For these interested on how it looked, I posted a picture of all the characters
created by the HP 2641 APL ROM dumps here:

Now I want to know if you have a list of the Burroughs APL
overstrikes, since HP included many more overstrike characters in the
HP 2641A than the ones that they needed for APL\3000, including (or so
I'm lead to believe) all the Burroughs extended I/O quad overstrikes,
presumably to maximize the

Although he carefully specified 'general overstrike', I'll still mention
how the HP 2641A (an APL terminal) did it. When about to enter a newly
received character into memory, the terminal checked
