@BobKamman what was that first software? Curious George wants to know. Our first was a Burroughs Mini on lease with a CCH product and 3 part carbon paper copies on a line printer. That was after a few years of UPS to a service bureau - input sheets - send to bureau - want for return - make corrections - send to bureau - .... My first year was tax year 1975 working part time with some other teachers traveling out to people homes. One of the teacher's and a milk man did what you did and wrote there own program and used some computer that I can't remember (along with many other trivial facts.) We is likely very close to the same old(experience)ness
