Languages are also given the designation of being “high-level” or “low-level”, depending on how close they are to the base language of the computer on which they run. However, a bug was introduced that allowed PLOTting vertically to areas outside of the double lo-res graphics screen, which would land right in the beginning of the $800 space where the Applesoft program text was located (similar to the “plot” bug in Applesoft I).

When Applesoft II was started up from cassette or diskette versions, the display screen now showed a copyright date of 1978 by Apple Computer, Inc., and 1976 by Microsoft (which may be either their copyright date for the original Microsoft BASIC, or possibly for Microsoft’s first 6502 version). The work was tedious because of the slow speed of the connection; compare this 110-baud speed to the significantly faster dial-up modem speeds of 56K (56,000 baud, over 500 times as fast) that became available years later. ; yes, restore data bank
