EPROM One JEDEC compatible 28 pin socket to provide upto 32K bytes memory using 27256 with monitor software.Power Supply Power adapter socket provided.Line assembler/ disassembler, file upload / download options are through serial mode. Monitor Software 16K bytes of user friendly monitor software that allows programs entry, verification, debugging and execution from the on-board keyboard / serial mode.All signals are marked with suitable legends. Bus Signals All Address, Data and Control signals are terminated in 50 pin berg stick for user expansion.Display Six numbers of bright seven-segment displays for address and data.Keyboard Consists of 28 numbers of keys with tops.RST 7.5 and TRAP are available to the user if VECT-INTR & SINGLE STEP functions are disabled. TRAP is used for single instruction step function RST5.5 is used for keyboard operation. Interrupt RST7.5 is used to provide keyboard VECT-INTR function.Counter 1 is used for serial I/O baud rate generation. Timer Three 16-bit counter/timer using 8253 programmable timer.These lines are terminated in a 9-pin D type female connector. I/O Serial One RS-232C compatible interface, using USART-8251A with programmable baud rates through 8253 programmable timer.I/O Parallel 24 I/ O lines using one 8255 terminated in 26 pin berg headers.Provision to battery back the entire RAM (Optional).
