Probably - it was a long time ago. When I first built it, it didn't work at all, but I accidentally discovered that freezing it got it going, so I used to put it in the freezer, set up a control systems problem (Routh-Horwitz, etc.) then pull it out and run the numbers as fast as possible before the calculator warmed up and stopped working.

It turned out to be a faulty clock generator circuit - TI supplied a batch of faulty chips - and Sinclair Radionics reworked it. But it was so limited that it only served to make me save hard for that HP-45, and so I didn't use it for much longer. I've no idea what happened to it, but I don't really miss it much.
