Won't work, simply because the floppy port on the GS doesn't have the firmware to support the HD20, while the early Macs did. But there are many better hard drive options for a GS, anyway.

Here's some gleanings from my database of a2gs inf. Ibelieve it was supplied by Supertimer on the csa2 newsgroup. There are two things you need to do to get the IIGS usable. First, get a hard drive for it. http://www.allelec.com/ Alltech Electronics sells an internal hard drive for the IIGS that is a hard drive on a card. No extra controller needed. It is an IDE controller plus notebook mechanism. It costs $59. For that price, you also get the most modern Apple IIGS System Software, GS/OS (System 6.0.1), which is normally on six separate floppy disks (a hard drive is needed to get the most out of it). You also get tons of freewares and sharewares. The hard drive is called the Focus hard drive card. Look for it on the Alltech site. The other thing is memory. Alltech (see above for web site) also sells the Sirius RAM card. They are revising their web site, so this product may not yet be on there, but just call them and ask. It is a 0-8MB memory card that can be expanded in 1MB increments using 1MB 30 pin SIMMs. I'm sure you have an old 386 lying around that you can gut. Only the IIGS can run a graphical OS somewhat similar to MacOS. The IIGS' OS can, with the proper software, generate printed pages on high resolution ink-jet printers and laser printers with TrueType fonts, an Apple (same as Mac) style GUI, and the use of the same keyboards and mice as the Mac (in fact, ADB was first used in the IIGS before being used on Macs...pre-GS Macs used "telephone" style keyboard cables). The IIGS has built in support for 15Khz analog RGB color. The IIGS itself has a 4096 color palette and is capable of theoretically throwing up to 3200 of those on screen at once. The monitor the IIGS uses will also work on the Amiga and Atari ST and their monitors will work on the IIGS. ------------------------------------------------------- some URLS http://www.allelec.com/ http://www.sequential.com/ Sequential Systems. http://ground.ecn.uiowa.edu/ I believe the A2 FAQ by Rubywand and a bunch of other stuff is still on this site or you can find it regularly on the csa2 n-g. There used to be older FAQ by one Nathan Mates a notorious csa2 flamer who, in a snit, removed it from circulation. If you contact me off-list I MIGHT be able to tell you what was in it. Since I've had an A-gs monitor for years and by the Law of Affinity knew that a GS would eventually find it's way to me (thanks Rich) I've kept this info and even the GS manual.
