Re: What GSE-Reactive Really Needs to Make

VGA would be nice, but I wonder if s-video would be good enough for
clear 80 column text.

As for keyboards, there seems to be no shortage of ADB keyboards still
available. I think you can even get new ones.  So the GS is covered.
GSE already sells replacement Apple IIe keyboards.

USB might be nice for key drives, but the various CFFA cards have that
functionality covered too. The two widgets I need for personal projects
are;

First, an adapter to get from the oddball 28 pin 128 k PROM on a ROM 0
GS to either a standard 32 pin eprom or a pair of 64k eproms (I have
lots of those) and I assume an inverter to choose between the chips.
Then I can upgrade it.

Second, a clone of the IO32 card Applied Engineering once made. I
probably can wire-wrap a 6821 and get it to work (I have lots of them
too), but having two of them and some easy to use ampersand routines to
run the things would be nice.

 Analog Input I have running using the voltage input box from the
better mousetrap book (www.vernier.com) which I modified to use the
cassette input port on a IIe. The Chaos book from vernier shows how to
use a serial ADC chip, and a DAC chip from the annunciators, but there
are only four of them, after all. And only the three or four
pushbuttons for the digital inputs.

While I'm wishing, a Mac version of Ciderpress would be nice too. :-)
