This includes tests, but can also encompass attendance records, registration, schedules, surveys, etc. The 7020 contains a 16-bit mini with 8K memory, a tty for interaction, a cassette drive unit for programming, an output tape unit, a document transport! stacker and optionally a line printer. The read speed is 7000 sheetsl hour and has capabilities for scoring both sides of a sheet simultaneously, provisions for handling truel false or multiple choice questions, and can allow multiple correct answers to questions, if desired. Sixteen levels of discrimination are used to differentiate between valid marks and a smudge or erasure. The 7020 sells for $98,880 or can be rented for as little as $1,3751 month on a five-year lease, including maintenance. A slower model (3000 sheetsl hour) is also available.
