I’ve been having Zoom meeting with other T/S 2068 enthusiasts. David Anderson, who hosts www.timexsinclair.org, started the meetings. He’s been beating the drum of preservation to the team. He’s looking for Timex/Sinclair books, programs, newsletters, etc. to preserve. Some of the meeting attendees have come up with some good documents. |

| Lunar Eclipses |
While scanning some Capital Area Timex Sinclair (CATS) newsletters I ran across this program that will predict lunar eclipses for a given year. All though I found it in the CATS newsletter, the program was originally published in Sinc-Link newsletter by Mel Richardson. The original code was written by Herbert Raab of Austria, using different |

| Moonphase and Jupiter's Moons |
I’ve done a number of astronomy programs on the ZX81, but really have not ported any to the T/S 2068. I found two programs that would do well with a port and they would benefit from the better graphics on the T/S 2068. |

| T/S 2068 Fonts |
One feature of the T/S 2068 that I had never tinkered with is using a different font. I knew a number of Spectrum games that used a different font, but I had not thought about it on the T/S 2068. The general process is the same on the T/S 2068 as it is on the |

| UDG Character Generator |
While scanning some TimeLinez newsletters, I came across an book review by Walt Gaby of the book “Timex Sinclair Color Graphics” by Nick Hampshire. In his review, Walt included a program that helps define the codes needed with User Defined Graphics (UDGs). Having touched on T/S 2068 fonts (which are similar to UDGs), I thought |

| Wireframe for T/S 2068 |
Back in college I took a Computer Graphics class. One of the items covered was wireframe 3D graphics (well, 3D showing in 2D). I wrote a program for the QL using the technique used in the book from that class. I decided to port the program over to the T/S 2068. |

| ZX81 Fonts |
After tinkering with fonts on the T/S 2068, I was wondering if something could be done on the ZX81 to change its fonts. The ZX81 does not have a way to define a new font, so another method would have to be tried.. Since I am using emulators, the ZX81 ROM is really nothing more |
