Chip 48 version 2.25 - the version of Chip48 from which Superchip was originally spawned.
This email contains the ASC format for the Chip48 binary for the calculator.

I transmitted this to an HP48 and used the ASC-> program to generate the c48 binary included in this repo.

Here is CHIP48 version 2.25.  It is mostly the same as version 2.20,
except that it is supposed to fix the dreaded "display offset bug".
There is one other small difference: the 2.25 Code object is no longer
self-modifying, so you can put this in ROM if you like :-).  However,
that also means that it will no longer remember the previous state of
the sound on/off flag like 2.20 did.  

The CHIP48 version 2.20 release posting (which includes the
documentation and the BRIX game) is available by anonymous FTP from
vega.hut.fi, directory /pub/misc/hp48sx/asap.  This article and the
source for version 2.20 are also there.

The source and uuencoded binary for version 2.25 will also be made
available for FTP and maybe posted to c.s.h.  Unfortunately they will
be delayed by a week or two because one of the two 40 MB hard disks in
my home machine just broke down, so the machine won't boot although
the source is still safe on the other disk (anybody want to sell or
donate a hard disk? :-()

Decode this using Bill Wickes' ASC-> program and save it as CHIP.  The
checksum should be #9D0Eh and the length as calculated using
"blue-arrow CHIP BYTES" should be 1738 bytes (slightly shorter that
version 2.20).
