Guys, I am either doing too much crack cocaine today, or not enough. Actually in my area of the world I guess the tipple of choice is meth, but my parents were dentists so that doesn't seem like a good idea to me. 1. Who mentioned a Plus, ever? Not that it makes any difference but the machine...

I've downloaded it twice from two sources. No dice. I really only want a newer version of MS-Word than the one I currently have. Nothing else matters :)

No. I want to use the bare 6.0.8 image as my base so I'm booting off that. So my SD card has: HD0-OpenRetroSCSI-6.0.8-500M.hda then I add HD1-whatever.hda System boots off HD0 and I expect to see HD1 mount whenever it gets around to it. For example I did this with a blank HD1 image so I could...

I am using the System 6.0.8 boot image linked from the BlueSCSI site as my primary boot. That works fine (and boots in seconds, yay solid state storage). But I want to get some applications into the image. I downloaded MacPack and renamed the vhd to hda. I put the hda on my SD card with an...

I was looking at those just before Christmas actually :) hmmm. Tempting. I'm still maxed at 4MB RAM right?

What's that going to do for me that my DB25 BlueSCSI doesn't already do? I looked at the announcement page for it but ... am not yet excited?

Again, bibles only go so far. You can't trust a guide implicitly because there are an essentiallu infinite number of potential failure modes in any device of moderate complexity. There is not and will never be a complete troubleshooting flowchart that gives you an exact answer - that's not how...

Probing the pins of a driven xtal circuit is always a bit problematic. See those 33pF load caps on the xtal? The scope probe can add as much as 15pF to that, which could be significant. But I would expect to see something stable on XTALOUT since it's the drive pin.

I was so proud of myself yesterday. I wanted the plastic adjustment toolset and I was about to buy one off Amazon, then I went out in my garage to check my Drawer O Tools and I found... the EXACT set I'd just been about to buy again...

Y3 is the RTC 32.768kHz oscillator and won't affect anything startup related. It also does not look damaged to me. That circuit is difficult to probe because the scope adds capacitive loading to the oscillator. But regardless, it is not part of your startup problems, I'd bet dollarpoundbucks on...

I am trying to decide if I want to put something in the PDS slot of my daily driver SE. I currently have a BlueSCSI on it, 4MB RAM, and I use it for writing without distraction. Given that I mostly use MS-Word or equivalent - should I get an Ethernet card, an accelerator or extra RAM? Or a weird...

If you replace the chip and it is still not working, then sterner investigations are called for. Do you have an oscilloscope? One of the most annoying 68000 issues I ever had to debug was a pirate clone of the Robocop arcade game board. (DECO, 68000 based). I eventually traced down the issue to...

They switched because Motorola stops making early access labeled parts once the part goes into full production. There were no more XCs to buy. The difference is chip-specific. Could be nothing at all, just a paperwork thing. In some cases Moto moved to a smaller process node when they went to...

I don't recall seeing XC68000s (even the Lisa boards I've seen had MC68000s) but for sure I've seen plenty of XC030 and XC040 CPUs in Apple gear. I, too, have not heard of any systemic problems with the parts, it's just an interesting historical note.
