- Three days ago, I tried an ATonce emulator card
- on my A2000 and troubles begun. The ATonce which is one of the
- old versions and for the A500 but I think, it may work with A2000.
- (please, I'm not an idiot, I'm only crazy)
-
- I pulled out the 68000 and placed ATonce card then replaced Gary on
- his special socket. This socket is very simple, only there is
- a 1K resistors between pin 1 and pin 35. (The manual describes as;
- if there is a different bus master than the 68000 which takes over
- the system-bus, then Gary generates the DTACK signal with a little
- delay. This shortcut is for disable this delay.)
-
- When I turned on the machine, it froze after 30-40 sec. works.
- I reset it and tried 3 times more but the result didn't change.
- I decided that it will not work with this model ATonce then
- I pulled out it and replace 68000 and Gary without socket.
-
- But when I turned on the machine, it didn't boot. The screen
- turned dark-gray to light-gray and waited some more then turned
- dark-gray again.
-
- I think my Gary burned-out. I bought a new Gary chip and
- replaced. When I turned on the machine it worked!
- I tested something like opening drawers and loading some applications
- but only 3-4 minute after machine froze again.
- I turned off and on but same symphtom appears, new Gary burned-out.
-
- Now, I could not buy another Gary until this problem is fixed.
-
- Please help!

-
- PS. The A2000 is rev. 6
- It has 1.3 ROM and 1MB chip and 2MB fast RAM.
- GVP series II and Maxtor HD. installed.
-
- PS2. Here (Izmir/Turkey) there is an authorized CBM service
- but the technician understands about Amiga h/w not more than me!!!
- (Once my old A500 had a trouble and when I went to them, they
- doubled it!)
