hi thankx for your reply regrding duraka, u know on your design, how much info do u want to be displayed eg: name: value menu assign count the letters and spaces,(in this case 16x2) there are dot matrix displays (which do not have letter blocks) and they are good for graphics, they are usualy expencive. but u can draw on letter blocks as well. i cannot count number of characters because it is not turned on (you might find if you press on calculator when it is on you can see the blocks but is it's off, then i guess not) but i'm shure it is __x2 coz i've seen it working and i can tell you the number of pins it has: 16 but only 14 were in use. on the chip seyed: vhc16100 nrb 99-16w jh-99016 and around it was: PM1610-4 PO24 REV:A
