Does work great but I like the kind that allows you to stress DRAM by
"overclocking" beyond it's speed rating by twisting that knob.
Example, that part fall over at just 3ns over rated speed, naah
plonk! It will fail running warm anyway when machine is closed up.

Only limitation it only works w/ 256K and 1M, 1 bit and 4 bits.

Cheers,
