Actually the easiest way to build a 386-based terminal is with MSDOS
(or DRDOS) and kermit. Kermit supports most serial cards and even some
ethernet cards (so you can telnet over TCP/IP). There is even
DOS-based software for mouse support (so you can cut & paste text).
Kermit or DOS can take care of most input and output conversions so
you can talk to almost any system that support telnet or async serial.
BTW since most IDE disk have a spin down feature, you can spin down the disk
just after you load kermit, so you don't even have to listen to the hard
disk. Many systems of that era didn't have PSU fans, so spinning down
the disk made the system totally quiet.

its slots are all 8 bit ISA.
The reason this system will have four COM ports is because in

Hmmm, Linux 2.0 will run fine on such a system, although getting it

I don't think you'll be able to run all four serial ports at the same
time; that is, if they share IRQs you probably won't be able to. I was able
to shoehorn in four on my main Linux system, but I had to give each one its
own IRQ, and modify the serial driver (that was easier for me than
attempting to dig up the required kernel command line arguments).
But since I obtained a Cyclades serial board, I haven't had to deal with
the stock serial ports 8-)

Fortunately, the second serial card has jumpers for using IRQ 5 and 9
as well. Since there won't be a sound card or a mouse, there
shouldn't be any conflicts.

The EtherLink II is quite inefficient as far as ISA ethernet cards go too.
The 3C501 is probably the only thing worse than a 3C503. My favorite ISA
card is still the 3C509B (EtherLink III), but the original 3C509 works
quiet well too.

If you are looking for something with lots of support for network
hardware, Linux seems to be the way to go. Linux network drivers are quite
diverse, and unsupported cards tend to be the exception. I often still
prefer *BSD for dedicated servers, but in those cases, more common
hardware is usually in use.
I investigated FreeSCO, LRP, and several derivatives for one of my 486
router/gateway systems. None of them were exactly what I was looking for,
mostly because the software they contained wasn't up to date. In the end,
I ended up stripping down a Debian install to the essentials, and then
built a custom kernel with support for the different interfaces and
networks I wanted to bridge. I'm fairly sure I could even add 3270 support
to that router if I ever have the need.

You will probably be disappointed, as Coherent never supported TCP/IP.

About a year and half ago I booted the 1.4.2 release of NetBSD/i386 on a
4MB 386DX/25. It was tight, but it worked. I can even remember running
pre-1.0 versions of Linux on a friend's 2MB 386SX/16. I had to
temporarily lend him two 1MB SIMMs for the initial install and a kernel

After looking through the supported hardware list for NetBSD, it
looks like we may have a winner here. Only thing not mentioned is
3270 support, but I can deal with that issue later. Now, I think it
is time to begin Build-0000 of this beast (This is just going to be a

I actually was pretty close to doing this in the late
'80s. The original PC/XT used 2764 compatible ROMs,
and had extra sockets on the MoBo for BASIC. You could
take the BASIC roms out, drop in your own up to 32K of
code, add a magic signature to the ROM, and there you
go. Many XT clones had spaces for these ROMs. So, you
could, with the appropriate firmware, have a nearly
instantly booting terminal. The only useful thing I
made with this idea was a password UVEPROM for my XT
clone, but making terminals did come to mind and made
a really dumb teletype with it. Lots you could do with
32K and a BIOS. BBRAM or flash would have been useful
for storing settings, which I was thinking about doing
with a clock/calendar board and its extra available
bytes.

What _I_ did was to take a $15 Zenith XT laptop with dual 720 floppies,
load on DOS 3.3 (an *original copy*, thank you) with MS-Kermit and the
packet driver for a Xircom PE-3-10BT. There's no hard drive noise,
I can move it around from place to place, and it goes to sleep when I'm
not using it. MS-Kermit's TCP/IP interface is pretty slick - I also
use it to telnet into my Sun server and Lynx around.
What I'd like to do is to fit the PE3 in the side bay where the large
internal modem goes - just have an RJ-45 out the side. For now, though,
it's fine, hung off the back end.

New subject: Rise and fall of MS-DOS floppy FORMAT program
...they can not be set to other values like a true
variable....
Amen. Thanks for the table, Fred!
I remember when I started getting serious about PC's I bought
the v3.30 reference manual. For FORMAT the ref. entry looked
promising. Sectors and Tracks individually settable, for example.
Several dozen (hundred?) possible parameter combinations.
Then by page four of FORMAT: 20 seperate caveats spelled out
over 4 more pages ('The large print giveth and the small print
taketh away') of what you couldn't do. They then included a table
with five possibilities and concluded "No other combinations are
allowed." by now we're on page 8. Oh, thanks for letting me read
all the other B*S* first.
This may have been the very first (for me at least) of the by now
innumerable MS Gotchas

It all seems rather elaborate for a dumb terminal!
Y'all seem to be moving from building a terminal, into building a

The idea did just start out as a terminal for the Cromemco. It's
only natural that it is increasing a bit in scope. I figure that
since I have the old components, I might as well see what kind of
weirdness I can concoct with them. All part of the learning
experience. :)
Why not XTs with serial ports?
This is being built with parts I have readily available. I have a
buttload of 486-33 CPUs, and several 486 motherboards and assorted
video cards, drive controllers, etc., due to my packrat nature. The
surprisingly few 8086, 286, and 386 boards are being saved for future
projects (systems to run classic video games and RPGs from the eras
when those particular systems were top of the line.) The 486 boards
are the most versatile workhorses, and easiest to accumulate at this
time.
If you are THAT hung up on avoiding MS-DOS (I
don't think that
MICROS~1 really got truly evil until about 3.00), why not just write a
trivial terminal emulation program and put it in the bootstrap?
I don't really have anything against MS-DOS. That and Windows for
Workgroups 3.11 are examples of Microsoft's better products (Windows
98 Lite - Internet Excreter eradicated from the system - is also an
excellent OS, and is the farthest I plan on going here at home in the
Windows realm.)
Biggest reason I don't want to use MS-DOS for this project is simply
due to a lack of login/password type security. This is the same
reason I have vetoed FreeDOS, and one of the reasons I decided
against CP/M-86. Additionally, I have plenty of systems running MS-
DOS and the MS-DOS/WfW 3.11 combo; and I am trying to gain experience
points with a variety of different and often obscure operating
systems.
