumper
leads. (See Question 007 for details.)
