A GAL should also be useful--and maybe a bit more flexible. To emulate the OC outputs, one can simply manipulate the output enable so that a '1' output is High-Z and '0' is, well, '0'. I believe individual oput tristate control is allowed in non-registered mode for GALs. A PALCE should also work.
A 20 pin PLCC should fit on a DIP-sized PCB. --Chuck
