I have SUM II on floppies. If anyone wants it, I can image it and upload it somwehere

Phreakout - any updates on my board? You've had it a LONG time.

Just for a minor additional note of clarification, I was genuinely puzzled if "MFS Support" was something you were explicitly looking for. Presumably a Mac hard disk which *did* wo…

Confused myself, I meant non-SCSI drive like the serial MacBottom, was probably thinking MFM (correctly or not) having previously written MFS. Not that clarification isn't importa…

Though the fact it distinguishes between the SCSI and non-SCSI HD20 is a good indication it understands MFS. Click to expand... Minor nit: What does MFS have to do with the HD2…

Would be nice to have to see if it would recognize the macbottom serial HDD as it is.

Symantec Tools is a newer variant that sprang forth from the older Symantec Utilities for Macintosh (SUM). I have version 1.1 of SUM. Symantec Tools is part of Disk Clinic (which…

not sure about symantec tools, I am talking about Symantec Utilities for Macintosh Version 1.1 before it became Norton. From the Wiki, it supposedly understands the old HDD systems…

I have something called Symantec Tools 1.0. Is that the same thing? I see in the disk drive parameter volume folder three MacBottom configurations, 20/32/40. It also defines the Ap…

Would be nice if it would talk to the macbottom HDD. Research concludes on macbottom, that Symantec utilities 1.1 would work with HD20/macbottom/etc, but i havent found a copy.

So here's a recent Tecmar drive sale on eBay. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250993088572 So the seller says this: Tecmar made several versions…

nice drawer icons, can you copy them and put them online?

I've just posted another 720p video here that shows the HyperDrive Mac 512 booting to the Desktop: I also shot it from the side while booting, with the case back off.

I just added 11 new HyperDrive photos today: https://picasaweb.google.com/103365672326265854011/GCCHyperDrive20DriveMechanism Be sure to read the commentary beneath each photo, a…

A solid-state HyperDrive will either be very expensive or a lot of hacking. Click to expand... A typical Atari ST IDE board (which would be the same hardware, essentially) is f…

The easy way to put a hard disk emulator in a Mac 512 is to add one of the SCSI-equipped upgrades and Mac Plus ROMs. From there, add a notebook SCSI drive like I have in mine, or u…

Yeah, the emulator products are priced so they might make sense if you desperately need to keep some dedicated industrial computer running. (You'll find MFM or RLL hard disks float…

I found an exact flash replacement for my MMI M112 drive: http://www.datexdsm.com/disc/disque33.html But the price is not shown, which leads me to believe it may be as costly as …

There actually are a couple commercial solutions for replacing MFM/RLL hard drives with either SATA or flash... but they are turn-your-hair-white expensive, unfortunately. (North …

...almost *any* MFM (or RLL, they're the same hardware, just the data encoding method differs) hard drive with four or more heads and of suitable physical size would work as a repl…

I suppose this is useless trivia, but according to the platter/head/cylinder layout (2/4/306) that MMI drive in your Hyperdrive is from a logical standpoint literally a shrunken cl…

Thanks for posting those pictures. Now there IS documentation of an MMI mechanism available. I guess I should post pictures of my old disk drives for reference too. That big list c…

An individual who used to be a GCC HyperDrive dealer in the 80's contacted me recently and we've had a long discussion about our respective units. He inspired me to take shoot add…

I bought a nice 133x Kingston CF card for my WS. 133x is faster than most of the pre-G4 portables can do. It usually maxes the bus on my WS, plus was only $30 something for a 16GB.
