Thank you! I updated the details on the endurance challenge with a link to the BBS web page: https://www.retrochallenge.org/2022/09/announcing-retrochallenge-202210.html

Oh, It looks great! So, if you added a forum / area there, everyone could post their updates in the same forum and then somebody could search by user and get just one person's entries,, I think. I will keep in contact with you to make this happen. Thanks!

I am very interested! Is there any sort of internet bridge for the forums there?... Maybe Ill just sign up and check it out. Thanks!

We were going have it in January, but why wait?! We are happy to announce RetroChallenge for the month of October 2022! RetroChallenge 2022/10 Theme Categories We have one theme category for this event: Endurance Challenge. This category will be judged and awarded separately from the standard...

That's a good tip I never knew about! Here I was looking up Apple part numbers! Start with isopropyl alcohol on a Q tip to clean the drive head. Do some searches on this site for troubleshooting info. Those 400K drives are built like tanks, so other than lubrication, I have rarely had problems...

Do note that the contacts on the flyback may be spaced differently, but the plus analog board should have a ring of contacts for either size.

It looks like your 128k still has the original 64K ROM set, despite the RAM upgrade. It was pretty typical to upgrade to the Mac Plus ROMs when doing this upgrade, aligning with cheesestraw's theory that this was an early upgrade (before the Mac Plus arrived). Without knowing the error you are...

Actually, this is a really good price: https://www.ebay.com/itm/184770905497 However, this is for a lower wattage than the HD monitor uses. The ones for your monitor are the 90W which is about $30 on ebay

I can't recommend this, but at least it is an option:

I believe that is for a security lock so people can't steal it, not a data cable. I have the same monitor, and it works fine without anything in there. Great monitor BTW!

RetroChallenge 2021/10 is open for sign ups! Let's Boss This! http://www.retrochallenge.org/2021/08/announcing-retrochallenge-202110.html About RetroChallenge In a nutshell, the RetroChallenge is a loosely disorganised gathering of RetroComputing enthusiasts who collectively do stuff with old...

Hmm. You just said  which made me think we were on very different pages. Anyway, good luck!

NuBus Runs on a 10MHz clock, even on the II. The discussion was about a IIsi NuBus adapter. The Mac II has 4 state machines to keep the system synced up with Nubus. Maybe they are all incorporated into the IIsi NuBus adapter, but I don't see why they would be.

It's open! http://www.retrochallenge.org/

The SE/30's 16MHz bus speed is not right for running 10MHz  NuBus. That's why the 20 MHz IIsi can do NuBus with so little hardware. You would probably need to accelerate the SE/30 to 20 MHz, and lose all of its onboard capabilities (including video and SCSI), or have a whole lot of hardware...

What system is crashing? The Raspberry Pi or the Mac?  What Mac/System/Browser are you using? When you are saying that outside domains are not resolving, I assume that no packets are getting through, not just that DNS isn't working (like it is a symptom, not the actual problem). Some ping tests...

Or spray some WD-40 on the contact points (making sure to not get overspray on the drive head). Work it around, wipe down, and put on some new lithium grease. It saves the effort of having to disassemble.

Sorry, that was vague. I was referring to modifying the I/O to the logic and drive controller in the 800k Drive. So the Sony's 800k drive controller would just work. Hmm, I thought the SmartPort firmware in conjunction with the IWM was used to control the Apple 3.5" drives and the...

My thought was to half the PWM frequency and double the TACH frequency so that the 800k controller would just work.  But I am sure there will be problems with jitter, etc, running it so far out of the specifications. I think I am better off just looking into a modern buffering FIFO (or even a ...
