Thanks @killvore! Located in Anchorage, Alaska, which always makes shipping fun (to say the least). But I am on the road system, and USPS shipping prices are the same as the Lower 48. So that would be the way to ship. Totally OK with Q610 instead of C610. Blank Bezel would be preferred. Feet...

I purchased a nicely restored C610 motherboard from Will at the CayMac team. I am going to work on some overclocks and ROM hacks. So now this means I am in the market for a C610 case :) In search of, if anyone has any leads!

Wanted to share this write-up. I only get credit for 1 very minor fix listed in here. Otherwise this is a collection of knowledge from many different people. I would be happy to give specific credit to specific hacks :) But I wanted to make this a living document for 1024KB ROM hacking. There...

Thank you! I just downloaded that repository, so I'll take a look at all this. Seems like a ton of good information in there. The little project I am working on is building my own variant of the netBOOT driver from scratch.

Do you by chance know where I can find more details on combo bits? I found some old threads from bbraun indicating some documentation showing IIsi has a default combo bit of 4, but 3 if an FPU is installed. Is this stuff documented in Inside Macintosh somewhere?

I've been talking with the great proprietors at CayMac. We fixed the LC475 ROM so it should reliably boot to ROM when holding down R. The Q950 ROM should likewise be a very easy fix. Take a look at their github page, they already have the new LC475 ROMs available for download. I actually have...

This is just awesome! You rock!

I'm certainly learning that the LC475 is in the odd space between the smaller and cleaner 128KB ROMs, and Super Mario. But with Netscape v4, the Dayna WiFi with BlueSCSI, I am actually able to get out to a lot of websites. It is pretty usable. Might even be worth doing a short-term daily-use.

Yes, the POST is so fast now, really incredible. I have this hooked into an LCD monitor. It really doesn't take long for the monitor to wake up. But by the time it does, the desktop is just about loaded. So all in, maybe 10-15 seconds to fully boot. I love it :)

So cool joevt! Just looking into your script now. Thank you :)

Wanted to show my MARCHintosh project. Here are the mods- 1) Board and PSU recapped (by last owner) 2) Modified board to run at 33MHz (by last owner) 3) Full 68040 40MHz, coveted 02L88M, with added heat sync 4) BlueSCSI v2 with Mac OS 8.1 of course 5) 1MB 70ns VRAM 6) 128MB 50ns RAM 7) CayMac...

Thanks for the pointers! I'm reading through right now and learning a lot. Just bought an old book on 68000 assembly to get up to speed. Although my degree is in computer science, it has probably been 20 years since I've done day-to-day programming. Told my wife, 68K was the perfect mid-life...

Also if anyone has a bin_map and bin_names for the LC475 / Quadra605, that would be very helpful...

I know there have been posts similar to this. But I've worked with some tools such as FDisasm. I can't seem to really get a reliable or full disassembly of the LC475 ROM. I would like to get to this point, so I can dabble with ROM programming using some SIMMs I purchased from CayMac. Can...
