I promised to look into this. There are some prerequisites to do first: 1. Finish the "NG display" pull request: https://github.com/simh/simh/pull/642 2. Build on 1 to provide inputs from USB...
Hello, I have found a 1977 copy of "The MDL Programming Language - Primer and Manual" on the Dynamic Mocdling PDP-10 backup tapes. Here's a file listing: ``` 03 !FRONT...
I haven't had much time to work on this. I'm just posting this work-in-progress to make it visible.
In the current implementation of the clocked CPU, the cycles for exceptions go unaccounted for. The reason is probably that an exception occurs in the space between one instruction ending,...
More completely model the IRC/IR/IRD prefetch queue.
The Phalanx Demo F1 screen doesn't work. A short while after it switches to medium resolution, it tries to execute a `000F` instruction. Which is illegal, so the CPU stops....
There are a few black pixels in the BIG Demo main screen. They probably first appeared with the new shifter reload logic.
It's tedious to continuously check that all demos keep working when something in the video components change. I plan to rip out the juicy bits from various demos, and put...
I believe the problem getting Phalanx Demo to work (see #77) is related to a missing MFP interrupt latency.
Clocked CPU
@stefanberndtsson is planning to convert the CPU component into a clocked design. Would it be possible to jot down a few notes here every now and then to get a...
