Three questions about the Altair 8800 kit

[sje]

Thank you for your replies.

If the SuperAltair board were produced, then it would remove the need for many other kinds of boards. I see to recall from a decade ago that there was a similarly specified board from Harte Technologies, an effort connected to the IMSAI revival. Is there any connection to the SuperAltair board? Could the Harte board be put into production?

One difficulty with the SuperAltair or similar board is that things in peripheral land have changed a bit over the past few years:

1) New PS/2 keyboards are hard to find.

2) New serial/USB adapters are becoming hard to find.

3) The days of VGA are numbered and perhaps the same can be said of DVI. But HMDI output enjoys the leverage of many, many low cost consumer televisions with 1920x1080 input.
