On November 15th, 1991, we received the first order for a software product developed by Tango/04 Computing Group. The local electricity company, Hidroelectrica de Catalunya, was keen on going forward with VISUAL debugger, which I had been coding alone during most of that summer.
I’ve just seen the date trying to rescue the large bins full of old invoices from destruction. It’s good to see those familiar pages again. I’ve also noticed that we had sent a couple of faxes to Antonio Ariño, our first customer (thanks for the confidence, Sir!), with information on completely unrelated matters that he was interested in. Hey, we were always trying to add value.
20 years and two days from the first order, and I have nothing but appreciation for all the people that made Tango/04: teammates, ex-teammates, customers, partners, suppliers, fans, everybody.
Thanks and congratulations to you all.

Congratulations for those 20 years. I miss those days. I remember when we connected for the very first time the company to the internet!!! We paid what you earned or more for a simple modem connection running all day!!
It is difficult to imagine how someone could produce anything related to knowledge back then without google.
Man, I’m getting old!!
Either internet was expensive these days, or I earned very little! Thanks for your kind words, Edu. And thanks for your efforts at building Tango/04.
(See how difficult is it, to think there was a time without Internet?)
All the best.
Congratulations on your 20 years Raul. I have known you since the good old days and it’s great to see you and your company still strive the way you do. It’s a pure reflection on you as well as your team. Keep up the great work and all the very best to you and everyone at Tango/04, especially the ones that I have had the pleasure of associating with.
Sincerely,
Frank Carzoli
Dear Frank, it was always a pleasure dealing with you and so many other suppliers, distributors, partners and teammates that eventually became friends along the way. I was honored with the company of all these people – and yours. It was a great ride because of the people. And it is only beginning. Thanks!
