[comp.sys.amiga.hardware] trouble with A3050

jmpor@dynam.UUCP (Jean-Marc PORCHET) (11/01/90)

I have just bought a A3050 (A3001 at 50 MHZ) but I have many problems
using it.

first problem : when the cpu is clocked at 50 MHZ and I made heavy use
of the 882, the machine crash with a GURU number 0x00000006,
(gomf say Illegal coprocessor  instruction), but when the cpu is runnig
at 28 MHZ all is ok. If I don't use the 882 all is ok at 50 MHZ.

second problem : when I'm trying to load the 2.0 (I'm commercial developer)
with mmukick or setcpu 1.6 the machine reboot under 1.3, again all is ok
at 28 MHZ. (have you an idea dave ???)

Is some one on the net that's have an idea of what's wrong ?
(before I send it back to GVP)

thank's in advance for any help ?

Sounds like a faulty '882 to me. Try changing it.

Give ZKick a try.
