  First the question:  It is to my understanding that the buss expansion port
on an A1000 is virtually identical to that of the A500 with the exception of a
7mhz clock line, and it's being upside-down.  What I wish to do is compile a
somewhat accurate list of A500 peripheral devices that will work on the
A1000's expansion buss slot in this odd position.  Is anyne using A500
peripherals with the A1000?  If so, please either send me in mail the name of
the device and any problems you needed to overcome, or post it here.  If there
is ample response, I will make the list available upon request.
 
  Now the problem (mine):  It seems that I have some sort of problem with my
parallel port.  While it has absolutely no qualms about communicating with my
printer, it fails to operate correctly (read that - at all) with either of the
2, known working, homebuilt audio digitizers I have plugged into it.  If
anyone has any idea what might be the problem, I would appreciate a response.
One other odd thing I noticed:  Upon inspection of the board in that area, I
was surprised to see a row of green resistor-looking components with their
leads all cut.  Are these things capacitors?  If so, what is their function
and how might they affect the operation of the port?  I did re-connect the
leads, and that did not solve my problem.  I might also add that the previous
owner of this particular A1000 was using a M.A.S.T. Tiny Tiget Parallel SCSI
drive controller on the port (if that should shed any light).

  Lastly, the offer:  I have a Live! 1000 framegrabber that I like, but need
something else a lot more....A RAM expansion for the 1000 that will accept up
to 4 megs (or more) of 1meg x 1 DIPs.  I have these chips just dying to be put
in my Amiga, but no cash at present.  If anyone has a RAM card (or expansion)
that meets this criteria, and would enjoy snapping video images with a Live!
framegrabber, I'm willing to make the swap.  I may be willing to trade for
other fun things as well, so make an offer.
 
A Wholehearted Thanks,
Randolph Turner
