This SCADC mug was made by the wife of the USAF lead engineer and it is signed by the USAF and USN team members from the early years of the development contract. Alan Briggs donated this item and recalls that only about 12 to 15 were given to our team.
The names are:
Robert (Bob) Gemin USAF Lead Engineer Wright Patterson (his wife made the mugs) He was a great fan of the 'Hitchhikers Guide to the Galaxy' and the only one who understood why a Processor fault produced fault code 42!
James (Jim) Whelchel USN Lead Engineer Patuxent River. He once berated us at a Progress meeting telling us what faults we had failed to resolve. Only when we queried his detail did he realise he had picked up his logbook (spiral bound) upside down and given us our competitors development issues by mistake!
Jerome (Jerry) Shuchart USAF Logistics Oklahoma City. became program manager later as it moved from production into support phases.
Leonard (lenny) Seeker USAF Contracts Wright Patt
Lowell Thomas USN program manager, USN, Crystal City, Washington (ex Test Pilot, very knowledgeable)
John Hix, program management specialist, wright Patt
James (Jim) Young, Support specialist USAF McClellan (i think)
John Lapp USAF Program manager
Steve Kalatucka Interface Specialist, USN Indianapolis (I Think)
Donald (Don) Wilson, Logistician, USAF Oklahoma City
Bill Pitcher, Flight Test Support, Pax River.
Roger Logan, Contract manager, USAF Wright Patt.

In 1981 Instrument Systems Division began the design of a new generation of Air Data Computers designed for the combined USAF and USN Standard Central Air Data Computer (SCADC) programme. The system was designed to fulfil the retrofit requirements of 38 different aircraft types and to do so with only four configurations. The aircraft types include the following:-

A-4M and TA-4J Skyhawk, A-6E/F, KA-6D and EA-6A Intruder, EA-6B Prowler, TC-4C Gulfstream, A-7D/E/K and TA-7C Corsair II, C-2A Greyhound, E-2C Hawkeye, KC-135 Stratotanker, C-5A/B Galaxy, C-141A/B Starlifter, F-111A/E/D/F, FB-111A, EF-111A, F-4C/D/E/G/J/N/S, and RF-4B/C Phantom and the S-3A/B and US-3A Viking. In 1992 an order for a further 290 units was received, being the eighth option, bringing the total procured to 5552 units. 387 units of the SCADC system were at this time being supplied for the F-14 Tomcat.

The high commonality was achieved with a unique software re-configurable design. Output parameters, ranges and scalings are selected for each aircraft type by the software, which recognises the host from a code wired into the aircraft connector pins. The SCADC core hardware set provides over 80% of the hardware in every application and the remainder is addressed by one or two special-to-type modules. A multiplicity of analogue interfaces can be handled and the Mil-Std 1553 DataBus is also a feature. Production commenced in 1985 with first deliveries the following year and in 1989 these deliveries surpassed 4,000 units. In addition in 1988 ISD received the Queen’s Award for Technological Achievement for SCADC.
