"I loaded and run "ZEXDOC" and "ZEXALL" test programs that exercised Z80 instructions. All documented and undocumented instructions are passing but only the quirky undocumented CPIR and LDIR family's IX and IY flags are not correct. This presents no practical problems with any code"

"Once the CPU was formally done, I could run anything, using every instruction assembled and pushed onto my simple "board" model, including some devilish and interrupt-bombardment tests. I also run well known ZEXDOC and ZEXALL tests. They all passed except several weird XF/YF (undocumented flags) behavior for 2 sets of instructions. Those are really weird and if you have ever played with Z80 emulators you would know what I mean. I believe this particular Z80 (mis)behavior is likely a side-effect of internal bus charge/discharge cycles and some spurious control signals since different second-sourced Z80 chips behave differently in these scenarios. I decided not to sweat over it as it had no practical impact."
А пока некто Mark Smith сделал платку на Xilinx, заменитель ULA. Назвал SLAM48, 128+ и т.д.
Вот пост в фейсбуке
Вот картинка, если линк не откроется..

Допиливает как раз.. пишет что:
"Ula+ version is ready it will support all Timex modes too, so mono 512x192 (with ula+ palette), shadow screen at 6000h, and hires (32x192) attributes. The prototype already supports those modes, but a second prototype is needed so as to test a design that uses fewer components."
Интересно какова будет цена?
Учитывая дефицитность и все меньшую доступность.. я думаю что баксов 25-30 зарядит.
Anubis_OD, За границей все цены начинаются от 100$ + доставка.
Не убедил..Сайт sallmyretro имеет много всяких девайсов/девайсиков за более скромные деньги.. но,да, альтруизмом тамошние ваятели не страдают..
