Looking for an Amiga 8375 Agnus IC (Amiga 600, Amiga 500 Plus.) NTSC is
what I have now but the PAL version might work.
Also interested in an Amiga 600 motherboard, can deal with it if bad caps
and cap damage.
Thanks

I probably have one. More likely to be NTSC than PAL - I'll look. What
do they go for, these days?
Cheers

Hello Robert,
Did you find this? Eager to get back to repairing the A600. It has
kicked my butt for a long time. A friend gave me the system working and I
like it a lot, but then the caps leaked. Cleaned that up but can't get
past RAM failure issue that isn't the RAM chips.
Thanks!

It's a little interposer that allows using an 8372A Agnus. You're
limited to 1MB chipram with it, but it beats 0.

Woah! That is awesome, and I have a 8272A or two sitting around. The A600
I have has 1MB of RAM total as it is and I don't have any burning need to
go above that.
Problem though. The Amiga 600 8275 is a surface mount device, not through
hole. So no way to mount that easily.
A vendor in Germany has a bunch of 8275 NTSC chips but they pulled them
off the for sale list as they are turning them into some kind of 2MB RAM
add on for Amigas. A vendor in UK has boards that run like $40-45 that
give you 4MB, not sure if it is the same type of RAM (that chip or fast or
whatever) but it definitely gets in the way of sourcing repair parts.
