Anybody remember USES of the SIXTH ROM socket?
Sorry no
"MBI" (probably a different MBI) made a
supplement ROM that added
some printer configuration features, etc.
I think that there still is one in my 16K 5150
Such a big market for them old printers these days (ok a plotter is a sort of printer and
the only way anyone's getting mine is wrenching it from my cold rigor mortised
embrace. And would you believe I only payed 5 clams. How much joy can you get for 5$ these
days???)
Other "non-standard" ROMs:
Todd Fischer? made a diagnostics ROM, to temporarily replace the BIOS ROM,
and communicate through the serial port!
Ooh gimme dat! I want one seriously. What's his phone number?
ROM monitors are standard on many Japanese puters, Canon, NEC.
Just can't find any docs :(
You can pop the hood and put in a new chip. But what about an extension via the all too
popular casette port?
