          A few weeks back I posted an article about my problems with using  the
          extra  bank  of memory as a print spooler.  I reported that I received
          an "Internal Error" from BASIC and a "43 - SVC parameter  error"  from
          TRSDOS.   I posted the article with the hopes of getting back even one
          response that could get me on the right track.  (I did receive  three.
          One told me his father sold the system because of this problem and the
          other two didn't read my article and told me to  read  the  manual.  A
          warm *flaming* thanks to those two.)

          I did look into the problem further and found out that the  @bank  SVC
          call  returns  an  ERROR  43  when  the stack pointer is not less than
          '7fee'. I wrote a quick assembly language program to  save  the  stack
          pointer  and  called  it from BASIC.  It showed that the stack pointer
          was at 'f632' or there about.  This explains the problem. The stack is
          in bank 1 and the spooler cannot swap out the bank.

          I have written Radio Shack in Fort Worth, and if I ever get a response
          with  a  fix, I'll post it here. The extra memory is great if you want
          the fast disk that the memDISK driver gives you, but if you  want  32K
          of  spooler memory, then you better wait until Radio Shack fixes it or
          find a system that really supports it. Next time I am  going  to  wait
          until the system is out for a few years and the bugs are out.
