[TriEmbed] what's more basic than assembly language?

[Mike Lisanke]

BTW, using a ROM to sequence data to DMA for driving apps was very common.
I put the phase table for 3Q motors in ROM and use mpu to pull out the
correct A B and C sinusoid values to drive the motor amp.
I scaled and generated the values for the table offline. I knew how to
drive the sine wave. Also, at JC we learned on an IBM 1620 (nickname
CADET). where CADET means Can't Add, Doesn't Even Try. It used
Addition tables loaded in memory from IBM punched card (Holerith was an
IBMer) that loaded the table from the cards at IPL. 🤣
