<div>Reading the Wikipedia page about Whirlwind, it mentions that
the pdp1 is a direct descendent, so would a pdp1 assembler work?
Or a tx0 Assembler? I don't know if these already exist or not.</div>

</div>
<div>Is the pdp1 a transistorized Whirlwind as the Wikipedia
article suggests? We already have an emulator for that.</div>
<div><br>
</div>
<div>Anyway, I remember reading about the tx0, and that they were
always modifying the instruction set in hardware. For this early
machine, was there even an official assembler Format? And which
character sets did it use, probably not ascii.</div>

ASCII didn't exist in the whirlwind timeframe; not until mid 1960s.
IIRC, TX0 used a 5 level code from the Frieden flexowriter.
Probably similar to Baudot. Don't know about whirlwind.<br>

yes, the architecture of early machines was fluid...<br>
