Yes, the TurboGrafx-16 and the Turbo Express portable. While I certainly preferred my Genesis, as they both launched at the same time here in NA, the TG16 was still a great console with a slew of great games and the ability to pop the games into the portable variant (thanks to the Hucards) was beyond anything like that at the time. I really, really regret selling both of them.

I also owned an Atari Lynx... don't regret selling that at all.  To be fair, the system did do some neat effects like sprite scaling and rotation (the only system to boast these built in until SNES) and it was nice to have a color-screened portable back then but the limited amount of on-screen colors and the washed-out screen hindered any graphical advantages it had.  But its biggest detriment was a lack of compelling games.  I mean, other than Klax (which was fantastic on it), there was pretty much nothing that ever came out on the device that interested me.

No, but my first game systems were a couple of home computers. Home computers were cool.

I have my dad’s Atari 2600 from the 70s. Not sure if it still works but I own it still.

An Atari 130XE. It was technically a computer, but it played the best games to be found in the 1980s outside of the NES, and it also would have been cross-compatible with the 5200 if not for the fact that it had a cartridge slot far too small to accept a 5200 cartridge.

I had an Atari Lynx, to this day it's the only handheld I ever owned. It was an okay machine at best, I didn't use it much, and I got mine for free (another kid gave it to me). If I recall correctly, I had about 3-4 games on it, the Lynx was the first machine I tried that showed that handhelds aren't for me, which holds true today as well.

Growing up, my brother and I were given a Atari 2600 as our first console. Between the two of us, we also managed to snag an Atari Lynx and TurboXpress. The Lynx ate batteries. Like there were times you'd put a pack of brand new batteries into and it wouldn't turn on. It made my Game Gear seem like a battery sipper in comparison. The TurboXpress was awesome, for the time, the screen was immaculate. How/why did we get these consoles, when they were discontinued snapped them from Electronics Boutique at a steep discount. Getting a TurboXpress for $100 was steal. We also managed to get a JVC X'Eye that way. What's an X'Eye? It was Sega Genesis with a built in Sega CD manufactured by JVC.

Lots of good stuff here, keep it coming.

As far as myself, I have an Atari 2600 (which feels like cheating tbh as it was THE big brand in its time) but also a Neo Geo AES which is great, more of a novelty overall but still cool to have, the sprite graphics are incredible.

My brother who I live with has a Turbografx-16 but I don't know if he even has all the gear to set it up, he bought it just as a collector.

The old Arari consoles, including the Atari 2600 and 2600 Junior. Getting it to work was half the fun.. Very different times. 

Atari 2600, Tetris clones and if it counts Commodore 64.

I owned an Atari 2600, which was the best console experience available in the early 80's.  It was so good, in fact, that it belongs in the "big 4" more than either Sega or Microsoft.
