Ok, maybe it's a bum deal, I don't know, but they were cheap...
I recently expanded my modem collection by buying two Hayes SM1200 OEM modem
boards at Halted, here in Sunnyvale, CA. They were selling them for $12.00
(yes, that's twelve!), so I couldn't resist. I bought one, and zapped the
Z8 chip. So, I bought another. These OEM modems are external, have no
switches, LED's or box. It's just a PC board, with about 12 IC's, and some
resistors, etc. The board does not generate RS-232 levels, so a 1488/89 type
convertor circuit is necessary. After wiring up the whole rats-nest, I tried
talking to the thing, and hey! It responds. I can examine all the S-registers,
and set them, etc. However, when I try to dial out, nada. If I listen on the
line, I can hear the faint touch-tones. Ma bell can't hear them, however,
because the dial-tone never goes away. The first one I tried had this problem,
so I brought it back and exchanged it. The next one does too. My question?
Has anyone heard of these things?? Or know anything about them?? I'd really
like to get one going, for the hell of it. It seems to me, that two such
boards couldn't have the *exact* problem, so maybe I'm screwing up in some
way. Any help would be appreciated. OBTW; Halted deals in used & junk
electronic hardware (anyone want an RK05 for $125???). Thanks...
