  1. One related question for you gentlemen... That Mac was either a 128k or 512k with the original 64k ROMs. Was there a word processor or another application that could put text on the screen like that without any menu bar, filling the entire screen? It probably was a custom piece of software specially made for that demo, but I'm just curious if there is an application program that could run that early System software and hide the menubar.
  2. When Steve Jobs introduced the Macintosh 128k on stage for the first time, there was a voice synthesizer scene where it said, "Hello, I'm Macintosh. It sure is great to get out of that bag." What font was used for that? It isn't Chicago, and it's too thick to be New York.
  3. Sorry to hear about the broken tab. Except for that fundamental design flaw, it's really a great external HDD enclosure. Look like you have a Miniscribe 5.25" drive in there -- small, slow, loud and now unreliable. There are still some 3.5" 50pin replacements sold on EBAY and other places around the net like MacPalace: https://www.macpalace.com/st34572n-seagate-st34572n-43gb-7200-rpm-ultra-scsi-35-inch-low-profile-10-inch-hard-disk-drive.html I have a 4.5GB IBM DGHS in my enclosure, partitioned so I can use it even with System 6. System Picker let's me switch from 6.0.8 to 7.1 to 7.5.5 (even 7.6 and OS 8.1 with the appropriate ROM). I prefer to keep my drive inside the HD20SC rather than inside my SE/30 to reduce heat and power consumption in the SE/30.

    Apple TechStep Overview Video

    Thank you for making time to do those tests and for sharing, Jeremy! Does the SE and/or Classic have any non-Apple upgrades (upgrades other than memory)? The presence of such could explain the TechStep errors, and that is why I covered that in my video. Most tests pass on my SE/30 with upgrades but not all.
  5. Thanks. Take it slow so you don't crack the plastic tabs shown in my video. And after opening, if you find you have a 5.25" drive (loud and slow, and probably not reliable anymore either), you can swap that out for a more modern 3.5" drive, but it will need to be SCSI. You could opt for a SCIS2SD too, although why you'd want it in such a large case is anyone's guess. But I believe SCSI2SD can use power from the SCSI connector, eliminating the need for the power supply inside the 20SC. Anyway, let me know how it goes!

    Will one of you TechStep owners please test your TechStep on a non-IIci Mac? For example, on a Mac II or IIx or Classic (with the correct TechStep ROM module, of course). I'm curious how many have trouble getting the TechStep to enter Test Mode. Thanks.

    So you don’t get the Sad Mac and error code with your TechStep like shown in my video? (At first try, my SE/30 booted normally with the TechStep attached and powered and attempting to enter Test Mode; but after pressing the Programmer’s Switch, I got the sad Mac and then my TechStep showed it was finally connected. That is correct for the SE/30, but I don’t know if that holds true for the IIci.
  8. You mean, "why did two people dare to briefly mention the SE/30 in this thread"? The answer to that is: "because people were talking about the Physical Size of the SEASONIC." Superjer2000, who was one of the people who inspired me to do my own SE/30 PSU mode with the SEASONIC, merely mentioned that he used it in his other mods which included the SE/30, and I followed up with a comment to show just how small it is, which is seen in my video. In other words, we established how small the SEASONIC is -- the size of which is relevant to modding any other PSU. Now that has been established, there need be no further discussion on compact Macs, seeing this thread is indeed about the "Mac IIcx/IIci/IIsi/IIvx/IIvi, Quadra 650/700/800, Performa 600, PM 7100" exclusively.
  9. That SEASONIC is small enough to fit even inside the PSU metal case used in an SE or SE/30, as shown in my video here: But bear in mind the SEASONIC has a fan. The stock SONY and ASTEC PSUs had no fan, so when the SEASONIC fan kicks in, you will hear it, especially if you have a SCSI2SD instead of a spinning platter HDD, and even more so if you have replaced the SE/30 fan for a quieter one. It's not loud by any means, but it may be a new sound that annoys some people.

    Thank you, Crutch! I'm very tempted to fill it out and mail it!

    Modern PSU for the SE/30

    -12V is rated at 0.5A for good reason. Keep in mind when making measurements that you won't be able to measure every possible current draw on that line. Any replacement PSU should be rated 0.5A or higher on -12V.

    Does your SE have a boxer fan or the cylindrical squirrel cage? I unfortunately only have compact Macs with boxer fans, so I cannot show a squirrel cage fan in action. I can only say they need to be replaced by boxer fans. Even so, it would be nice to have one so I could show that replacement procedure in more detail. Thank you for your feedback.

    I certainly appreciate those kind sentiments, thank you! Not to get too off topic but.. I was thinking about doing a new video that looks at replacement fans for the SE/30 & SE since I've been doing a lot of testing lately. But that would probably be rather boring in comparison to the TechStep video. What do you think? I found that a faster RPM fan can drop temps of the CPU on my accelerator by 12°C in comparison to a lower RPM quiet fan, which is pretty significant. The reason I even considered testing different fans is because after running my SE/30 for an hour with a socketed Daystar PowerCache 50MHz accelerator and Micron Xceed Color30HR PDS video card and grayscale yoke adapter, the machine gets very warm to the touch on the top, and when I pull off the case, even the metal frame is quite hot. So while we always think a quieter fan is better, with it comes to accelerated machines, a bit noisier fan may be needed to ensure longer component life. This is especially important since the chips on these accelerators don't even have heatsinks, and the socketed PowerCache doesn't have the clearance under the bottom frame to add one. All you have to cool those chips is the main fan.

    Thank you for your kind remarks, Alex. I uploaded disk images of the two included floppies, as well as all the Apple Technical Info Library documents I could find on a 1997 Apple Service Source CD-ROM, and uploaded those as two separate archives to the following 3 locations: https://archive.org/details/techstep http://macintoshgarden.org/apps/apple-techstep-software https://www.macintoshrepository.org/25829-apple-techstep-software I want to know how to get the software into Software Library: Macintosh because that offers online emulation. I've asked several people, but so far no one has given me any kind of reply. Baffling! I've not had time yet to scan the printed documentation. But the Hypercard stack included on one of the floppies really does contain most of what you need to know. I will add the scans at some point.
