There still is a tech guy around Aachen called Michael Kemper (Miketech). Don't know he was the manufacturer.
AFAIK it's the same Michael Kemper.
Back then he also did the upgrades of HP 48G/+/X calcs for Dynatech.
I once bought a new HP 48G+ with RAM expanded to 1280k from Dynatech,
which actually was done by Michael Kemper.
