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.
Thanx,
