Hmm...Non molto "retro", nemmeno...Per gli amanti di BeOS, più che altro. La
tiratura ( 1800 ) di questa macchina non ne fa un oggetto particolarmente
prezioso, imho. Di "unico" a parte il case, che ha ?
Certo che è pure triste sapere che Be è in liquidazione...

Doppio PPC, Geek Port? L'ultima accoppiata hardware & software della storia
dei personal computer?

Ma bisogna proprio spiegarvi tutto ?
Un pizzico di ingegno..... l'uso accorto dei motori di ricerca......
li hanno inventati apposta !


Se non erro e' una porta per controllare hardware esterno, come, ad esempio
dei robots.

GeekPort
The "GeekPort" is a new feature connector unique to the BeBox. It
provides digital and analog I/O and D.C. power through a 37-pin
connector at the back of the chassis. This port is aimed at
experimenters and small entrepreneurs so that they may bring unique
functions to the BeBox. The GeekPort is located on the ISA bus and can
be accessed by the CPU, a PCI busmaster card, or an ISA busmaster
card.
The GeekPort has the following features:
2 Bidirectional Data Ports Each 8-bit port may be independently
configured as input only, or output with readback. This allows the
user to configure the GeekPort as 16 inputs, 8 inputs and 8 outputs,
or 16 outputs. The data ports are protected against shorts to power or
ground.
4 A/D Pins Each of the 4 pins can be routed to a high-quality 12-bit
A/D converter. An analog signal ground reference pin is provided. The
data A/D pins are protected against shorts to power or ground.
4 D/A Pins Each D/A pin is connected to an independent 8-bit D/A
converter. An analog signal ground reference pin is provided. The data
D/A pins are protected against shorts to power or ground.
11 Power and Grounds 2 pins at +5 V, and 1 pin each of +12 V and -12 V
are provided. The power pins are protected by fuses on the main
processor board. 7 ground pins are provided. The shell of the
connector is connected to chassis ground for shielding.
GeekPort Connector A 37-pin female D-shell connector was selected to
best meet the requirements of experimenters, due to the following
features:
High Pin Count 37 Pins allows for plenty of signal pins and adequate
power and grounds.
Readily Available The connector is listed in most electronics
catalogs, and is available in most shops that cater to the
experimenter.
Mechanically Robust The shell of the connector is rugged, and the pin
spacing is large enough for inexperienced assemblers to solder
connections to the pins. The large size of the connector will allow
many types of devices to be built onto the connector itself or onto a
small PCB directly connected to the connector, or within a standard
backshell.
Not Standard on PCs This connector is not commonly used on PCs so the
risk of plugging an incompatible device into the connector is greatly
reduced. Even if a user accidentally attempts to connect a smaller
connector, the large size of the GeekPort connector prevents more than
a few pins near the end from making contact. The power connections
have specifically been grouped to the center of the connector to help
prevent the accidental shorting between the power pins of the GeekPort
to external cables and devices.
