Ive been playing around with this board I got today its a 386 SX/SXL 25 and the Varta battery has chundered all over the shop I removed it and luckily not a single track was broken but the sealer over the tracks peeled off in places and I tried using some fine sand paper and soldering the track but many tracks need just to be resealed, is it true you can use clear nail polish but ide rather use something made for this purpose but I dont know what it is called or where to get it. This is the smallest 386 motherboard ive had does someone know what brand this is I haven't looked up the "8517 Rev 2.1" yet.
