I also added the VT78 to RX01/RX02 cable pinout
Jerome Fine replies:
I have followed this thread, but I am still not sure what a VT78 does.
Is it similar to a VT103 for a PDP-11?
If not, I am curious. The VT103 had a 4 * 4 Qbus backplane inside
a VT100. It could run (within the limits of an inadequate power supply)
almost any PDP-11 Qbus system that could be set up to use just
the 4 quad slots. For example:
M8192-YB
DLV11-J
Camington memory - 4 MBytes
SDC-RQD11-EC (with boot ROM) - Quad ESDI controller
DHQ11 - 8 more serial channels
TQK70
Naturally, I put the 4 * ESDI hard drives on an external PC power supply.
Sincerely yours,
Jerome Fine
