Snap-On scanner E-prom

[Karl Hafen]

        Hello I've been reading the list for a while now and, while it is a bit
off the subject, I've got something I am curious about.  We just bought the
update
pack for our Snap-On MT-2500 scanner.  This consisted of two E-Proms.
Pealing the 
labels off the old proms revealed the following markings.
On the 28 pin:
PGM=12.4v
b9412al
NMC27C64Q
200

On the 32 pin:
M27C401
-F1
V88AD
9348CS
SINGAPORE

        My question is are these common parts that can be read with a prom
reader
and stored on disk, or are they proprietary Snap-on only units??

Thanks
Karl Hafen
