The SDK-85 MCS-85 System Design Kit was a single board microcomputer system kit using the [[Intel 8085]] processor, clocked at 3 MHz with a 1.3 μs instruction cycle time. It contained all components required to complete construction of the kit, including LED display, keyboard, resistors, caps, crystal, and miscellaneous hardware. A preprogrammed ROM was supplied with a system monitor. The kit included a 6-digit LED display and a 24-key keyboard for direct insertion, examination, and execution of a user's program. It also had a serial transistor interface for a 20 mA current loop Teletype using the bit-serial SID and SOD pins on the CPU. The maximum user RAM for programs and data, on the factory standard kit, was limited to 0xC2 or 194 decimal bytes. The full 256 bytes was available on the expansion RAM. User programs could call subroutines in the monitor ROM for functions such as: Serialserial Inin/Outout, CRLF, Readread Keyboardkeyboard, Writewrite Displaydisplay, time delay, convert binary to two -character hexadecimal etc.

**RAM 256 bytes expandable to 512 bytes with another 8155 RAM / 22 programmable IO lines. The 14-bit programmable Timer/Counter was used for system single-step control. The expansion Timer/Counter was available.

The SDK-86 MCS-86 System Design Kit is a complete single board 8086 microcomputer system in kit form. It contains all necessary components to complete construction of the kit, including LED display, keyboard, resistors, caps, crystal, and miscellaneous hardware. Included are preprogrammed ROMs containing a system monitor for general software utilities and system diagnostics. The complete kit includes an 8-digit LED display and a mnemonic 24-key keyboard for direct insertion, examination, and execution of a user's program. In addition, it can be directly interfaced with a teletype terminal, CRT terminal, or the serial port of an Intellec system. The SDK-86 is a high performance prototype system with designed·in flexibility for simple interface to the user's application.

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.
