A few weeks
ago I bought a few USB serial port adapters, and they work fine on a
variety of PCs running various versions of Windows. Not, though, on a
Mac, which doesn't even see them.
Did they 'just work' or was a driver downloaded off the net to make them work?
The curse of Windows is every vendor doing things their own way, and the need
for thousands of incompatible drivers. You can extend this to USB drivers as
well. A USB async adapter can be implemented a bunch of different ways, going
as far back as Anchorchips devices that squirted code onto the adapter, up through
the current reduced cost devices that barely offer any tech docs on how they
work.
Vendors really only care about Windows support, and grudgingly give out info
to driver writers (or they have to reverse engineer the hardware to do it).
They also want to lock you into their device, so they have no interest in common
drivers.
Getting back to the original topic, as long as the protocol for the floppy adapter
is documented so that people can write USB drivers for it for other platforms, it
should not be an issue.

A lot depends on the devices and how the OS handles the drivers. I
have two USB to serial adapters that work perfectly under OpenBSD.
When I initially got them they were not supported by the version I was
running, but a bit of googling showed that support was new and with an
upgrade - they just worked.
They are recognised as;
Prolific Technology Inc. USB-Serial Controller, rev 1.10/3.00
One of the things I find frustraiting is the lack of information that
Windows seems to provide about what devices it sees and the logical
arangement of the devices within the computer... However this is
drifting further off topic....

If it is the PC remember -- barely worked.
I still love how crappy the PC I/O is -- you trade a serial port
for a USB hub if I remember how it first came out.
$99 for the cable from the pcb to AT slot. I still don't see any
improvement since the PC is crappy with interupts.
PS. I have digital camera -- too small and too many icons to figure out.

Well, you could also trade the same serial port for IrDA. Now, if
you wanted a serial port, USB and IrDA, you had a problem. :)

What do you want? Old war3z or something new and free?
- Diptrace seems to me the BEST el-cheapo schematic/pcb program. With a
very active developer (there is a maillist on yahoogroups where Stanislaw
Ruev not only fixes bugs but also adds features) and a nice interface, for
me is the winner. Very worthy of a nice and calm look.
- Eagle is nice if you can stand its UI. And the price is quite high if
you want to go above 100 x 80 mm. But it is free up there. Has a linux
version!!!
- CIRCAD hasn't autorouter, but I use it for ages. Fast as a bullet.
- KiCAD is a nice free program, also has a linux version.
With all this stuff, are you still looking for smartdraw and tango
DOS?!?

is no such thing anyways.

But you can't *buy* tango anymore! The big problem I have with the *free*
stuff I have is that you have no 'fingers' for card edge connectors.
The lack of a 84 pin PLCC socket and a windows upgrade have kept me from
doing CPLD stuff. The fact I am still *hacking*1 on a tube amp has limited
my $$$ for a nice computer design, but I did get my PDP-8 clone going
so I can't say I don't have a classic machine.:)
*1 The improved design went *POOF* with lots of smoke ...
I found out later a diode was shorted for some reason in a full wave bridge.
So that is all I have to say on this list about abandonware.
Now to download the CPLD software --- now legacy software for what I need.

Love God for that ;o) You **have** fingers for card edge. If you don't
have, it is real easy to do, take a look in eagle as an example: You need to
do a 0.100" card edge connector. Setup the grid for 0.100", put a SMD pad
with the dimensions of the finger you want, cut it, paste how much you want
in the next grid positions. Do the same on the solder layer (assuming you
were in top layer). Presto, your card edge connector! ;o) I've done lots of
it here. About the 84pin PLCC socket, you have that in eagle. BTW eagle is -
at this moment - the most library-full program you can find, but diptrace is
coming closer, since it can import eagle's libraries, and there is a LOT of
them floating on the net, take a look at www.cadsoft.de. If you cannot find,
drop me a mail and I'll help you. I **don't** like eagle and the clunky UI,
but when you learn how to use that, it becomes easy. I created a component
(a PLCC-44 ZIF socket) and a board in less than 10 minutes, for a PLCC to
DIP adapter.

Dunno why legacy...are you wanting to mess with PAL/GAL? Later softwares
can do that.

It is the pin numbering I looking at here - a little odd in the corners.

That's what I get for reading email and downloading stuff.
Here is a guess for my system speed using LS parts not counting
timing skew and other design features for 6502 style clock.
Clock buffer 15 ns
74LS161 30 ns
74LS158 25 ns
74S472(prom) 60 ns
74LS173 20 ns
------------------
Total 150 ns for 1/4 phase. 600 ns memory cycle max speed.
