I am using a PilBox (with the PIL-Box Bridge, ILPer and Video Interface) to attempt to load the file HP-71B_OS2CDCC_ROM.BIN to the FRAM71B to allow use of the 2cdcc operating system. Communication between the HP-71B hardware and the virtual components is working.

Hi Mark,

The issue here is that SER2SYS was written for use with the RS-232 interface and the hex dump needs to be in ASCII not binary. HP-71B_OS2CDCC_ROM.BIN, which came from Sylvain's HP-71B Compendium, is intended for use with the Emu71 emulators.

With help from Paul Berger and Bob Prosperi, the utilities in the FRAM71B manual were modified to work with the PIL-Box and hex dumps in the format described in the Emu71/Win manual. Those utilities along with Paul's excellent MEMBUF, can be found in the FRAM71 Tool Kit: http://www.hpmuseum.org/forum/thread-4844.html

The 71B Compendium, http://www.hpmuseum.org/forum/thread-5286.html, has the hex dump in the format to be used with the PIL-Box and Sylvain's loader or the Tool Kit utilities.

Code:

-> HP-71B_SYSTEM_ROM.LIF          ILPER: LIF Mass Storage File / FRAM71
   -> OS2CDCC    ASCII  135K      71B OS Version 2CDCC Memory Dump
   -> OS2CDCCL   BASIC   159      71B OS Version 2CDCC Memory Dump Loader

HTH, Dave
