Okay. A while back, I asked for information regarding upgrading a Tandy
1000 TL computer. For those who don't know what I am talking about, here's
a briefing:
I have a Tandy 1000 TL computer with an 80286, running at 8-Mhz, with 768K
of memory.
The memory has mainly 18+ (I forgot) 256K chips, running at 150 ns.
My question in mind is this: Will the 1000 TL have at least a 10% increase
in performance if I replace the memory with 120 or 100 ns chips, and/or
replace the 80286-8 with a 80286-12?
I know, I know. This is the second/third time I am doing this, but I lost
track of some stuff, and the file version of the replies were 'lost'.
But this time, I need to know. Anyhow, to make me more convinced that this
upgrade will work or not is this: actual use of the faster chips/CPU, OR
from technical information.
I'll mention that replacing the oscillator with a faster one will tend to
speed things up. That much I recall vividly.
Also, if anyone has the Technical books for the 1000 TL, please, I need to
ask you a few things about the motherboard.
Also number 2, if anyone has found a way to read raw-data sound files (i.e.
SoundBlaster, Macs) and then use the 1000 TL/SL's DAC, PLEASE, let me know.
All I have is a program called PLAY.EXE by R.E. Sindelar; it works nice, but
I need programs related to this. If you are out there, Mr. Sindelar, I WANT
to talk to you about your program (possible registration).
Argh...boy was this long...but thanks for reading this, and I appreciate your
advise and help.
Also, I will make a summary for the upgrade and the DAC stuff.

Note that the upper 256K is driven via the video controller, and depending on the video mode you are in, you can have up to 12 wait states on each access (Mode E is the worst). > and/or replace the 80286-8 with a 80286-12? Won't do a thing unless you change the master clock up to 24 MHZ (to drive a 12 MHZ part), and replace most of the support chips including the custom ones. They were all designed to work at 8MHz, and if they happen to work as 12MHz, you are just lucky, that's all. Nobody designing those parts said "someone might bump the speed up to 12 MHz, better improve the design to handle it". :-( If you change the CPU speed, then you really will have to put faster RAM in. >Also, if anyone has the Technical books for the 1000 TL, please, I need to >ask you a few things about the motherboard. Tandy does have a technical reference that is ok. You can order it from a store or directly from National Parts. Frank Durda IV <uhclem@nemesis.lonestar.org>|"How do I know?
