RX02 *.DSK convert to PDP11GUI Image format

Hi all, maybe someone can help. I would like to install TCP/IP on my RT-11 system. After a short search I have found the following, which I would use: http://www.classiccmp.org/PDP-11/RT-11/freeware/decus11/110939/rthtml/tcpget.htm But the images are in DSK format, but I can't write them with

DECstation 220. Another Impasse

I have reached another impasse in my attempts to get my DECstation 220 to work. I have posted the details on my blog here: https://robs-old-computers.com/2017/08/13/decstation-220-update/ If anyone has any suggestions I would be interested to hear them. Thanks Rob

Re: DEC Unibus, Omnibus and TTL Flip-Chips sought for!

It appears that there is a typo in the BA08 which was kindly pointed out to me offlist. The M023 is in fact a W023 cable! It makes perfectly sense. I should have noted it if I checked the module map a bit more in detail. Thus I do not need a M023. And I do not need a W023 either. The full wish

Hi Jerry, I have tried with PDP11GUI, but the first message says "The image contains only 505856 bytes, but disk has 512512 bytes". I have written some disks, and have ignored this message, but none of them is readable under RT-11. .dir dy0: ?DIR-F-Error reading directory So I think the DSK

RE: VCF?

The overall Chordset dimensions are 5 3/4 for width and 6" for depth. Keys are spaced like regular piano keys, whatever that is. That should help you dimension the drawing you have. We found very few programs that would use it. Marc -Original Message- From: cctalk
