     Is this newsgroup still active?  I tried reading it after I found about
the TI discussions being moved here and found nothing.  For starters, I just
built a 32K expansion RAM for my TI 99/4A and found that it seems to play
merry havoc with TV reception.  Wrapping the box in aluminum foil seemed to
not help at all.  Any {hopefully inexpensive/free} ideas to help me cure this?

     The memory map is thus:

       0000 -> 1FFF     Console ROM
       2000 -> 3FFF     Expansion RAM low bank
       4000 -> 5FFF     Peripheral Driver programs
       6000 -> 7FFF     Cartridge space
       8000 -> 83FF     Console RAM
       8400 -> 9FFF     Speech Synthesizer,Video Display Processor
       A000 -> FFFF     Expansion RAM high bank

     What does BASIC put in low Expansion RAM?  If it is available to me, then
I should see "13298 STACK
	      32000 PROGRAM BYTES FREE" instead of "24XXX PROGRAM".  I am very
curious about this.

     For the purposes of discussion, it may be advisable to send answers to
net.micro.zx.
