|Emulators for old HP|
Message #1 Posted by Olivier De Smet on 8 Jan 2012, 7:55 a.m.
I enjoy writing emulators of old computers and calculators (see http://sites.google.com/site/olivier2smet2/)
After finishing an hp67/97 emulator for windows (with the roms from nonpareil), I started an HP15C emulator for windows
(with the roms of an old nonpareil release .. I use to archive files from internet for my own use ;) ).
Soon I started a new hp 67 emulator for android, followed by an HP33/34 one (same woodstock processor).
As it was nice to write this one for android I started a new HP11/12/15/16 one for android.
Actually it's near the end of the beta phase. (perhaps I will start an HP41 emulator before finishing this one ...)
But I have now a strange observation :
when running emulators (windows or android) from the HP1x roms from nonpareil, it display "running" with the "r"
in the lower part of the second digit, but my own original hp15c display "running" with the "r" in the upper part of the digit.
Did someone already notice this display artifact ?
Could it be due to roms version ?
P.S. all those 1X emulator are private (as it seems there are some trouble with the copyright of HP1x roms)
