Well, after all kinds of warnings, advise, and etc., I DID try the upgrading of the Tandy 1000 TL's memory. I got a friend's batch of DRAM chips, and they are 256K chips running at (or rating at) 100ns. I opened my machine, took out my hard disk, ......... ..... (technical BS and stuff), then out came the original 150ns chips. I kinda figured that this memory setup is weird; but then it is of a non- parity memory, so I needed only 16 256K chips as opposed to 18 (16 = 2 banks of DRAM, 2 = 1 chip for parity ==> 18 chips). (just here for the hell of it) Then I placed the 256K 100ns chips. And then...everything was running okay; HD was okay, bootup was okay. Then I tried various testing programs and procedures. I used Norton SI, PC Tools PCSHELL, CPUSPEED, CPUTEST, and SYSTYPE. No real changes, if any. Then I used a few programs, namely Windows 3.0, and a few games. No real changes, again. Then when I was going to switch back, I decided to test the 100ns chips using RAMTEST. For some odd reason, it registered a 7.7 when with the 150ns chips it registered a 7.2. Kinda odd. So that's it. Oh, I tried to see if HD performance has increased, and nothing. Yeah, that IS it. The memory on the Tandy 1000 TL is definitely fixed at 150ns. What a waste, but then again its a good thing I didn't buy chips -- utter disappointment! Well, the only thing I have in mind now is trying that SOTA 386/Express card, since its supposed to plug directly into the 80286 slot. Oh well.

I tried the refresh rate thingy, and THAT didn't make a big difference, besides the original 8-10% increase in speed.
