RE: newRPL on HP 39gs

I guess in your tests you never filled up more than half the memory, otherwise it would've crashed. No need to merge the latest, I can see the changes you made on github and are quite simple. I actually want to create a proper folder target-39g (like there is for the 50g), define the constant TARGET_39G, and I'm debating whether I should include stubs for the file system functions rather than remove them completely (to keep the commands visible, so RPL source code can be exchanged between 39g and 50g targets, all SDxxx commands will simply work as if no card is inserted, ever. The same stubs will be needed when newRPL is ported to the Prime too. I did find the RPL code to generate the constants (yes, the tables were generated using newRPL itself), and the paper I took the idea from, although I don't recall much of the math involved to actually successfully modify the tables, so don't expect this to be working tomorrow. What I don't have is a 39g for testing, I can test on my 50g but I'm going to need at least a couple of people to test the ROM thoroughly on real hardware once I release it. |
