Reprinted from ELECTRONIC DESIGN #21, Oct. 11, 1977. TC) We regret the delay in our publication of the April 1 announcement of the new Tektronix WOM tester. The system is intended for use with the Signuteks 9046 X N random-access write-only memory or equivalents. The system is unique in its testing new devices (which enhance or deplete regardless of gate polarity). The tester provides fast, clean pulses by use of Pushme- Pullyou Drivers. Quadra-state comparators allow flexibility in checking WOM outputs with only 12 clock phases. The system uses TEKTEST IXX, Version 999.99, which is neither upward or downward compatible with other test languages due to its unique language structure. Users can be freed of problems with hexadecimal, octal and other cumbersome languages, and revel in the simplicity of ones and zeroes. No compilers assemblers or translators are needed, so there is ample space for test programs. The address ports of the WOM are multiplexed with a negative frequency to achieve optimum resolution. The drain on the WOM is tested by monitoring a 5-gallon bucket. Handlers are easily interfaced to this tester with only 500 signal lines. The system is capable of binning into two categories: one for NO-GO DIPs, the other for FAILED I2R. If the I2R mode occurs, it's time to call the power-distribution agency to find out how many substations went "WOM" as they exceeded maximum dissipation. The instruction set includes: BH Branch and Hang IIB Ignore Inquiry and Branch TDB Transfer and Drop Bits DO Divide and Overflow SRZ Subtract and Reset to Zero PI Punch Invalid SSJ Select Stacker and Jump FSRA Forms Skip and Run Away RASC Read And Shred Card SRSD Seek Record and Scar Disc BST Backspace and Stretch Tape RIRG Read Inter-Record Gap UER Update and Erase Record SPSW Scramble Program Status Word EIOC Execute Invalid Op Code EROS Erase Read-Only Storage PBC Print and Break Chain CM Circulate Memory MLR Move and Lose Record CRN Convert to Roman Numerals DMPK Destroy Memory Protect Key DC Divide and Conquer EPI Execute Programmer Immediate LCC Load and Clear Core HCF Halt and Catch Fire IDC Initiate Destruct Command Depending on configuration, this machine will sell competitively from $1.98 to something less than the national debt.
