Hi i just joined this group. I recently purchased a TI 99/4a Home computer with a bunch of games and applications. I have been collecting game consoles for a lot of years and thought id try the vintage computers. I got it in the box at a local thrift store. I have been trying to figure out a value on a game called Midnite Mason by Software Specialties 1984. Any help or info would be great! Thank you

Hi everybody. I picked up a TI-99/4A at a garage sale and was looking forward to playing around with it. Unfortunately, it looks as though it has a few problems. the TI splash screen comes up but the text is garbled. 

Ive attached a photo of the screen. Any ideas? not afraid to break out the soldering iron

am cleaning out the warehouse after 43 years. 
lots and lots of new in box old stock 99 4a items.
software. keyboards, expansion boxes, add on boxes, cords, cables, cassette items. modems. 

I will be making a list and photos in the next 2 weeks with a link to the items. 

any thing special any of your are looking for?

Hi folks!

Yesterday I finally added all my scanned german TI-Revue magazines as PDF-files to my www.bromosel.99er.net weblocation.
Still missing is the Assembler-Special.

I did the scans by myself back in 2005 whilst working in a copyshop. My boss made a very good price for it.
Scanning was free, only for the one digital hardcopy i did on paper he charged me 120 Euro.
I sent this hardcopy to an italian TI-user without any profit.

The PDFs on my site were scanned in b/w 300 dpi. Only the titles are fullcolor-scans.
In total it's 365 MB data.
Have fun!

Cheers,
Dirk

I'm sure it's for a printer  especially since it's very similar to the cable shown for the ParallAx TI Printer Interface
and it has the TI logo on it. However, I'm not sure what 16 pin devices it would connect to and I'm not even sure if it is for the 99/4a or for a TI calculator. Any insight would be appreciated. Thanks. Here are some pics:


       

Hey guys i just recently started picking up electronics since i baught a house in the city, now i have thrift stores and space haha

Anyway i got a ti 994a today. Its my first pc older than windows 95. It was 30$

I played with the rf modulator and figured i could wire rca style plugs to the cable, i used 25 foot subwoofer stereo cables to reach my flatscreen

It seams i have video and can hear beeps when i press keys, but i all i get is the color strips, then i press a key and it the color bars dissapear. No text like i see on youtube videos

 Any ideas? Ide appreciate some, Thank you!

Hello,

I still have an TI 99-4a. I don't know, if it still works. Haven not turned it on since decades.
Before I put it in the trash, maybe there is someone who wants to have it.
I live in Germany. So if you are interessted, just contact me.
