Intel 4004 emulator problems?
Back to General discussions forum
Hi everyone,
Apologies if this has been reported recently; please feel free to delete this post if it's a duplicate.
I am encountering technical issues with the Intel 4004 tasks (specifically "Mul Two"):
Submission Error: Clicking "Submit" results in "failure :(" even with a logically correct solution. If the solution field is empty, it just says "fail".
Emulator Error: On the Intel 4004 Emulator Wiki page, I consistently receive: "Error happened during request to server!" when trying to run code.
Thanks for your help!
Hi Friend!
Thanks for raising the question! Most probably it is yet one more thing which got broken with the recent hosting
provider update which, among other things, dropped support for Python 2 which historically was used for this emulator.
I'll have a look into it a bit later and hopefully we can get it live back soon.
Sorry for it taking longer than expected, but now it should work.
Surprisingly it required only few changes.
There is a larger problem (perhaps for future, perhaps to be opensourced) as I recollect now - our emulator works by interpreting instructions "lexically", rather than converting them properly to bytes and executing this byte-code. This limits execution of some subtle tricks.
Otherwise things should be better now. Please try and report if I'm mistaken.
