Hello, a MINC system is up and running , but the VT105 is completely defective, water damage. I'm looking for a VT105 terminal emulator to be able to run the MINC-Basic. Does anyone have any hints? Thanks in advance.

I am currently trying to develop a RK05 disk emulator. It is an addition to my existing projects, the RL01/RL02 and MFM disk emulator, and will be also based on the DE10-Nano FPGA board. The firmware and the associated C program is almost ready. Everything is based on Quartus version 22.1...

In the sad and frustrating Corona times, however, there is time to expand some projects. My RL01/RL02 emulator supports a combination of real and emulated RL disk drives but always a DEC computer like a PDP-11 still is necessary to move data around. A new program, called clonerl can directly...

I just wanted to get in touch with an update. All information on GitHub https://github.com/pdp11gy/SoC-HPS-based-RL-disk-emulator and on my homepage. With this innovation, it is now possible to run my RL-emulator and all SIMH emulators on a single board, in my case it is the DE10-Nano. A...

Hi all, a short announcement: My RL01 / RL02 disk emulator is now available with a PCB board and support for the MAX10/DE10-Lite, BeMicro CV, DE0-Nano and DE1 board. A picture and a description in the appendix. All further information on my homepage, chapter 1.1B with all necessary downloads...

Hi All, referring to my last post concerning RL01/RL02 and MFM - disk emulator based on BeMicro CV board: http://www.vcfed.org/forum/showthread.php?48099-RL01-RL02-and-MFM-disk-simulator-based-on-BeMicro-CV-board&p=372033&highlight=#post372033 Here is the update with good and primary bad news...

Hi All, It's been some time, but now there are some good news. There were many problems to solve in the BeMicro-CV FPGA Development Kit. The main problem with a specific series of Cyclone-V cips was solved by a Cyclone-V FPLL Patch from ALtera. Many other problems I could solve, like EPCS reset...

regarding to my last thread "Improved RL01/RL02 disk simulator available", November 17th, 2013, I would like to discuss the problems which arose in the development of the ST506/412 simulator. In the appendix you will find two documents, the prototype of my interface and the C source code of the...

Hello, the new Version V 3.04 is now available via my homepage with new features: Speed improvement. DPR (Dual Ported Ram ) is now included in QSYS. Result: A memcpy is replacing the previously used PIO based controlled I/O. Offline mode will now construct Cylinder 0+1 and the bad sector file in...

Hallo, I have a good new message. The RL02/RL01 disk drive simulator based on the DE0-Nano board is up and running. This implementation provides full flash support and full FAT32 SD-Card support. In other words, we will be now be able to share all RL01/Rl02 based software worldwide. I would be...

Hello, during the design time of my new project, ST-506/412 disk simulator, the RD51 in my micro-PDP was going defective. I am still able to boot from the Rx50, but the RD51 does not respond anymore ( RQDX-1 controller). Error: ERROR UNIT DU0 ERR 14 DRIVE ERROR WISH TO REBOOT [Y,(N)]? The RD51...

Hello, my news: The FPGA based RL01/Rl02 simulator is up and runnig. More detailed information can be found on my homepage, www.pdp11gy.com Hard to believe but also funny, I have a bootable SD-Card running RT-11 and/or RSX-11 on it. Many thanks to you for all the informations you have provided...

Hello @ all Concerning my RL02(1) Simulator project, I am hanging araound again because I have no idea how I can reconstruct/simulate the bad sector file based on a SD card in my project. No exact upgrade info is available, only some notes in the RL02 technical manual on page 49, figure 2-9...

I was getting involved by the computer museum in Munich to restore and repair a PDP-11/40 with attached 2 x RK05 and a papertape reader/punch. It was getting started to remove the much dust and all the dust-filters must be replaced with standard parts From a local like DIY shop. That's very...

I have a relatively simple ask there. I must use the terminal emulator programs hyperterm and/or teraterm because my Vt100 is faulty. But I am not able to save and exit from the ked/kex RT-11 editor programs because I don't know the key/escape sequence on a standard PC Keyboard. ( I know...

Hello, enclosed, please find a picture which shows 2 Q-Bus modules. I have got these modules from the Computer-Museum-Munich but I am not able to identify these 2 Q-BUS modules The module on the left was designed by "QUALOGY" , 800103-02 REV A .The module on the right looks like a special...

.... a spare RLV-11/12 still needed. In view of the very sad events in Japan, everything gets relative.... Hello, concerning my post October 12th, 2010, first of all, the MFM decoder for the RL02 with clock and data recovery is ready, up and running and is available via my homepage, chapter...

Hi all, I am running in a unfortunates situation concerning my RL02-simulator project. My RLV-12 Q-Bus controller board is more and more temporary dead , meens not accessable via console mode.... increasing tendensy ! Replacing the DC0ß05 chips did not solve this problem. My project is now...

Hello, my project , DEC-RL02 disk simulator is going complicated. If you want , you can watch the status on my hompage: http://www.pdp11gy.com/ . Not all tranlated in English but section 1.5 provides a good overview and a lot of pictures give you a good impression. Complete translation in...

Hello @ all, concerning my Thread, 31-JUL-09 a new problem did come up. Background: I got a RL02 , micro-PDP-11, RLV-12 controller from the friendly people at "Computer museum München". I decided to use to use an ARM-7(lpc-p2148) microcontroller instead a PIC processor. I designed my own...
