Features
The Hard Disk 20 (or HD20, as it was known colloquially) contained a 20 MB 3.5' Rodimehard disk which provided over 50 times the data storage of the stock 400 kB disk drive. At the time when the average file size was around 10-20 kB and due to the vast number of those files the HD 20 could contain, Apple's original Macintosh File System, which did not allow for directories, would have made organizing those files unwieldy. Therefore, Apple introduced it with a new System and Finder update which included the brand new Hierarchical File System allowing the user to better organize files on such a large volume. As a result, only the Macintosh 512K could access it; the original Macintosh 128K did not have enough RAM to load the new file system. In fact, even for the Macintosh 512K to use the drive, it required an additional file in the System Folder on a special startup disk which added additional code into memory during startup. An ingenious startup routine also allowed the Mac to check for the presence of a System file on the Hard Disk, switch over to it and eject the startup disk. Unfortunately, the HD 20 could not be used as a startup disk directly without first loading the code from the floppy disk drive. With the release of the Macintosh Plus and the Macintosh 512Ke, both containing the upgraded 128 kB ROM which contained the additional code, the HD 20 could finally be used alone as a startup disk.

While other hard drives were available on the market, Apple's HD 20 was generally preferred mainly because Apple broke their own development rules when they offered it. Originally the Macintosh was designed with two serial ports which were to meet all the expansion needs of the user. It also included a dedicated floppy disk port for one external floppy disk. Most of the hard drives which were available on the market used the slower serial port to transfer data per Apple's specifications. Apple instead engineered the HD 20 to use the faster floppy disk port, enabling the user to daisy-chain an external floppy disk drive as well as an additional HD 20. With few exceptions, this along with complete compatibility with the new Hierarchical File System, gave Apple an instant edge over the competition. In addition, the HD 20 had a convenient 'zero-footprint' design which fit precisely underneath the Macintosh, merely elevating it 3 inches, but otherwise taking up no more desk-space.[4]

Sep 15, 2018 This simple mod adds a new unique hat to the game. The Battered Cowboy Hat. Description: -The Rawhide Cowboy Hat has always been my favorite hat in the game. Although, recently I have grown tiered of it's lighter colour. So I've decided to make a darker and more worn version of it to fit more with a cowboy character. Mar 28, 2015 This mod adds eight new hats drawn from cowboy tropes, other cowboy-related media and some of my own ideas. Most use vanilla meshes and one uses Daniel's hat from Honest Hearts (DLC required), and two use one of dragbody's meshes from Courier's Cache. I had a lot of fun making them so chances are I'll be adding more.
