1 Operating System / What version of System 7 for this Mac?
August 19, 2015, 01:43
Isn't the Control Strip extension usable as a stand-alone install under 7.1? I may be remembering wrong, but that (like various other add-ons, none of which I currently can remember names of) I had thought could be installed on slightly older Systems.
2 Operating System / Change the caps!

I have it on good authority that the surface-mount electrolytic capacitors on Mac motherboards of that vintage are extremely failure-prone and, even worse, destroy the board when they do fail. I urge you to get your board recapped while it still more or less works. See discussion of this issue on the 68K Mac Liberation Army forums (68kmla.org).
3 Development / Need a Macintosh Programmer

I also am very interested in this. Alas, Versamac.com no longer exists, if it ever did. Anyone got more information?
4 Hardware / You have three options.
May 26, 2013, 06:29
First option, find a SCSI to Ethernet bridge. Several were made back in the day. Second option, find a LocalTalk to Ethernet bridge. Third option, string a telephone patch cable between their modems (you’d need to add an external modem to at least the Classic) and do some trickery with the modem initialization strings. That one probably limits you to old protocols like Kermit and is not terribly reliable or user-friendly, though I did get it to work once.

I'm not sure how well the second option (LocalTalk to Ethernet bridge) would actually work with a reasonably current-model Mac — I don’t know if there are any such bridges that work with any flavour of TCP/IP, which is needed to talk to a modern Mac because the last several versions of Mac OS X no longer support AppleTalk.

So, bottom line, the easiest answer is a SCSI Ethernet interface. You’re on your own with brand recommendations, though — I’m a Canuck in the northwestern United States and have no clue what’s available Over There.
5 Hardware / Well, don’t keep us in suspense!

Do they all still work? This could be a great help if they do.
6 Off Topic Discussion / Seattle Retro-Computing Soc. meets 9/17
September 13, 2011, 04:35
Come one, come all, to the Seattle Retro-Computing Society's monthly
meeting, on Saturday, September 17th, 2011!

Do you do any of the following with old computers near Seattle?

   + Use, collect, and/or restore them
   + Play games on them
   + Write programs for them
   + Develop new hardware for them
   + Help other people do any of the above

If your answer was "yes," as I expect it will be if you're reading this
near Seattle, then the SRCS is for you! We exist so you can show off
your awesome stuff, bounce ideas off of fellow enthusiasts, and be
inspired by one another's achievements, plans and aspirations.

No idea is too big or too small, and we're not picky about what flavor
of vintage machine you prefer! Come on down and tell us about it!

The meetings are graciously hosted by the Living Computer Museum, a
relatively new organization which is building a computer museum in
Seattle's SODO neighborhood. There will be refreshments, a Buy-Sell-
Free-Trade table, and enough table space & power to set up anything you
may want to show off!

For further details, please see our newly improved web page at
http://www.seattleretrocomputing.com/ and our mailing list at
http://groups.google.com/group/seattle-retrocomp . Hope to see you
there!

(Please note, we usually meet on the fourth Saturday of each month; we
had to move it up a week this month because of schedule conflicts with
retrocomputing events in other cities.)

7 Operating System / Can 68K Macs not network to OS X?!
November 07, 2009, 06:04
I followed the directions on “System 7 Today” for installing a recent enough version of File Sharing to network with OS X, and discovered that the latest version described in those directions is PowerPC-only — the 68K version stops existing two minor revisions before the version we’re apparently supposed to use. Vexing.

However, unauthorized but still (I believe) technically legal copies of Fetch 3.0.3 remain available on the ’net if you Google for them, so I think I might be able to use FTP as a rather clumsy workaround. Further bulletins as events warrant.

8 Operating System / Ethernet cable
September 25, 2009, 01:05
You also need to make sure you are using a “crossover” type Ethernet cable. If you use one of the normal straight-through kind, intended for connecting to a router or switch, both ends will be trying to talk on the same wires, resulting in “It ain’t workin’ boss!”
9 Hardware / An orphaned oldie: IOTech “MacSCSI 488”
July 25, 2009, 00:11
For GPIB devices, all I have is a MSD-1 single floppy drive (and, of course, my "Fat 40" PET 4032 itself). As far as I know the MacSCSI 488 is designed solely for use by a controlling program on the SCSI side, but I will of course be experimenting with it to see how far I can bend that rule.

My main idea is to use the MacSCSI 488 to control the MSD-1, with the goal of reading and writing Commodore floppies to and from disk images on the Mac. (Direct communication betwixt Mac and PET would be cool; but not, alas, very useful.) Since the Mac (a Classic II with 10MB/500MB/OS 7.6.1) is networked, I will suddenly have a way to get Internet disk images to my Commodore machines (the PET, and a "flat" C128 with some upgrades).
10 Hardware / An orphaned oldie: IOTech “MacSCSI 488”
July 17, 2009, 00:09
This is a device for interfacing Macs to IEEE-488 (GPIB) devices. I bought it so I could hook my Commodore PET to my Classic II. :¬) It was a bargain at $20, considering the original price in 1988 was ~$800!

The only trouble is, it’s SO old no one seems to have drivers or documentation for it. Even if someone did find drivers, I don’t know as they’d work under 7.6.1 (or, for that matter, under System 7 at all!), unless IOTech issued updates. IOTech’s Support department doesn’t have anything even half that old.

At this point I’m assuming I’ll have to write my own software. Not a big deal, considering the PET and its drives would need custom programming anyway, but it would be a lot easier with documentation. Anyone got pointers for me?
