how to bleed master cylinder?

88TC
I did a complete brake hardware change out.
rear steel lines installed center steel line made.
now I need to bleed the system.
How is the master cylinder bled?
Are there bleed fittings on the housing?
(Front calipers are bled like any standard system.)
(Rears are bled with charged acspoogeulator. key on - pedal down - acspoogeulator pump running.)
But, where are bleed fittings on the master cylinder?
Can I fill the reservoir and then bleed the calipers?
Your help is appreciated Thank you

Thank you all for the replies to my brake question.
Yes TEVES II ABS
Seem like the master need not be bleed? all fluid goes into the acspoogeulator and then to the cylinders?
So, I started bleeding the system as mentioned, but I did press the pedal ALL the way down not 1/2 way. ??
The pump came on and reached full pressure and shut off.
Please note: My lines are rusted but I thought that I had replaced enough of them.
Well, as I was bleeding the rear cylinders the rear line at the front of the car BURST so violently it vaporized the oil into smoke.
I'm guessing because of the 2,600 PSI. 
Is this a normal function? 2,600 PSI in the lines and the wheel cylinders? how does the system handle that pressure?
The rear cylinders did bleed but not with the pressure I thought it should have, in fact not much pressure at all.
So I'm replacing the "rears" supply line with Dbl. beads & couplings. Difficult but I think doable I think.
I'll try again.
Thank you for your future comments.

The Teves II does operate at high pressure but the stock lines, in good condition, can handle it fine. As you've noticed rust can cause problems.

Long of the short is the fronts are bled like any other brake system, the rears are "hold it half way and let the system do it".
