1.1B STATUS and Project Completion


DEC RL01/RL02 FPGA based Disk-Emulator

The operation of the RL01/RL02 Emulator is best viewed with a VIDEO via YouTube, however, in the first version, based on the DE1-Board.



Development and completion of a PCB board for the RL01/RL02 disk emulator

****** NEW ******
My recommendation:
Version V2.2
Support of .DSK RL-Image files

GitHub
DE10-Nano_UserManual_V2.2


DE10-Nano board Implementation
Complete port of the RL-emulator to a SoC/HPS environment based on the DE10-Nano board. It is the ideal board . For example, a PDP-11 and PDP-8 emulator is also running because of the fast ARM Cortex-A9 CPU … and much more ! A Raspberry Pi 3 can be used as a development system. You can comfortably use the graphical interface from the Raspberry and connect the DE10-Nano board via the network. This is so great because the DE10 Nano board is binary compatible ! For example, I have compiled the PDP-11 and PDP-8 emulators on the Raspberry and the binaries are runable on the DE10-Nano board. More details in DE10-Nano startup folder (README.TXT). The necessary disk-data convert programs are of course also available to convert the emulator format .DEC to .DSK and of course the other way round. The whole project is open source. I only used a standard editor (in my case the notepad ++) and a make file. Details on GitHub. The project is very fexible and this is just the beginning and there is still plenty of room for more additional extensions and applications. I would be very happy about a cooperation.

DE1 Board Implementation
emulates only 1 RL01 disk drive

Our emulator interface also works with this relatively 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 e-mail.



DE0-Nano-SoC Board Implementation
This is the configuration based on the DE0-Nano-SoC board. It will probably be available in early of 2018 in the first version.

The entire project was ported successfully, but unfortunately the DE0-Nano-SoC board is no longer available. As mentioned above, a port to the DE10-Nano board was successfully completed.



In the end, this was my last wire wrap work.
