The blog post details the author's journey in reverse-engineering the System ROM (SROM) of their AlphaStation 255/300. Driven by curiosity and the desire to understand the boot process, they meticulously documented the SROM's contents, including memory maps, initialization routines, and interactions with various hardware components. This involved using a logic analyzer to capture bus activity and painstakingly decoding the assembly code. Ultimately, they were able to create a disassembled listing of the SROM and gain a deep understanding of its functionality, including the system's initial boot sequence and setup of key hardware like the interrupt controller and memory controller. This effort allows for greater understanding and potential modification of the early boot process on this vintage Alpha system.
The Amiga 600, initially met with disappointment due to its perceived regression from the Amiga 500 Plus – lacking a numeric keypad, expansion options, and a real floppy drive – has become a retro favorite. Its compact size, built-in PCMCIA slot (offering exciting expansion possibilities despite initial limitations), and affordability contributed to its eventual popularity. While initially overshadowed by the more powerful Amiga 1200, the A600's simplicity and ease of use, along with a growing community developing software and hardware enhancements, solidified its place as a beloved and accessible entry point into the Amiga world. Its small footprint also makes it a convenient and portable retro gaming option today.
Hacker News users discussed the Amiga 600's initial lukewarm reception and its current retro appeal. Several commenters pointed to its awkward positioning in the Amiga lineup, being more expensive yet less expandable than the Amiga 500 while also lacking the power of the Amiga 1200. Some felt its small size was a drawback, making upgrades difficult. However, others appreciated its compact form factor and built-in floppy drive. The lack of a numeric keypad was also a frequent complaint. The overall sentiment reflected a re-evaluation of the Amiga 600, acknowledging its initial flaws while also recognizing its strengths as a compact and affordable entry point into the Amiga ecosystem for modern retro enthusiasts. The discussion also touched upon the broader context of Commodore's mismanagement and the Amiga's ultimate demise.
The author details their journey restoring and upgrading a beloved Commodore Amiga 1000. Driven by nostalgia and a desire for a "perfect" retro computing experience, they meticulously cleaned the vintage machine, recapped the motherboard to address aging components, and expanded its capabilities with modern hardware like a CompactFlash hard drive and a Rejuvenator accelerator board. This allowed them to run the original AmigaOS while enjoying significantly improved speed and storage capacity. The process, while challenging at times, ultimately fulfilled their goal of experiencing the Amiga 1000 as they had always imagined it.
HN users generally enjoyed the blog post about restoring and upgrading an Amiga 1000. Several praised the author's writing style, finding it engaging and nostalgic. Some shared their own Amiga memories and experiences, highlighting the machine's significance in their personal computing journeys. A few commenters discussed technical aspects of the Amiga and its upgrades, including the Vampire accelerator and the challenges of working with older hardware. One user lamented the "sad ending" of Commodore, while others reflected on the evolution of computing and the Amiga's place within it. The overall sentiment was positive, with many appreciating the author's passion for retrocomputing and the detailed account of their restoration project.
