    Testing a 6200

    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...

    Testing a 6200

    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...

    Testing a 6200

    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...

    Testing a 6200

    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...

    Fun with userspace AppleTalk

    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...

    5260/120 issue

    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...

    Fun with userspace AppleTalk

    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...

    If you could bring back classic Mac OS software, what would it be?

    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...

    If you could bring back classic Mac OS software, what would it be?

    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...

    StyleWriterII Paper Feed Fix

    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...

    If you could bring back classic Mac OS software, what would it be?

    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...

    StyleWriterII Paper Feed Fix

    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...

    Getting a PowerBook 1400 Networked

    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!

    Getting a PowerBook 1400 Networked

    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.
