I have a few questions targeted at owners of GVP 33mhz & 50mhz accelerators.
I just received my 33mhz settup today via fedx and to my surprise the
board said 50 mhz and had 60ns Ram.. It does however have a 33mhz CPU, FPU,
and clock crystal. I heard a viscous rumor that many 50mhz versions use
a 33mhz 68030.. Can anyone confirm this? Because if that is true, I can
upgrade to a 50mhz amiga for the price of a 50mhz clock crystal..
Second question: can any one please give me Diskspeed3.1 or Dperf2 results
from their IDE drives? I did not get my system with an IDE hd because
someone told me his IDE drive only achieved 300k /sec and was not reliable.
I find myself looking for more HD storage and thus I am considering an IDE
over another SCSI if the GVP AT host adaptor is fast enough.. (and reliable)
-Thanks

I think that GVP are using the same PCB for 33 and 50 MHz. > I heard a viscous rumor that many 50mhz versions use a > 33mhz 68030.. Can anyone confirm this? Nope, not true! > Because if that is true, I can upgrade to a 50mhz amiga > for the price of a 50mhz clock crystal.. You also need a few different PALs. > I did not get my system with an IDE hd because someone > told me his IDE drive only achieved 300k /sec and was not > reliable. Way too low! With a Quantum 40, you should see _at_least_ 700K/s (DOS-level). Make sure the AT drive supports mode-2 or faster transfer rates. Slower drives may indeed appear to be unreliable. The Maxtor LXT200AT is a very nice drive, for example. I have never seen a read/write error on mine and it is quite fast (much faster than the usual Quantums). Ralph
