I bought this because it runs GEOS and was curious on the implementation. It runs GEOS over MS-DOS. It runs quite smoothly. It came with all the manuals, disks, etc. I ordered a battery for it. Shipping from Asia as far as I can make out. Keeping fingers crossed. It’s very quiet. Keyboard feel is terrific. You’ll see Apple GEOS entries throughout this blog; geoPublish, geoWrite, geoCalc and more.
