Nice to meet Martin, Joke, Zander (hopefully), Bart W., Bart G., Joost, Stan, Vincent, Elke, Tony, Theo and... again ;-) Seems that Harm-Geert Muller (HG van de proefjes bij Van Duin !?) is a real veteran! Usurpator II (?) already participated in 1st (Official) Dutch Computer Chess Championship 1981 (also with Theo's Storm '81), 2nd Dutch Computer Chess Championship 1982, 3rd Dutch Computer Chess Championship 1983, but Usurpator (without II) in 5th Dutch Computer Chess Championship 1985 - Group A!, 6th Dutch Computer Chess Championship 1986, 7th Dutch Computer Chess Championship 1987 and last time 10th Dutch Computer Chess Championship 1990. The Matchbox CPU (zelfbouw 6809), a 16-bit one. Wow - what a great CPU for that time, compared to the 16-bit Intel 8088/86 segmentation crap. http://www.cityofberwyn.com/simulation/processors/6809/ http://www.cpu-world.com/CPUs/6809/ ------------------------------------------------------------------------------ Motorola 6809 microprocessor family Year: 197? Enhanced version of the 6800 8-bit microprocessor, Motorola 6809 added many new features: * New instructions for loading effective address into registers and exchanging the contents of registers. * New stack handling instructions, including instructions for saving and retrieving the contents of one or more registers to/from the stack. In addition to the system stack pointer the 6809 includes additional user stack pointer. * New Direct Page register was added to enhance direct addressing mode. * Indexed addressing of the 6809 was expanded to provide new addressing modes: indexed addressing using one of 4 registers (2 stack points, X index register or new Y index register) with 5-bit, 8-bit or 16-bit offset, indexed with accumulator offset, indexed with auto-increment or auto-decrement by 1 or 2, and relative to program counter addressing. * 16-bit relative branches could be used to build larger position-independent programs. * 16-bit data processing. The Motorola 6809 was produced in two versions - with on-chip clock (6809) and with external clock input (6809E). Second-source manufacturers: AMI, Fairchild, Hitachi, SGS-Thomson, Thomson ------------------------------------------------------------------------------ Also fine to have Jaime and Daniel as newcomers! I don't exactly understand the 19.15 social event for "old" participants. Isn't there time for that during the whole tournament in the bar or in the evenings after the last round per day in Haagsche Schouw or down town Leiden? It would also be nice, and there is still some time left, that some other join us as well, Bas, Frans (with x86-64 Quest?) ... See you, Gerd
