Here's some IIGS porn for you. So far, my development system has 5MB of expansion RAM, an MDIDeas SuperSonic stereo sound card, a Video Overlay Card, an Apple SCSI controller, and an unmodified Transwarp GS. Yes, it does boot, so far. I heard a rumor that a PC Transporter and CompactFlash adapter card were on the way, and maybe even an Uthernet card. Where will they all fit? Won't the power supply blow up? Stay tuned.
