In another thread I was working on setting up a CF card on my Tandy 1000HD. With the forums help I was able to get that computer successfully working with a CF card as the new hard drive. I ended up purchasing two different XT CF adapters because the first one I bought took up two slots and I only had one slot left in the Tandy 1000HD. I bought the second adapter that only used the one slot and I was able to take this other adapter that requires the ribbon cable and bracket and put it in another computer. It worked initially. Until this morning.
This other computer is a Leading Edge Model D DC-2010E. The CF adapter is the Lo-tech ISA XT CF adapter rev. 3 by TexElec. Along with the add-on ribbon/bracket CF adapter. While I was learning how to set this card adapter up with my Tandy 1000HD I moved it over to this Model D to test it, using another CF card. It all worked. But I did have to disable the RTC on this Model D using a motherboard pin setting. After successfully using this card on this Model D I put it back in the Tandy 1000HD and it worked in that machine for about a week until I got the second card. Then I moved it back to this Model D and had it working with a CF card and booting DOS 5.0, until this morning.
This morning I turned on this Model D and it would not post. The power light came on the monitor and the PS fan was on but no post. I left it on for awhile and when I came back it was still powered on but no post and a blank screen. I turned it off and started to open the case. When I moved the monitor off the case I thought I smelled something burnt. I thout it might be the monitor with some dust. But when I went to remove the XT CF adapter I noticed it was VERY hot. I removed the card from the ISA slot and placed it on the table. Then I rebooted the machine and this time it posted. I had suspected the XT CF card was interfering with the post and this seemed to confirm it.
When I went back to the XT CF card it was cool but I noticed a mark on one of the ISA interface pins and it looked like the traces on the card were discolored. I turned it over and noticed the lable was black (the label used to be white). It dawned on me that this was what I was smelling. The label was burning.
So, now I am wondering if this card is burned out and irreperably damaged. Never having experienced this type of thing before I am wodering what will happen if I put this card into another computer. I had thought I would put this card into my Packard Bell VX88 and use it there. But now I am wondering if I should try that or if I muight damage the VX88 in the process.
The card did not seem to damage the Model D. Once I took it out the computer boots up from floppy and works normally. When I got this Model D I was unable to get the hard drive to work and I could not get the controller to work. I am now wondering if this Model D had a bad ISA slot and I ended up burning this XT CF card in that slot. But I don't know how to test this theory without risking another card.
Or, was is likely the XT CF card itself and not the fault of the Model D? Again, I don't really know how to test this without risking damaging something else.
Is it possible that the Model D was at fault and damaged the XT CF card? Or do you think it's more likely that the XT CF card itself was the source of the "burn"?
Do you think the burned label, extreme heat, and discolored traces means the XT CF card is dead? Or might it still work?
