I'd like to configure a Heathkit H11 as a *small*
PDP-11 with just CPU
(M7270 LSI-11/02), terminal, and paper tape. I have no cards for it now,
but I've got the M7270 on order.
It works just fine... I configured my H11 box with an 11/53+ (KDJ11-D)
processor.
Which cards do I need for RAM, serial, and parallel
I/O? I know nothing
about DEC buses. Do I need a bus terminator or anything else? Also, I
recall that something about the H11 wasn't DEC compatible, but I don't
remember what it was....
I suggest you get an MXV11-B board. This has some memory, two serial
lines and the boot code all on board. Then you'll need some sort of
disk interface, like RQDX3 (and a couple of disks). You'll need to
find a leprechaun box (external desk-top mounting box for RD series
disks, the kind which go with the RQDX3).
