MOnSter 6502 (was Re: Monster 6502)

Nitpick: It's not the "Monster 6502", it's the "MOnSter 6502". Eric has added discrete capacitors to the internal buses which has it working better than before. I haven't heard whether that's improved the maximum clock rate.

Re: Monster 6502

What a great idea! Monstrous indeed, in a good way. Somehow I missed it at Maker Faire while I was rolling around with my R2-D2. Hopefully I will see it at VCF West! Marc > On May 27, 2016, at 8:15 PM, Al Kossow wrote: > > Here is a video of it running at Maker Faire > >

Oh sure.. because I always thought that SRAM was intrinsically faster than DRAM, all other factors held constant? On Sat, May 28, 2016 at 9:16 PM, Brent Hilpert wrote: > Fewer transistors, hence less die space. > > Same reason DRAM is more dense (hence larger) than SRAM. > >

Re: Monster 6502

Fewer transistors, hence less die space. Same reason DRAM is more dense (hence larger) than SRAM. On 2016-May-28, at 7:12 PM, drlegendre . wrote: > So what's the reasoning behind using gate capacitance (or inductance) to > store the bit state? It would seem obvious that setting a bi-stable hi

Re: Monster 6502

So what's the reasoning behind using gate capacitance (or inductance) to store the bit state? It would seem obvious that setting a bi-stable hi or lo would be a much more reliable method of saving the state. Is it a matter of power consumption, or switching speed, or both? On Sat, May 28, 2016
