2022-06-03 10:16:27 <tangentstorm> lispmacs[work]: hrm. i haven't touched some of that stuff in about 10 years. that's a pascal port of the ngaro vm from retroforth 10.
2022-06-03 10:17:04 <tangentstorm> i don't know why it won't let you clone the repo though. it's right here: https://github.com/tangentstorm/aggpasmod ... maybe beacuse i used ssh for the link instead of https?
2022-06-03 10:24:25 <tangentstorm> i should really go through and clean up this whole repo, sorry. :)
2022-06-03 10:52:29 <lispmacs[work]> tangentstorm: I tried editing .gitmodules to change the URLs, but for some reason the old URLs are still used when I run "make retro"
2022-06-03 10:52:42 <lispmacs[work]> presumably I need to run some other git command first to update something
2022-06-03 10:54:11 <tangentstorm> i honestly don't remember. there's a bunch of different prog
2022-06-03 10:54:58 <tangentstorm> er... varations on this overall project all in that one repo. the stuff i'm working on lately is mostly in the 'turbo' and 'j' directories.
2022-06-03 10:57:26 <tangentstorm> the old ngaro vm was pretty cool though, and that version had nice graphic support. i will try to get it working this weekend if my kids let me. :D
2022-06-03 11:01:26 <lispmacs[work]> just was curious to give it a try in dosbox
2022-06-03 11:03:11 <thrig       > hey kids want to learn about old computers?!
2022-06-03 11:03:19 <tangentstorm> oh. the retro stuff never ran under dosbox. only the turbo directory. (and i'm not using dosbox currently so i can't guarantee it hasn't broken)
2022-06-03 11:03:40 <tangentstorm> right now i'm just using free pascal under ubuntu.
2022-06-03 11:04:32 <lispmacs[work]> tangentstorm: oh, okay. Well, I've got free pascal installed on my Guix system. What command would need to run in the repo to build that
2022-06-03 11:05:29 <lispmacs[work]> I see there is a makefile in turbo directory, whill try that
2022-06-03 11:07:17 <lispmacs[work]> I can't build b4 because I am missing include file "xpc"
2022-06-03 11:07:50 <lispmacs[work]> submodule I need to clone?
2022-06-03 11:08:41 <tangentstorm> https://github.com/tangentstorm/xpl
2022-06-03 11:09:20 <tangentstorm> sorry for the mess. i really wasn't expecting anyone to want to try this yet. :D
2022-06-03 11:09:49 <thrig       > put it in CVS to make it hard to use
2022-06-03 11:11:11 <lispmacs[work]> Okay, I'm interested, but getting all this compiled is getting to be a bit of a project. Maybe you can let me know when you have the makefiles cleaned up
2022-06-03 11:12:22 <tangentstorm> okay, i think that's probably a better idea. i appreciate the interest!
2022-06-03 11:13:48 <tangentstorm> what i'm working towards here is a video series about building a virtual machine, and then bootstrapping a forth and a pascal compiler on top of it.
2022-06-03 11:15:21 <tangentstorm> i'll probably keep changing things wildly until i can tell the whole story (stripping down the list of opcodes, etc)
2022-06-03 14:14:24 <KipIngram   > tangentstorm: always wise to avoid trying to "nail down" a project until you've got the big picture well in mind.

2022-06-03 16:53:13 <KipIngram   > I think Forth and formalization have mostly different audiences.
2022-06-03 17:00:35 <KipIngram   > Oh, they seem to be working with a separate "control flow stack."

2022-06-03 20:50:08 <KipIngram   > Do you mean that each line is treated separately?

2022-06-03 21:10:17 <vms14       > actually it's funny because I always wanted to get rid of the rpn by reversing lines
