Very Local Network. I have a second machine (Compupro S-100 80286) which is currently collecting dust and would like to network it to my AT-Clone. First, has anyone ported PC-Minix to an S-100 configuration? If so, I would greatly appreciate any guidance in this regard. Secondly, I am looking for an alternative to ethernet for the physical network. Very simply, the cost of two ethernet cards (three if I get an 80386) is more than I want to invest. The approach that I have been contemplating is to use a SCSI bus for the network. Rational: 1) it should be low cost and available, 2) if not available (eg. S-100), it should be easy to construct, 3) it is fast, (greater than 1 megbyte /second), and 4) will support up to 8 devices. On the down side, the physical length of the SCSI bus is limited to approximately 20 - 30 feet. However, my computers are and will most likely remain near one another, so no problem. Again, any thoughts / ideas / guidance would be greatly appreciated.

I have found many scsi host adapters (gateways) that don't support acting as a 'target', i.e. a receiver of commands. The Adaptec AHA-1530 (Multibus I) and AHA-1540 (PC-bus) dont' so choose your adapter well . . .

The title of this particular thread, coupled with the recent announcement
of a 68000 version of MINIX, has got me thinking:
The Commodore Amiga 1000 and 2000 can be configured as dual-processor machine
(in both cases, an 8086 XT compatible running side-by-side with the 68000 base
Amiga). When MINIX gets ported to the Amiga, it will open a whole new vista
insofar as networking within the same machine.
Of course, some details will have to be worked out, such as porting the curren
JANUS library over (what the Amiga uses to control the XT half, if equiped).
Unfortunately, this is beyond my level of expertise.
Yes, I also know that the MAC II series can have an 80286 processor card
installed. Also, whoever is porting this code to the Amiga: please remember
that many Amigas are equiped with 68010s, 68020s. and 68030s, and should have
code upwardly compatible from the 68000 (not too much of a restriction,
really).

I've been considering this for ST-Minix, but it looks like I'll have a shot at BSD style sockets first. (Shouldn't be too much difference between Unix Domain sockets and pipes, eh?) Some of the socket stuff will require the ability to check for a message without actually getting blocked waiting for it. (E.g., for select()...) -- / /_ , ,_.

(E.g., for select()...) > Howard Chu I've already ported Phil Karn's KA9Q TCP/IP implementation to MINIX. Ftp, telnet, and smtp all work just fine over SLIP, in either direction. Since I don't have any other interfaces (e.g. ethernet) I haven't ported to any other devices. For those of you who aren't familiar with it, the KA9Q TCP/IP program was originally designed for packet radio applications, and runs under MS-DOS. Under MINIX it runs as a single user process, and requires only one kernel modification (an ioctl to determine whether characters are waiting on a tty device). Several simultaneous telnet and/or ftp sessions are possible (I've tried 4 with no problem). Phil Karn's TCP/IP implementation is a good one, and I'd recommend that anyone attempting to implement TCP/IP as a server process under MINIX (as I am planning to do) look into it.
