im using an old microwave oven chip 80x167 8mhz on a homemade motherboard with over 50 kb memory !! the hard part was converting the old electric typwriter into a keyboard and my 9 inch rond screen rca victor tv set into a monitor. amazingly it runs xp just fine(good memory compression alogs i guess) its got one of them new fangled 4 trak "cd" tape drives in it so i can download data. -i'll have to upgrade soon though. got an outta memory message the other day. oh wait a minute ... what year is it? i'm HOW old? my how time flies. o.k.
