Hello, was reading the Wikipedia page on the A500+. Here, in the specifications section, I found the following; "Memory: 1 MB (9.5 MB maximum)". Now, from the little I know, an A500+ can have more then just 9.5 MB of RAM. Then what is this referring to? Maybe only ChipRAM? If yes, is this so, and why?

It's wrong.
The A500+ comes with 1mb onboard & can have an extra 1mb in the trapdoor. Without a CPU upgrade it can then have up to 8mb on the expansion bus. Which brings the total to 10mb.
With a 68020+ CPU upgrade you can have more (the space between 0x10000000 & 0x80000000 ~1.75gb is probably free).
Officially the original a500 is limited to 9mb, 512k onboard, 512k in the trapdoor and 8mb on the expansion bus. However I had a 2mb agnus which still allowed the trapdoor expansion to be used. IIRC I had 2mb chip, 1.5mb in the trapdoor, but only 2mb on the expansion bus (might have been 4mb but it was expensive ZIP ram and I don't think I could afford it at the time).
