<p class="MsoNormal">Ahoj,<br>
<br>
zkus se podivat treba sem:<br>
<a href="https://github.com/NibblesLab">https://github.com/NibblesLab</a><br>
<br>
Najdes tam MZ-80C, MZ-80B a dalsi projekty, minimalne v tom najdes vsechny<br>
svaby, cos pozadoval, jako knihovny.<br>
<br>
Jinak existuje uz mnoho let japonska VHDL emulace MZ700 pro Spartana 3,<br>
ale zatim jsem nasel jenom binarky, zdrojaky asi japonci nepusti.<br>

<p class="MsoNormal">Kluci nemate odkazy na HDL kod (VHDL,Verilog) na soucastky co obsahuje

Sharp? Pro zacatek i8253, i8255 a NE555 a pak i Z80 PIO? <br>
<br>
zvukovy cip je 76489 je napr. <br>

Nasel jsem treba: <br>

<br>
<br>
Jinak existuje zajimavy projekt <br>
<a href="https://github.com/MiSTer-devel/Main_MiSTer/wiki">https://github.com/MiSTer-devel/Main_MiSTer/wiki</a> a tam jsou emulovane
<br>
ruzne pocitace. <br>
<br>
Idealni kdyz by ten kod pro z80 pio dobre emuloval interrupt jak je <br>
popsano v: <br>
<a href="http://smithsonianchips.si.edu/ice/OCR_ScanPE125/PE125(10379-K).pdf">http://smithsonianchips.si.edu/ice/OCR_ScanPE125/PE125(10379-K).pdf</a>

<br>
<br>
U toho NE555 se mi jedna aby emulace se snazila emulovat <br>
nabijeni/vybijeni kondenzatoru u 556-IO3C <br>
<br>
Pak se muzeme pokusit udelat emulator MZ-80K, pak prejit na MZ-80A a <br>
nasledne na MZ700 a casem mozna i na MZ800. <br>
