>>Your thinking of the Heath H11 which was in fact an LSI-11/02. But it had none DEC hardware peripherals like the console SLU and disk controller.
IT was an LSI-11/03. The 03 card had 4kw or ram on it and
was quad width where the /02 card was dual width and no ram.
>>By the way, they were not the only non-DEC LSI-11 system. The Terak also
was an 11/02 with custom console and disk hardware.
The list of companies that also shipped the base dec hardware repackaged is rather lone and includes Charles River, ISI,
DSD, Tektronix and likely many I missed. DEC sold those boards
(cpu and supporting) as peice parts for the embedded systems
of the day to people that did NC mills, gas analysers, plant controls to name a few. It's part of the reason why PDP-11
Qbus hardware is so common and still in widespread use.
