I found this program but I don't see any mention of allegro.

Is there another name allegro goes by? I found out allegro is by company called cadence.
I did try to read the board file into kicad but got an error.
Cadence bought OrCad so they have bidirectional integration with this:
http://www.cadence.com/products/orcad/orcad_capture/pages/default.aspxAlso Allegro can export to:
–– Capture
–– EDA XML
–– CSV
–– Mentor DxDesigner
–– Design Architect
and import from:
–– EDA XML
–– Si2 PinPak XML
–– VHDL
–– Verilog
–– Synopsys PTM models
–– CSV and text files
–– Die text
–– Pin grids
–– Pin tables
–– Cadence OrCAD Capture
–– Mentor Graphics DxDesigner
–– Mentor Graphics Design Architect
–– Allegro Package Designer
–– FPGA (Xilinx, Actel, Altera)
–– IBIS
–– DML

In the meantime there is a free viewer but that probably won't help you much.
Edit: but in case the viewer helps, here is the official link:
http://www.cadence.com/products/pcb/Pages/downloads.aspxName is: Allegro/SIP/MCM FREE Physical Viewers 16.6
You might find it on other places but I wouldn't trust not known downloads for executables.
