ZX81 expansion


       I've been thinking about buying a ZX-81 to help
       a friend learn BASIC, but I think I could get
       the memory cheaper if I built it myself. Do any
       of you ZX-81 users out there know where in the
       machine's memory space is the expansion module
       located? I'd hate to just guess, because who
       knows what kind of partial address decoding
       and other nasties could be going on inside that LSI chip!
       Please address responses to Mark Johnson at Purdue
       University.

                                       Thanks,
                                       Mark Johnson
