Hi,

i m building a big project: its a mini computer:read/write files and print

lcd as a monitor,
small flash eprom as a storage device,
IBM keyboard as inputs
and it will be able to print file on a dot matrix printer
i m using an Intel 8088 microprocessor on board,with uart,ppi and pic

-I need help on interfacing the keyboard (probably using the rs-232)
-Help on how to interface the parallel port to print characters
-and how to use the flash eprom or interface it on the board

If any one has ideas or sites where i can get help, it will be appreciate

thank you for ur time 8)

 

There was a recent post with a link as to how to interface both a ps2 mouse and keyboard to a micro. I was able to find it searching for ps2 keyboard protocol -- I believe it was the top hit on google.

 

Yes thank u, i saw it after posting it ...i found everything i need for the keyboard interfacing...i m more worry about how the flash eprom is use and how to get that printer to printer using my minimal 8088 system :roll:
