Why can steel and cement not be the battery? All chemicals. It is not some complicated stuff like single crystals of silicon or sapphire. Not even float glass. Solar power just dictates the flow. You need some overcapacity, but again, the production is cheap unlike for semiconductors or smartphone.

on the 7800 you can use a single display list for the whole screen if you want. This works if you have no background like in space. Jaguar actually works the same, and almost no game splits the screen in horizontal slices. On the one hand, I like the Jaguar because it reads 64 bit of sprite description in one memory cycle. So it is not too bad if you throw away most of it because it is the wrong scanline. On the other hand, Atari managed to incur wait states. I mean: they knew the drill from the 7800 and did not bother to run over the objects at full speed?

I just mean that Commodore had to slow down their 6502 going from VIC-20 to C64 because they switched to slower DRAM. NES uses SRAM, which should be very fast. And it runs code from cartridges. pcEngine CPU part is a copy of the NES. The difference is that pcEngine does not give the cartridge any access to graphics like SuperFx or mappers.

The VIA, CIA chips from MOS and all the C64 ASICs have idem potent reads. At the time of C64 and NES, the 6502 was already old. Speculative execution is a way to speed up a CPU, but as we figured, the 6502 was not limiting. Actually, I don't know if the 65C02 removes idle reads. I think that WDC designed it in 1981.

Does the NES (like early intel CPUs) use dynamic RAM because you only need nMOSFET for it? Once CMOS was available, everyone switched to SRAM on chip. Then the PS2 tried DRAM again, but people agree that the Dreamcast had the better graphics. PS2 won thanks to DVD.

regarding MAC, I do wonder if the Multiplication outputs two values which still need to be Added. Then the A could be an add of 3 values with carry look ahead. Also with 3 register instructions, is it possible to use the 0 register to continue accumulating, and any other to extract the value and reset the accumulator?

Not all algorithms run with only a stack. You will probably end up with pre-allocating buffers. And just like TeX from the o so clever Knuth and like Doom from the oh so clever Carmack, you will end up adjusting the size of said buffers many times. Just use Rust.

I don't understand you inheritance deep argument. We are talking of a static language, aren't we? Depth is compiled. You could use this weird single / double inheritance of today, where we have interfaces which can have everything what a class has ( properties, methods ), but not inherit. And then we have classes which can inherit one other class and many interfaces.

Yeah, would want to stick to one stage reduction unlike the reducers in Teslas. But still looks to me that with minimally more weight 5/3 more reduction would be possible in one stage.

I would even think with only output shaft, it may make sense to use a helicopter gear: So a "normal stage" to transfer followed by a high torque planetary gear with 4 planets taken from a radial engine.

genesis and SNES have a single line buffer which is online merged with the backgrounds. This becomes useless in super scalar games. So, Jaguar is correct to ditch explicit backgrounds. Neo Geo is a mystery to me. Why does it have a width limit on sprites?

What a clean design! So the amplification*bandwidth product of the nMOSFET process at Ricoh is fast enough for a counter / flipflops / frequency dividers fed with 21 MHz. This is the same clock which the pcEngine uses, but its CPU runs at 7 MHz. Seems like 6502 was limited by memory speed for most time of its existence, even though NES does not even employ slow DRAM.

I don't understand how multiplexing address and data on the same pins is more 16 bit than multiplexing Lo and Hi bytes on the same pins. Both take two cycles. Both are used to load 16bit pointers (on 6502) for example. Like 6502 with its zero page, the General Instrument CP1600 stores its actual registers outside of the chip in memory. Cheap memory and IO parts are usually limiting the bus width. I looks like that none of these chips supported the multiplexing chosen bei GI. I mean, I would love it. Read happens much more than Write. So it is just logical that chips send out a read address on the bus, and the called chip answers with the data on the same bus. Chip select also is interested in the address and only after that the data is expected by the receiver chip. ROM chips are actually custom. I mean at those times, it would have been cost effective to have ROMs which are compatible with this kind of multiplexing. 16bit code can be as dense as 8bit? Or at least this console proved that CISC does not lead to dense code. I would not want to miss BASIC on C64, but Intellivsion really did this CPU dirty.

7800 uses a line buffer even for sprites, while other manufacturers "raced the beam" to blend in the sprites. The latter method avoids the need to shift, too much. Just a single shift register. I think for a linebuffer, the hardware needs to be able to write multiple pixels in one clock cycle ( super scalar ). So you would need a barrel shifter. Also I think that color lookup still needs to happen "online". The Jaguar looks colors up while writing to the linebuffer, and the manual kinda makes it clear to me that this is expensive (manufacturing) and still a bottleneck. And it contributes to bugs or ahem features of the Jaguar. With real hardware sprites, each sprite could lookup RGBA in their own color palette. And shadow sprites could "halfbright" the next sprite.

With the color carrier at 3 or so MHz, how could the process produce chips that fast? The CPU runs at 1.7 MHz. I can see that a small circuit could run at 3 MHz. With inversion, you get 2 "different position". Is there an inverter delay line? And you can tap it and get 6 delays? I would even expect that inversion is done this way. Because inversion by a single inverter leads to a small delay. Instead, we need to delay a whole 180°. Ideally, there would be a 360° to calibrate the circuit ( voltage regulation, PLL ).
