I think very much the same. There are chips with different T7xxx numbers
but the same long part number at bottom.

I wonder if T7543 etc. is the date code and that 23599809 or similar number is a

That's new to me..mean that with the reverse labeling.
That they may be programed was my supposition, that's why I've talked
about persons who kow about the numbers. Ok, ppl. that have a Burroughs
at home and know what that chips are doing may be scarce... ..after a closer look, the proms are don't
even Harris..that's something
lieke a "-B" on them..

Those look pre-programmed to me, the stamped label is often crooked and
all are backwards from how everyone else stamps their chips.
