Both the Model III and Model IV used the Z-80 chip. the III ran at 2 Mhz, while the IV ran at 4Mhz. The III had a 64x16 screen, with a maximum of 48K RAM. The IV had a 80x24 screen, and could handle 128K RAM using bank switching. -- ------------- Michael Tighe internet: mjt@super.org uunet: ...!uunet!super!mjt
