Only two parts matter: a \u003cstrong\u003e27C512 EPROM\u003c\/strong\u003e holding the full Apple-1 ROM image, and a handful of \u003cstrong\u003e74LS TTL chips\u003c\/strong\u003e that quietly remap the address space.\u003c\/p\u003e\u003cp\u003eThe result: the authentic 1976 \u003ccode\u003e\\\u003c\/code\u003e prompt, running on hardware you already own.\u003c\/p\u003e\u003ch2\u003eWhy Was It Made?\u003c\/h2\u003e\u003cp\u003eOriginal Apple-1 computers are scarce and fragile — even bare replicas require 40-year-old parts. By letting the Apple II supply the 6502, RAM, keyboard, and video, the entire \"Apple-1 experience\" is reduced to a single modern EPROM and a few dollars of 74LS glue logic. Every enthusiast gets a rock-solid, affordable way to see the 1976 monitor prompt.\u003c\/p\u003e\u003ch2\u003eWhat Makes It Special?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne-chip wonder:\u003c\/strong\u003e The 27C512 carries Woz Monitor, BASIC, and bank-switch code — no flash utilities or programmers needed after assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZero configuration:\u003c\/strong\u003e No jumpers, no firmware updates, no cassette dongles — SAVE\/LOAD naturally route through the Apple II built-in cassette port\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCycle-true behavior:\u003c\/strong\u003e Exact 256-byte monitor entry points and 4KB BASIC means every vintage type-in listing — from \"Star Trek\" to \"Micro-Chess\" — runs unaltered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDIY transparency:\u003c\/strong\u003e The entire 64KB image is open source — swap the EPROM and boot your own 6502 monitor, diagnostics, or tiny games in the unused upper 32KB\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCompatible with Apple II, Apple II+, and Apple \/\/e\u003c\/li\u003e\n\u003cli\u003e27C512 EPROM — holds complete Apple-1 ROM image\u003c\/li\u003e\n\u003cli\u003e74LS TTL address space remapping — transparent and reliable\u003c\/li\u003e\n\u003cli\u003eWoz Monitor + Apple-1 BASIC included\u003c\/li\u003e\n\u003cli\u003eSAVE\/LOAD via Apple II cassette port\u003c\/li\u003e\n\u003cli\u003eOpen source 64KB ROM image — fully customizable\u003c\/li\u003e\n\u003cli\u003eNo jumpers, no configuration required\u003c\/li\u003e\n\u003cli\u003eStandard Apple II slot card form factor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow It Works\u003c\/h2\u003e\u003cp\u003eWhen inserted into any Apple II peripheral slot and powered on, the 74LS logic remaps the 6502 address space to match the original Apple-1 memory map. The 27C512 EPROM provides the Woz Monitor and BASIC at their original addresses. The Apple II's existing 6502 CPU, RAM, keyboard encoder, and video circuitry do all the work — the card simply tells them to behave like a 1976 Apple-1.\u003c\/p\u003e\u003ch2\u003eCompatible Systems\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eApple II\u003c\/li\u003e\n\u003cli\u003eApple II+\u003c\/li\u003e\n\u003cli\u003eApple \/\/e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Denjhang's Retro Hardware","offers":[{"title":"Default Title","offer_id":46178197897413,"sku":null,"price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/8507\/1813\/files\/04_db2a0098-23c0-4f5b-ab19-166c114af86e.jpg?v=1777994400","url":"https:\/\/denjhang.myshopify.com\/products\/apple-ii-apple-1-emulator-rom-card","provider":"Denjhang's Retro Hardware","version":"1.0","type":"link"}
