Ten Year Rule

Later, somebody said to me that it was their first production model. It was a lot of fun. It would not have been adequate for aligning floppy drives. I have been told that that calls for dual-trace and 20MHz or higher. Is that correct? Eventually, I gave it to somebody who needed it more than I did, and I got myself a used NLS 215. Still not enough for floppy drive alignment. But lots of fun for other miscellaneous stuff. Eventually, I sold it at VCF. Even I miss having a scope. Can you imagine what the world would be like if NLS had gotten into making computers? :-) They'd probably grow faster than they could manage, and end up trying to expand into tents in the parking lot! . . . and not even know their inventory well enough to know if something went missing! -- Grumpy Ol' Fred cisin at xenosoft.com
