Here's a printout of the BREAKOUT game included on the Museum's 00075-13007 Games II LIF file. The game requires an HP 82163A and compatible display or equivalent. The display emulation included with
pyilper connected via a
PIL-Box works fine. To prepare a unicode text listing for conversion to basic use the lifutils (that come with pyilper) like this:
Code:
textlif75 -n BREAKOUT <breakout.txt | lifput mylif.dat
Then, on the 75, type something like the following:
Code:
copy 'breakout:m1' to 'breakout'
transform 'breakout' into basic
One additional step is needed after transforming the file to basic. On lines 1110 and 1120, the variables N1 and N2 should be replaced with '⍺' ([shift][I/R][up arrow]) and 'β' ([shift][I/R][down arrow]) respectively. The given quotes should be preserved.
It's a lot easier to load this guy from LIF collection for the 75 (/HP%20Museum%20V8/data/cd27/sw/75swsftp.zip in the
museum documents collection) but this technique should work for any other 75 BASIC listing you might run across.
