Adding a keyboard and VGA monitor to the Epson IM-403
Not much to it, really. The IM-403 uses a P/S-2 style keyboard. You can buy an adapter at Computer City (or anywhere else) that converts an AT-style keyboard connector to the P/S-2 connector. Or you can buy a new keyboard; most new units come with an adaptor included.
I found a really cool keyboard at Computer City, the black 104-key Windows model by PC Accessories. Great feel to the keys, comes with the adapter, and costs just $19.95.
I had an old VGA monitor laying around, so I just plugged that into the VGA connector on the back of the IM-403; works fine.
