[time-nuts] Z38XX PFORTH interpreter question

[Mark C. Stephens]

You might find there are either hard links on the board or different firmware?

Subject: [time-nuts] Z38XX PFORTH interpreter question

Hi,
Has anyone made further progress in understanding the PFORTH commands?

I find with my Z3815A (with an E1938A hockey puck oscillator installed) that the command 'puck' returns:

a= -6.305066e-13 b= 0.000000e00 a/d = 1.600000e+01 puck communication is alive puck warm= 1 puck EFC ADC err= 0
status1 byte= 1
status2 byte= 0

What fun! I wonder what the three variables are and can one change them?

As a separate but related question, I've just swapped out a failed MTI 260 OCXO from this Z3815A and fitted in its place the older E1938A hockey puck. The problem I have is that the EFC sense seems to be reversed. Does anyone know how to change this, either by sending a PFORTH command or otherwise? It would be great to get the Z3815A going again.

73,
Murray ZL1BPU
