Can an A590 be upgraded to 8Mb (+ more)

[sim085]

Hello,

The GVP HD8+ cn be upgraded to 8MB while the Commodore A590 can only be upgraded to 2MB.

My questions are; Can the A590 be upgraded (through some fix) up to 8MB? (Something like the fix to add 2MB Chipram to an A500 directly on the motherboard...)?

Also is 8MB the maximum ammount of FastRAM that can be added from the side expansion slot of an A500(+)? Or there is no limit (from the A500 perspective) but no company developed side expansions which could get more FastRAM?

Regards,

Thank you very much for th answer. If I understand correctly an A590 can be upgraded to 8Mb if I find DIP20 packages of 1Mx4 but these seem not to exist.
