Thomas part numbers

[James Dunn]

Hi all,

	Could anyone enlighten me on some Thomas chips from the Troubadour
Organ? They use their own part numbers:

13-5045-6; LSI 101 Keyer, 
13-5027-6; LSI Rhythm counter, and 
13-5032-6; LSI Features.

I have tried numerous searches, someone mentioned on this list (I
think), that the parts were originally SSM parts with the Thomas number
stamped on top. Is this true? Are Thomas still going, I can't seem to
find them anywhere. Any information appreciated.
Thanks,

James.
