Hi Pontus, Vince and I developed the Blinkenlight boards some years ago. It uses a Core board with 6809 CPU and an I/O Board that has 64 digital outputs (8 LS374 latches) and 64 digital inputs (8 LS373). It is capable of cascading up to 6 I/O Boards to one Core Board. But the design is from 2004 or so ... have a look at this: http://www.j-hoppe.de/PDP-11/PDP-11_70_console_panel/11_70_panel_-_Physical/11_70_panel_-_physical.html - Henk. ___ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
Re: [Simh] Hardware Requirements
Has anyone have any experience of running on an ARM cpu? I'm asking since I'll need some I/O pins to connect with the real console I have and there are some nice ARM based development boards out there with lots of I/O. I've built the pdp11 emulator for my android phone (ARM). Ran fine, though I didn't make any performance measurements. - Pontus For a small OS, TinyCore Linux makes a nice distribution for throwing together a small image for a dedicated purpose.

Re: [Simh] help with 7090 simulation
Hi, This is a little weird, but I'm interested in trying out the 7090 simulation in SIMH even though I've never used a 7090. Unfortunately the FAQ link on simh.trailing-edge.org doesn't work. http://simh.trailing-edge.com/simh_faq.txt I downloaded the Windows binaries and unzipped them. Then I unzipped the 7090 IBSYS package into the same folder. I started i7094.exe and did do do_ibsys.txt. At that point I'm left with a few messages I don't understand and the simulator doesn't appear to be responding to input. I can't help much with Bob's 7090 sim, however mine is available at http://sky-visions.com/ibm near the bottom of page. This works with current SimH, just drop I7000 into simH directory and type make. This will also give you sims for almost all the IBM 7000 series machines. Also check out my IBSYS page: http://sky-visions.com/ibm/ibsys.html Tapes for pretty much everything that is currently available for IBSYS are available here, along with sample jobs. sim do do_ibsys.txt Could Not Find C:\tmp\simh\punch.* The syntax of the command is incorrect. sysin.txt: No such file or directory CDR: unit is read only CDP: creating new file MTA: creating new file MTA: creating new file MTA: creating new file MTA: creating new file MTA: creating new file MTA: creating new file MTA: creating new file MTA: creating new file IBSYS is a batch system. There is no input from console. Only input comes from card reader or input magnetic tape. I have many sample jobs on my site, however most are in Fortran II or IV. I also have links to revelant manuals on bitsavers, so you don't have to figure out which version is correct one. Ultimately my goal is to get MACRO-FAP assembled on the 7090 simulator so that I can experiment with its behavior. I found an assembly listing for it at: No need to bother. This is already gened on system tape images. After I get CTSS stable I will go update these web pages to add some more info and some detailed instruction on how to set up a job stream. Along with CTSS and some new Lisp 1.5 stuff.

This works with current SimH, just drop I7000 into simH directory and type make. Well, I'm on Windows so typing make isn't going to do anything useful out of the box. Do you have a windows binary already built? Ultimately my goal is to get MACRO-FAP assembled on the 7090 simulator so that I can experiment with its behavior. I found an assembly listing for it at: No need to bother. This is already gened on system tape images. Do you have any documentation for MACRO FAP? I'm only getting into this because I want to build an implementation of BEFLIX, which is apparently implemented through MACRO FAP. The BEFLIX sample code that I have uses the IFF pseudodirective for MACRO FAP and the MACRO directive. That's why I want to play with MACRO FAP, to understand these directives. -- The Direct3D Graphics Pipeline -- DirectX 9 draft available for download http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/ Legalize Adulthood! http://legalizeadulthood.wordpress.com ___ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
