"Gobots!" is the font Hinge Integrated. "Robo-Toys" is the font ITC Machine (not a Mike Hinge font). "Time Machines" is the font Hinge Computer in italic.
Another example of a Mike Hinge font in practice is a cover mock-up for THRUST, which wasn't published., the source of the image he doesn't recall the website but it was possibly eBay.
Seeing the THRUST logo jogged Alex's memory.
Alex writes, "Mike designed an alphabet based on the logo; digital watches were proliferating and that triggered a need for fonts in that style. I don't recall the name of the font but Mike sold it to PLINC; there must be a contract or agreement in Mike's files. Mike showed a few letters from the alphabet to me; the letters were drawn in outline. Mike said PLINC told him to draw the alphabet in outline; if solid letters were needed, they could easily be filled in. I don't know if this font was ever published in a PLINC catalogue".
