Probably a bit more appropriate for the classiccmp@classiccmp.org list, 
however since you asked here...

Yes, the TZ30 is nicer. There is a "trick" on TK50s that the drive spindle 
has a phillips head screw on it that you can get to from the bottom of the 
drive when it has been removed from the chassis. Stick a cordless drill in 
there with a long phillips head bit and you can get the tape rewound.

High speed synchronous serial card? No idea.

>DLV11-J

Standard 10pin DEC console cable. Same as a VAX uses only 4 of 'em. :-) Ok, ok
Pin
  1      UART Clk (in or out)
  2      Signal ground
  3      Transmit Data +
  4      Transmit Data -
  5      Signal Ground
  6      INDEX (no pin)
  7      Receive Data -
  8      Receive Data +
  9      Signal Ground
10      +12V through fuse when using -KA (current loop)

Connect pins 8, 3, and 2 for your standard 3 wire RS-232 cable.

>DRV11

Which one? The basic DRV11 (M7941) is a 16 pin parallel port (and I've got 
three on a VAX that I'm rigging up to light up lights-n-switches :-) 
(Secret project: Run a PDP-8 emulator on a VAX, using DRV11's to emulate 
the front panel with real lights and switches. Film at 11)

J1 is output, J2 is input.
J1 pins C,K,NN,U,L,N,R,T,W,X,Z,AA,BB,FF,HH,JJ are OUT0 through OUT15
         LL - REQ A
         VV - New Data
         DD - CSR1
         P  - INIT
J2 pins TT,LL,H,BB,KK,HH,EE,CC,Z,Y,W,V,U,P,N,M are IN0 through IN15
         S - REQ B
         C - Data Transfer
         K - CSR0
         RR,NN - INIT
CSR0 and CSR1 are outputs, you can use them to externally "decode" four I/O 
ports, REQ A and REQ B are available to generate interrupts from your 
device, DATA Transfer and New Data Ready are used to signal your device 
that either your input has been accepted or that there is new data to read.

That should work. M8044-Dx modules. Make sure they are on the Q slots of a 
Qbus not the C/D slots.
