I have a few of these, but only one has a 9-pin ext
input. Was curious about it, and I haven't found anything
on-line about it. Was there anything that used it?

I don't have the system in front of me, but if it's what I think it is,
wasn't it for the Mega Modem that never got released here in the US?

You are right on, it was for the modem that was released in Japan but
not here. Technically it';s a third controller port, but no games used
it but for the modem, and those games could also use port 2.

In theory, any game that did use port 3/modem can also use ethernet
with a good adapter as well as port 2. The Genesis control ports are
very similar to parallel ports, very cut down but very similar. One
project of mine is to get a ppt-ethernet adapter working on a Genesis
and write a program that will at least test it. But that's a long ways
off and an old idea now.

So yes, technically the Genesis/Mega Drive was the very first online
ready console of it's day.

I read this and the other and I didn't realize that Sega planned
to put out the Mega Modem over here. I have a picture of the device
attached to a Mega Drive in an old Japanese magazine, but it showed it
attached to the back of the unit.

Man, that would have been interesting to see...

Electrically, it's identical to the two controller ports in front,
except for the connector being of opposite gender. Note that all the
ports can operate in serial mode, selectable between 300, 1200, 2400,
and 4800 baud.

And for what it's worth, the TMSS lockout system was added before they
stopped installing the EXT port connector. A few more revisions later,
Sega removed the EXT port from the circuit board entirely.

This stimulates my collector's urge, as I thought the TMSS occurred at
the same time that the port was removed. Any further variants with respect
to the High Definition Graphics text on the case? It sounds like there's
potentially seven or eight different possible combinations that are
possible in the original Genesis 1 unit.

^ ^ ^ ^ ^

Possible combinations. That are possible. Yeah, today redundant cat is
redundant. Remind me not to post on an empty stomach in the future. :)

I only know it didn't because I have found at least one with both TMSS
and an EXT port. Pre-TMSS units (at least in the USA) seem to be rather
difficult to find in the wild, which surprised me because of the legal
battles that it brought about. (I was looking for one mostly as a
faster-booting dev test unit.)

FYI, if you peek inside the cartridge slot door, there is enough of the
circuit board visible that you could easily identify a pre-TMSS unit.
But I haven't fired up the real thing in months, so I don't have a known
unit handy right now to describe it.

This EXT port was mainly for the TeleGenesis modem, which was never
released in the United States.

You see the modem in the earliest Genesis print ads:

In Japan, the Mega Modem for the MegaDrive was released in 1990, AFAIK.

You gotta love how he shows up a week late for the party and treats the
post like no one else has presented this info.

Attention whore? Why no, Radeon, we don't think you're an attention whore...
