Hey,
It all depends if you bought the sed1335 (or equiv) on its own, in which case you'll need a PCB made up, or....if you got a board already, with the sed1335, oscillator, and ram all ready on it? - These seems to be more available than the chip alone, like 'modules', very handy.
In answer to your question, you'll probably need most of them, however, the circuit can be broken down into four main area's:
1. Connection to the LCD - most likely 9-12 lines, D0-D3, the timing pins, etc..
2. Connection to 'host', be it a PC parallel port, or your microcontroller. This will be 8 I/O's (D0-D7), data latch (E/A), Read/write (R/W) and a reset.
3. Connection from the SED1335 to RAM. It'll need this to hold the 'bitmap' that the LCD is displaying, the SED just refreshes the screen from there. It needs 16 address lines, and 8 data lines.
4. Power and Oscillator. The SED1335 has a couple of power pins, and 2 pins for an external crystal OSC (or you could use a DIP oscillator module).
All the above equates to using pretty much all the pins on the chip, but I wouldn't worry too much, the RAM will take up about half of them, direct connections. In fact, as far as 'external components' go, you'll need the following:
RAM '62256'?
Crystal 8Mhz (I think!) with caps, 2 * 22pf
decoupling caps (100nF * 4)
Thats it!
Theres a quite a few schems on the web, a vast majority of them are for hooking up an 'already SED1335 equipped' LCD to the parallel port, but..there are some for adding an external controller:
**broken link removed** - poor quality
**broken link removed** - small app schem

you can ignore the bottom half of the circuit, as thats for a microcontroller host, note the connection to the SED, a standard 'parallel' port type setup, 8 datalines and a few controll lines.
**broken link removed** - if you use eagle, you can nab the PCB design from this site.

I do have some schems of my own, from a basic setup with just the SED1335 and what it needds, all the way up to a full microcontroller system with the sed1335 on board.....its just a case of finding it, as I've recently replaced my HD and I can't find all my schems
I hope that will keep you going, just ask if you need anything else. You can worry about the 'VEE' circuit later, thats just a circuit to generate -14-22v form 5v, if you plan on powering it all form a single supply.
Good luck!
