This is it! Well, binaries at least.
The binaries for John Toebes / Doug Walker's NET: running over
my parallel port network (ppn) code is going to the moderator.
The project will benefit those people who have two Amiga's and
only one HD, and want their 'other' Amiga to be able to access that
HD instead of collect dust. In simple terms, you string a custom
cable between the parallel ports of the two Amiga's and then use
the NET: binaries provided to remotely mount any volume from the server
machine.
I'll include an example boot sequence and mount list as well as
instructions on how to make the cable and run ppn/NET:.
The current software only works between two Amiga's and you can't
cross-mount. Future releases will work in a real 'network' enviroment...
i.e. more than two Amigas. Also, you can't use the parallel port for
a printer while the network is connected, sorry.
Throughput is 16KBytes/sec+ to a remotely mounted HD (faster if you
have a faster HD, mine are real slow). Raw network throughput is
28KBytes/sec.

This is all wonderful, but I don't suppose anyone has solved the problem of parallel port cable length being limited to 10 feet? I'm about to install Dnet (over the serial ports) on a pair of machines about 50 feet apart, but am afraid that the speed limitations there will render it little more than a toy. I've got enough wires in the walls to do parallel, but I'm sure I wouldn't be able to drive that length very well with the TTL outputs. I'm an EE-type, and the buffering circuit doesn't look easy. We are using the port bidirectionaly here; how might an external buffer know when to turn around and receive instead of transmit? If anyone has an idea, I would gladly try to hack the hardware. Failing that, what do the networking gods (Matt, Doug, John, etc.) have up their sleeves next? Anyone wanna help buy them all CMI/Appletalk boards to play with? --Steve

Matt, do you have provisions >for allocating/deallocating the parallel port, so one can interleave >printouts and NET access? I've been chatting with Matt on the issue, and he's come up with a scheme that would use the parallel port data lines and some control lines from the serial port to control a printer. Thus, you can have either a serial port or a slightly restricted parallel port on each machine. This requires a rewritten parallel.device that can grab the network data lines and use the serial port control lines (yes, a custom cable is required) to dump a burst of data into the printer's buffer, then free the network for normal network-type stuff. I suppose the logical progression is to provide other Amigas with replacement parallel.devices that will send the data to the Amiga with the printer, and maybe do the same thing with the serial.device. But this will all be in the future. For the moment there are minimal hooks in the code to allow the server parallel.device to be written and everything else is "sometime." (Matt, if I've misrepresented your ideas, please correct me.) -- -Colin

This really sounds awsome! I have a question that may be of general interest, though. How far apart can the two Amiga's be? My Amigas are in two different rooms and I'd need at least 50ft. of cable (and that would take some serious work). (I strung cables for speakers between these two rooms and used over 100ft to avoid cutting holes, etc.) If 50ft of cable won't work, I guess I'll just have to rearrange the furniture! This stuff sounds too good to pass up. Thanks, BradCh

I really don't know. You can try it though! 50ft is a lot
of cable. This isn't like a serial cable which has at least
the advantage of high drive buffers, or a speaker cable through
which you pump watts.
The network is fully handshaked so it's only a matter of noise and
the CIA being able to pull down through 50ft worth of resistance. If
it does work I doubt it could be used for more than a link (two
computers) with that length cable.

Then we are in good shape, eh? I just need to finish my device

Don't want to burn out any chips though, anybody ever *measure*
the sink current on one of those long lines?

(what would I need to do to make this work besides kill the network on the printer-Amiga's end?) Will the amiga left with no-one on the other end of the net hang, or just eat some cpu time trying to resynch? The machine with the printer would be the "server" (if such a concept is valid here).
