Hi Josh. I removed the components from the output side, i.e. the end that looks all blotchy. However, they all seem to function as I'd expect based on my multimeter. Caps charge up via the multimeter & I can see that in realtime - they're not shorted. The inductors do the opposite and even the...

From: https://preterhuman.net/macstuff/techpubs-old/hardware/Developer_Notes/Macintosh_CPUs-PPC_Desktop/PPC_5260.pdf Super cheap Performa 14" monitor, like my Performa 400 I guess.

LOL! Well, compilers might do those things too. It should be possible for a compiler (or human) to code shorter for '020, because it's a strict superset and some of the addressing modes require wasting a register on an '000 for intermediate calculations. There we go! The big differences, from...

It's mostly scheduling rules that change. Unified vs Harvard caches make a difference too, because e.g, a Harvard cache can trade increased data cache misses for increased instruction cache hits. That is, if code exhibits more locality, but data doesn't, then a Harvard cache might win, because...

Thanks, I've read it again. PowerPC had a lot of different microarchitecture choices, which can significantly affect performance in conjunction with a complete system design. The PPC603 is significantly different to the PPC601. The most basic differences (apart from the support for POWER...

So, if @noglin pops up on this thread, then they probably have the best insight. Sounds plausible. I thought I was going to find a 68040 bus signal diagram here: https://www.taylordesign.net/downloads/references/PowerMac5200-6200.pdf And I'm sure I've seen it before, but I couldn't find it...

Reading this now :-) ! Since @noglin is a P5200 fan, I thought I'd notify them here! OK, you mention Noglin later. Based on my analysis of disk partitions on my PB1400c, as standard it will come with the 68K IDE driver, but Mac OS 8.1 and later will install the PPC driver (on a different driver...

Yet, I still don't understand. Assuming I install Netatalk on my Raspberry PI3, what's the use-cases? Connecting up my PB1400c via ethernet to the PI3's ethernet? Then they can both chat on AppleTalk? Or, e.g. all the ethernet devices etc I can see on the PI3 are visible on the PB1400c? Or, e.g...

What puzzled me most about the 5260 was that the display resolution seemed to be limited to 640x480. Was that really true? I was almost on the cusp of buying one in late 1996, actually at the Apple Reseller at Manchester Uni when I discovered this and so I bailed out. My ideal PowerMac was going...

OK, just to remind me about Netatalk. Let's say I have my MacMini Raspberry PI 3 WIFI and my PowerBook 1400c (+AirTalk). Is Netatalk the right way to get me to: PB1400c <---[LocalTalkCable]---> Serial: PI3 ? PB1400c <--->AirTalk )))) (((((Wifi <---> PI3? PB1400c <--->AirTalk )))) (((((Wifi...

There's a massive temptation for developers to begin with a contemporary wish list of functionality and then spend years and years in Alpha & Beta while their project goals shift to meet moving targets. Instead, I figure the 'easiest' way to approach this, IMHO (and here I'm assuming that we're...

This is mostly true for me too, being of the 1984-Big Brother ad era of Mac user, I strongly advocate Macs and try to avoid using Windows. I've never bought a PC; and the 3 hand-me-down PCs that have come my way have been turned into Linux PCs. Unfortunately, nearly all my workplaces have been...

Pretty good. I removed the PCBs from both. You can see that on the faulty one there's a lot of discolouration on the output side. In fact it's possible to see an indication of the issue on the front from the earlier pictures, because D6 is corroded on the faulty one: So, now I think I know...

Yes, I really loved WindowShade - I have it on all my System 7.1 installs. But to answer the OP question, my preference would be for ClarisWorks, probably CW3 or 4 before it all got a bit clunky. The ease of use for combining word processed documents with spreadsheets, graphics or painting was...

So, I've worked out that the second SW2's PSU is faulty, because when I wire up the first SW2's PSU to the second's logic board, the second SW2 powers on. Here's the good one (full size, sorry for any slow download): And here's the faulty one (again, sorry for any slow download): It's not the...

My PB5300 had a combo video/ethernet internal card, but I never used the Ethernet. It was great to have the extra video as I could hook it up to my Sony 15" and get an amazing 800x600 resolution in colour, given that the PB5300 was mono... and only 100MHz!

You also need to check if your card is compatible with the version of Mac OS you have. The same is true for ordinary pcmcia Ethernet cards.

Next update: That SW II also works with the fix! So I can sell at least one of them!

The rubber band approach kinda worked to begin with, but then failed. At best it only worked when multiple sheets were in the feeder. However, I (or the chap who gave me the StyleWriters) had the idea of using finger sections from Marigold™ gloves. I finally managed to test it today and so far...
