Perhaps worth noting is that the designer of the original WebTV interface was the late Keith Ohlfs, who also designed NeXTSTEP's windows and icons circa 1987.

I thought it would be some basic stamped metal or something. Looks like it's held on with the screws from VGA and Serial. Yeah, it seems incredibly well-done. (Probably not FCC-compliant because it lacks shielding... :) ) The whole board is well-finished and clean, and I really appreciate the …

Not stereo, unfortunately, but the Ultimedia line of IBM PS/2's circa 1992 had a well-amplified, full-range speaker as part of the case, complete with volume control knob and 1/4" (!) headphone and microphone jacks. While normally coupled to an oddball DSP-based MWAVE card, which was nearly useless …

Great work! The next level would be to buy an IBM PS/2 Speech Adapter, 3D-print the (never-shipped) internal mounting bracket for the front panel of a Model 30, and re-wire it to use the 'official' speaker. 😀

The floppy drive may well fail to work unless you have a working CMOS battery installed; these machines lose track of their drive configuration without it.

Not sure what made me try, but the IMFC fits (and works) inside a PS/2 Model 25: https://farm2.staticflickr.com/1465/25906025645_06a3b80658_c.jpg And yes, the machine can close too... The top slot is, unbelievably enough, a full 13" long. As you rotate the bottom closed, the end of the IMFC goes all …

Re: those later Sierra SCI games; one of the frustrating things was that they put up a full-color Windows title bar at the very top of the screen, even when the game was in full-screen mode. This was pretty distracting in darker scenes -- really took away from the mood. It's also interesting, in …

Those of us (un)lucky enough to have collected an Ultimedia PS/2 know that the audio features of this machine are a mix of good and bad: great front-panel amplified speaker with volume control and headphone/mic jacks, coupled to a terminally-unsupported audio card ( M-ACPA or AudioVation , choose …

The issue with these is you need specialized tools to release plastic catches inside the monitor, after the screws are removed. I've heard you can fudge it with it with slot covers, but would be wary of sticking anything conductive into part of a monitor that I can't see. If you do find diagrams or …
