Rare Apple II Clone 6502 Computer Deep Dive - MicroSCI HAVAC

Dive into the fascinating world of rare Apple II clones as we explore the MicroSCI HAVAC (Home Academic Very Affordable Computer), a compact 6502-based Apple II-compatible system from the early 1980s. In this video, we: Examine the HAVAC's rear ports and test compatibility with the Floppy Emu Disk Emulator (Apple II, Macintosh, and Lisa). Open the case to inspect the internal floppy drive, power supply, keyboard connector, joystick port, and motherboard. Take a closer look at the socketed chips, two DIP switch blocks, and four EEPROMs that deserve archiving. Compare the HAVAC’s keyboard to the Apple IIe keyboard for similarities and differences. Load and play classic Apple II games like Oregon Trail, Dino Eggs, Lemonade Stand, and Hard Hat Mack using the Floppy Emu. Experience some true retro enthusiast excitement when a RIFA capacitor smokes out and evaluate the aftermath.
