Most modern microprocessor-based instruments contain EPROM's. ROM, EPROM, or EEPROM storage usually contains text (CPU instructions) and data (binary and text strings). Displaying the contents of the EEPROM often gives insight into the internals of the operating system or programs running on the CPU. If nothing else one can see the origin and context of all the messages that are externally displayed by the instrument.
With modern instruments it is also quite common to see remnants of revision control (RCS headers) and debug statements (casual printf format strings) left in the compiled image. This is true for operating system kernels, application programs of all sizes, and embedded programming. Although these don't have any effect on the released product, they do sometimes give appreciation and insight into the architecture and orderly design of the instrument
While most of the 512 KB EEPROM contains garbage-looking binary instructions and data, ASCII strings do stand out from the noise. A quick look at strings in the EEPROM show a large and complex embedded program. For example:
Low-level CPU support:
: PC = %#8x, SR = %#04x , address = %#8x RESET to recover. bus error address error illegal instruction divide by zero
Evidence of a real-time operating system:

Interfaces with the time interval counter FPGA and interpolator:
setup fpga ERROR: FPGA done line went high early ERROR: FPGA programming failed FPGA programmed Result uncomputable Measurement aborted Interpolator calibration failure
Exhaustive lists of errors:
No error Command error Invalid character Syntax error Invalid separator Data type error GET not allowed Parameter not allowed Missing parameter Command header error Header separator error Program mnemonic too long
Humorous debug comments:
Oooh! That tickles. I don't know that vector.
Raw strings for the famous SYST:STAT? message:

Complete lists of instrument status:
No holdover cause Holdover due to hardware failure Holdover due to manual Holdover due to GPS Holdover due to TI error Holdover due to TI limit exceeded Holdover due to temporary mode Holdover due to 1PPS selection
Long lists of SCPI command fragments:
CALC ULATE ACC UMULATED LEAP SECOND IMM EDIATE SYNC HRONIZATION
And many more interesting strings. Those of you who are programmers will immediately recognize tables of error strings, production and debug printf format strings, interrupt vectors, SCPI parsing tables, and the like.
Someday, long after the copyrights have expired, someone might want to donate the Z3801A source code to the museum so this piece of history isn't lost forever. The same goes for the PIC sources.
A check shows no long list of new SCPI commands; thus the documentation for the Z3801A and related GPS receivers (e.g., 58503A, 59551A) appears complete. Recall that most SCPI words can be given as either a 4-character abbreviation or the full spelling. Here's a dump of all SCPI commands in a slightly different format:
