The H-8287 card reader and H-8298 card reader were developed as card devices for the HITAC M Series. Speed and other specifications were the same as previous models, but these new readers had many new features.
- They used a microcomputer control system. A microcomputer incorporated into the card reader provided control of all phases of operation, including: exchange of signals with the processing unit of the electronic computer system, motor drive/stop for moving cards, and turning lamps on the control panel on and off. Exchange of signals with the processing unit for connecting to the M Series electronic computer system was more complex than with the 8000 Series, and the unit would be a few times bigger if it were comprised of conventional logic circuits. A microcomputer was used to solve this problem.
- Operability was improved and the systems were made easier to operate by displaying the operation method with lamps. Cabinet construction was improved, and this reduced noise compared to previous units.
- These systems were also designed to enable addition of a channel selection switch. This enabled shared use of a single card reader or punch by multiple electronic computer systems (up to a maximum 4 systems) by selecting a switch added to the card reader.
- These systems had a buffer memory for storing card data.
- Cost was reduced by using wireless connectors.
