I used to have a Cloud 999 local to me that had a flat battery, so every morning left mixed 999 on the line... Thank you very much
I remember plugging a 5p £3 version that never streaked, it didn't respond well after a ram reset either. I noticed in later revisions especially Nudge Nudge Wink Wink, the early version plug would come back with it having to reach it's target percentage from scratch like normal, later revisions started off more balanced percentage wise after a ram reset.
You can ram clear some other MPU4 based machines if you can reset the machine at the crucial time. Sunset Boulevard can be ram reset from the Blue Sevens, timing is critical. I did manage to ram clear a Road Hog once, totally by mistake. I was on the feature board and I plugged the machine when it came back it had ram clear reels, still have no idea what I plugged it on.
