Re: [Simh] pdp11 and unix

Hello! Version Zero was hand coded on a PDP-7. Included the necessary tools to make the tools, that is the components we use now on the ones on the PDP-11 to write programs. As I understand it, but I believe there are people on the list who know more then I do,and can chime in; the gang at Bell

[Simh] Adding Unix v0 support to PDP18b

1. Create an RB09 variant at half size and allow it to be configured in the PDP7. No need for dynamic size support; Unix v0 supports one size (8000 sectors), and PDP9 software supports one size (16000 sectors). 2. Create a card reader for the PDP7. With minor mods, the same device could

Re: [Simh] pdp11 and unix

Bill, There is plenty of documentation on the pdp11 45/70. Start with the handbooks: http://bitsavers.trailing-edge.com/pdf/dec/pdp11/handbooks/ As for programming in assembly, most of the documentation is for DEC OS's. However, the manuals for Unix v6 and v7 had assembly sections. They are

Re: [Simh] Questions about PDP-7

SimH stores 18b data, whether disk or DECtape, right justified in a 32b container. As for ASCII data... "it depends." DEC's own software for the PDP-7 used a mishmash of character sets, including FioDEC, Baudot, and the early form of ASCII associated with the KSR-33. The official assembler

Re: [Simh] Klh10 vs Simh

Hi, I have a working KA10 and most of the pieces to make a KI10. If anyone is interested in helping let me know. I need help with the dectape controller. If someone has the protocols for the console between the KL10 and the FE, I could add in a KL10A to my mix. From KI10 to KL10A is not

Re: [Simh] Klh10 vs Simh

I've been hoping for a KL simulation in SIMH for a while. KLH10 lacks support for things like serial over Telnet which means that multiuser is essentially impossible on KLH10 without all kinds of networking mojo. Sadly, I don't have the skill to actually write such a beast, I'm of no use except as

[Simh] Klh10 vs Simh

Hi All, I’ve begun trying out Tops-20 on the KLH10 emulator, and also have an interest in ITS for the sheer novelty of the operating environment. I don’t know a lot about PDP10 CPU families, but was wondering how the two emulators compare. I gather DEC didn’t release newer versions of Tops-20
