30 .Nd parallel printer driver for Creative Systems Inc. Hurdler CPI Nubus card
38 interface provides access to parallel printer ports.
43 interface supports the Creative Systems Inc. Hurdler CPI Nubus card,
44 which is based on a Zilog Z8536 CIO.
47 The parallel port on the Hurdler CPI card is wired as follows:
48 .Bl -column "/STROBE" "Page error" "SubD pin" "Z8536 pin" "Z8536 signal"
49 .It Sy "Signal" SubD pin Z8536 pin Z8536 signal
50 .It /STROBE Strobe 1 22 PC3
59 .It /ACK 10 21 + 11 PC2 + PB3
60 .It BUSY 11 19 + 14 PC0 + PB6
61 .It PE Paper Error 12 20 PC1
62 .It SEL Select 13 13 PB5
63 .It /AUTOFD Auto Feed 14 12 PB4
66 .It /SELIN Select \&In 17 10 PB2
69 The Z8536 INT line (pin 24) is wired to PB7 (pin 15).
77 .Tn IEEE Standard 1284-1994
90 .Aq hauke@NetBSD.org .
93 The Hurdler CPI Nubus card does not use a TTL buffer to
94 drive the parallel interface.
95 Instead, the card's Z8536 CIO drives the printer port directly.
96 Printers terminating the parallel interface with less
97 than 2 kOhms may cause permanent damage to the Z8536 CIO.
