Very early Apple II computer in its extremely rare original ventless case, carrying a scarce Rev. 0 logic board (green), featuring the "Apple Computer, Inc." logo with a copyright date of 1977, hand numbered in the corner in black felt tip: "1-462." No revision number is printed within the 6502 socket, which is populated with a Synertek M0S 6502 microprocessor, marked with date code "7729D." The board is fully populated in a stock configuration, with an additional "Sup 'R' Mod. II Ch. 33 TV Interface Unit" installed inside and some modifications made in the prototyping area. The power supply and keyboard are original. The bottom bears an "Apple Computer Inc." label, identifying it as "Serial No. A2S1-0195." Untested and in very good to fine cosmetic condition, with the slot prongs on the rear slightly warped, one of the black tabs used to secure the cover missing, and a "ComputerLand" retailer's label affixed to the right side. Accompanied by an uncommon brown Apple carrying bag with the Apple logo on the front, and a period Sanyo VM4209 CRT video monitor manufactured in March 1979—the preferred monitor for use with Apple-1 and Apple II computers, as seen in early Apple advertisements.
The early success of the Apple-1 in 1976 paved the way for the introduction of the Apple II in the spring of 1977. In Apple’s 1980 IPO prospectus, the company described its progress: ‘In April 1977 the Company introduced the Apple II computer mainframe which was similar to the Apple I but incorporated additional circuitry and a keyboard, and was packaged in a plastic housing.’ In other words, the Apple II built upon the Apple-1 to become an even more capable, more consumer-ready machine.
Apple II computers initially came in this ventless case, but they experienced frequent overheating issues: this often led to various custom modifications to the original cases, with users cutting their own ventilation holes or wiring DIY fans into the housing. Within months, Apple introduced a vented case that solved the overheating problem and offered existing users a free replacement. As most early Apple II users took advantage of the upgrade or vented their cases themselves, unmodified ventless Apple II computers are very rare.
