Did anything ever happen with this?

For anyone interested, a complete nView for a Mac Classic. I would watch first, as they sent me an offer for ~$30-something (listed at US$55). https://www.ebay.com/itm/255829989948

Just got one of these enclosures for cheap on ebay. Since it has no drive installed, I have my options for what I want to do with it. Thanks for the teardown instructions! Do we know the dipswitch settings for the SCSI ID?

Ah, I didn't even think of that, but you're absolutely right, that would probably be a nightmare to try and recalculate on the fly for every file on the volume. But your workaround seems reasonable, since it wouldn't make any difference to the user, and would be much faster. I'm guessing that...

Would it be possible at some point in the future to modify the size of a single volume image? For instance, I have a disk image I use with Mini vMac that I'd like to enlarge without having to transfer its contents to a new image file.

If your Mac II's batteries needed replacing, they would replace the soldered-in batteries with one of these, so future batteries could be replaced more easily.

This really is a wonderful project that solves so many problems in the vintage Mac community. Someone may have asked before, but are you accepting donations for development?

Have you tried leaving it plugged in for several days before re-testing? It was the better part of a week for mine.

Wonderful news! This really ups the ante being able to make partitions ahead of time in a modern environment without having to fiddle with emulators. Plus, HD SC Setup is fiddly to use even in the best of circumstances...

I know that some later Mac IIs had a footprint for ROM SIMM slots, meaning it's possible to swap out the 4-chip ROMs for a SIMM (like a ROMinator). Unfortunately, my Mac II is one of the earlier ones and does not have that footprint. Wah wah.

Welcome!

One of the boxes I received:

These are from the Macintosh II Repair & Upgrade Secrets. The third screenshot delineates which Mac II has which PSU.

The Mac II/IIx and IIfx can have either a Sony or an Astec PSU. The IIfx PSU is "thermostatically" controlled so that the fan speed varies with temperature, whereas the II & IIx's PSU goes full blast at all times. Otherwise, they are identical I believe.

Good to know! I guess if you have an '881 FPU and you intend to make use of the Math Co-processor on your vintage Mac, it would be worth upgrading to the '882.

I was able to get a PMMU for my Mac II for not too much. I don't know about speed increases, but I know it enables more RAM to be available. I believe it's also required for Virtual Memory (not that I plan on using it for that).

You may be correct! I am by no means an expert on the subject. Will be interesting to see the side-by-side.

Ugh, horrendous.

As for 68881 vs. 68882, any difference will be marginal, assuming they're the same clock speed. My understanding is that the 68882 was essentially a bug fix.

An FPU will only noticeably affect performance when using applications that are designed to make use of them for Floating Point calculations. 3D graphics, spreadsheets, and other such programs.
