Velhos tempos TK90X
Autor: ghzatomic | Publicado: 2013-06-12T09:50:00-07:00

É meus amigos,

Não sou tão velho, mas participei do primórdio da computação, hj com computadores rapidos, internet movida a fibra, pessoas impacientes por esperar 5 seg para abrir uma página.

Participei da época do tk90x, um computador que na época era o top, com seu processador Z80 (3,58 MHz) em 8 bits.

Meu pai programava nele e eu ficava olhando, lembro até hoje ele com as revistas Input na mão e a minha mãe ditando os programas para ele (Não sabia nem o q eles estavam fazendo).

Foi meu primeiro contato direto com a computação, lembro do meu pai programando e fazendo figuras usando apenas a programação (enchergava aquilo como se meu pai pudesse fazer qualquer coisa ... e pode!).

Apartir daquele momento veio uma revolução absurda na minha cabeça e uma obsessão que até hoje sinto, graças a meu pai e o TK-90X.


Esse ai é o cara, ligado em uma televisão colorida e um gravador de fitas k7 como "HD" ele fazia a "mágica".

Usava-se a tão procurada caixa de divisão de sinal(caixa comutadora).


Sinto até hoje o cheiro do manual e das revistas da Input, devorei aquilo como louco.


Pena que como todo muleque (sim, muleque derivado de MULA), não dei valor no tkzinho e vendi para melhorar meu "poder de processamento"
(mentira, queria saber só de jogar).

Sinto falta desse tempo, quem acha nostalgico ouvir o barulho de um modem 56k discando, não sabe o que é dar LOAD em um programa, apertar o play do gravador de k7 e ir soltar pipa enquanto o programa carrega.

Segue o codigo do Gorilla, que uma vez fiquei 1 mes para copiar ele de uma revista, hj faria com o pé nas costas...
