Bar code update...Lance Locklear writes: "I downloaded & printed the hi rollers file on a laserjet 5L. Most lines scanned in first time, a couple required multiple takes, but I was able to successfully scan in the entire program in under 2 minutes. Great job, I hope you continue this with your other 41 files."

I'm also looking for HP-41C calculators and Peripherals I'm looking for old HP-41C's with serial numbers of 1938AXXXX or smaller. The serial number can be found on the back side of the calculator. Peripherals I'm searching for include HP-IL printers, disk drives, and RAM disks.
