IBM 7090/94 NASA Gemini Space flight Prototype computer board dates 1959, 1960. The 1250141 Board I was told from the person I bought this from at a Ham Radio Show that this was from the NASA Gemini space flight computer era and was a hand built one of a kind prototype for a Gemini computer system, not sure if was for ground or flight.  The board uses Teflon wiring on bottom, has 3 transistors all NPN and all Silicon that's rare for 1960, has 2 of a 2N338 both dated 1959 - 50th week,  the other is a 2N699 dated 1960 - 29th week, no manufacture on the transistors I can see. The 6 leg Sprauge cap is dated 1960 - 47th week. The resistor look like thin film type. There is also 2 QC stamps and one you can also see 4 letters. The last 2 photo's are for reference from Wikipedia, the second to last photo is the Mercury NASA Dual IBM 7090, and the last photo shows the IBM 7090 card plug in unit.  

The IBM 7094 is the same as a 7090 except the 7094 it had 7 index registers instead of 3 in the 7090, the IBM 7090 used some 50,000 Germanium transistors. WOW More info on the IBM 7090 at Wikipedia and other IBM sites.  I tried my best to find as much information on the IBM series 7090 systems, I hope this helps. If you find something please let me know, thanks!

Notable applications

Dual 7090s at NASA during Project Mercury.

    The Compatible Time-Sharing System (CTSS), the first general purpose time-sharing operating system,[14] developed at MIT's Computation Center on three successive computers, an IBM 709, 7090 and 7094 with RPQs for additional features. It eventually ran on two separate 7094s, one of them at Project MAC.[15][16][17]

    

NASA used 7090s, and, later, 7094s to control the Mercury and Gemini space flights. Goddard Space Flight Center operated three 7094s. During the early Apollo Program, a 7094 was kept operational to run flight planning software that had not yet been ported to mission control's newer System/360 computers.[citation needed]

    

Caltech/NASA Jet Propulsion Laboratory had three 7094s in the Space Flight Operations Facility (SFOF, building 230), fed via tape using several 1401s, and two 7094/7044 direct-coupled systems (in buildings 125 and 156). [under discussion]
