Hi,

Anybody have a library of transistor databooks
from the early 60's? I'm trying to find technical
info on the following devices:

Power Transistors:
Motorola 48S23 in TO3 Steel case

Signal Transistors:

Motorola 48S45 (624 date code or other marking)
Motorola MA900 (Sort of crossed to NTE 102A or ECG 102)
Mototola SM1824 (612 date code or other marking)
(one schematic I have shows this to be a
PNP type)

2N1192 (Schematic shows as PNP type - one hit shows as
Germanium)
Motorola SM2140 (Schematic shows as PNP type)
GA987 (980425 date code or other marking)

I'm unsure about the manufacturer of the last device. All the other have
the Motorola circle M logo clearly marked, but it is not on that device.
The system these devices are in was manufactured in the fall of 1963
so it is likely that the deisgn is from the 1960 to 1962. I'd like to
browse
through a 1960 to 1963 Motorola data book. I'm suspecting all of these
to be PNP type Germanium devices, but that is just a guess.

Any help appreciated.
