Hello there...
I just did the jumper/cut mod on my rev5 A500 for 1 meg chip ram out of sheer boredom and much to my dismay it worked when using the stock 8370 Agnus.
Well, it worked until I ran an old version of octamed, which crashed almost immediately. I decided to pull the 8375 Agnus from a broken a600 and try to "plug and play" but there was no screen...just black. I did some reading and I see that it should just work:
http://www.amigau.com/natamiga/t-agnus-installation.shtml...but it does not. Is there anything I might be missing here?
Also, the site looks great!
