#ACCELERATOR/A1000-PROB.
2 messages in this thread
Hi Everbody,
I have a 1000 with a toolbox,8UP! card and a Kronos Autoboot/Quantum
105 meg system.No Problems.
I just bought a Processor Accelerator with a 1.3 ROM installed running
at 14 MHZ(forced).The machine won't Auto Boot,nor will it ask for a
Workbench Disk when the 8UP! is in any of the slots.
It worked before.Any ideas why it won't now.I didn't change anything in
the Tool Box,at first.
Thanks
Dennis
Hi Dennis
I am surprised you got all that stuff to work in the first place with
out doing any mods. I have found the Expansion box to be very noisy.
I am currently Running an A1000 with a Lucas/Frances(4 meg) with the
Phoenix box with power supply. In the Phoenix box I have a 2058 ram card(2
meg) and on the end I have an RSI Wedge controller with 80 meg and 30 meg
CDC wren drives attached.
I originally had a lot of trouble with gurus of the 0003 and 0004
variety and non booting etc. and after talking to the Phoenix support
people they suggested cutting all address & data lines and several of the
control lines as they come into the box and then add a 10 ohm resistor in
series. This helps suppress echoing and noise and I believe is what is done
on the Bus of the A2000. I also have done the Pal ground mod as well as run
an extra ground from the Kick Daughter board down to the expansion
connector ground plane.
I have done all this and find my system to be pretty stable however I
recently tried to get a 2090A board to work but found it to be quite
flakey, apparently it loads the bus quite badly so I have given up for now.
I am waiting for my rejuvenator to come and we shall see how it changes
the bus chacteristics (faster Pals and better loading) may give better
results with addons. Good Luck
