    From the album: pre-MBX

    Here are some interesting pics from 1982 that I got from Mike Langieri on the MB Gemini game system. It was a standalone system which eventually became the MBX for the TI. Note Turtle Maze and Baseball carts, which must have become "Terry Turtle's Adventure" and "Championship Baseball". All the programmers I talked with said they programmed these games in 6802 Assembly and then had to convert it to TMS9900 Assembly in 1983 for when the project became the MBX. Enjoy:

    I couldn't help but think of my daughter who is about to be born. The five spheres reminds me that she is my fifth daughter. There is a story about her if anyone wants to know...

    This is my contraption used to connect my phone to the TI-99/4A cassette (CS1) port, allowing a WAV or MP3 file containing TI program data to be loaded to the TI. The phone must recognize the cable as being a line-level device rather than headphones, otherwise it attenuates the audio to a point where it is barely audible. The two-to-one cable is necessary as both channels are needed for the TI to "hear" the audio. This is a passive device simply connecting the RCA pins to the appropriate cassette port pins, and I have given consideration to building in a low-power amp using the cassette motor line for power. This cable could be also be used for devices with line-out other than a cell phone. The audio files used (WAV or MP3) can be created by loading a TIFiles program into a program like CS1er or Tape994A and saving is WAV. I suppose just about any MP3 encoder could be used, though I use lame's command line program to convert to VBR (variable bit rate) using the --vbr-new option. You might be able to use lame to make adjustments, but I use SOX (SOund eXchange) to make minor tweaks in volume when necessary. You can usually get a 41% increase in volume without clipping. (I have not tried this, but apparently newer versions of SOX support MP3 output.)

    Here's a photo of me in my Cammy (from Super Street Fighter II) costume playing my Commodore 64 DTV, which is an all-in-one Commodore 64 reproduction with built-in games all inside a Competition Pro style joystick. It runs on AA batteries and has an AV output cord which plugs into your TV.

    In my storage room I came across several boxes my parents had kept of my childhood scribblings and musings. I am in the process of going through all of these boxes, making an inventory for the family library, and scanning for posterity. Back in the 80s I decided the TI needed a different kind of controller. The idea was to take a similar form-factor of the oft-maligned TI controller and build in a keypad like the Atari 5200's. This was to provide numbers (for games like Parsec) and frequently-used FCTN keys in the hands of the user. There were two designs originally: one which was identical to the orientation of the TI controller, and this one which was more like the Atari 5200 controller. Being 10 or 12 at the time I designed this layout and not knowing anyone or any way to produce these, this design sheet is all that remains of the idea. Thanks goes to my parents for saving my scraps and scribblings.

    This is my 26-3022 Floppy Disk Controller, with the WD FD1793B-02 replaced with a Fujitsu MB8877A. IT no longer requires -5VDC or +12VDC to operate.
