This is an adapter to connect a USB keyboard with an Apple IIe.
You can use not only typewriter pairing keyboards but logical pairing keyboards. For example, pushing ':' in logical pairling mode is the same effect as pushing ';' with a shift key in typewriter pairing mode.
Reset : F12
Open Apple: Windows key
Solid Apple: Alt
Reset only works while pushing with a Ctrl key.
I designed this product only for low cost USB keyboards. I didn't do any USB compliance tests. Don't use expensive keyboards. I've tested only with the following keyboards.
SANWA : SKB-E1U (Typewriter Pairing)
ELECOM : TK-FCM007BK (Japanese Logical Pairing)
BUFFALO : BSKBU02 (Japanese Logical Pairing)
DELL : L100
