8-bit PUTEY-1 Breadboard Computer

I've built a 8-bit breadboard computer using TTL chips based on Ben Eater's excellent video series. However, I have extended this design in serval ways. I have made some videos that describe the improvements I have made to the original design:

Additional control lines

Increment registers

64K RAM and ROM Memory Module

Full 8-bit Instruction Register and Control Logic

Stack Pointer

LCD Display

SAP-1 Breadboard Computer

TMS 9995 System

TMS 9995 System

This system is based on the Texas Instruments TMS 9995 16-bit microprocessor. The system was designed by Stuart Conner, and has ROMs for either BASIC or Forth programming.

TMS 9900 System

TMS 9900 System

This system is based on the Texas Instruments TMS 9900 16-bit microprocessor. The system was designed by Stuart Conner, and has ROMs for BASIC programming. It also has the battery-backed RAM, allowing you to persist your BASIC programs, and a TMS 9901 systems interface.

TMS 99110 System

TMS 99110 System

This system is based on the Texas Instruments TMS 99110 16-bit microprocessor, and can run just as well with the TMS 99105 processor. The system was designed by Stuart Conner, and has ROMs for BASIC and Forth programming.
