This is a small tool for checking the ROM checksum of the early Clamshell
series calculator images running on the 1LK7 Saturn and 1LP2 Centipede chips.
These ROM images have build in checksums to test the integrity of the ROM
content. Because the ROM upload process over the IR-Port is quite difficult,
you can't be sure having no data transmitting errors.

This program accepts packed or unpacked binary images of 64 and 128 KB ROM
size.

Examples for

1) 64KB ROM images

- HP18C

2) 128KB ROM images

- HP28C


To check a ROM image, start a Command Prompt while running Windows, and type:
	Champchk <ROM-File>

where <ROM-File> is the ROM image you want to test. As result you will get a
report of the checksum check.
