You've looked in EK-MSV1Q-UG-002, right? That seems to cover a couple of
different revisions.

The M8067-L variants are all MSV11-PL (512-Kbyte QBUS MOS memory). The
last letter usually indicates the vendor of the MOS chips used.

I too couldn't find any documentatin for this; there is the 'SMS 1000
Microcomputer System OEM Manual', which says how to configure one for a base
configuration. I started to work out what the configuration switches do, by
experiment, but I got distracted before I finished. I have found my notes
from this exercise, and can send them to you if they are of any use.
