I have a Rev 4.2 A2000 with the 1 MB Fat Agnus, Micron 2 MB memory board,
1.3 ROMs, and a Microbotics Hardframe for my Rodime RX1500 SCSI harddisk.
Runs great, absolutely no problems, except that I have to set Maxtransfer
to 65536 (64K).  A Maxtransfer value of 128K caused R/W errors to
consistantly appear when I ran DiskPerf.  I haven't the faintest idea why.
DiskPerf still gives me 600 K/sec R/Ws though, and I have not experienced a
single R/W error (besides the initial ones) since installation in November.
