Yes....By using a large enough EPROM (one with 16 address lines), you can use one address line for each switch input (max 5 volts).....The EPROM will have 8 data outputs, that normaly you would use as an 8 bit bus in a computer or microcontroler system.....You will then use these 8 outputs split into 2 lot's of 4 to drive the CD4511's (binary to 7 seg display drivers)......Then with the apporpriate code programmed into the EPROM, you can convert and display your result as you wish.....The only problem is, you would need a programmer to do this.....I know that this is a assignment that has been set for you, so if you can do the research on the devices to get an understanding of them, I can give you a schematic and the first few lines of code for the EPROM...If you can then work out the rest for yourself and send me your details, I would be quite happy to supply you with an EPROM programed to your spec''s.... (free of charge)We all had to start somewhere !!!!!!!!!!!......Daniel.
