G1 Wire Matrix Printer Head & Printer Ribbon (DEC) A1 Gio For History of Printing
G1.1 Picture of Wire Matrix Printer A1 TCM? Put behind G1 for context
G2, F0#1 Commodore Calculator A2 Gio Early device using Intel4004? Integrated circuit chip. Compare with Marchant (G3)
G3, F1#6Forsythe's Marchant electrical calculator (right) F1#6, B2 Marchant Calculators, Oakland CA 510 839-0506
This Calculator was used by Professor George Forsythe at Stanford.
It provides addition, subtraction, multiplication and division, all performed mechanically. Results show on the carriage, as does one of the factors used in multiplication, or the divisor. This machine performed essential the cranking operation of earlier calculators, such as the Monroe machine, with single button pushes.
G3.1 Monroe mechanical calculator (left), ca 1930. F1#6, B2 Gio Inventor: Frank Stephen Baldwin 1839-1925. The Monroe company was founded in 1912 (near G3 for explanation [CMA]. This 10-key calculator provides accurate manual computation.
Each complete forward turn of the large crank on the right will add the value set into the 8 x 10 keys into the bottom register of the carriage. The top register counts the turns. Subtraction is achieved by turning the crank in reverse. To multiply the Repeat button is pressed and the crank turned as often as needed for the low-order digit. Then the carriage is moved to the right with the handle in front, so the next digit of the factor can be cranked in, etc.. The crank on the carriage is for resetting result and counter registers. Division is performed by subtracting the divisor left to right.
G3.3, F2.5 Table of Integrals and functions. B2 Gio Publisher: Chemical Rubber Company. Used by Gio 1956-1958 (near G3 for explanation .
G3.4 Friden mechanical automatic calculator (center), ca.1960. Side panels removed. F1#6 B2 Robert Floyd Automated multi-digit factor multiplication. Advanced models also performed square roots. The end of the line for mechanical calulation.
G4 Burroughs Compilogram (4-5 copies) B4 Gio Board game used to teach how a compiler works, to help students understand the Algol compiler for the B5500.
F2#2 Stanford AI Modem (a new Rs232 connector should be attached) A3 Gio To increase performance over the then typical 600 baud duplex technology, the Stanford AI-lab developed an asymmetric modem, which sent data from a terminal at 150 baud, but could receive at 1200 baud.
G6 TTL Counter B1 Gio For history of computation
G7.1 Relay Flip-Flop with instruction manual (copy 1) B1 Gio For history of computation
G7.2 Relay Flip-Flop (copy 2) B1 Gio For history of computation

G9 Slide Rule A2 Gio For history of computation: A slide rule has graduations on logarithmic scales, so that catenation of two factors gives the product. Illustrate in display with values, as 2.2 x pi.
G10 ACME Light Box F1#5 Gio Indicator for users of an early timesharing system using printing terminals. The ACME IS ON light is set periodically by the processor, and dims if no signal is received. The YOU ARE ON receives on/off signals for every allocated time-slice. The WAITING-FOR-YOU indicates that the processor is not allocating resources until it receives a typed response. The SPECIAL RUN indicates that real-time data-acquisition is in progress and is receiving priority.

G16 Strips from a 2361? Strip File A4 Gio capacity of one strip cccc
G16.1diagram to illustrate function A4 Gio DBD The strips are extracted from a cartridge, wound around a drum, and then read. About mm milliseconds are required to load a strip. Positioning the cartridge takes up to ss seconds.
G16.2Picture of 2361? from manual . A4 (get) Picture to put behind it. The xxx UNIT held 10 cartridges, each with yyy strips, giving a total capacity of 400 Mbytes.
F3#1, G17 Hollerith or IBM card A4 TCM A standard IBM card held 80-columns. Not more than 4 holes were punched per column, to keep the cards strong enough for mechanical processing.. An encoding (BCD) for 64 characters was common.
F3#1, G17.1 Dollar bill from <1920> A4 Gio The dimension of the Hollerith card was made identical to that of the dollar bill of those days, so it might be carried in a standard wallet.
G17.2Cards from IBM Selective Dissemination of Information (SDI) Retrieval System A4 Gio The SDI system selected cards denoting new articles from the library according to interest profiles of recipients, which were then mailed to the participant. They could be returned for ordering copies of the articles.
G17.3IBM Electric Keypunch F2#1, A4 IBM Research The Electric Keypunch (1923) increased the productivity of people entering data onto IBM cards.
G18 UNIVAC 90-column card C1 Gio Sperry-Rand, later Univac and now Unisys allowed all holes to be used, so that this card could hold two x 45 columns of data.
G19 DEC RL02 single platter cartridge (cut open to show innards) F3#2 Gio This singleDECRL02 platter cartridge has a capacity of 2.2? Mbytes. The reading heads were in the drive and entered the unit through the small port in the rear. Larger units were composed of multiple, up to 11, platters.
