[sdiy] 27C512 not Eprom?

[Theo]

So these are Eproms in a window less housing = OTP,
guess it makes sense from a economic perspective.
Well too bad :(
I didn't pay for the junk box and there is some other useable stuff in it :)
Like assorted unused 74xxx IC and a almost full reels of 1uF and 100uF 50V
elcos.

I probably gona ask for some part number help again,
cause there are also some strips with weird ICs and uC stuff.
The uC are probably OTP too, but think its worth to check before I junk
them.

Mean while, anyone got a idea where -48V to 5V DC/DC converters are good
for? (got a "view" of those too)

Thanks to those who answered.
Theo
