The 1410 was a larger version of the 1401. I never worked with a 1410, but had a lot of experience with the 1401. It had a 3 digit address that, coupled with bits in the 1st & 3rd position gave it a maximum address of 16,000 BCD (binary coded decimal) characters. I believe the main difference was that the 1410 had a 5 digit address, I don't know the maximum memory size. Also, since it was later than the 1401, it had the ability to attach disk drives with removable disk packs. I don't know the capacity, but the disks on the 1401 I used were 4.7 MB. Since we didn't have an operating system on the 1401 and it was text and numbers only we could do a lot in the 16KB memory.
