Hi Ronnie,

As others have already pointed out to you, most of the numbers that
you've posted are manufacturer's parts numbers, and not Motorola type
numbers. (Unregisted Motorola devices type generally begin with the
letter "M" except for some diodes.)

Checking in my 1966 Motorola Semiconductor Device Manual, the MA900 is
a high-voltage switch that is usually employed for driving neon
readouts, relays etc. The family is Germanium, PNP. The MA900 is not
specifically listed, but two other later member's of the MA 900 family
are. IIRC, the deviced listed in the book are the MA909 and MA910,
which likely have improved parameters over the original MA900.
Essentially a 75Volt devices with a current capacity of up to 200-Ma
capable of 150-mw.

The 2N1192 is also listed (2N192-2N1194) as PNP germanium transistors
for high-gain audio amplifier and switching use.

The book contains data sheets on both the above devices, which I would
be happy to scan and email to you if you want them. Can't be of any
help on the other devices.

Just let me know. My email address is , not the
address shown on the post which is intentionally obsolete to discourage
spammers.
