Greetings, Attached is a disassembly of the Macintosh SE FDHD ROM from within vMac by the FDisasm application using the configuration files for the Macintosh SE. I made GitHub repository for updating the listing and commenting on the ROM. https://github.com/Frimples/MacSE_FDHD_ROM The source for the ROM is in the repository.

In the February 1987 issue of the A+ Magazine, there was a cover article about upgrading to the IIGS from the IIe with the board swap. Whether it was cost-effective for schools was also discussed in another article. The searchable PDF file of those articles is attached herein for download. Enjoy! :)

Paul Hagstrom from the Apple II Enthusiasts Facebook group very kindly provided me with this PDF, which I uploaded to Archive.org for preservation and subsequently linked here on TinkerDifferent. It showcases the complete Apple product line being sold as of the summer of 1993. My main interest in seeking out various versions of "The Apple Catalog" was to find Apple IIe Card advertisements from back in the day, but I must say that this catalog is jam packed with many interesting computers...

UPDATE! :) Gary Rice generously released the Black & Bleu - The Ultimate Mac Error Codes Utility on Macintosh Garden. This is an excellent resource for making sense of the Sad Mac codes, more than what is listed below. Apple's overview below is a good guide to introducing yourself and getting basic ideas about the Sad Mac codes. Then, the Black & Bleu program for 68k and PPC Macs running System 7.0.1 through 9.2.2, as well as OS X 10.2, can provide a more detailed list and details of the...

SMD devices are, by their very nature, too small to carry conventional semiconductor type numbers. Instead, a somewhat arbitrary coding system has grown up, where the device package carries a simple two- or three-character ID code. Identifying the manufacturers' type number of an SMD device from the package code can be a difficult task, involving combing through many different databooks. This HTML book is designed to provide an easy means of device identification. It lists well over 3,400...

The following is a compilation of German material translated by Google with little to no effort in trying to manually clean it up. The thread - The PAK68/3 Accelerator - [German] contains the original text and discussion. The creator Holger Zimmerman, aka pakman, is still very active to this day and always willing to help out in getting the PAK68/3 working for users. This article contains the following: Introduction to the PAK68/3 (translated from http://www.wrsonline.de/pak3.html)...

This is pulled together from Gamba's mac pages, and reformatted for easier readability.

The goal for this resource article is to document identification and reference information on the various L2 cache modules for Power Macintoshes and clones. While at a quick glance many of these L2 cache DIMMs look similar there are different pin (edge connector) groupings that key the 160 pin connector for different types of PPC Macs. This is a work in progress, if you have any info to add or can check, take pictures of the modules in your Macs and let me know it would be greatly...
