I've AGNUS 8375 and DENISE 8373R4PD originally mounted on my board (ECS chipset of the A500+).
AGNUS 8375 should be address 2mb of chip ram, so 1 mb from 2 A512 in the trapdoor is no accepted by the system?

No, that won't work.
However, I have yet another trapdoor mem expansion called "A2048" in the works that will give you the full 2MB of chip ram with your Rev.8 A500, where only very slight modifications to the main board are required. Not the "large mod" with added chips, but a few tiny things like jumper wires and cutting connections: Very easy to add, and very easy to revert as well. The expansion will go on sale either this coming week, or early January. I just need to write the instructions and make a shop page...
Ok. Thanks. I think anyway to buy 2 A512 and a RTC clock (1.5Mb chip ram is enough for me), but I will wait until I see A2048 specifications.
A2048 have an RTC clock module or an option for it?
One more question.
In the description of A512 I read that 3rd party cards can by attached to that.
The question is: if I attach my existing expansion to 1 (one) A512 with the jumper on the A500+ position, the system will see 1mb chip (0.5 on the mainboard + 05 on the A512) + 0.5 fast from my exp, or because is in the chain with the A512, the system see all the ram in the trapdoor as chip ram for a total of a 1.5mb chip ram?
The expansion (see image below) is a non original, buyed with the amiga in the '93.
If I can save some money from the ram, maybe I can buy an Indivision ECS v2 too.
Thank you for your support.

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?
Thank you
