from my very hazy memory, there were only a few CM-1s made. maybe 10 in total outside TMC?

CM-2s showed up at most supercomputer centers in the US, and even some universities. I think Yale(?) had an 8k. there were several at black sites - at least another 8 machines I guess.

so at least tens, but I don't think 100s

Ok, thanks.

It occured to me how cool it would be to pick one up on eBay. Obviously, I didn't find one. (Not that would have actually bought one.) I guess this is why :)

haha - first thing I did when I saw the hypercube/nuerons tshirt was check ebay - no dice!

In the article it's referred to as the "CM-1 tshirt design" so I plugged the first two words into duckduckgo and the first result led me to someone who is selling the tshirts:

Which is actually the same site as the article. It's Tamiko Thiel's personal site.

hey thanks! goes to show i need to step out of my ebay bubble from time to time

I have one and the printing and material quality were very good.

top500.org for June 1994 lists 79 entries for Thinking Machines which is their high water mark, but it looks like most of those are CM-5s with about 20 being CM-2.

So assuming some of the CM-5s are replacements for CM-1 and 2s I would expect they sold maybe 100 machines total, 150 absolute max across all three models.
