Because of many requests for an HP42S emulator I decided to publish the alpha version sources of an program for Win32 that can emulate a HP42S and similar ones of this series. The sources base on Emu48 and are published without any support.
Because it's not finished product, I only publish the sources. You need the MSVC++ v6.0 compiler for compiling the sources and with additional work it will be possible to use the MinGW package for it.
Because of licence reasons ROM images aren't included, read J-F Garnier MoHPC article how to make make one. The emulator needs a one Nibble per Byte format also used by Emu48.
