Hello. A500 8×44256 (1 RAM = 256 KB×4 bit) upgraded to 2×514400 (1 RAM = 1 MB×4 bit) possible? 8×44256 = 1 MB×8 bit, 2×514400 = 1 MB×8 bit. 1 MB chipRAM.
The 44256 and 514400 pin compatible, 20 pins.

I do not want to expand the memory. A500 rev. 6A, 8372A = max. 1 MB chipRAM.
2 MB chipRAM not possible, 2 MB Agnus not possible.
I want to use 2 piece 441000 chips instead of 8×44256 chips.
This possible with A500?
C64 8×4164 = 2×4464 work.

C64 wide, or Plus4 8×4164 motherboard to 2×4464 possible.
4×4164 = 1×4464, look: http://postimg.org/image/rqwr8xazd/

C128 or plastic C128D 16×4164 = 4×4464 work.

C128DCR originally 4×4464.

8×44256 to 2×441000 too complicated.

If A2000 1 to 2 MB chipRAM possible, then A500 6A motherboard 1 to 2 MB chipRAM possible.
