   Yes, it is out; I have one in my 130XE. As it is, I don't think it was
worth it. The main reason is that the clock speed is still stuck at 1.79Mhz.
I haven't kept up with things in the last year or so, but last I heard
DataQue was looking into the possibility of introducing a new video board
for the thing. The main problem with upping the clock speed is that it
tends to freak out the ANTIC chip. With a new video board, it may be possible
to disable ANTIC & switch to a higher speed. I have heard rumors of 65816
chips that will crank up to 20Mhz, but I believe the Turbo-816 65816 is
rated at 5Mhz (Though I understand it may manage, say, 8Mhz.) But then the
RAM will slow things down. Extended static RAM cards are available, and will
support (I believe) up to 2Meg of SRAM.
