Can someone tell me about the different CPU upgrade options for an A1000? I was told that a 68010 is the only thing available for the A1000 -- something I find hard to believe. thanks, /laura

But, CSA and others do make accelerators that work OK in the A1000. I believe many A500 accelerators will work in the A1000 as well.

Several accelerators have been marketed for the 1000, along with the public domain design for the Lucas/Frances 68020 boards from Brad Fowles. Two that come to mind are: a) The Ronin Hurricane 68020 and 68030 boards. They have been available at 14 MHz and (I believe) 28 MHz. I am in the process of buying a used one; I don't know if they are currently marketed by Ronin. It can hold at least 4 Meg of on-board 32 bit DRAM, and 0.5 Meg SRAM. I am told it simply replaces the 68000. b) The CSA Mega-Midget Racer, available in speeds up to 33 MHz (at least) with a 68030. Can hold up to 4 or 8 Meg of on-board 32 bit RAM. Requires that your 1000 be modified to boot from PROM, and has a bit of a space conflict with the 1000 floppy drive, which can be fixed by getting a slimmer drive, or booting Workbench off an external drive. CSA also marketed other boards for the 1000 (such as the "Midget Racer", hence the wierd name "Mega-Midget Racer" for the newer board). Brad Fowles used to sell a kit with PC boards and parts for the Lucas board, but no longer does. The design is in the public domain, however, and you can use it to build your own boards if you'd like.
