Amiga 500 Rev 5. and ECS chip set...??

[LoadWB]

There is a little "hack" to get the 1MB Agnus installed (cut a trace near Agnus socket,) and a wire jumper to get the larger ROMs working.  As well, a Super Denise is compatible.  I did all of these.  As I recall, the information for doing each (with the exception of the Super Denise, which some will argue is unecessary) is on AmiNet.

Happy Hacking.

As far as new screen modes, doesn't Super Denise also provide EHB?  I think that's why I upgraded, EHB for some game (Death Mask?  Don't really remember now; it's been about 14 years.)

1) Bend pin #31 up 180 degrees & solder an insulated wire connecting it to pin #21
2) Solder an insulated wire onto pin #1 that terminates into the socket where pin #31 would've gone.

Dear, God, PLEASE don't do this with the ROM.  Go pick up a 40-pin DIP socket to modify.  I never understood why people would recommend doing mods with the actual chips, like the stereo SID upgrades.  If you're in the 'States, you can still pick up the socket at most Radio Shanty stores, or you can order from Jameco, Mouser, etc.
