Barry,
The Insider II does not require any soldering, it just plugs in with two
jumper wires to connect. There is a 20+ page manual that describes step by
step how to install the board. The memory is true FAST ram, with the only
wait states caused by refresh collision. (very few) It uses 256Kx4 DRAMS of
any speed you can get. It'll work with 150ns chips, but they don't make the
256Kx4's that slow. A bank of 512K requires 4 chips, 12 to fully populate
to 1-1/2 meg.
Any other questions, I'd be happy to answer.
