did anyone actually try this MPS6550?

Hi all,
I've seen this on ebay:

https://www.ebay.it/itm/MPS6550-Semiconductor-MAKE-Generic/173533300388?hash=item28676406a4:g:OR4AAOSwamhbmo8W:rk:2:pf:0

no pictures... 57 sold...
I wonder if someone on this list actually bought one and can confirm
it's the real 1kx4 2001's SRAM.
A friend of mine did buy a few HF mosfets from littlediode some years
ago but they were fake devices.
Just checking, my 2001 could like to have 8 more 6550s if those are not fakes :)
