Ah, GEOS.  I used it quite a bit when I was a kid -- wrote school reports in geoWrite, made labels in geoPaint, and wrote 6502 assembly code in geoProgrammer.  (Well, technically, wrote assembly in geoWrite and then used geoProgrammer to assemble and link -- a very tedious process, indeed.)  GEOS applications were always a bit of a dog compared to non-GEOS programs, at least for those of us without any RAM expansion.<p>I once wrote a letter to Berkeley Softworks asking for more information about programming in GEOS (API&#x27;s, etc.), and was surprised when I got a huge binder in the mail with a printout of the Hitchhiker&#x27;s Guide to GEOS.
