Are two terminators necessary/supported in the 11/05? I see two in the above photos. Perhaps as also previously suggested you cant try terminating at the end of the first backplane, that will eliminate the issue being in the other two backplanes.
Thanks g4ugm for the offer but I think I've made good progress. I dug out an NEC SCSI CD-ROM drive and while looking in the box I found a DEC RRD43, I've previously only tried known good working RRD42 drives from my VAXstations's.
I connected up the NEC drive and attempted to boot (boot...
I have been struggling to burn the Ultrix images to CD-R but after a lot of trial and error and testing I've managed to burn both a 4.3 and a 4.5 iso. I used UltraISO but had to throttle back the write speed of my writer from 24x to 4x. I can now boot both the 4.3 CD and 4.5 CD but after...
I've been given an image to trey from a DEC enthusiast in the UK to try (Thanks Rob(y)). I'll give that a try next week. Here are some photographs of the shorted diode in case anyone else has a dead DECStation/DECSystem 5000. I intend to replace the diode.
I've had a DECSystem 5000/240 for a while and recently decided to check it out. I cleaned it up and tested the PSU offline and it appears OK. I connected the PSU to the system board via the large ground and +5V cables only and no issues, PSU fans turn and some LED's are active. I switched it off...
Hello Verault, the connector for the keyboard will need to be the female socket version of the connector on the end of your LKxxx keyboard.
LK201 keyboard springs to mind, some info is below I don't know a place that stocks the socket (4 pin) but I don't think it will be that difficult to...
Hi Dave,
A little rusty but you have to select the DSSI device from the command prompt for example and may not be exact syntax, it may also be different for different VAX models but at least it is a start.
>>> SHOW DEVICE
Then select DSSI controller, its number 5 for example from show device...
AK6DN's comment above about a virtual device reminds me of a configuration that I used to support on 11/70's. The customer had a 4MB Dataram BC202 attached at the end of the Unibus as a "fast disk" called DF0: in RSX11M. I think it emulated a DEC RF-11. Comparable now to an SSD cache tier in a...
