Apparently ftp://ftp.parallax.com went away at some point and with it the download for ye' olde Hydra CD.
Luckily, I downloaded it some while ago and have just put it on github: https://github.com/Wuerfel21/HydraCD
If @"Jeff Martin" or whomstever runs the Parallax Github org wants to move it there, I can make that happen.

Thanks! Great idea. There are folks selling used Hydra boards on eBay without the code.
Does anyone know where to find actual schematics for one of those boards? I checked the manual .PDF and it never actually shows full schematics. There are hints all over the place in the document and I imagine reading the source code would fill in the gaps.
What I'd find neat would be for someone to make a Hydra-similar board using the P2 instead. The performance and I/O lines would help it. That would require adapting any code samples to work with whatever adaptation. Things to consider would be things like using different I/O lines, the lack of a character set, different timings, etc.
The Hydra schematic would be a poor reference if one had it. Poor audio filtering, poor DACs, weirdo keyboard circuit, etc.
I have the Hydra kit and CD, pretty cool, the watered basic needs some more commands added. The book has the board schematic in sections. And I have the board to fill in the blanks.
I added commands to Hydra FemtoBasic IRB, needed a "CLS" clear screen. In the DAT added tok61 and in the Pri texec added 189: dsp.out($00). had bugs until I increased the program size. Seems to work OK, now I'm going to add Home, Peek, poke etc.
