If you're setting up Snow for the first time for MARCHintosh, this archive will save you a lot of headaches:


It includes not only ROMs for the machines themselves, but also ROMS for things like video cards and odd accessories.

Check it out!

Got it up and running! Certainly seems to run more like the speeds of my SE/30… now to try my development and optimization efforts on it! Thanks guys!!
 
Spot on guys — I was getting about 2fps on my real se/30 and am getting what seems like the same thing from Snow!. Very cool and saves me the 5 minute transfer process from macbook to SE/30 just to do iterative on-target testing! At the very least i can reduce how often I do a self checkpoint like this!!! VERY AWESOME!!! Thanks for the effort!!
 
I'm glad you figured it out!

The next step I took was to use a portrait monitor video screen, gives real good screen estate for coding in Symantec C++ 6.0.

I’ve been looking for more video roms for using Snow for other machines (all set on the se/30 for now but i wanted a mac iici, iifx, and quadra 650, 700, etc). Starting with setting up a Snow version of a IIci I got stuck looking for a video ROM. The ROM link at the OP of this thread doesn’t have a IIci video rom that i can tell — no luck web searching… :(. ANy leads/clues folks?

The very post above yours has a screenshot of the ROM I used for the machine as well as video. That's only good if you're going for portrait. It's part of the pack linked in the OP . If you want a standard screen, iirc it's also possible but I don't remember off hand. I'll have to check until I'm back home.

thanks — i wanted a ‘stock’ setup at least one that didn’t have a custom display card - just a stock machine. If you or anyone has leads on the stock display rom that’d be awesome.
 
Ah - I think I found one: it’s located (relative path to the big ROMs archive) in:
Mac_ROMs/Misc/Video cards/Apple Macintosh Display Card 8-24/Trident 8-24/341-0868.BIN


I only guessed it since the dialogue box in Snow suggested needing 341-0868 so I just searched around until i found it. it wasn’t in the Macintosh II folder which didn’t help me guess it.
