Product Code : SCL-EELE-13200
Indian Lab Suppliers supplies the 8259 PIC Study Card + FRC (Product ID: 13200) as part of its electronics engineering lab equipment range. It is a plug-in study card for learning the 8259 programmable interrupt controller on an 8085 or 8086 trainer.
Quick Answer
The card carries an 8259 IC that accepts 8 interrupt requests through input terminals and passes them to the processor over INTR and INTA. It plugs into the 50-pin bus of an 8-bit or 16-bit microprocessor trainer through a 50-pin FRC connector, and 3 mm LEDs show data lines AD0–AD7 together with Chip Select, Read, Write, INTA and INTR. Hardware single-step (from an on-board micro switch) and full-clock execution let students follow each bus cycle, and every 8259 operating mode can be exercised. A user manual with sample programs is included.
