+====== Michael Kamprath's Retro Computer Projects ======
+====== 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:

+====== Home Built Retro Systems ======
+===== TMS 9995 System =====
+[[https://retrobrewcomputers.org/lib/exe/fetch.php?tok=4c6634&media=https://retrobrewcomputers.org/lib/plugins/ckgedit/fckeditor/userfiles/image/builderpages/kamprath/tms9995_system.jpg|{{https://retrobrewcomputers.org/lib/plugins/ckgedit/fckeditor/userfiles/image/builderpages/kamprath/tms9995_system.jpg?400x400|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 =====
+[[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.

+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.
