Subj : dell optiplex gtm 5133 ... dos 6.2 cirrus logic modem md3450d To : ALL From : Grant Weasner Date : Sun Jan 22 2017 21:08:43 Hi all, I'm building a reto ms-dos 6.22 system that will be used in support of a retro bbs. I just got the hardware and it has an ISA Cirrus Logic 16bit Modem with the CL-MD4450-c-SC-B chip set. Does anyone here have that modem and use it in DOS or a modem like it. I can't seem to find drivers on the net for it. --- Mystic BBS v1.12 A31 (Windows) * Origin: Agency BBS | telnet://agency.bbs.geek.nz (3:770/100) .
