Hi,
I don´t know if it possible. But I have a 110-120V power supply. Maybe you want swap?
We probably could, but shipping might be a stumbling block...

Is there an easy conversion back and forth? I have a German 240V 128D in the USA where we mostly use 120VAC.
I have a converter box, but I'd rather convert the power supply if that is easily possible.

I added the WGU serial number series to my site. Please register them so they can be counted. (Legitimate original serials only)
-
This is obviously (by the part number) after the 250425, but curiously BEFORE 250466. Maybe this board was not stable or the new PLA could not be manufactured quickly or cheaply enough (it was not a Commodore chip- I thought it was a Sanyo) so they stuck with the old design for one more iteration?

For some reason on my C64, the output became weak. I don't know what changed with the system, but I changed the 150ohm resistor divider on the Luma to a potentiometer instead of 150/150 and the brightness was back to normal around 75-100/150.
Perhaps a potentiometer here would be good for others. I used a 0-200Ohm.

You are lucky- at least it will still work as a 1541. I have one with the opposite problem... Bottom head dead and top one OK.

Was a sprite multiplexer built in hardware? (Similar to the Nintendo NES with 128 sprites, 8 per line.)
"256 ... Sprites with up to 8 Sprites per line"
It's just another way to describe what VIC-II actually has.

If anyone is interested in one, I have an Nexys 4 DDR with packaging, all materials, and the latest bitstream all set up already.
I never use it. I am in the USA.
PM me and make me an offer I can't refuse!

I would ask what is a 1571-II because I've never seen such a thing, but I assume it's a cost-reduced 1571 that uses the 5710?
-
It may not default to address "8".
Try 10 (or 9, or 11)
-
I like it so far. Very well done.

Display MoreHi Snoopy ,
while we got this Thread now, did you ever had a chance to look into
the unknown ROM dump on Bo Zimmers website ?
I am refering to the file at the bottom of the page.
i've tried it once to unpack it, but since i don't have an Amiga i failed on the strange
.LZH file extension.
Those are 911101 and 910429
do you mean 911001 or 910111
Whatever the common known latest one was before...

This is not a surprise. It's easy to confuse VICE while changing drive types, etc. while it is already running. I end up making many shortcuts with different configurations for testing to avoid this.
Consider that what you are doing is unplugging/plugging in drives while the computers is "ON" which you would never do.

PLA is FAR more likely to fail than the 2114
-
Resocket and recheck all connections. I had a board do something like that and it turned out to be a bad socket connection on the PLA. In my case, memory test on dead test would report random results.
-
Thanks, this does boot, but it's very unstable. When you exit to the menu and hit F5 to reboot, it corrupts the screen and you can't really do anything after that.
Rolled back to June release and it's OK.

On my Nexys4DDR board:
nexys4ddr-widget-20200624.00-HEAD_n-4a8842d+DIRTY boots fine.
However,
nexys4ddr-widget-20200830.21-HEAD_n-4a8842d+DIRTY does not.
I just get some odd trash that looks like it's output from the C65 character generator, but white on black. Is there some other new files or ROM needed now or some other change?
-
I've had it working in VICE before (there are special menu settings for burst mod) but I never could get it to work on a real C64.
It was not as speedy as Jiffy and the loader was not very compatible, so it was not useful.
-
This build works for me, but the newer 30-08-20 bitstream does not. It just has trash output to the screen...
