Silicon Graphics Multibus "IP2" board -- PALASM

PALASM is nothing specific to the IP2, but the IP2 does have a lot of PAL devices on the board and it will be useful to read them out and disassemble them using PALASM. So far I have found that all of the PAL devices allow their contents to be read, for which I am grateful.

Currently, my install of PALASM4 refuses to disassemble the Jedec files from my MOD-EMUP programmer, claiming that "Packed file is corrupt". The older version of PALASM on my DOS machine works. It has an option to indicate whether or not a JEDEC file is a PALASM jedec file or not. If I tell it "no", it works fine. I will have to generate a jedec file from a design using PALASM4 and see if I can figure out how to modify my files.

Feedback? Questions? Drop me a line!
