It was a rather pretty picture. Tektronix had some fairly nice (but expensive) BASIC machines in the late 1970s and into the earlier 1980s in the 4050 series: 4051 6800 and ~12" perfectly flat screen 1024x768 4052 bit-slice ~20MHz, same screen as 4051 4054 bit-slice ~20MHz, 19" curved screen 4Kx3K Everything in BASIC was 64-bit FP, for which the bit-slice CPU had an opcode for FP add/sub/mult/div. I don't remember whether trig functions were opcodes or done by the ROM. -- Robert Riches spamtrap42@jacob21819.net (Yes, that is one of my email addresses.)
