BG> What's the story with EPROM copying these days,

The same as it's always been.

BG> do you need highly specialised equipment, or what?

Depends on what you consider "highly specialised".

BG> The Sportie's EPROM appears to be a fairly standard 256Kb job, and
BG> I wonder, do they generally copy first time, every time without any
BG> problems?

Hmmm...The EPROM in my Sportshoe is in a PLCC package and I don't
have an adapter for it. I can blow standard DIP packages but not
PLCC. Dieter used to have a gadget which would do PLCC stuff until
he told them where to shove it. (Some people, no consideration for others)

BG> Also, can they be altered slightly, if required?

Not a problem, provided you know where. Some are checksummed though
and they can hide the checksum in a weird location which can make
it a tad difficult.
