CC40 Updates and Scans
The CC40 Page
has been updated, and some document scans have been added:
-The 'Guide to Programming the CC40' referenced on the CC40 page had been scanned and is available as a PDF.
-The CC40 User's Guide that has been available as a download for some time now has been cleaned up quite a bit. Each PDF page used to have two facing pages from the guide, but they have now been split so that each page from the book is now on a separate PDF page. Pages have been rotated 90 degrees clockwise and also de-skewed so that they can be read more easily on a computer screen, and I also cleaned up the pages quite a bit by removing specks and other junk.
Links to download the PDFs can be found on the CC40 page, or you can find them in the book/manual sections of the 99er Download Database.

TI-99 Database / File Dump
I've started building a database of TI99 hardware, software and literature. You can read a little more about it in the forum
, and you can check it out at: ti99db.99er.net
I've created a sort of 'file dump' at as a place to quickly upload files before I get around to adding them to the regular download section with a full description, file info, etc. The file dump has minimal descriptions (if any), but the filenames should give you an idea of what they are. Right now, it's all manual scans in pdf, and Win994a floppy images. The images in the 'Micropendium' directory are all disks that I received from John Kohler of Micropendium after the magazine shut down. The file dump can be found at : www.99er.net/filedb.

There is finally a TI-99/4A emulator available for Android phones. You can download it from the Google Play store

RaspTI: Convert a Vintage Computer (TI-99/4A) into a RaspPi Workstation
Matthew Epler created an Instructable documenting his project of turning a TI-99 console into a Raspberry Pi workstation. On the one hand, I hate to see a TI pulled apart and used only for the shell. On the other hand, I find the project interesting because in part 1, Matthew shows how to interface the TI keyboard to the microcontroller. Actually, I\\\'m not sure if the other parts of this project are going to be finished since part 1 looks like it may be at least 11 months old.
Here\\\'s the link: www.instructables.com/id/RaspTI-Convert-a-Vintage-Computer-TI-994A-into/

New Version of V9T9 Emulator
Many years ago, Ed Swartz released the final version of his TI-99/4A emulator, V9T9. That version ran from the command line in DOS or in Windows with a front end. A month or so ago, Ed released his latest public version. It's written in Java, and can therefore be run on many different machines. The interface is very polished and even supports drag and drop cartridges! You can download the new version from Ed's website at http://eswartz.github.com/emul/
. If you're interested in the old version, you can still download it from this site in the download database

New Manuals, Win994a Disk Images and Videos

FC5025 5.25" Floppy Controller
I purchased a FC5025 controller from Device Side Data
, and have been using it to convert all of my old TI-99/4A 5.25 floppy disks over to Win994a format.
The FC5025 connects between your 5.25" drive and your PC via USB. The included software can read several vintage computer formats including the TI-99/4A. You then use it to make a disk image that is compatible with the V9T9 emulator (which is the same as the Win994a disk image- just change the extension to 'TIDisk').
The whole process is pretty seamless and takes only few seconds per disk. It's the easiest way I've found to convert them.
I have begun converting my collection of disks, and uploading them to the Win994a disk section of the download database
. Check back for new additions.
