I remember having this work back in the mid-1980s butI have not been able to get it to work today. If I link it with ODT it seems to blow up when the first overlay is loaded. If anyone could help with that I’d really appreciate it!

Thanks Mark!

I remember we had APL at Rose-Hulman when I was in college there from 1978-1983.  At first I thought it was on the VAX-11/780 that showed up over the summer of 1980, but now I realize it had to have been on our PDP-11/70 running RSTS/E.  Probably APL-11 V1.X since it was there in the Fall of 1978 when I started.  We had a couple of DEC LA36's with the APL character set and keyboards.
