Hi
I,ve only recently bought an A1200, so I'm no expert but the users guide for a GVP A1230 Turbo+ series II states "The A1230 Turbo+ can use GVP's 1MB,4MB or 16MB SIMM32 modules in any combination. When combining SIMMs of different capacities, however, the SIMM with the highest memory capacity MUST always be installed in SIMM Socket #1". I hope that's of some help.
