A DIY enthusiast has developed a portable laptop powered by the 6502 CPU, a processor that served as the backbone for many iconic 1980s home computers. The project, which the author describes as a striking design, integrates modern components with vintage architecture. The hardware configuration includes a 65C02 processor running at 10MHz, 46KB of user RAM, and a 10.1-inch screen capable of displaying 1024x600 resolution with 256 colors. To bridge the gap between the 1980s and today, the laptop includes a WiFi modem and a nanoSwinSID for sound, alongside a CompactFlash card for storage.
The technical contrast between the laptop's internal memory and its external storage is a point of significant discussion. While the 6502 processor is limited in its addressable memory, the use of a CompactFlash card provides a massive storage overhead. Commenters on Hacker News noted that a 1GB card can hold the contents of the laptop's 48KB RAM over 21,000 times. To put this in perspective, one commenter pointed out that if a modern 8GB laptop had an equivalent storage ratio, it would require a disk capacity of approximately 174TB.
Beyond the hardware specs, the project explores the practical limits of vintage computing. The device runs EhBASIC 22p2 with custom extensions and eWOZMON. Some observers noted that while the 6502 is a low-power processor, the project's ability to maintain a modern form factor with a large 7400mAh battery and USB-PD recharging is a notable engineering feat. The discussion also touched on the philosophy of such builds, with some suggesting that much of modern computing power is spent on GUI and rendering stacks, whereas the 6502 remains capable of handling many basic workloads that have not fundamentally changed in profile over the decades.
