Slightly similar is the monowidth version of Avant Garde. I got this with an old copy of Appleworks. I'm not sure of its current availability.

thanks, that's actually quite nice, seems to be available too...

i wonder how it works with optical kerning?

Should be Pottery Twenty by Laurenz Brunner, the creator of Akkurat.
Some loosely similars, (some not monospaced though): Planeta, Underground Pro (using the alternate /a), Twentieth Century, Futura, Geometron, FF OCR-F, LLBrown by Aurèle Sack]], Platform (using some alternates)

thanks ryuk! too bad it's not available. the same typefaces seem to pop up all the time, planeta etc... really looking forward to the release of llbrown though, i guess it should be out on lineto any day now.
