CDC-99/4A

[jrhodes]

The Control Data CDC-99/4A's were basically a v2.2 TI99/4A with a different logo sticker, or were they?

Is there any real differences between them and a normal v2.2 unit?

I know some of the v2.2 systems were made in the black style, so how about the CDC's; Are there any black CDC units?

All CDC-99/4A I have opened shown a 99/4QI computer. So the GROM version is 2.2, with a minor modification to display the CDC logo on the title screen.

There was a differing GROM chip (GROM 0) which displayed CDC on the title screen and menu screen instead of TI.

This change is similar to what was done with a modified GROM 0 for some of the Argentine Spanish consoles. The title screen came up in Spanish and the semicolon was replaced with the tilde-n used extensively by Spanish speakers.

(after 1982 TI's V2.2 QI (Quality Improved) version, but I am not too sure how test these limitations like non-TI modules in an emulator).

 

Here you can find the roms for CDC:

Here is the title screen at the left running in the MESS emulation system (nowadays you should run the MAME emulation system).
