Co., Balto., Md. Lines: 22 Would like to locate someone who has used the Electronic Control Technology Inc. (ETC) s-100 motherboards with IEEE standard boards. I have a MB-20 motherboard and 30 Amp power supply that I have been trying to use with Godbout boards. The boards (disk1, interfacer3, 8085/8088 cpu, and ram 17) are currently running in a TEI box. I have checked the MB-20 for shorts, grounds and continuity and every- thing looks great. The one big difference I noticed is the type of bus termination used. The TEI has a termination on each bus line while the MB-20 does'nt. I find it hard to believe the MB-20 is suf- fering from noise. A while back I used the board in an IMSAI boxs without any termination at all. Any ideas? -- ====================================================================== signed: Rod Hart (wa3mez) Chesapeake & Potomac Tel. Co. Bell Atlantic Inc.
