I have a garage full of a bunch of computers electronics and assorted stuff
if anyone is interested. Everything must go. Some of the stuff includes:
Ti-99
mac lc II
a monitor
cd rom drives
scsi cards
scsi burner
keyboards
mice
cases
motherboards
cordless phones
headphones
ethernet cables
phone cords
You get the idea.
If anyone, is interested, shoot me an email

Yep, 99-4a. Still in the original box. No idea if it is worth anything or not.
I also have a disassembled adams/colecovision computer that hasn't quite
made it to the garage yet.
My address is 9200 lake meadows way Columbia, mo 65201.
My cell is 573-489-7065. I work from home so I'm usually here
but would appreciate a call before you come.

You never forget your first... The TI99-4A was mine. Less cool or useful than a Commodore 64 or an Apple.

I grew up on the adam then the apples. The TI-99 is one of the many things
of unknown origin that magically appeared in my possessions. Other than
booting it up, I've never really done anything with it unfortunately.
Nope, no dvi monitors. I doubt I have anything that does over 800x600.
I do have a monitor that can switch to CGA as well as between analog and
digital and a bunch of other switches which is quite cool. I used it once to
connect to a predecessor to the 8088.
