The PDP-10 (specifically the KA-10) was the first computer I ever used and my first job was as a TOPS-20 assembly language programmer, so I wanted to play around. I am on a UBUNTU linux system. After some bumbling around I got it built and it 'starts' ok Compiled for unknown-linux-gnu on x86_64 with word model USEINT Emulated config: CPU: KL10-extend SYS: T20 Pager: KL APRID: 3600 Memory: 8192 pages of 512 words (SHARED) Time interval: INTRP Base: OSGET Interval default: 60Hz Internal clock: OSINT Other: MCA25 CIRC JPC DEBUG PCCACHE CTYINT EVHINT Devices: DTE RH20 RPXX(DP) TM03(DP) NI20(DP) [MEM: Allocating 8192 pages shared memory, clearing...done]

It just stops here with a zero length file created. Does anyone know what I am doing wrong? When I try the inst-klt20.ini file, it can't find the .tap file. Any help would be appreciated. John

I figured it out after another hour or two of searches... It's up and running now!

What did you have to change?

I had to download the tape image (from trailing edge) and use that to populate the rp06. There was a good sample session I was able to find and follow.  I forgot how complicated old systems were to install. On Jan 27, 2024, at 3:11 AM, Eric Smith @.***> wrote:
