- OK, the Apollo is fast and has two SIMM sockets. If you put in two SIMMS,
- you won't get a contiguous memory block, something to keep in mind if you
- were planning to use it with e.g. ShapeShifter, you'd still need a large
- SIMM. Also beware that some Apollos have overclocked CPUs (33 MHz running
- at 50 MHz). I've got one of those and hasn't given me problems, but I do
- have a cooling fan attached to it. Finally, the Apollo A1230 has built-in
- SCSI, however, I am having lots of problems with it (and I'm not the only
- one). Make-up-your-mind-time, bit like blind date (this is just for UK people).
