Crashing A1200

[amigakit]

Check the RAM on the accelerator by completely filling the RAM disk with data and then purging it (delete all the data)- if it crashes -could be faulty memory.

Could be the connection between the accelerator and expansion connector on the motherboard- try removing the accelerator and testing the Amiga with some software - does it crash then?   Also caerfully clean the expansion connector.

Also check the accelerator for any corrosion (leaking batteries etc).  Check any SIMMs are securely in their slots.

Check the motherboard is lying straight on the plastic base of the A1200 - there are grooves for it to rest in.  A slightly bent motherboard can cause problems.

Always check the A1200 for stability problems with a Workbench floppy disk rather than booting from HD.

Perform the RAM disk test (complete fill/purge) when booted from Workbench disk to check Chip RAM.

Ensure the Kickstart chips are inserted properly into their sockets and no pins are bent.

BTW: If you want us to check the motherboard, that isn't a problem.

Hope you get to the bottom of this.
