[Info-vax] Old MicroVAX Crash

[Christoph Gartmann]

Hello,

during Sundy night our old MicroVAX3100 crashed:

        CPU 00 -- MACHINECHK, Machine check while in kernel mode

A look in ERRLOG.SYS reveals:

 ******************************* ENTRY       3. *******************************

Any ideas on what could be broken here?
