The current Quickstart Configuration layout for A500 model looks a little messy in comparison to other model configuration layout ... see on pic. attached below.
The proposal would be to rearrange it to something maybe like below:
(instead of dash could be maybe made some small gaps)
1.2 ROM, OCS Agnus, 512KB Chip RAM
1.2 ROM, OCS Agnus, 512KB Chip RAM + 512KB Slow RAM
---------------------------------------------------
1.3 ROM, OCS Agnus, 512KB Chip RAM
1.3 ROM, OCS Agnus, 512KB Chip RAM + 512KB Slow RAM (most common)
---------------------------------------------------
1.3 ROM, ECS Agnus, 512KB Chip RAM + 512KB Slow RAM
1.3 ROM, ECS Agnus, 1MB Chip RAM
1.3 ROM, ECS Agnus, 1MB Chip RAM + 512KB Slow RAM
As you already noticed, I have also added a new config. with ECS Agnus 1mb + 0.5mb, as there exist some programs that need it f.e.:
At the Party (40k Intro) by Coma & Bigmama ->
http://janeway.exotica.org.uk/release.php?id=295
Also, such configuration is probably nothing unusual to find on an newer A500 that was already delivered with 1mb chip ram and additionally expanded with 0.5mb slow ram.
ps.
Anyway, by mistake in current layout there is missing word "Agnus" at the most common configuration!
