Backplane connectors were soldered to a custom PCB. It wasn?t a stock DEC backplane.
Boards have to be installed ?serpentine? I believe.
I have an H11 in the attic. Don?t use it much any more now that I have an 11/23+ in the
shop.

As far as I knew it was a real DEC CPU Module. I expect any application
that ran on RT-11 on the LSI-11/02 would have run on the H-11 but then,
you couldn't just walk into your local computer hobby shop and by RT-11
software. :-)
Yes, it was a totally stock DEC LSI-11 CPU, but most of them
didn't have
any other
Dec components except the backplane. All the memory, serial and printer
interface cards
were made by Heath.
