Subject: Re: Removing ROMs from Issue 7 board
Hi all
Whipping out of ROMs
I have to respond to this one.
I have extracted many many many many many ROMs from BBC's. Without fail,
the best tool I have for this job is a simple bent screwdriver. It was
bought as such by my brother for me about 40 years ago. At the time I
had no idea how important it would be to me.
It is about 4 inches long with two bent ends, each three quarters of an
inch long. One end is a Phillips style driver, the other end is a flat
normal screwdriver type end.
I gently ease the flat end under the ROM and ease it left and right as I
work my way under the ROM. I Place a free finger on the top of the ROM
to wedge it onto the driver. Sometimes, I then need to work at the ROM
from the other end too. Eventually though, all the legs break free and
the chip pops out.
At the moment, I am too busy to photograph the technique, but I promise
that when I have fininshed my local Ambulance Service torture session I
will be back in action to show you all how the professionals do it.....
