Thanks! I recently got a a Macintosh 512k system, and also a 128k motherboard, so will likely flip through the manuals as part of playing with these early systems

They seemed to be a reseller of old parts in to the late 90s, they were selling 68030/040 accelerators until at least mid 1998 https://web.archive.org/web/19980423123432/http://galaxyhp.com/logic.html I just sent a connection request to David Shipway the previous CEO of GALAXY Hardware, to see...

And posted 68k Accelerators: Connectix Virtual and Compact Virtual. I didn't realized that there were two versions, one for non-68030 compact macs with accelerators, called Compact Virtual, and a different version simply called Virtual, for use with computers that have 68030 CPUs, LC's with an...

Found 3.0.1 at https://vintageapple.org/gamba2/system6.html

I'm putting together a post for my site about Connectix Compact Virtual. As part of that work, I discovered that only 3.02 and 2.04 are posted online, but I haven't found any other version.. I actually have Virtual 3.0 RC4 (attached) in my collection as part of the set of disks I got with my...

I've had good luck with industrial CF cards, they are designed for better IDE compatibility https://www.savagetaylor.com/2023/12/17/ide-replacing-your-old-ide-drive/

Most Macintosh computers that have an internal SCSI drive have to have one installed and terminated for external drives to work. So that would explain why it will not boot without the internal drive. Are all your images initialized?

There were actually a faire number of the 68000 accelerators https://www.savagetaylor.com/2022/06/07/68k-accelerators-fpus-and-other-cpus/#68000_68hc000_accelerators

Many of the images you find online are images of a single drive volume and were created for emulators. For an actual Macintosh computer you need an image that also contains the boot driver. I have a guide on my site and image files that may help...

I've been thinking of adding a similar list to my site similar to my page on modern storage options. I also need to update my list of accelerators to include the "modern" versions create by @Bolle and others.

Is there any difference in the max speed you can overclock the CPU for your LC475 reloaded board vs the original?

For boot order, I believe it is the internal floppy first, then the external floppy, then SCSI devices in ascending SCSI ID order. For making a boot floppy, you use the OS. You initialize the floppy and then copy the system file from the system folder on to the disk. You can also use a modern...

You are understanding it correctly for the SE/30 with only an internal device attached. The internal device needs to be terminated, but you do not need to have a terminator on the external connection.

I have some info on my site that covers how various Macintosh systems handle termination https://www.savagetaylor.com/about-us/macintosh-scsi-hard-drive-replacements/#what_is_scsi

There are a lot of TIL articles for A/UX https://savagetaylor.com/til/articles.html

Good to know. I will be trying this in my LC475 soon to see if I can get close to the 6MB/s theoretical max "Note (1): The transfer rate of the 53C96 can reach 6MB/sec when using a fast hard drive, provided the cabling is capable of supporting that speed"

Weird, the IIfx has a max of 3MB/s, the others look like they are hitting their max or close to it https://www.savagetaylor.com/TIL/TA29470.html

That is what I was hoping, that is great news. Now to find the time to experiment. Perhaps a later version of the Apple IIe emulator software added more support for network devices.

Thanks, I added the 1325 to my site using your photos, and used the photos from the brochure you shared to add the Classic and LC versions.
