Sparcom General Chemistry Application Pac

[acapde]

This is what I did with the Celestial Navigation Pac that was a ROM image, I wrote a simple BASIC program that modifies the original file, it separates each byte in two nibbles (of course, you can use whatever language you feel comfortable with)

Code:


REM This is a QB64 routine that changes HP48 dump format, from usual two nibbles/byte to one nibble/byte
REM Example: 62 2b b0 -> 02 06 0b 02 00 0b
REM the source should be called nav.bin, the destination nav2.bin or change the names and length below.   


Dim A%%, B%%
Open "nav.bin" For Binary As #1
Open "nav2.bin" For Binary As #2
For n = 1 To 131072
    Get #1, , A%%
    B%% = A%% And &H0F
    Put #2, , B%%
    A%% = (A%% And &HF0) / &H10   REM: shift original byte one nibble to the right
    Put #2, , A%%
Next n
Close 1, 2

Then you should go to the emulator (file/settings/memory) and point port2 file to your converted file, probably it shouldn't matter but I'd mark it nonwritable. Finally do a ON-C to attach.

Hope it works for you.
