Thanks to both of you for the information. I had looked at hpcalc.org, but did not realize that prgrams written for the other calcs would work with the 50G. Is this typical of 48/49 programs?
First, some definitions. By "48 series", I mean the 48SX, 48S,
48GX, 48G, and 48G+. By "49 series", I mean the 49G, 49g+, 48gII,
For the 49G, the "ROM" revision should be at least 1.19-6, but
preferably 2.09 or 2.10-7. Of course the 49g+ and 50g should use
2.09 or 2.10-7. With the 48gII, the ROM really is Read-Only
Memory, so you're stuck with whatever the unit was manufactured
For pure UserRPL programs, a Kermit "ASCII" (source code) transfer
from a 48 series to a 49 series will usually work, although a few
48 series commands may behave differently in the 49 series. Note
that for any SYSEVAL or LIBEVAL command, the entry point will
probably have to be changed.
In general, binary transfers between the 48 and 49 series won't
work. However, for a pure UserRPL 48 series program, you can use a
binary transfer to a 48 series calculator or a 48 series emulator,
and then a Kermit ASCII transfer from there.
To use a 48 series SysRPL program in a 49 series, if you have the
source code, then it should be possible to port it to the 49
Any 49 series UserRPL program will work in any 49 series
For 49 series SysRPL programs, if only supported entry points are
used, then they'll work in any 49 series calculator. If
unsupported entry points are used, they may crash with any other
Anything for the ARM-based models (49g+, 48gII, and 50g) that uses
the underlying ARM processor or uses the added "Saturnator"
assembly language instructions, instead of sticking to RPL or
legacy hardware Saturn instructions, won't work in the 49G or the
