Re: another 486 PC keyboard problem
Might be worth a try, yes, I'm just terrified of damaging something. It's almost certainly an AT keyboard. It's really a very small SBC aimed at the industrial 'embedded pc' user, and comes with 'MSDOS-EMBEDDED' on a CF card.
The other pins used on the connector are likely the key (& led) matrix lines for driving a custom industrial control panel, which is how the board is currently configured.
The board, BTW, is from a rather obscure french manufacturer 'Aton Systeme' who, these days, trade under a different name,and specialise in automotive computers. The board type-number is unfortunately the same number as a very popular circuit board inside a very popular Samsung lcd TV, as google is happy to show.
