VAXstation 3100 FB problem

[Tore Sinding Bekkedal]

Hello, I've got a VAXstation 3100 (Thanks, Peter Coghlan!) that I
recently acquired while on holiday in Ireland. There is a problem I'm
having with it - the 8-plane colour display controller is giving me an
error message on startup:

??  4  00D0  0016.0052

When I run test 4 on the Chevron prompt I get:

>>> test 4

4?..
 84 FAIL

and when I try test 50 I get

(...)
?? 8PLN       0016.0052
(...)

Does anyone know what could be ailing my new toy? The machine will run
perfectly using the mono adapter, though VMS 7.3 will crash hard when
trying to access the device (starting the X server).

Is there a list of these error messages, somewhere?

Thanks,
Tore
