This 1.8 meg will always be on the AGNUS BUS, and therefore be slow! because the CPU will have to acces it trough agnus. Although it will be called FASTMEM (just as regular C00000 memory). External memory is cheaper(if you have, or will get a harddrive), and faster. Also external is expandable with cheap, fast, SIMMS. Nils Gokemeijer (NJ_GOKEM@FANDM.BITNET)

This 1.8 meg will always be on the AGNUS BUS, and therefore be slow! But this is exactly what you want when C= release the 2 meg Agnes. Take a look at the memory map in your owners manual. The first 2 megs are CHIP ram. All that's left is for C= to start making Agnes with a 2 meg address space, instead of the current 1 meg Agnes. I would have replaced the 256 x 1 Kbit chips in my A501 with 1024 x 1 chips over a year ago if it hadn't been for the fact that the chips in the A501 had a "non-standard" number of pins. The thought of all those bus contentions doesn't bother me as I don't need maximum performance, just lots of memory :). PS. I'm still waiting to here from people running news and/or telnet on their amiga.
