It does support this, but it's experimental, and I haven't tried it yet, but am keen to. Here's the documentation

It's awesome to hear those images are working ! I'm really glad you're working on getting a scratch install going - as I was really curious if that was possible. I'm not very knowledgeable about MFM hard disks (was an apple guy back in the day, so never used them when they were popular)...

Ok, thanks for the correction - I didn't even think to check if the commands were on the path. Thanks very much for creating the emulator, it makes such a huge difference in being able to save these old machines!

I've been working on my IBM System/36 lately, and one of the projects I had for myself was upgrading the version of SSP (from V4 to V5). Before I did this, I really wanted to back up the hard disks in my machine, just in case anything went wrong. Based on poking around the internet, I had...

With the help of a new, and very generous, friend from the forum here, I was able to replace my bad floppy drive, and the new floppy works great. The new floppy drive is a YE Data YD-380 Type 1718. Thank you very much (you know who you are :) ! I was able to upgrade my 5364 from V4 to V5...

I recently completed some long overdue upgrades to my Micro-PDP11/23, and thought I would share them here. I got this machine about 20 years ago from the building manager of a building I used to work in. She was happy to have someone get it out of her office, and I gladly took it! It had...

I just set this up myself... If you go through the demo program, you go through the 'd' option, then 'en DL11' - and that's it... If you add this to one of the .cmd files then you can enable the DL11 along with something like 'm i' for memory. In autostart.sh, I reused the memory option...

It's working! One issue that was tripping me up was the default vector address for the DEQNA in the build script was 400, but the correct address from the manual is 120. After correcting that, and rebuilding the kernel, qe0 was working. My PDP11/23 is now a stealth 11/73, and talks to my...

yep, it is. Thanks for that - I didn't understand the positioning of the cards very well. I'll correct it...

I figured out my problem with the RQDX3 - turns out the problem was ME... when I tested the configuration above, I had failed to put the SD card back in the zuluscsi. DOH... Now, in the config above, with the SD card in, it boots just fine... Now on to getting the DELQA in DEQNA Lock...

I added back the DELQA, and the system still boots up fine. I then added the RQDX3, and the system fails to boot, just waits indefinitely, and no lights come on on the UC07, so I think the RQDX3 is the culprit. I'm going to double check the switch settings and jumpers. Since all I'm using...

That worked! I removed the RQDX3, moved the UC07 in it's place (also removed the DELQA I forgot to mention was in there too), Jumpers 1-8 on KDJ11-A set, and it BOOTED!!!! This is so awesome - I'm going to go back to my original goal of getting the DELQA working. Will rebuild a new...

hmmm I may have got the address mixed up in my mind, and not double checked... ok I'll try again. I'll remove the RQDX3... also forgot to mention, I have the QBone TTYS2 (really called S1 - the manual appears to be wrong) emulating a DL11, and that seems to work, at least with ODT...

Here's the setup I tested: Jumpers on the KDJ11-A were 1-8 IN, 9 Out I also tried 1-7 IN, 8-9 Out The UC07 manual says to put 3 & 7 IN for KDJ11-A for autoboot. UC07 Firmware is set for device 0 autoboot, and it is set for default address. Switches are 0-4=OFF 5=ON 6=ON With either...

So I gave the 11/73 CPU card a try, and I was successfully able to boot to ODT, but I didn't have access to my UC07 - and I'm pretty sure my problem is that I need a grant card. My KDF11-BJ CPU takes the full slot, but the 11/73 only takes half the slot - and from what I've read, you need a...
