I have an Amiga 500 rev 8A.1
The mainboard is the same of A500+ (the A500+ logo is marked on it) with full ECS chipset, but with only 0.5MB of Chip ram and no RTC clock mounted.
With 2 A512 expansion cards connetcetd together + an RTC clock module, I should have 1.5 chip ram and a RTC clock on my amiga.
To have 2mb of chip I founded some tutorials to modify the mainbord to add the last 0.5mb, but I don't want modify my amiga.
All changes I want to do must to be reversible to mantain complete originality of my machine.
My question is: can i use 3 A512 memory expansions connected together + RTC clock module on the first exp. to have 0.5 mb chip on the mainboard + 1.5 mb on the trapdoor, or the maximum chip ram avaible is 1mb from the mainboard + 1mb from the trapdoor?
