So, the plot thickens. That explains why my new TOS ROMs blew - perhaps.
When I replaced the old 2 chips with 6 new ones, one (or more) of the new
ones blew. And everything worked okay again with the old ones.
And at the time I thought logically that increased power drain meant
lower voltage, and therefore lower current per chip. The note this
note follows explains that actually a higher power drain means more
current per device. I hope that this new engineering concept will be
explained to novices like myself in due course. How can the MMU be blown
by extra chips on the board???
Respectfully, ak.
