I'm selling an Apple IIgs ROM1 Woz Edition with an Apple Hi-Speed SCSI card (most compatible SCSI card), a rare Apple Video Overlay card (can overlay video input into the IIgs monitor/video output), and a rare Applied Engineering GS-RAM III memory card. The tiny memory card uses 512KB ZIF memory chips, currently filled with 3MB of memory (maximum of 4MB).
Tested with my external SCSI hard drive and standard peripherals (not included):
