2mb chip ram in Amiga 500 Rev 6

[bfilipe]

Greetings,
My amiga 500 (rev 6 board)is hacked to 1mb chip ram (8372A Agnus),ECS denise and kick1.3/3.1. My ram expansion in the trap door is the KCS Power PC Board rev 4.2 with 1mb.

If I replace the agnus 8372A with a 8375 (2mb version 390544-01) and socket another 0.5meg of ram in the amiga motherboard, will I get 2MB chip ram or do I have to hack the board again?

I'm unable to get the 2MB MegAChip upgrade.

Many thanks.

The Agnus 8375 I've mentioned is form Amiga 500+/600. I thought it was pin compatible with the 8372 that came on the board.

I've seen in Aminet a hack that implies making a PCB for the Agnus.

I have ram chips to solder in the empty ram sockets in the motherboard (from an old ISA vga card). But without the 8375 it's useless to put them in there.  The system already has 8mb Fast and 1 mb chip ram.

So much for the easy road...  :-(

Thanks anyhow.
