Ive several troubles with my V1200. Can anyone pointme in the right direction?
Here is the related information:

Configuration: Amiga 1200 motherboard version: 2B
PSU: lab psu @5.00V, 10A (ripple free).
Core: r7389x12
OS: Coffing r55

Problems:

1) In specific and reproducible situations relative to the mouse pointer (By doing several clicks in specific areas of windows, it may be related to SAGA drivers), it stops working completely. A warm reboot fixes it.

2) Incompatibilities with WHDLOAD (Tested TurtleMode ON / OFF, ICACHE ON / OFF, SUPERSCALAR ON / OFF) salves that work correctly with WINUAE or AGA with 68040 accelerator or vampire V500 do not work on v1200. Example (I have several more): Spaceballs State of the art.Mainly timing issues, graphical/sound glitches.Working OK, without vampire installed and WB 3.1.

3) Unrecoverable random hangs, black screen or vampire logo after trying warm reboot. Only solution: full power cycle.

Thanks,


Morten Andersen

This may help u whit the timing issue

The other thing sounds like a bad connection as heat has something to do whit it.

Maybe the timing fix is ​​necessary, maybe not or it could be counterproductive.
If any user of v1200 can tell me if the demo "State of the art" works correctly with the WHDLOAD slave provided in the coffinos, could he point me in the direction in search of the problem.

Anyone?
