Hi again, and thanks very much for the feedback. Here's my take on things--please feel free to rebut!
1) Funny thing about TI/GSI: Paradox must be singularly unimpressed with its efforts, as it is nowhere to be found amongst the Texas tech teams.
2) If you look at the CSA's tech teams in SRTDD, a quarter of them (5 out of 21) have electronics as a specialty. So while it may not happen at the collegiate level, the CSA seems to have no worries about getting its electronics research done by its government (Norfolk Navy Yard, et. al.) and private industry (Hughes Aircraft).
3) As for the CSA's arms procurement, keep in mind its military (absent the navy, primarily built at the Norfolk Navy Yards) is tiny in 1936, and all Great War models at that. They are therefore able to get by on leftover WWI stockpiles, the remnants of that great past industrial burst able to sustain their miniscule land forces during the Great Depression. If anything else is needed, it is imported, primarily from the Commonwealth.
Higgins Industries' 1938 emergence in the game is an early sign of the CSA's economic recovery, as well as its government waking up to the impending world crises and revivifying its domestic arms industry.
(As an aside, that's one of the reasons I previously left Higgins' start date as-is in 1939--it then flourishes only after the isolationist Long Administration is gone. However, now the CSA faces a crisis of its own with Mexico in 1938, making the new start date the more sensible.)
4) One thing to keep in mind about DD tech teams in general is that not every nation is going to do everything well at all times. That's historical, and it keeps the game balanced. The CSA is far from the worst off in this regard. For example, the UK never has more than two specialty matches when researching the land doctrine it invented(!).
It's a bit of a challenge before and after Higgins Ind. exists in the game, but hey, stuff like that makes the game more interesting to me. Just my opinion, but something to consider, I hope.
5) Funny that--I'm a history teacher/author in the South.
