[dadstoy]

I have and a2000 Rev 6.xx. I have no fast ram, 8-c4256 chips onboard.

Jumper settings are:
J101-2 & 3
J102 -solder jump to left of CPU slot
J200-2 & 3
J300-1 & 2
J301-Closed
J500-open

Any help would be appreciated.

Isn't the Rev6 A2000 1MB Chip? So if you have no additional memory installed, none will show up, right?

Not sure.
But now that i am thinking about it, you might be right.

Rev 6 is certainly 1MB chip memory, it should have the 8272 Agnus.
There are enough expansions to get your A2000 up to bigger numbers https://www.amibay.com/threads/dick...r-card-for-a2000-amiga-official-host.2443695/
