I recently acquired an unmodified NMS 8250. I'd like to expand the RAM a bit, and I'm not affraid to handle the solder iron (I successfully chipped a PlayStation2, those IC contacts are really tiny!).
Problem is: I do have some 72-pin SIMMs, but I have no idea if I can use them in my MSX. They contain the following memory chips:
VG2618165BJ (42 pins)
HY514404A (20 pins)
Any thoughts on this? Your input is greatly appreciated!
