Broken Circuit (kjelstroem Games) Mac Os Catalina

Apple has determined that a small percentage of the keyboards in certain MacBook, MacBook Air, and MacBook Pro models may exhibit one or more of the following behaviors:

Our monthly Mac games release column aims to put the latest and greatest titles on your radar, but if you haven’t kept close tabs on Steam, the Mac App Store, or other storefronts this year. To do this, go to the Utilities button on the upper OS X bar as pictured below. Then go to Disk Utilities. The disk utility will come up. Click on your hard drive (Not any partitions you may have, see below - its in the right hand column) and then click the erase tab.

Letters or characters repeat unexpectedly
Letters or characters do not appear
Key(s) feel 'sticky' or do not respond in a consistent manner

Apple or an Apple Authorized Service Provider will service eligible MacBook, MacBook Air, and MacBook Pro keyboards, free of charge. The type of service will be determined after the keyboard is examined and may involve the replacement of one or more keys or the whole keyboard.

To identify your computer's model and to see if it is eligible for this program, choose Apple () menu > About This Mac. Eligible models are listed below.

Note: No other Mac notebook models are part of this program.

Please choose one of the options below for service. Your Mac notebook will be examined prior to any service to verify that it is eligible for this program.

The type of service will be determined after the keyboard is examined and may involve the replacement of one or more keys or the whole keyboard. The service turn-around time may vary depending upon the type of service and availability of replacement parts.

Find an Apple Authorized Service Provider.
Make an appointment at an Apple Retail Store.
Mail in your device to the Apple Repair Center.

To prepare your unit for service, please backup your data.

Note: If your MacBook, MacBook Air, or MacBook Pro has any damage which impairs the service, that issue will need to be repaired first. In some cases, there may be a cost associated with the repair.

This worldwide Apple program does not extend the standard warranty coverage of your Mac notebook.

If you believe your Mac notebook was affected by this issue, and you paid to have your keyboard repaired, you can contact Apple about a refund.

The program covers eligible MacBook, MacBook Air, and MacBook Pro models for 4 years after the first retail sale of the unit.

Rolled out in January 1989, the SE/30 was the first compact Mac to come standard with the FDHD 1.4 MB floppy drive (a.k.a. SuperDrive) and support more than 4 MB of RAM. It was essentially a IIx in an SE case.

Although advertised as a 32-bit computer, the SE/30 ROMs were “dirty,” containing some 24-bit code, meaning it could not run 32-bit applications without new ROMs (which Apple never produced) or a software patch. To use the SE/30 in 32-bit mode, you need a free copy of Mode32 from Apple (search the page for “mode32”). (You only need 32-bit addressing if you have more than 8 MB of memory.)

The SE/30 offered the power of the IIx in a minimal footprint configuration. With the built-in 9″ screen, it was a popular network server.

The SE/30 has color QuickDraw built in, so it can be used to surf the Web. However, it requires a video card, such as the discontinued Micron Xceed, to display anything beyond black and white.

Did you know the SE/30 could display grays on the internal monitor? If you can get your hands on the Micron Xceed video card, it supports 8-bit video on an external monitor – or on the internal screen when no external monitor is attached. These cards are rare and highly valued.

Aura Systems made ScuzzyGraph II, a SCSI peripheral that provided 8-color video for people who didn’t want to buy (or couldn’t afford) a Mac II. 1989 cost was $995 to $2,495, depending on resolution.

The SE/30 can handle as large a 3.5″ half-height SCSI hard drive as you can find, another reason it’s long been popular as a server. To remove the hard drive: find the two screws holding the drive bracket in place. They will be facing the rear of the computer and underneath the drive itself. You’ll need a fairly long Phillips screwdriver to reach them – and you’ll need to disconnect the power and data cables before you can get to them. Once the screws are loose, lift the back and it should come out easily.

LEM’s System 6 Group is for anyone using Mac System 6.

There is a ROM SIMM slot on the SE/30 which must be filled with a ROM. Without this ROM, the computer will not function.

We’ve seen several claims that replacing the SE/30’s ROM with a IIsi or IIfx ROM makes the SE/30 32-bit clean and allows use of Mac OS 8.1 (with a lot of fiddling). We are interested in hearing from anyone who has successfully put a IIsi or IIfx ROM into an SE/30 – and whether you got OS 8.1 running or not. (Note that the IIsi ROM is rare; most have the ROM soldered to the motherboard.) Dan Knight, publisher.

After the SE/30, Apple didn’t produce another compact Mac with an expansion slot until the Color Classic in February 1993.

You can convert a non-working compact Mac into a Macquarium. (Please, don’t even think of converting a working one – you can always find someone interested on the Classic Macs or Vintage Macs lists.)
