Hi Nigel,
I read in Commodore Free that I
suggested that the 1541 Ultimate Plus
would be a good SuperCPU replacement.
I never actually said this; what I
suggested was that with a battery
back-up function (which I think is
intended on a future revision), the
device could be a RAMLink replacement
at some point in the future.In
emulation, someone has already hacked
Wheels to recognize a 17xx Ram
Expansion Unit up to 8 megabytes, and
theoretically up to 16Mb. Okay, so
this hasn't been done in the real
world as far as I know, but the 1541U+
as far as I can gather basically has
the same function as a 1750 REU (for
instance), but up to 16Mb. A RAMLink
is 16Mb, so all that is needed
is either a power source to keep the
RAM in a solid state, and some sort of
DOS interface to read the contents of
the RAM (you'll note that the RAMLink
can do this already as you can plug a
1750 REU or clone into the RAMPort,
which can be either 'normal' access
via JiffyDOS, or 'direct' access as it
was intended to be used, which is only
possible because the memory is kept
constant as long as it remains plugged
into the RAMPort and the RAMLink isn't
unplugged).
Even without accessing the RAM like a
drive, you can skip RAMDisk formatting'
on Wheels, and have a RAM disk on your
desktop. This keeps the memory ON even
after a soft reset, but obviously
switching the computer off will clear
it. So, keeping power to the 1541U+
even after switching off the computer
should also keep the memory intact,
meaning that you can have all of your
GEOS apps in RAM for super-fast access.
The 1541U+ is going to be some kick-ass
device, that is for sure! As for a
SuperCPU clone... well, who knows what
the future will hold ;-)
Sorry for the rant!
Regards,
Shaun.

Sir:
Sorry to trouble you. In your issue
#16, under news, there was an entry
concerning Loadstar. I was interested
in purchasing some Loadstars but
cannot bring up the website. Does
anyone know if this website is no
longer active or if Dave Moorman is
out of business? Sorry I don't do the
forums so I don't know what is
happening with C64 stuff. Thank you
for your informative Commodore
Free magazine.
