I see, that's very cool. I wish I had the real documentation, it will take me a while to transcribe all of the bit codes by hand

That is exactly what I wanted! Thank you so much Dave. I assumed that that document would only contain schematics and no such informations. Will look more closely next time.

Hello everyone, I am trying to define an implementation of the KD11-A processor in Verilog, for emulation purposes. In the KD11-A Processor maintenance manual I found basically all of the information that I need. The only thing that's missing are the exact output for the microcode ROM for each...

Thank you so much! I didn't know that the ADV11 boards where rembranded DT boards, interesting. Unfortunately this specific board is used to capture and manipulate PAL video and I dont think I've ever heard of such DEC module existing. I'm going to be on the lookout for other rembrandings though.

Hi everyone, I've just acquired a Data Translation DT2651 board and I'm waiting for shipping. In the meanwhile I was trying to look for some documentation for it. Does someone have the manual for the card? I've only been able to find ads on the internet archive...

Thank you! This is precious information. I understand that my journey for a unibus pdp 11 will be way harder than I thought

That's a good idea but unfortunately I dont think that's an option for me. I'm planning on using the emulator in an environment where 'realistic' execution time should have somewhat of a meaning. So having micro ODT as a normal memory mapped program would make that generalization that much easier.

Thank you! If it's normal instructions I should be able to run it. Not sure about converting verilog to software since I'm working with rust with webassembly.

Thank you, this is really helpful, I'll probably take this approach.

Thank you that will be really helpful!

Thank you, I guess I'll go about implementing it in high level code then. I was hoping that there would have been a way to abstract the cpu to just an instruction executer and the microcode as just some code in memory space.

I'm trying to write a PDP-11 emulator that emulates a KDF11-BA cpu board. The problem is that I dont know what's the best way to go about emulating the micro-ODT interface. I assume that there are no 'dumps' of the microcode and even if they were they wouldnt be standard opcode instructions so...

I guess I learned the hard way

Both seems like expensive options...

Thank you everyone for the suggestions, I guess I'll have to decide a model and stick with that one. The 11/04 seems the most promising so far.
