Some realizations that I had after being in the “normal” world after growing up in an engineer’s house:
1. Electromagnets aren’t generally toys. Still my favorite one, though.
2. A custom built closed circuit cable TV system that pulled OTA TV from one of several antennas and included a single…

Somehow, a graphing calculator from 2004, the TI-84, is a $140 at my local Walmart. The newer edition with Python was $100.
This is bonkers.

So, another minor issue is that the macro1 cross-assembler doesn't have the PDP-1D's instructions. I have been working on adding those instructions into it. I *think* I have gotten TAD to work.

Some things about digging through the PDP-1 assembler problem:
1. I don’t have BBN’s bespoke version of Midas for Exec-III.
2. The Macro 1962 paper tape image in the MIT seems to be borked.
3. There is a listing of an older version of Macro (and FLINT/FRAP) in the Bitsavers PDFs.

Now digging through the fragments of PDP-1's Midas from Bitsavers in Expensive Typewriter and it appears to be uncompiled. I don't think it's complete (11 out of 25 parts, apparently), but it appears to be the originating version from BBN.

The days of hope and grace seem like they’re gone for the time being. I just hope that they come back.
