  1. I didn't realize there were aluminum V2.2 consoles.
  2. I asked the question about the nanoPEB version of Mass Transfer so I could use a GuruModem with my nanoPEB. I got the files from palmheads and have attached a DSK. MXNANO.dsk
  3. Code for satellite tracking in BBC BASIC is available at https://www.amsat.org/articles/g3ruh/111.html Most of those routines could be adapted to do basic tracking of a single satellite, which I might do. I'd hate to try to run it in TI BASIC knowing how slow it is. What is the fastest implementation of Extended Basic for the TI?
  4. Quiktrak for the C64 takes a good 10 minutes to calculate a few days of passes for a single satellite, though it's written in compiled BASIC. Maybe I'll adapt some BASIC code that's lurking out there for the TI one of these days, though my skills are not great and it'd be pretty basic stuff, certainly nothing like downloading the keps from the Internet using the TiPi.
  5. As an amateur radio satellite and vintage computer enthusiast, I enjoy combining my hobbies. I am aware of satellite tracking programs for various CP/M machines, Apple II, VIC-20, C64, and Timex Sinclair 1000. Was a satellite tracking program ever developed for the TI-99/4A?
  6. Thanks! Yes, it's a tricky little thing, but I both wanted the case to be as authentic as possible and give such a rare item the greatest possible protection.
  7. As is normally the case when I make such requests, I figured it out within minutes of posting!
  8. Got my bare copy of Dragon's Lair and it's awesome, but I certainly want to protect it! I'm trying to get it into a cartridge shell I got from arcadeshopper. Unfortunately, I can't seem to figure out how to get the door back on correctly. Anybody have any tips (or can point me to any tips for re-assembling the cartridge shells)?
  9. I use an Extron DVS-204 Digital Video Scaler I got for under $20 on eBay with a Dell 1920x1080 monitor hooked up with VGA. The scaler isn't designed for the non-interlaced video, but doesn't seem to introduce any lag or any problems. My TI looks much better on it than composite video from my VIC-20, but you still see some ghosting and significant color artifacting, especially on text which is annoying. Sitting a bit farther away from the monitor than normal makes things look a lot better. It works far better than the $20 Amazon special composite to VGA adapter, but still doesn't look as nice as my dad's setup using a 13" color CRT TV and the TI RF modulator (the TV does not have composite input). The picture on that is crystal clear. Quite amazing for RF. My Commodore 128 hooked up to the same TV through RF looks terrible.
  10. I stumbled upon that last night when trying to put LPC data of my own voice into the TI. Most of what I was saying was just a garbled mess and I noticed in Mark Wills' example program (which I copied - http://www.planet-99.net/wotw.htm)that it started with a standalone >60. I have very little experience with TMS-9900 assembly or anything involving speech programming, so this has been an experiment inspired by that video. It looks like TurboForth might provide an easier avenue to playing LPC data, so I think my next project is to play around with that. The TI-99/4A was my first computer. My dad set it up again after probably 20+ years in storage. I got him a FlashROM99 and nanoPEB for Christmas. Playing around with it briefly while I was visiting made me want my own, so I got one on eBay plus a FinalGROM99, Speech Synthesizer, and nanoPEB and am having a lot of fun with it.
  11. I've attached the assembler code (JFK.a99) and a TI Files format disk image (JFK.dsk). To run, use Editor/Assembler option 3, file name is JFKC. Program name to run is SPEAK. JFK.a99 JFK.dsk
  12. I'll get the code cleaned up (adding some blank text lines so it doesn't print garbage after it runs out of text while the speech data is still being processed) and post a disk image and the code tonight.
  13. Yesterday, after watching the 8-Bit Guy's newest episode on "How Speech Synthesizers Work", which, unfortunately omitted any mention of the TI-99/4A or, frankly, anything about how speech synthesizers actually work, I was inspired to make my own speech on my TI-99/4A. Following Mark Wills's tutorial here: I chose a clip of JFK's "We Choose to Go To The Moon" speech off of YouTube: I then ripped the audio into a mono 8,000 kHz 16 bit WAV. Then I installed Windows for Workgroups 3.11 into DOSBox to get QBOXPro running, generated the LPC data, and put it into Mark Willis's speech program (http://www.planet-99.net/wotw.htm). Then I assembled it with Win994ASM and put the disk image on my nanoPEB's CF card. It's pretty neat to hear the TI-99/4A speak in JFK's voice.
  14. Setting the image print size to 9.25" wide and 1.06" tall was just a tad too long, but an acceptable result. Maybe 9.20" would be about perfect.
