Could any one give me (or point me to) information about the [85-90] IBM PC´s series.
Stuff like motherboard and I/O devices to them...
Have a nice day you all!
What models? Here's the XT tech. ref. manual: http://www.retroarchive.org/dos/docs/ibm5160techref.pdf
In concrete, the PS/2 series... tank´s for the link! will be of use!
By the way... Do you know if it is still possibles to find part´s for those pc´s?
Not sure (without a bit of research) about the LSI IC's ('big chips'), but most if not all of the SSI's are 74LS series, and are still available from suppliers such as Digikey and RS Components.
