The last time I saw this thread, there was talk of Coldfire and 128Mb RAM and now it's down to 16Mhz 020 and 6Mb. I've already got a 33Mhz 020 and 8Mb RAM in my A500, so I guess I won't be getting one. I was hoping for at least a 50Mhz 030 and 32Mb RAM. Oh, the tragedy...
I was also thinking in replacing the original Kickstart with a 32 bit version (read, with 4x8 bit epros or 2x16 bit eproms), for even faster access.
Good idea. The Viper 520 card I have has the 32 bit A1200 ROMs and it is more than twice as fast as the 16 bit ROM in the original slot. (ROM on Viper is switchable)
The IDE interface should be 2.5" to allow internal 2.5" HD or CF (through IDE to CF adapter) - not 3.5".
An internal fan could be added onto it, but the 68ec020 is pretty cool unless overclocked (like in the Apollo 1220...28MHz...a bit warm to the touch).
There's no need for a fan on the 68EC020. Even after 8 hours use, my 33Mhz 020 is barely warm. (a fan in an A500? unthinkable! ;-) )
