There are a great many available on eBay made by Adaptec. Just search for "adaptec scsi Mac"
You don't need anything fancy. A 2930CU should be fine, though youll need an HD50 to DB25 adapter, which are cheap enough. Just be sure it's an actual Mac edition card. They will work with 8.6.
 it's unlikely youll find an cn50 to IDC50 as IDC50 is an internal connector. Iomega made HD50 to DB25 adapters which they included with their Jaz drives so you could hook up normal DB25 cables. I have one myself and it works great. Again, cheap on eBay. Quick search saw ones as low as $13

Firewire-to-SCSI is prohibitively expensive for what you are wanting to do. It would be the most expensive option out of everything you've suggested, because those adapters were rare even when they were being made. They're quite expensive on the secondhand market now.

ZuluSCSI, and its predecessor SCSI-2-SD is a reasonable alternative. There are flavors of the hardware that instead of using an IDC50, have a external DB25 connector.
I have several SCSI-2-SD devices which I use for my music sampler hardware. I have not used ZuluSCSI but from everything I have read, its less easy to use than the SCSI-2-SD was (SCSI-2-SD was discontinued due to part scarcity) but offers more or less the same functionality.

This SCSI card has DB25, so no adapters needed:

Thanks @robespierre. Seems that now we’re getting closer to what might actually be deemed a “Proper” solution for this specific task / application.

After reviewing more info from the Dowsil 738 SDS, it is also an RTV sealant? And if so, perhaps the Dowsil 748 sealant might be a better alternative for those concerned about acid release during cure - as the 748 is a “neutral cure” silicone adhesive sealant?



As we’ve now nearly beat this horse to death... and as this has veered from the focus of the original thread to a tangent of its’ own... thus the new Topic.

Once again, whether one decides to replace the PSU goo or not (and with whatever they might choose) that is entirely up to the individual. As for me, I’ll continue to use RTV silicone for this.

Many options, opinions and specifics have been made abundantly clear here at this point and any further posting(s) that may be deemed as excessively argumentative or redundant will simply be deleted and this topic possibly locked.

i have read conflicting information like you can enable the modes if you use particular monitors or if you replace the monitors extension with some specific older version, etc etc

it seems like one of those things though where the only reason programs wont run in higher color modes is just because the program itself is set to stop running?  like even if the system were in 256 or higher, the program would still run fine...if it wasn't closing itself down?

in all the years of mac tweaking is there no trick to either 1) get those modes available in OS9 or 2) trick the program into running anyway?

if it is part of the resource fork compression/decompression then either who would know about how to fix that or what would be involved in fixing it?

hellcats would be the most important victim of that but after dark is awesome also

this is the main reason i would go all through the trouble of the 8.6 firmware trick but on a fw400 mdd that might not even work

actually the main reason i got a g4 is i wanted to run hellcats at the highest possible resolutions  ...
so i was pretty disappointed to find out about this bug  :'(

hellcats was programmed so great to even have those resolutions available, if only more classic flight sims had that options, for most games it doesnt matter but flight sims definitely benefit.

did the same dev make another mac flight sim with an improved engine?  i remember another flight sim that came out a few years later that looked very similar tho it had modern jets.  maybe if theres no way to fix OS9 there could be a way to port the hellcats missions to that other engine
