I had one of those, built from a kit in 1974 (a bargain at GBP14.95!). Once the faulty clock chip was replaced (apparently TI supplied a bad batch), it worked almost adequately. But the killer wasn't the lack of an Enter key - it was the lack of a 1/x or x<>y key which, when coupled with a 3-level stack, meant that one had to resort to writing down intermediate results.

Still, it's not all bad news - it drove me to buy an HP-45, for which I shall be eternally grateful. Wink
