Игровой автомат своими руками
Кто из нас в детстве не мечтал о собственном игровом автомате? Настало время реализовать свою мечту. Рассказываю, как собрал аркадный автомат своими руками и не сошел с ума. Потому что купить готовую реплику — скучно. А вот переписать NES на ПЛИС, заставить работать монетоприемник, впаять SCART в телевизор, который его не поддерживает, и выпилить корпус из ДСП — это уже приключение. Кому мало «купить готовое» — прошу под кат.

IT WORKS!!!
With a bit of effort I can now receive data from the UART on my keyboard controller, into the CPLD and read it form BASIC on my 6502 laptop revision b (slim version).
I've set the Keyboard controller to output characters from $20 to $7F, here you can see them being shown.
There is also a "new data received" status register too!
-
Well the CPLD UART is coming along, another big step... Now when it's done receiving a byte, it transfers it to a register, which can then be read at anytime by the CPU. So that the CPU doesn't read garbage if it tries to read mid transfer (double buffer).
more to do yet as I need two such registers and I also want the register to be cleared once it's been read, but this is BIG progress.
This is all done in WINCUPL, not VHDL/Verilog.
-
Ok, so, I have the next part working of my CPLD UART... it now populates a buffer, with the correct values!!
Green = serial in (LSB first),
Orange is parallel out (LSB at the bottom)Next step is to transfer that to a register that can be read!
I will probably up my sample clock to 16x, as that seems like the common thing, and 4x may not be 100% reliable. But for simulation, 4x is enough.
-
Fun with WinSim.
After much battling with dodgy tools from the 90s, I've now got two useful signals. One to start the UART receive and it's counter, and one to stop when the 10th bit is received.
Tomorrow, shift register to capture the bits.

Almost back to the beginning! Breadboarding the new Steckschwein "core" based on an ATF1508.
Hope the CPLD has enough space for everything we want to cram in there.
At least hardware based SPI needs to fit. And a vectorizing interrupt controller.#6502 #65c02 #atf1508 #breadboardcomputer #breadboard #cpld #microchip #atmel #wdc

I wonder if anybody has a native Linux version of POF2JED floating around?

Suspiciuously cheap ATF1508 from eBay have arrived. And they indeed _are_ ATF1508, and they work (at least the one I tried does).
Who would have thought?

People doing #Electronics here, I am still searching for a substitute for the LCMXO256C #CPLD. Up to 2019, you could buy these below 2€ a piece on Digikey. They have 256 cells and 78 IO pins, making them quite interesting for that price range. During the pandemic their price raised wildly and now they are 10€ a piece, so I have been searching for a cheaper alternative without success. Any recommendations?

Das EasyGate1541 jetzt auch für die 1541-II
Das EasyGate1541 war bisher nur für die “alte” 1541 erhältlich. Die spätere 1541-II bekam von Commodore ein anderes Gate-Array, das noch mehr Funktionalitäten integriert hat. Es war an der Zeit, dass eine Alternative geschaffen wurde.

PAL видеоадаптер на FPGA с буфером кадра
Наверное, каждый второй разработчик на ПЛИС в начале своего пути пытался визуализировать работу своих схем. Кто-то подключал TFT-дисплей, кто-то — VGA монитор. А у меня под рукой оказался только телевизор с композитным входом. Ну что ж, работаем с тем, что есть!
