SOP28 330mil programme adaptor? - UK Vintage Radio Repair and Restoration Discussion Forum

HI,
I have a bunch of 8kx8 memory chips in an SOP28 package that are of unknown history and so I'd like to test them out before fitting (to a Tek 'scope).

I am the happy owner now of Stephan's amazing Chip Tester Pro but I need an adaptor that will allow me to plug them in to the zif socket.

These chips are wider than the normal SOP28 at 330mil and I just can't seem to find an adaptor for this package size (at least not at at hobby level price).

I have gone through pages of listings on Aliexpress and found the odd one that lists 330mil, but checking the detail find they are really 300mil versions. (any size from 28 up to 44 will fir the tester)

Anybody know where I might get my hands on one?

Thanks,
Ralph
