MS-DOS cross assembler for HP211x machines.

For those interested in a cross assemlber for theHP mini's... I found C source code for a HP 2100 cross assemlber on the HP2100 archive site (which seems to be down today). Not being a C person (that is, not able to read C, much less code in it), I handed a copy over to a friend who tinkers with C a little. He managed to convert the original source into something that would compile on what he described as an obsolete C compiler (Borland?). The resulting DOS code bascially seems to work, with one known bug so far. In the hpasm.lst output file, and instruction that have bit 15 set are listed incorrectly. For example, 102315 will appear as 3777770215. A simple search and replace operation on the listing file corrects this problem. I have not fully verified the binary output, but it appears to be a block-loader compatible tape image. If anyone is interested, I can email them the original C source from the 2100 archive, the modified .ccp file that compiled, and the resulting .exe file. I have scuessfully assembled small programs (blinking lights code of course) with this xasm that matches the ancient hand-written code taped to the inside of the front panel, so its a start anyway.
