Note: in all this document, HP41C or 41C means any of
the 41 series: HP-41C, HP-41CV or HP-41CX.
Emu41/DOS
(short Emu41) is a software
emulator of the HP41C machine and HP-IL system. Emu41 is a 16-bit DOS program and runs
well in a command box under various 32-bit Windows systems (98, 2000, XP, ...).
Emu41 can run on 64-bit OS using a virtual DOS environment (see below).
Main features:
- FREEWARE: free for non
commercial usage, (a short mail with your opinion to the author would be
appreciated),
- emulation of ROM
and XMEM modules, compatible with standard ROM image format (.rom, .41r),
- support for
advanced modules: Hepax, MLDL, W&W 64K RAMBOX II
(or HP-41CY), 128K Eramco RSU,
- emulation at
machine code level: can execute synthetic programs and micro-code,
- emulation of the HP-IL system and support of 8 internal
virtual HP-IL devices
(one video display, three mass storage units, one printer
port, one DOS interface, two serial COM ports),
- support of the PIL-Box,
- HP 95/100/200LX and HP Portable Plus versions,
- Full source code released.

Emu41 uses ROM images of HP41C ROM and modules (X-F,
Time, ...). You can find ROM images on the great Warren Furlow's
HP-41
Website
To help you, you will find here the necessary images of the HP-41CX machine, as well as the HP82143,
HP-IL, Advantage and X-I/O modules, ready for use with Emu41. If it happens
that the Hewlett-Packard company should be opposed to this, I would immediately
remove these files from my site. Don't ask me to provide other HP or third
party ROM images.
Emu41 now supports the PC serial COM ports, in order
to allow downloading program files from Emu41 to an external HP41 through the
HP82164 HPIL/RS232 interface. This document gives some basic information: setup
for PC / HP81264 link (pdf).
Running
Emu41/DOS on 64-bit Windows systems
Since most bare 64-bit Windows OS versions don't support 16-bit DOS
applications anymore, a virtual environment must be used.
DOSBox
version 0.74 has been successfully used to run Emu41/DOS on a Win8-64 bit
system.
Emu41/DOS
and the PIL-Box
Emu41/DOS includes a native support of the PIL-Box, which works
"reasonably" well on native DOS, Win98 or Win2K systems.
These systems are now obsolete and Emu41/DOS has to run in a virtual DOS
environment on modern 64-bit OS, making this native support no more effective.
I now recommend to use the ILPer software in
conjunction with the PIL-Box, as a gateway between Emu41/DOS and a real HP-41C
for program/data exchange.
This is done by sharing the same virtual drive HDRIVE1.DAT between Emu41/DOS
and ILPer:

side.
