I don't mind the SD and T machines being converted to MH because Atari actually did release full conversion kits to do exactly this back in the day. Since Atari conversions officially existed, I don't see the harm in converting an SD or T into MH. The kits included the game boards, the control panels with new controls and artwork, new marquees, and new sideart medallion style decals. The only real difference between my SD machine (and the T machine) shown above and a genuine Atari MH conversion is that they have full body MH artwork. Granted, it's fantasy artwork, and of course you'll either like it or you won't. I happen to like it. If we're nitpicking, then I might as well point out too that the official SD conversion control panel used a Tempest spinner, not a roller. I made the choice to go with the roller because I wanted to get as close to the original MH gameplay experience as I could. I didn't have the luxury of having enough money to buy an original dedicated MH cab and I don't think that repro cabs and their related metal parts and artwork were available at the time that I was working on my SD conversion. Of course, in the years since then, the situation has changed dramatically with respect to what cabs, parts, and artwork are now available. Since I went with the fantasy cab artwork, I decided to also add color-changing chrome-rim buttons, and chrome T-molding. I also made a custom LED controller that lights the roller and makes it pulsate when the roller turns. These minor changes are easily undone in just minutes if one is so inclined.
I really do not care if some people don't like it. I don't take it personally. Nothing pleases everyone anyway so it's expected. I happen to very much like the look of my SD conversion machine. It plays beautifully and I enjoy it. I feel lucky and privileged to have it in my vector collection. I also have a very nice SD, an SD to Black Widow conversion, and an original Gravitar. Most BW machines are factory converted G cabs.
