A message to laser 128 users, you can pull the 65c02 and replace it,
but there is one side effect - the internal controller for the 3.5 inch
drives won't work right.

I called Laser computer, and they said it's probably a timing problem
due to the way everything else works fine.

I do however have a spare UDC card that was laying around, so I'm running
on a 65c802 with my 3.5 inch drive running from the external slot.

This way everything works just fine...

I made an official request that they look into it, and since its just a
timing problem (probably) it can probably be corrected by just
coming out with a new version of ROM.

How would I go about reading the Eprom in my laser, and substituting 
a different set of code for the UDC roms?  

Whatever equipment would be required, I'm sure its available around 
the school here somewhere.
