as most of you know, in 1990 the 9V motor 8720 was released, it followed the
well known 4.5V motor 870 / 8700.
At that time, all Technic instructions had a section that showed how to motorize
it. Either the A-model or the B-model (exception * see below).
Due to the change from 8700 to 8720, the instruction were upgraded.
Until now, I found both both 4.5V and 9V motorizing instruction variants for
the following sets:
8024, 8034, 8044 Universal Sets
8835 Forklift
8854 Power Crane
8862 Backhoe Grader
8865 Test Car
The following sets also were still listed in the 1990 catalog.
But I could not yet find versions that show motorizing with the newer 9V motor
8720:
Does anyone have an instruction book (or at least pictures / scans) for one of
these 5 sets, that show the 9V motor as an upgrade option?
I already searched the usual online resources, but it seems that they have all
copied the scans from each other, so you find the same scans everywhere...
(*) no rule without exception. For the pneumatic Forklift 8843, there are two
different version of the instructions.
The first version shows a motorized "C"-model, while the second version
dropped the C-model and shows only A- und B-models.
