| | ====== 8-bit PUTEY-1 Breadboard Computer ====== |
| | |
| | I've built a 8-bit breadboard computer using TTL chips based on [[https://eater.net/8bit|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: |

| | |
| | 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 ===== |
| | |
| | [[https://retrobrewcomputers.org/lib/exe/fetch.php?tok=dda9bb&media=https://retrobrewcomputers.org/lib/plugins/ckgedit/fckeditor/userfiles/image/builderpages/kamprath/tms9900_system.jpg|{{https://retrobrewcomputers.org/lib/plugins/ckgedit/fckeditor/userfiles/image/builderpages/kamprath/tms9900_system.jpg?514x400|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 ===== |
| | |
| | [[https://retrobrewcomputers.org/lib/exe/fetch.php?tok=e75699&media=https://retrobrewcomputers.org/lib/plugins/ckgedit/fckeditor/userfiles/image/builderpages/kamprath/tms99110_system.jpg|{{https://retrobrewcomputers.org/lib/plugins/ckgedit/fckeditor/userfiles/image/builderpages/kamprath/tms99110_system.jpg?454x400|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. |
