Mr. Craig sent me several Mac-formatted floppies containing CompactPro archives of disk images of the LOS disks. (Whew! Did you follow that?) He also sent along the older version of Apple's Disk Copy (4.2, I think) which will happily make disks from images it cannot mount. (It also knows to make an 800k floppy be 400k if that's what the original image calls for.) Obviously, somewhere along the line, he was able to make the images from the original Lisa diskettes, but I don't know the details of this -- Disk Copy must be able to make images from weird disks (I know it can do ProDos ones.) Incidentally, there is a way to de-serialize LOS diskettes using FEdit -- I don't know where your set of disks came from, or whether they've been used. (The LOS install disks have to be un-write-protected because the first time you install the software, the installer reads the Lisa's unique hardware serial number and writes it to the disk for piracy prevention. If you ever try to install the software on another machine, it won't let you.) What's the matter with your Lisa? -- MB

Lisa II operating software

by bobstek＠ix7.ix.netcom.com

Let me make an offer (without knowing exactly what I'm getting into...) I haven't been following this thread too closely because I've never had a Lisa or even a Mac...until yesterday. I now am the proud (but ignorant) owner of a fully working 1 MB Lisa 2 (the Mac XL variety) with the 10 meg HD and 3.5" disk. If given explicit instructions on how to de-serialize, I'd be happy to make copies of whatever disks you would like. And since I've been short of time (and I'm lazy!) I'd appreciate a few choice URL's with solid info of all sorts on the Lisa - less on its history and more on hardware and software, operational hints, etc. Bob Stek bobstek(a)ix.netcom.com

Mac Portable problems (was Re: Mac Portable batt charger)

It is Apple-labeled and has an Adaptec-based SCSI controller. Could have Apple taken a stock CP hard drive and grafted a different controller card onto it? The interface from the drive hardware to the drive electronics seems to be standard (i.e., an 18-pin pin-header interface), so maybe Apple swapped controllers. It does have a proprietary SCSI pin-out, though, for which an adapter is available to connect a sdandard SCSI drive to the portable.

Apple ///

by tomowad＠earthlink.net

>My school had a bunch of Apple ///'s, and also a bunch of Apple ///+'s. >The ///+'s are definitely marked as that. Unless the "+" got rubbed or >scraped off of yours... Nope. That's definately not the case. I guess they're both slight variants of ///'s. Thanks for the info, everybody.

Apple ///

by tomowad＠earthlink.net

I just purchased an Apple /// and noted some interesting differences between the new Apple /// and one I've had for a while. Upon turning on the new ///, it displays some garbage, then beeps and shows "Diagnostic RAM" on the screen, along with a square pattern of '.'s. Not until I press "Reset", does the comptuer dead the floppy drive My old Apple /// (which, BTW, I beleive to have some bad RAM) immediately starts reading the the floppy drive with no "Diagnostic RAM" or need to hit "Reset". Also noted: The new Apple /// has darker keycaps The older Apple /// has a shielded "Color Video" Port On the tags on the bottom of the units: The older has a place to check off either 64k 96k or 128k (128k is checked) The new has a place to check off either 128k or 256k (128k is checked) I understand there was an upgrade to the Apple /// dubbed the "Apple ///+". I was under the impression the '+' was actually written on the case. Is this the case, or is it possible my newer unit is a ///+? If its not, what causes the discrepancy in startup procedure? Just minutely different versions of the Apple ///, or does the older units bad RAM have something to do with it? Thanks!

Mr. Craig sent = I would guess that the Mac disk controller would be able to read the later 3.5" Lisa disks. Of course this doesn't help with the 'twiggy' disks. --- end of quote --- Right, but in this case it was specified "Lisa II" which means no Twiggies.

I'm Back!

Wow! It's amazing how different a CRT looks after three weeks' break. I don't even feel like sitting at a computer that much anymore. Sorry to start off again on a bad foot, but does anyone know why a certain hard drive of mine won't spin up unless whacked firmly against a table? Is there anything I can do?

[Fwd: Old plasma display]

by ecloud＠bigfoot.com

I'm looking for some info on old Panasonic plasma displays. For those of you who have computers that use them for sale, I might be interested in paying a reasonable price for one just to get a working display so I can measure the voltages and get all of them working. I have the controllers for the touchscreen and would especially like to get that working. (Forward of message I also sent to Panasonic and ELO:) Shawn T.
