After opening the ASR33 shipping container perform, the steps of the following procedure: When the light goes off, the computer stops. The serial to parallel converter receives the serial input data from the teletype keyboard or reader and sequentionally shifts it into an 8 bit register. E82 E2 thru E6. Most war diaries provide a day-to-day record of operational activities and sometimes administrative activities as well. Con- tact the carrier and Data General immediately if any damage is discovered, specifying the nature and extent of damage. The detailed technical descriptions presented in this manual assumes the user of this document has a thorough knowledge of the operation of TTju L logic circuitry and the fundamentals of digital computer operations.

At completion the data lights display the word deposited.
With typical operation of the program, a incrementing sequence from 1, g to approximately 3, g will be observed in the Address Register display. The input Data Multiplexor actually consists of two separate multiplexors, one driving the “X” input lines of the Adder, and the dt driving the “Y” input lines of the Adder.
Turn power “ON” by setting the key to the vertical gd. Oscilloscope may be used. This chapter contains a complete list of replaceable parts for the Supernova Com- puter.
Teflon Coated Slotted B. These procedures should be performed Figure The Supernova is a iivo purpose computer with, a 16 -bit word length. At completion the lights indicate the next state to be executed.
Load test program Binary as per paragraph Blank entries in level column denote flip-flop outputs which may be in either logic state.
For write, the drive current is applied in the opposite direction and thus tends to drive all the cores in the selected location to the 1 state. Each printed circuit board assembly is shown as a dash line enclosing the logic sections physically mounted on that particular board. Old and nonstandard browsers can put your security at risk, are slow and don’t work with newer features.
The fre- quency of die crystal used in die oscillator depends on die Baud rate selected by the customer 0 However, the frequency of Y2 can be calculated by multiplying X Baud Rate. If the block contains fewer than thirty -three words the processor simply reads the trailing blank tape as zeros.
All electrical drawings referenced in this text are compiled and bound into Section VII of this manual. Unpacking the ASR33 Teletype. Complete verification is obtained when all of the Supernova diagnostic program tapes included in the documentation package have been run successfully. The Examine switch output, EX, becomes true when the switch is actuated.
However, the Console Data switches remain operational to allow the operator to supply information to the program when requested by the program.
The X and Y windings and associated selection logic are shown on sheets 4 and 5 of Drawing ASR33 Teletype Height on stand: This program should still be intact within the memory and available for execution. The first paragraph describes the approved procedures for unpacking the Supernova.
Burlingame, California Table This list a I so may be referenced as a bridge between the logic configurations shown on the various CPU logic diagrams and the IC package pin definitions summarized in Cg A of this manual. The parts list for each major assembly lists the circuit reference designator for each part, along with the manufacturer’s part number and description.
Copies of diagnostic tapes as well as individual program documentation are part of the software package delivered with the Super- nova. Iivo value of this capacitor depends on the operating frequency ivlo This resistor is also brought out to allow external resistance cou- pling.
The specifications are listed in the five following categories: Connector P2 is the termination for an internal cable which con- nects the Regulator circuits on the Regulator Board assembly with the rest of the components of the power supply e.
Static tests are performed manually at the Operator’s Console. Remove keys from plastic bag, insert the key, turn com- pletely counterclockwise to the ” Off” position.
Individually the programs test various logic areas of the computer and
