need help about designing embedded 8086 system

[ilker]

i have an final project about 8086 system designing,

the subject is decoding 4x4 keypad and writing the number to 7seg displays.

system must contain 8 digit 7seg displays, 4x4 keypad
8255 (ppi) for interfacing, eprom and ram with 8 bit wide databus.

if any one made a project like this please upload.

thanks ..

and for thursday (dic. 23) i have a final exam about this (8088/8086 system and up), and im studing the hardware from this booK : intel microprocessor by Barry Bray.
Actualy the page that i give you is axactly like the book.

I cant give you now the complete hardware, cos i have to study, we can build something after my exam if someone doesnt have a system already build.

I have circuits about, demultiplexing the 8086 too.

Hi Friend I used to develop this type of architectures 15 years ago .The last one i did used a 186 which is a more integrated product .I assume that this is a school project right ? In that case It really doesn't make much more sense to use products that are DEAD .. but if you need help i still have all the programming tools .you should do it with the 88 wich has a 8 bit data bus ,less envolving !

i agree with eltonjohn, the 8085 or 8088 would be easier to work with. with the 8086 the tracks have to be really close and hence the PCB etching process is a bit difficult. and with 80186 it gets more complicated. and then the 80286 and the 80386 and above are out of the reach for a student to do in the lab.

thank you all,

i agree elton
this cant be a microproccessor project,
maybe a historical protject.
