Remove the drum on the good side and you can see how the adjuster system works. Then use that information to remove the drum on the stuck side.

Excellent advice.
I got it off but I never did figure it out. It does have a star whee but the teeth are such that i don't think i could have backed it off.
I'm not sure where the pressure was coming from. I just kept pounding and prying but it fought me all the way. The E-brake was snug but not tight.
The brakes will get redone and I'll never know.
Thanks for all the input.

If the self adjusters stop working, and as the shoes wear, the piston in the wheel cylinder can end up moving farther out the cylinder and getting stuck in the rust there (and not retracting when you let your foot off the brake). Also, sometimes the flexible hose that connects the wheel cylinder to the steel line can slough off internally and form a one-way valve. Make sure you change the flexible lines when you get the brakes redone.
I was tempted to suggest a gear puller to get the drum off. It would have worked, but could cause some collateral damage and drive up the cost of repairs.
