text: The SDK 86 was an interesting computer. When I was at school at Forsyth Technical Community College about 15 years ago I used one of the SDK 86 boards in classes to learn 8086 Assembly Language and to write programs that would do various things. Usually they were pretty simple things like display an alphanumeric pattern on the LED display. We had an 8088 XT setup to compile code and then download it into the SDK 86 usiing the serial port. It all worked extremely well. It was an interesting computer to learn with. I would not mind having one again.

The SDK-86 (System Design Kit) was the first available computer using the Intel 8086 microprocessor. It was sold as a single board kit at a cheaper price than a single 8086 chip! because Intel thought that the success of a microprocessor depends on its evaluation by as many users as possible. All major components were socketed and the kit could be assembled by anyone having a limited technical knowledge thanks to a clear and complete assembly manual. The system could be used with the on-board keyboard and display or connected to a serial video terminal.
The internal ROM monitor offered the following commands:
**S** (*Substitute Memory*): Displays / Modifies memory locations\
**X** (*Examine / Modify registers*) : Displays / Modifies 8086 registers\
**D** (*Display memory*): Displays memory content\
**M** (*Move*): Moves block of memory data\
**I** (*Port Input*): Receives data from input port\
**O** (*Port Output*): Send data to input port\
**G** (*Go*): Execute user program\
**N** (*Single Step*): Execute single program instruction\
**R** (*Read File*): Read object file from tape to memory\
**W** (*Write File*): Writes block of memory to tape.
