I had one of these for a couple of years. 8 bit card, 16 pin. External cd-rom that looked like a audio component with the phillips branding. Worked in a friends XT! (at least it did...guy broke everything i gave him last i knew)

I've got the drivers for it somewhere if anyone's interested.

He doesn't have a pressure washer and a YouTube channel by any chance, does he?

:lol:

YouTube channel? Yes

Pressure washer? Oh, no. He's quite intelligent enough to understand certain toys can cause grievous bodily injury.

Actually, i was a bit crude with my wording. Its 1/2 a matter of circumstance (stored said XT/AT machine in a basement before he realized how badly humid it got down there) When i decided to try and revive it the traces were swollen so badly it looked like spray-on hammered-look paint. I had to sand and paint the metal of the case to prevent further rust/rot.

Though I still can't get him to invest in a decent online ups in a house with 1/2 the wiring shot... :hammer:

...and there's a ti-99 with the expansion chassis down there last i knew...

Ouch.

Fix the wiring, don't hide the problem. Wiring in that state really is a fire hazard. If it were me and I couldn't afford to inspect and replace and bad wiring and connections, I'd at least be inclined to install new arc-fault breakers, and derate them considerably. It would at least certainly be worthwhile to listen for arcs with an untuned AM radio receiver.

I realize this is an old post - but I could really use the drivers for the CM-205 controller/CD-ROM - I've lost my floppy - can't find online - thanks!
