Is the 8870 such a rare machine? Maybe no 8870 users available here?

Dear All! Since a few years I own a Nixdorf Quattro/7 that I rescued from a haystack. Unfortunately it will not boot. When I try to start the machine, I get following codes on the status display: FF E0 B0 1 - in parallel to this some 2 seconds seeking noise from the hard drive followed by 43/C0...

Give it a try. you can use glass fuses with a reasonable breaking current (like 2.5A) on each rail to be sure you don't have a hard short somewhere

Awesome, @bigfix ! The maintenance manuel is great, thanks a lot for providing the scan.

I have my basement populated with no uVAX2 (yet) but at the moment 3 MV2000 :-)

Dear All! Does anybody have information when the Microvax2000 was build and how many units have been sold? On the total number of VAX machines I find some hints on the internet that is was similar to the number of PDP11s - around 600.000 units sold. Can anybody confirm this? Is the MV2000...

Same problem here! Should a healthy power supply start with no load / not connected to the board?

Is anybody familiar with these test? My 11/23+ starts the disk (the image above) but the test that should take 10mins runs for more then 2h after I have interrupted.... Below the output: Loading DIAGNOSTIC OPERATING SYSTEM - V8.0 PART 1 This will take a few seconds. Please wait...

I can contribute User Tests #1 in Image Disk Format. (C)1985 so probably a newer version than posted above?

I have done it with a MV2000. First step is to create patched ROMS from 2.3 ROMS then burning the ROMS ind installing them in the system and lastly patching VMS. The files are available here: http://ftp.gwdg.de/pub/vms/pk2k/ The MFM Emulator is a fine and more easy solution as well but does not...

Hmmm. Maybe you can ask the developer to send you an SD card image which you can DD with your linux box on your sd-card? Thanks a lot for the link to the RLV12 emulator project, this sounds really interesting.

Congratulations @Schroeder, very nice. The "DECScope" graphics is interesting, in case you try this feature out please share a screenshot :)

Just swapped the two drives, It seems like the error is related to the drive mechanism. But, now when I boot from RX0 with the drives swapped, i can boot but I get a new error "reading handler"... Swapping back to initial state and the new reading handler error disappears again.

Dear All! I would like to ask for some advice how to perform trouble shooting on my dual RX01 drives. I can boot RT-11 on my PDP11 using drive 1 but drive 0 is not working "ERR 17 no disk" I have so far cleaned the drives including heads, the voltages are ok an all connectors seem to be non...

Dear All! Does anybody know what thew purpose is of this module? Is it some kind of fast digital IO? There seems to be a similar module which can put 16bit date in and from memory...
