I recently purchased a very good condition 1000tx. It arrived i powered it up no probs. So then i upgraded the ram to 768k, and put in a math co. Still no problems. Finally i got around to trying to install a hd in it. It was a big seagate st 225, drive with controller card. At first i put the card in, hooked up the hard drive could hear it spinning but couldnt access it from dos, let alone try to ll format it. So i read around and on the 1000's you set dip sw 2 to off to use any standard controller.
I did this put the card back in and all of sudden a saw a bright pop on the hd controller card. I immediately uplugged the machine as i could smell like something burnt. I removed the controller card and there are some areas that got so hot that it turned the solder to a ball. The next thing i did was look over the mainboard and now when i turn it on, the tx, i get nothing but a bunch of garbled information and it never goes to the memory test nor normal post.
Just to rule out the recent additions i removed, the memory upg, set the jumper back, put sw2 back to on where it was and still the same. The 286 processor feels warm as well as the co processor. Ive read about old computer power supplies taking them out, but i guess this was just a coincidence as last time i put the card and hd in, it posted booted to the a drive prompt. All i was trying to do this time was get the controller working properly and then try to low level format the drive so i could install windows on this old computer. If its something with the power supply i do have another tandy a sx laying around with a good ps in it, well it worked last time i booted it, and could try swapping to it to see if that makes a difference. But i did check around the board and nothing seems blown, swollen, or burnt. I even smelled near the ps area and it was ok, only the controller board i removed had the burnt smell and balled up solder on it.
Thanks in advance.
