Hello, all: I got my hands on a PC-based EPROM programmer S/DRAM tester IC tester. There is an ISA add-in card and an external box with ZIF sockets. The only thing that I am missing (doh!) is the software diskette. The board is manufactured by Yih-Lung (Hong Kong), model# YL-23. It has two microcontrollers, both are Motorola 6821. I know that this is a loooong shot, but can anyone point me in any direction to find a replacement disk. Thanks! +============================================+ | Rich Cini/WUGNET | <rcini(a)msn.com> | MCP Windows 95 and Windows Networking, | Charter ClubWin!
