About

Today June 24 2015 it's about 35 years ago (summer 1980) I went to a store to buy a computer to write a chess program. I could not imagine what started as a hobby would change the course of my life.

 

The computer was a TRS-80 and for the money (2600 dutch guillders, aprox. 3000 euro nowadays) I got:

 

  • Processor Z80 running at 1.77 Mhz (about 5000 times slower than nowadays average PC).
  • 16 Kb memory (about 200,000 times less than nowadays average PC).
  • Casette recorder for storage. No harddisk, USB stick, not even a floppy drive those days, saving a souce file of 10-12 Kb took about 15 minutes.

 

Not an ideal starting point, but from one thing came another.

 

This website is a summary of REBEL products in chronical order basically divided into 4 sections:

 

  • The Dedicated area of the 80's, Fidelity, Mephisto, Novag, Saitek etc.
  • The MSDOS area of the 90's.
  • The ChessMachine of the 90's.
  • Transporting REBEL as ProDeo as an engine runing under different interfaces in 2003/4 and beyond.
