I got mine in 1981'ish and got a Speech Synth, Data recorder, Munchman, Alpiner and a TEII with it. Later on I would find out that a friend of mine also had a TI, with Extended Basic and Joysticks. I was very envious!. Till I found out that someone who I met through a computer club had a system with Expansion Box.
I finally got Mini Memory and Personal Record Keeping in about 82 ish. I never got Extended Basic.
Back in those days, I wanted something different from my friends (They had ZX Spectrums, Vic20's and C64's). My sole reason was to learn BASIC. In South Africa we struggled to get material for the TI, and I remember I had to order C. Regena's Programmers Guide to the TI book from the US.
Luckily, our local newsagent sold Compute Magazines, and I devoured them.
We only could get beige systems, and I always wondered why the friend's PEB was grey, and my Speech Synth also grey.
I sold my TI later on, and am now looking to get one again (Wink wink.... Who has one to sell?) Now, I am just relying on Emulation to keep me happy.
