Ferranti Pegasus 1 Computer
The Ferranti Pegasus mark 1 (first named the FPC I -Ferranti Package Computer) was first made in Great Britain in either 1955 or 1956. It was a valve operated main frame with a 48 register immediate access store using nickle delay lines. It had a magnetic drum store initially with a 4K word capacity later increased to 7K. Input and output was via a 5-hole paper tape.
The Pegasus 1 word length was 39 bits catering for 11 decimals.
Early Technology is offering the MONITOR PANEL and the PROGRAMMERS'CONTROL PANEL from the Control Unit of the Pegasus 1 computer, along with the DRUM STORE CONTROL UNIT and the PEGASUS PROGRAMMING MANUAL (hard cloth bound 1962 for Pegasus 2. 319 pages)
These parts came from the firm of Parsons Peebles of Edinburgh which made heavy duty transformers and other electrical equipment.
All three hardware parts have their original Ferranti inspection lables attached. The Monitor unit is dated 20 Dec. 1959. The Programmers'Control Unit is dated 20 Aug 1959. The Drum Storage Control Unit is dated 9 April 196 (Presumably 1960).
Monitor 19" wide x 14" high x 36" depth (48 x 36 x 92 cm)
Programmers' Panel 22" wide x 5.5" high (56 x 14 cm)
Magnetic Drum Panel 26.5" wide x 5.5" high (67 x 14 cm)
All three pieces of this historic hardware appear to be in excellent original condition and should be able to be restored to working order if required.
