A 26K Library for the HP48 SX/GX
+ A through F keys moved down to row 4 keys so they are closer to the numeric pad.+ HP48 MODES, PRG OBJ and PRG STK menus remain accessible at all times.
+ HP48 B->R and R->B as well as HP16C FLOAT and FIXED functions provided.+ Converts to/from IEEE 32-bit floating-point format.
+ All library functions available for user programs.Some Info:
The HP16C Emulator Library has been available now for the HP48SX since early 1993 and appeared in the EduCalc catalogs #59 through #64.(EduCalc went out of business shortly after publishing their catalog #74.)
Following the introduction of the HP48GX, a new version of the library was devised which is compatible with both the SX and GX units. This version works in all ports of the GX. The library encompasses all the functionality in the HP48's native MTH BASE menu plus all the functionality of the HP16C calculator (discontinued around 1987) and more, running in the HP48 RPL environment. The math functions supported are:
Arithmetic: +, -, *, /, RMD (remainder), NEG, ABS
Double-word: DBL*, DBL/, DBLR (double remainder)
Bit Shift/Rotate: SL, SLn, SR, SRn, RL, RLn, RR, RRn, LJ (left justify), ASR, RLC (rotate left thru carry), RLCn, RRC, RRCn
Masking: MSKL (mask left), MSKR
Bit Set/Clr/Test: SB, CB, B?, #B (no. of bits set)
Logical: AND, OR, XOR, NOT
Conversion: ->IEEE, IEEE-> (IEEE standard 32-bit format), FLOAT, FIXED, R->B, B->R
Relational Tests: ==, <> (not equal), <, <=, >=, >
Carry, Range: SETC, CLRC, TC (toggle carry), CRRY?, SETR, CLRR, TR, RNG?, CCR (clear carry & range) Complement: UNSGN (unsigned mode), ONES (ones complement), TWOS (twos complement), CMP? (what is current mode)
Word Size: STWS, RCWS
Math: Square Root, Square, Y^X
Display: #0000... (Leading zero's mode), MLSHOW (Display full number in multi-line format), SHOW BIN, SHOW OCT, SHOW DEC, SHOW HEX (displays in specified base briefly)
An overview of the library:
The entire HP48 keyboard is redefined and labeled using the supplied four-color mylar keyboard overlay. No function is more than two keystrokes away.
LCD shows all modes (current base, word size, complement mode, plus status of carry and range flags) at all times in the status area.
Entry of binary numbers does NOT require the use of the #-sign delimiter; it is added automatically.
Both signed (ones and twos complement) and unsigned numbers are supported with all math functions.
Keys A through F have been moved down to keyboard row 4 so they are closer to the numeric keypad.
Illegal numbers are disabled when applicable (i.e., in BINARY base, keys 2 through F are disabled)
Entry of both integers and reals are permitted without delimiters. Math on reals still available while library is active.
Negative decimal integers are displayed such as "#-5d" using a custom display routine.
All emulator library status is preserved when exited and reentered.
All emulator functions may be used in user program objects.
I finally ran out of printed user manuals after ten years, and now offer all the documentation (as well as the software) on a CD-R disk. The package includes library file for downloading to the calculator, 130-page user manual and mylar keyboard overlay. Also included on the CD is a 19-page user-manual addendum plus some additional printed materials. The cost is 25ドル.00, which includes shipping . (Sorry - I can't handle credit cards, but my bank will handle wire transfers - they charge me 10ドル.00)
