The 27C2048 doesn't strike me as being the correct model to be directly plugged into the A1200 motherboard.

I seem to remember that the 256kB chip is the 27C200 and the 512kB chip is 27C400.. So you'll need a pair of 27C200s. Also perhaps a 23C2100 can be used as the 256kB chip and a 23C4100 as the 512kB chip..

It's becoming increasingly hard to locate these chips, I'd suggest you use a modern flash part and create a personality module to plug it into the Amiga.
