Where did the "4" come from in 99/4A?

Thu May 25, 2017 12:10 PM

So I had a random thought yesterday.  Where does the "4" come from in TI-99/4A?  I know:


TI = Texas Instruments

99 = reference to the TMS9900 CPU in the computer

4 = ?

A = reference to the 9918A VDP used in the "4A" to distinguish it from the "99/4" which used the 9918 (no "A") VDP.


I can't come up with anything for the "4"...  This has probably been discussed before, so obviously I did not do any searching before posting. ;-)

The F18A is back in stock for anyone who was waiting on one.  Please note that it might take me 4 to 5 days to fulfill orders and get them shipped, so please be patient if you order one.  Thanks!




TI ARC format?

I received this request from a TI99er:


"Any Chance you could put your software together in a TI ARC file for download? Thanks."


Something I never really spent the time to understand are all the TI file formats, so I really don't know how I would go about doing this? :?
