OK, let's see how my geriatric memory does (although I usually remember 40 years ago better than 40 minutes ago),,,,
- RF modulator
- external Power supply (depending on when the machine was manufactured, it may or may not have a short "fix" cable attached)
as far as paper...
- a glossy orange 8.5 x 11 set-up pamphlet entitled "Read Me First!"
- the whole punched Green "user reference guide" you mentioned (no, there was no binder)
- two small 3.25 x 8 (?) pamphlets...
- one (black and white except for the words Texas Instruments which were in Blue) was an invitation to join the Texas Instrument Computer Advantage Club
- another (same size, brown cover, about 6 pages) was information on Texnet online services (this one also included a yellow Business Reply Card
- a smaller pamphlet/instruction sheet for the video Modulator
- an FCC warning flyer on radio frequency emissions, and a warning/instruction fly sheet on the power supply fix.
- a blue TI registration card
- an addendum on the differences between the 99/4 and the 99/4A....referring to the difference in particular software manuals
- there might also have been addendums on the disk controller and drive, and further corrections to the User Reference guide
- finally, depending on where and when it was bought, it might have included a Bill Cosby TI software flyer and an edition of the TI Newsletter
(my Canadian Machine came with neither of these in '83, but DID come in a bilingual (French/English) box).
I THINK that's about it...as you can see, besides the hardware, it was all paper..
