IIRC, 1K*8 SRAMs, something close to Jedec pinout (like most EPROMs).

They were used in the Nascom (at last the Nascom 2). In fact at one point 
there was a shortage of said chips in the UK, so Nascoms were sent with 
the bare minimum of such RAM (I think just the RAM for the video 
circuitry), but with a 'free' 16K DRAM board.
