The Hp200lx Connectivity Pack allows full emulation of Hp200lx on J720
(and other hpcs like J680
) running under pocketdos!
The connectivity pack can be downloaded from here after free registration:
Vetusware
The pack contains 3 floppy images which can be mapped to drive A in turn and installed by running setup.exe from pocketdos. You can install to any mapped drive that pocketdos can see. I chose a subdir on my cf flash mapped as S:CPACK200
In addition to a DOS environment, CPack needs an INT5F Palmtop graphics emulator. One is already supplied with CPack, called CG.COM. It is automatically called from inside the app200.bat batch file that launches CPack. You may experiment with different Palmtop graphics emulators, to get different - maybe better - results
There's some good info about this here:
hermocom
To use pocketdos native displaydriver, entirely remove or comment out the CG.COM references from app200.bat in the CPack dir. The image above is using the native display. Note I had colour selected, but display is b/w for some reason unknown as yet.
The image below is using cg.com driver:
I found that pocketdos complained of an invalid display mode if set to EGA mode
(pocketdos settings/display/type
) when cg.com is enabled, so I set to VGA and all was well.
If anyone tries running this it would be great to get feedback on this thread about what works/doesn't.
Cheers
Steve
