You're SORT of on to something there. All of these FPGA boards that recreate Amiga chipsets should have gone way beyond the originals in expandability. Even a multitude of clock ports and a multitude of cheap clock port peripherals would have made some sort of sense.
Is there anyone thinking of next-gen FPGA-based chipsets anymore? _________________ This weeks pet peeve: Using "voltage" instead of "potential", which leads to inventing new words like "amperage" instead of "current" (I, measured in A) or possible "charge" (amperehours, Ah or Coulomb, C).

| STM32F7, An ARM Cortex-M7
"We’ve seen the ~F4 chip pump out 800×600 VGA, drive a thermal imaging camera, and put OpenCV inside a webcam. Now there’s a new, even more powerful part on the market, and the mind reels thinking what might be possible."
"Right now there a few STM32F7 parts out, both with speeds up to 216MHz, Flash between 512k and 1MB, and 320kB of RAM. Peripherals include Ethernet, USB OTG, SPDIF support, and I²S. The most advanced chip in the line includes a TFT LCD controller, and a crypto processor on-chip. All of the chips in the STM32F7 line are pin compatible with the STM32F4 line, with BGA and QFP packages available."
"As with the introduction of all of ST’s microcontrollers, they’re rolling out a new Discovery board with this launch. It features Ethernet, a bunch of audio peripherals, USB OTG, apparently an Arduino-style pin layout, and a 4.3 inch, 480×272 pixel LCD with capacitive touch. When this is available through the normal distributors, it will sell for around $50. The chips themselves are already available from some of the usual distributors, for $17 to $20 in quantity one. That’s a chunk of change for a microcontroller, but the possibilities for what this can do are really only limited by an engineer’s imagination."

Users here could probably move up from the $9 computer to a 200 MHZ Arm computer but you should really think about making space and room for development for new tech on your website if you want the future to go forward for personal computers.

"move up" from 1GHz to 216MHz? Not much of a "move up", is it? And at a higher cost, no less. _________________ This weeks pet peeve: Using "voltage" instead of "potential", which leads to inventing new words like "amperage" instead of "current" (I, measured in A) or possible "charge" (amperehours, Ah or Coulomb, C).

There are faster Arm chips but the development costs are greater. The smaller stuff is something I can afford.
Commodore didn't start with the C-64. They started with the Pet and then the Vic-20.
You develop on the easy and cheap stuff first and then move up to the bigger stuff.

Again, this thing is significantly more expensive than "the first $9 computer" which this topic is about. And significantly less powerful. _________________ This weeks pet peeve: Using "voltage" instead of "potential", which leads to inventing new words like "amperage" instead of "current" (I, measured in A) or possible "charge" (amperehours, Ah or Coulomb, C).

And those who can't program a microcontroller can't program either.
The Raspberry Pi is more powerful but it has less GPIO pins. There is a learning curve with this stuff. Just because it is less powerful doesn't mean that many people here can program either.

Then why advocate the slower more expensive one? _________________ This weeks pet peeve: Using "voltage" instead of "potential", which leads to inventing new words like "amperage" instead of "current" (I, measured in A) or possible "charge" (amperehours, Ah or Coulomb, C).

The datasheets are different. Not everything is about price. The more expensive one has crypto functions and a lot of work went into it already. They have different architectures.
Just as Commodore had more than one line, everyone else isn't set on one microcontroller or product. They have pluses and minuses.
Amiga is tied to individuals who aren't doing anything with the I.P. except strangling the Amiga's future. It is doubtful that some of the old tech can be produced again and the old tech isn't competitive.
New hardware is the way forward.
