Title: Microbotics 8UP! with simms
Post by: mechy on June 08, 2015, 03:23:36 AM

Hi,
  I finally dug out the old microbotics 8UP! card (version with the simms) and i cant seem to find the jumper settings anywhere on the net(amiga resource doc is for the older one).
Playing with the jumpers,i managed to get 4MB to show up, i just need it to see the other 4MB.
Does anyone have the jumper settings for this board???

thanks,
 Mech
