Hi everyone,
Just finished moving my working MegAChip from my A2000 to my A500. My A500 is a vanilla A500, Rev 5 board with 512KB Chip and 512KB Fast. I cut the JP2 linkage and soldered the bridge towards the top direction of the machine and cut the trace running along the CNX memory connector as shown in the manual. All works good and I see 2MB Chip RAM now.
My question is, why can't some of the memory either the onboard 512KB or the 512KB in the memory expansion connector be used as memory to top up the Fast RAM? I now get 2MB Chip RAM but absolutely NO Fast RAM at all. Is there a hack or something to use some of this RAM as Fast? Before the modification I had 512KB Fast RAM and it was working correctly.
Another question is, does having no Fast RAM in an A500 affect anything in terms of games not working etc? If I left it with just the 2MB Chip and not having any Fast RAM, would I ever get games refusing to work or other problems down the track? Are there known games that refuse to run if an Amiga has no Fast RAM?
Any information would be greatly appreciated. Cheers
