This is where Mac-on-Linux comes in. It also provides convenient display and audio driver abstraction layers. I'm also not sure you're correct in the assertion that _all_ embedded PowerPC CPUs are this way. The e300c3 core is _not_ Book-E, which is what I believe you're referring to.

T There's no such thing as a BlueSCSI specific image, or a SCSI2SD-specific image. This is an extremely common misconception. So-called "HDA" files are just raw byte-for-byte dumps of an Apple Partition Map-formatted disk image, containing one or more HFS/HFS+ volumes, _exactly_ like you'd get...

Here's an example of one of the ways I intend to adapt this new PPC compute module to. This was made by Embedded Planet, and sold by Freescale as the CWH-PPC-8248N-VE. Embedded Planet (actual designers/manufacturers of the board) referred to it as the CWH-PPC-8248N-VE

I chose the MPC8313 specifically because of how inexpensive it is to obtain, as of ~2023. There are certainly more performant chips out there from the same/successor families, but they're 2-4x the cost, if not more. I wanted to make something that was affordable enough to manufacture 50-100 at a...

I wish that were actually the case, but nearly all MPC8313E's are NRND, and all distributors have zero supply of MPC8313's at this point in time. That said, it isn't really a problem, because there's plenty of new-old-stock, at far more palatable prices.

There are far lower-cost ways of achieving that. This is a _PowerPC_ based board.

What if you could build a 603e-based Power Macintosh computer around existing, new-old-stock PowerPC-based chips that nobody wants any more? Fifteen years ago, in mid-2007, while the first iPhone was making front-page news around the world, Freescale Semiconductor announced the MPC8313...

Sure, it's "enough" in the context of slow-speed serial links, but that wasn't really the point of my original post. OpenTansport is faster, that's a simple fact. There's nothing wrong with using MacTCP as long as you don't care about throughput.

@David Cook, this is awesome. Have you successfully been able to transfer data serially, and if so, at what speed? I just recently made some similar PCBs, which are designed to have either an ESP8266, Raspberry Pi Pico, or generic "blue pill" board (choose one), which then attaches to the serial...

The problem here is that ZuluSCSI _is not a SCSI2SD device_, nor is it advertised as such. I strongly recommend you read the manual linked above, and email us with any specific questions you may have, after doing so.

We simply used BlueSCSI as a starting point, which is the right of anyone to do, under the terms of the GPLv3 license, which you chose when you forked the project. Nobody is disputing that it's been nearly completely re-written. See the use of the term "derived from". Even the AzulSCSI firmware...

Except that isn't what happened, if you actually look at the commit history. Only the SCSI command handling code is from SCSI2SD. It's a fact that BlueSCSI users can remove an SD card from a BlueSCSI, plug it in to an AzulSCSI, and it will boot. Nothing you choose to say or do will change this.

....which is still a measly 1.6 megabits. Classic MacOS network stack never, ever performed well, and Apple never seemed to care.

Of course it is, but that's not what my post was about, or intended to address.

If you have 6-8 megabytes of RAM in your cmassic Mac, here's why you should use OpenTransport instead of MacTCP... On my Quadra 650, with 40 megabytes of RAM, System 7.5.3R2, using the built-in AAUI Ethernet interface. Rrunning MacTCP 2.0.6, when downloading a multi-megabyte file from a local...

Send me a PM with an address, and I'll send you a SCSI2SD V5 at-cost.

I'm so sorry. I recently had to do this with my beloved cat of 10+ years, a couple of months ago, and I felt gutted for a couple of weeks. Hang in there.

Thanks, this is good information to disseminate, but that's so strange. Which version of the pickit do you have?

Very sorry to hear it. I sent you a PM just now with an offer to help, if you're interested.

@bdurbrow am I? I'd like two. I messaged you here a while back but got no response
