in reply to Perl ZX Spectrum Emulator

It doesn't sound so surprising to me.

I've written a MIX (Knuth's imaginary computer) emulator in pure Perl, including a compiler for the MIXAL language, and it works pretty well. Of course, MIX has no graphics whatsoever (only a text terminal).

    A MIX emulator in perl? That sounds great, Wow!

    Update: I once wrote an emulator (but no assembler) for a much simpler processor than either of these in Ruby, and my obfu Re: Pattern matching can be said to simulate an even simpler processor (well, I've compiled it with a simple assembler program I've written in ruby).

[stevieb]: well, what happens is the Arduino 'listens' for requests r/w, and does the appropriate thing when it's interrupted based on the 'register' address sent in. It's ugly as it was my first attempt, but I've got great new ideas I'm just sitting.
[stevieb]: ...down to implement now. Here's the sketch as it currently sits
[shmem]: well I use I2C and SPI and stuff, but creating a pseudo chip looks to me like lot of indirection and memory clutter... not?
[choroba]: Are you going to use the device soon? Related to your comment about "not having much time to do a lot of coding"...
[stevieb]: sure, but I'm just learning ;) I consider it practice to get a good understanding of what goes on *after* an I2C/SPI request is made
[shmem]: ah ok. Gonna read that. but now....
shmem compiles himself into his template
[stevieb]: this is my RPi:: distribution overall automation build system physical layout. It doesn't encompass all of my RPi dists yet, ...
[stevieb]: ...but I'm getting close. I've been soldering my own PCBs to gain that experience as well, before I have my own manufactured.
[stevieb]: heh, nice *template* ;) 'night shmem!
