Found an old fax machine today with a NEC V55.
+ a TMS 27C240-10 UV eprom.
Should I throw it out ?

NEC V55 sounds interesting! What`s the exactly P/N
of this chip? I didn`t know NEC produced V55`s....
What package? Could you take a picture? How much?

Oh no, too bad!
Did you use a heating
air-blower?
Because of those accidents
also happened sometimes to me
I now use a saw! Sawing the
PCB with a little border around the
chip does not look bad.
It is a bit more work but there are
no bent or missing pins anymore and
you can store the chips easily because
no problems with bent pins.

Oh well...
At least it's nice to know they made that package "v55" .
