Very cool! Here's a little FOCAL program that I show as part of a demonstration to our freshmen every spring. It finds the 3-digit numbers that are equal to the sum of the cubes of the digits. C-FOCAL,1969 01.10 FOR I=1,9; DO 1.20 01.11 QUIT 01.20 FOR J=0,9; DO 1.30 01.30 FOR K=0,9; DO 2 02.01 SET N1=I*I*I+J*J*J+K*K*K 02.02 SET N2=I*100+J*10+K 02.03 IF (N1-N2) 2.13,2.10,2.13 02.10 TYPE N2,! 02.13 RETURN * Following up on David's message, I too have seen FOCAL not be able to take code faster than TTY speed. As for the multiple sections, I've had good luck with the version on the tape DEC-08-AJAE-PB. It seems to load fine in a single pass. (Though I have to admit to faking the paper tape.)

All are welcome. Also going to document system in detail, measure voltages, etc. Kennettclassic.com Bill
