5000/25



G'day,

My first foray back into PMAX in more than ten years. I've managed to get a 
5000/25 with 24mb RAM (8 simm+8 simm +8 onboard ), the obligatory KN02 R3k up 
and running. 

System came with Ultrix 4.4, boots happily after a thorough clean and cap 
replacement in the PSU. 

Whinges about the battery (seems to be missing or if it's part of the RTC it's 
flat). I can deal with it later.

Complains with 6.1.3 along the lines of (please excuse me re-typing this off 
the vt220, I hope I didn't make any errors..):

I've had similar issues with 1.6.2 and 2.1. 

Ideas? Constructive abuse?

Thanks.

Al.
