HP Users' clubs' Swap Disks

These are copies of the collection of HP users' clubs' Swap Disks, which originated as CHHU Swap Disks. Please send any comments, suggestions &c to Tapani Tarvainen <tapani@iki.fi>.

The directory names reflect the original volume labels, and file names are as originally except that they've been converted to lower case, an extension indicating the file type has been added (see table below) and a few HP-41 files with special characters in them have been renamed (see list below).

In addition HP-71 BASIC programs have been saved both in original, tokenized form (*.b71) and as text (*.t71), in order to allow viewing them before downloading to HP71 and possibly for use in other machines like the HP-75 (a few files couldn't be transformed, however). If any HP-75 owner would like to volunteer to do the same for HP-75 BASIC files, please let me know! (HP-41 programs could also be saved in ASCII form (listings) -- if there's enough interest I could do that. Let me know if you'd like that.)

Filename extensions:

`txt`	HP-41 ASCII = HP-71 TEXT = HP-75 LIF1
	(Note: these have been converted into MS-DOS text files with cr-lf-terminated lines. Some LIF1 files might be corrupted in this process (especially if they contain graphics data). If you find any such here, please notify tapani@iki.fi. Thank you.)
