Re: LCC for the Gigatron. Take two.

Great contribution to Gigatron TTL society to make this GLCC available! Floating point mentioned. MIght my fractals with floating point calculation get any faster?

Re: Another Gigatron TTL in Finland

The non-working project. I have put good effort try to fix this, but no function yet. Last try will be use troubleshooting.xlsx to find where faults occur.

Re: Roadmap and status of Gigatron TTL

In a Commodore Amiga 500, you can use PiStorm to replace CPU and it's a raspberry pi with mc6800x0 emulation software. Maybe it also gives HDMI output. Offcourse it has all the bottlenecks of a Amiga, but slightly faster. Maybe it doesn't make any sense with TTL computer. We should be using certain...

Re: Gigatron Clone Ideas

What if someone designed new larger board where all these upgrades are added to circuitry of PCB. You can take the ICs from old board and add them to new plus all the new feature ICs. Larger RAM and ROM offcourse and maybe SSD-chip. SD-card interface as default.

This 1975 mode could make Mandelbrot faster. New Mandelbrot draws in 1min 17sek in fast screen mode.

Re: Lies, Damned Lies and Benchmarks.

Like in the OpenGL programming. You first calculate graphics in a frame and only after that you draw the frame.

Re: Lies, Damned Lies and Benchmarks.

To get real world load to todays computers I modified sieve to "toughsieve" #define size 80000000 #define sizepl 80000001 I get: 10 iterations 8974457 primes Took 11.419000 seconds to execute Your machine is 2.395744 times faster than Win10-X86-PC/i3-4000M(C)-ToughSieve-benchmark Your mach...

Re: Lies, Damned Lies and Benchmarks.

This is little bit OT, but did everybody knew that Cray 1 supercomputer 1970's used only ICs and had 200 000 gates. 1990's they started to use microprocessors. Thanks to sieve now we can compare all the machines. Cray 1 supercomputer(Fortran)-Sieve-benchmark 0.110 seconds. Thats 190 times faster tha...

Re: Lies, Damned Lies and Benchmarks.

Also, did you use the same compilation option -map=64k,hionly as https://github.com/lb3361/gigatron-lcc/blob/master/stuff/sieve/Makefile ? That shouldn't impact the ratios but make the code a bit faster by avoiding long jumps between screen holes.. I only changed -rom=dev, otherwise it was compiled...
