In 2018, I acquired the following cards, described in one of my other topics at Bought a Tseng ET4000 VLB with communication card with a TI DSP chip and single board computer with an Intel 486 CPU, where the CPU was soldered to the board.
I finally got round to acquiring an Anesty ZD-915 desoldering station and desoldering the CPU, like this topic at Rescuing an Intel DX4 100MHz 16KB WB CPU from an unidentified ISA board.
I were 'listening' to the noisy fan of the base unit, wiggling around the pins, pressing the trigger and 'listening' to the even louder pumping noise, then checking to see if the solder has sucked away. Some pins would not clear, I had to repeat, add fresh solder, flux, repeat, etc.
Eventually, once all pins appeared to be clear, after a couple of hours, I were able to gradually push the CPU out from the back of the board, leaving the following end result.
The CPU then went straight into my Socket 3 motherboard, where I did not have to straighten any pins nor remove excess solder.
Results are to follow in my next post.
My 486 is my real DOSBox, as well as my customised DOSBox!
