[TD]Minor corrosion from where I removed the battery. Board works 100% though.
There is a 4 pin header for an external battery. Corrosion will probably clean up just fine (I did not try).
PS/2 Keyboard Connector, and PS/2 Mouse header.
Supports a very large number of 486 based processors.[/TD]

All these boards were tested as working by me before being stored, and I will re-test before accepting money from a potential buyer.
Let me know if you are interested in any. Shoot me a PM with an offer and we can go from there.
