Well, the uassembler was a product for a while, so they must have..

I recently had the idea of programming them into an M792 ROM card (100nsec
access time); user programs couldn't have used it without burning a segment
(to map in the appropriate part of the I/O space), but it might have sped up
the kernel some (and it would have been trivial to add, once the card was
programmed - with a soldering iron - BTDT, BITD :-).

Haven't gotten to it yet - still looking for an M792 (I don't want to trash
any of my pre-programmed M792-xx's :-).

Why not just write a Unix-native one? They aren't that much work - I created a
uassembler overnight (literally!) for the QSIC project Dave Bridgham and I
have been working on.

It's been improved a lot since the first version (e.g. the entire uengine
description is now read in from a config file, instead of being compiled in),
but that first version did work fine...

Or was the output format not documented?
