It looks very close to Satans (Minions) free font by Mickey Rossi,
with a modified |A|

Next similar is Moria by Russ Herschler (Free for Personal Use)

and there is also another similar [could be the original one], VTQuadrata by Susan Townsend (Vintage Type, 1996) which is referenced in Luc Devroy's "Hacker fonts" page

I found them using Find my Font - http://www.findmyfont.com

I think Satans(Minions) and Moria are rip-offs of a commercial font, so please don't recommend or use them.
