Subject:      for the numbers lovers my A4000 speed results

  Well all you numbers lovers here they are my sysinfo 3.01 results of my
  yes mine all mine Amiga 4000. I finally got it, I paid 4250 german marks
  that is about 2692 US dollars and i find that very cheap for such a super-
  duper machine.

  So all you doom thinkers and Amiga 4000 lovers here are the numbers, enjoy:

 They only thing you can't find in this list is the HD speed, strangly that
 isn't printed to the file, but the speed is 1.065.345 bytes/second so that's
 a cool Megabyte a second. (that is about 3 times the speed i was used to on
 my amiga 2000 with 47 mb supra drive.

 The Amiga 4000 is a FAST machine that does exactly do what i want it to do
 Of all the demo's i have tested until now about 80% worked after switching
 the AA and 68040 caches off (with the magnificent help of boot menu, reset the
 amiga and just hold down your mouse buttons and see for your self).


 But stiil some questions remain: I have tried to format a HD floppy.
 that is 1.76 mb on amiga dos and 1.44 on msdos but until today it has never
 worked. while formatting a cannot format cylinder X messages turns up.
 this x is everytime different never the same even on the same floppy.
 eg. first it was on cyl 54 then 62 then 74 and i thought he we are doing fine
 here but then it was on 5 and i gave up. they are 3m hd floppies and work
 fine on msdos machines. i have also tried to read something of a msdos 1.44
 floppy and got a crc error writing is also not possible.

 so I get the feeling that the whole HD floppy stuff on a Amiga 4000 is still
 very buggy, or they have put a low density floppy drive in the machine.
 Is there a way of finding out without opening the case (warrenty you know).

 No No doom thinkers 880 amigados both OFS and FFS and DCFFS work fine also
 720 msdos is no problem at all they all work fine.

 Another strange thing is the total absence of the narrator and the say command
 is this not possible on a a4000 or has commodore forgotten to put it on the
 workbench 3.0 floppies (6 of them).


 But for the rest:

  Yes I am a happy man a very very happy man he he he.........
