Doug, Replaced the original CPU with socket then used a 5V to 3.3V converter adapter with Intel 486DX4-100 writethrough type. My, OS/2 fly, memory checks guns through about 2.5 times as fast and video feel is much better. HD is really now is neckbottle at same transfer rate as before on DX33, when I have finanical means, replace that HD with used decent HD and finish the memory to 16MB. Ram cost me about $50 a pair new and I modified them for presence sense line setup, not hard only needs to add or remove soldered shorting thingys or piece of one or two strands off a wire. I suggest if you want to, find someone who does SMD rework that has hot air rework station to pull the CPU off. That is preferred method then clean out the holes, put in a top-quality 168 pin socket like AMP and go! Jaosn D. PS: Can use AMD 5x86-133 in WT mode and Intel OverDrive Processor Ready has 168 pin, (not OverDrive Processor which is 169 pin type) And most DX2 processors (not Cyrix please!) PSS: Hold on the net card I assure you I will get another $7 US at end of month to add to the $20 US dollar that I got from my birthday. email: jpero(a)cgocable.net Pero, Jason D.

Actually PGA soldered in, all of 168 pins. (!!) And, I had to do hard way by hand with a WTCPS Weller 42W with medium screwdriver (rounded edges type). Man, many hours. Oh, I did to TP 700C to repair that seperated SMD joints and upgraded my LTE 386s/20 w/ AMD 386SX 25mhz and oscillator and that was nearly 3 years ago. Besides, I did many SMD swaps with that tools setup. Love to... Honestly, didn't see or worked on T3400's so no idea, info anyone? Did Tosh. released T3400 models with different CPU's in it? LOL! (blushes) Thank you, Doug! Actually Sept 19th and now 26. Jason D. email: jpero(a)cgocable.net Pero, Jason D.
