I base this possibility on the Wikipedia entry that claims "The newer 17bII+ (F2234A), introduced in 2007, with Sunplus Technology SPLB31A CPU was developed and is manufactured by Kinpo Electronics." This is a similar to the CPU used for the HP-12C Platinum, HP 33S and HP35S, none of which used Saturn emulation. If this is the case, it may be difficult to repurpose the HP 17BII+ platform to turn it into a HP-42S. Performance wise, I don't believe the 8-bit SPLB31A would be a good candidate for Saturn emulation. Its 4288 bytes of RAM would also not be enough to accomodate a HP-42S emulation and 7.2K Bytes of memory space. I would like to know more about the internals of the HP 17BII+ and also if the above assumptions seem to be true. SPLB31A Datasheet: https://www.ic72.com/pdf_file/-/428519.pdf |
