Here are some things I want to add to the system. When I think of something else I will add it here. Things on top of the list will probably be added first or are the most realistic.
Things that may be added Why they aren't there already
Connection to PC This is the first thing I'm going to work on, when I have some more time (f**cking school(well actually it's pretty cool)). I want to connect address and dataports to the PC-parallel port so I can test programs quickly. As a matter of fact I have to use this approach because I don't have access to an EPROM programmer anymore.
LCD Display The processing part first has to work OK. I already have enough information on the LCD screen. I connected it to my parallel port which worked just fine so i can use one of the ports from the 8255. (But as you must have seen on the mainpage I just blew it up...)
Serial port (9600bps or higher) Don't know enough about it yet (but I can probably look it up when I have some time)
Battery powered Now (very early design) it already uses 200 mA
7key keyboard The key combinations are copyrighted
Feet (so it can bring me my newspaper) I really don't know
