Source: Post by Bob Bottomley on comp.sys.palmtopsIt looks the the Goldstar Handy PDA will *not* be GEOS-based. Here is what I found in EE Times Interactive, November 20, 1995; Issue 875, page 1:
LG (formerly Lucky Goldstar) will launch three PDA-class products next year, including one it displayed at Comdex called the Handy PDA. Basically a half-pound flip phone with a touch-sensitive screen, Handy was shown in an analog AMPS version with a 320- x 200-pixel electroluminescent backlit screen and a pen interface for dialing and accessing a small suite of personal-information manager utilities.
The analog smart phone will be sold in Korea starting in mid-1996 and will debut in the United States at the end of that year. Based on a proprietary X86-style processor and homegrown operating system, Handy will support paging functions and offer a serial port and connectivity to Windows 95-based desktops.
