c-programs can be edited or modified via
without problems. However, the firmware/verilog source
are missing. We are happy to provide these programs by e-mail. We
just want to know who gets these programs and how the plans are
for using all these firmware sources. Cooperation is really
important to us!

up to 4 RL01 or RL02 disk drives, sorry,
not available at the moment ?? (MAY 2017)
interface also works with this
old DE1 board but there are some limitations due to the only 8MB
SDRAM memory: - Only support of one RL01 disk drive. RL02 support
not possible. - No FAT32 support for the SD-Card and incompatible
file format. For
further questions about this DE1 configuration, please send an
is the configuration based on the DE0-Nano-SoC board. It will
probably be available in early of 2018 in the first version.
It is the ideal board because it can also be
used for other purposes such as PDP-11 and PDP-8 emulators.
However, a lot of issues must be new developed.
A NIOS II CPU with the existing C-code is very difficult to
implement here, so everything has to be ported to the ARM
Cortex-A9 CPU environment. If someone has already experience with
this environment I would be glad about a contact very much.
Perhaps it is also an interesting challenge for
a student? Cooperation is very important.
the end, this was my last wire wrap work.
