No, that's just the one Asterock that I mentioned before here...
Ray, it's both true. The SI is a big machine, especially the lower part. It barely fit in my car, in which I had transported the Meteor, Centipede, Puckman and Joust with ease.
On the other side, the Asterock is really a thin lady. It's definitely not a mini (it's even taller than the SI) but it has a very small width and it's also very un-deep. (The last thing mainly because of the ingenious CP set-up). I've noticed that European cab builders tend(ed) to keep their machines a bit smaller compared to their US counterparts.
F.I. The Euro Joust and Robotron are a lot smaller than the US version. My (Elektrocoin) UK-built Double Axle was also much leaner than the US version of the upright.
I actually love this as I can use every cm. of space in my gameroom

I still can't get over the fact that there is an Atari sticker on the Electrohome monitor in this bootleg cabinet ! Gotta love that they used the original monitor somehow....
