if you want to mess with Mac ROMs now, I think Ghidra is a nicer experience than most of the vintage tools, and you can use QEMU with GDB (at least for the Q800 ROM).

>Do you have anything specific you'd do with an Altix 3000?

nope, I just like weird computers and distributed systems, itanium is possibly the weirdest CPU architecture that modern linux can run on, and SGI is an interesting part of computer history.

numalink, 1.6GB/s in 2003!

there's an altix 3000 on ebay that I'm kinda tempted by https://www.ebay.com/itm/174917876903

it only runs like one specific version of suse or red hat

I was looking at my qube 3 this morning and thinking I should sell it; I never got around to hacking it up as a compact PC case

send me an email (this username at cy384.com) if you're interested!

yes, I think I'm going to make a dozen or so copies, just to make it feel real

thanks, I had fun making it!

there's full design for a box and a floppy label that I've made for the upcoming 1.0 release

it's no problem, the killer feature (that it works at all, and can connect to modern servers with default configs) is solid, and more people using it will help flush out bugs

if you want to go period-appropriate, you can run Macintosh Programmer's Workshop or CodeWarrior natively

I use retro68 on linux, which is a modern GCC toolchain, so it's just like developing any other C/C++ (well, without some nice debugging tools, and with the added complexity of the mac OS resource stuff)

https://github.com/autc04/Retro68/

the GUI code for the earliest macs was absolutely a great feat of engineering

by getting my hands dirty with the system, I'm impressed by the way things were designed for the wimpiest processors (and also getting a lot of insight into the flaws of the OS that were exposed as machines became more powerful)

more specifically, I should say that re-rendering everything is kinda slow, the DrawText function which, uh, draws text, seems very heavy

blitting from a buffer onto the screen is, indeed, pretty fast, I've been experimenting with it and have some ideas for speeding things up

unfortunately, file transfer isn't in yet, but it's the next feature I'm working on, probably within a week or two

the crypto code actually has some 68020 assembly (credit to the mbedtls devs), it could probably be made faster, but I would need to sharpen my assembly skills a lot

doing the initial key exchange before timeout is barely possible for a 68030 at 16MHz, takes the better part of a minute!

of course, on the later PPC machines it's a complete non-issue

oh hey everyone, author here, ssheven is still beta quality, so I wasn't really posting about it anywhere yet, but it's usable and has the core functionality working ok

I plan to do a writeup about it, and the experience of developing for old macs, once I finish the 1.0 release

edit: btw, this is my first project for the classic Mac OS, I hope to inspire others to also jump in, retro68 is a very usable toolchain (big thanks to Wolfgang Thaller/autc04)

bike tires have a manufacturer's specified width, but it's very common for the actual width of any given model to be 1-3mm wider

for competition purposes, there may be maximum widths (depending on the exact rules, more like 33-38mm), not based on the label but measured directly
