I needn't have worried...
I have found my 'Acron' IEEE-488 interface. It's the normal 'cheese
wedge' case, but the intenral layout is not what you might expect. There
is no PSU at the front as in the second processors, instead there's a
metal plate screwed there. There's a PCB down the left side of the bottom
(it looks to be approximately extended-length single-height Eurocard
dimensions). There's a mains transformer screwed to the bottom of the
case alongside it, with the normal switch and fuse on the back.
I have not compared the circuit in detail to the E&WW article. But the IC
numbers all agree, and from what I can see the circuit does too.
