Indian Lab Suppliers supplies the 8253 Programmable Timer Study Card + FRC (Product ID: 13196) as part of its electronics engineering lab equipment range. It is a study card for the 8253 programmable timer/counter, with LEDs on its bus signals so students can follow each programming step.
Quick Answer
The 8253 provides three independent 16-bit counters, and all its input and output pins are taken to terminals and a 10-pin FRC connector; counter 0 receives a clock from the card itself. LEDs show data lines AD0-AD7 and the chip select, A0, A1, read and write signals, and a micro switch allows hardware single-stepping as well as full-clock execution. All counter modes can be tried. The card is housed in a pine-wood enclosure, connects to 8085 or 8086 trainer kits through a 50-pin FRC cable and comes with a user manual and sample programs.
