finding integrated circuits?

[raymond Y]

what is the proper procedure to find
integrated circuits that have the number
on them erased?

i need the microprosesor on a SRC-193
12 channel dmx dimmerpack but
when i google SRC-193, the manufacturer
of this device is nowhere to be found?

regards
r.y

Try bright diffuse light at a shallow angle, and dab a smear of white spirit
or paraffin on the top of the IC, and use a strong magnifier. It doesn't
always work, it depends how thoroughly the numbers were ground off.
