                         The Wom Tester

(Ed. 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.
