Found your great project while researching on stack machine and influence on Algol architecture.

I cross posted your site to comp.lang.forth -- perhaps the true successor of B5500, champion of stack machine:

Do come over -- get active -- it is quite active over here. Perhaps the last bastion of the old Internet.

My own LinkedIn, with posts about reverse polish notation programming since about a year ago:

Downloaded and ran your website code -- fantastic, excellent job. Well done.

Thanks for your message and for cross-posting the project to comp.lang.forth.

I should point out that to most B5500 adherents, the true successor is the B6500/6700, modern versions of which are still being sold by Unisys (successor to Burroughs) and used but their customers. The architecture is still stack- and descriptor-based, and Algol is still an important language for it.
