    601 processor replacement experiments

    I know the L2 interface is impossible It was just to give my version of the "So what should give better performance, 1M clock divided backside L2 or 512K of on die (frontside?) L2? " in one of your previous posts. By mentionning the L1 I just meant the branch predictor and data caching mechanism will do their job and try to utilize the L2 and main memory, no matter how slow, the right way. And by "less frontside bus transactions" I meant less stalls from cache misses (not caching itself) since the bigger and heavier the dictionary, the more entries you can look up before having to boot up your sluggish PC to google what you're looking for. A while ago I switched daily drivers from a Quicksilver G4 with 2x 1.6ghz 7447 w/ 512kb on-chip L2 to an MDD with 2 x 1.5ghz 7455 w/ 256kb on-chip L2 and 2mb L3 and I didn't know L3 made such a damn difference at times it feels like night and day

    601 processor replacement experiments

    I'm not wanting to be a disturbance here; In fact I'm just keeping watch out of curiosity. I believe more external backside cache (as opposite to less, faster on-chip) would be a bigger help, given a slow frontside bus with even slower memory will disproportionately bottleneck a (300mhz+?) chip at each FSB transaction. To me the trick should be to avoid as many FSB transactions as they're the worst case scenario (even more here). More backside cache is likelier to do so, and the L1 will still do its job..
  3. @gpbonneau the lower-profile newertech card in the picture is the kind of newertech upgrade that could be a candidate for use in my 7100 (with the sonnet pds ribbon cable). I expect the clock multiplier is the only thing that prevents it from working in a 7100/8100 but, needless to say, mixing the sonnet ribbon cable with such a card to connect the HPV is way too scary to try; especially when I have no next to no spare parts (a single 7100/80 mainboard and a 2MB HPV). Possibly that may change if I find some theory to back up what would happen? @Trash80toHP_Mini On macsales.com around 2010 there were a dozen of these crescendo G4 upgrades still available at or less $200 IIRC. So sonnet actually shipped them. That said, what was a great shame at the time, they were completely incompatible with connectix virtual pc. I don't know how popular they have been, given they hadn't sold out in 2010. Fortissimo G3 400/500mhz upgrades are truly the real deal for 6/7/8100 machines. I'm seriously considering to look for a sonnet 400/500mhz G3 upgrade instead of a newertech one. No need for a new card connector, and even in the case it still wouldn't work with the atto SEIV, that would make for a nice upgrade (260mhz to 400 or 500). (good luck to myself finding one)
  4. Took some time to respond, sorry. I believe my card is an older version, yes. It has a purple heatsink, though I'm not sure that means anything. It was bought around 1999-2000 (dropped the 7100 board in a centris 650 case I had about a year before that) and has always been used in the 7100 since then. It was the cheapest model that came with 1MB backside cache at the time. And I'd say it's pretty much stable, no freezes as long as I don't access a file system via the SEIV at the same time the G3 is running. My current drive is connected in fast-wide mode from an external scsi enclosure and it works like a charm with sonnet processor upgrade disabled. It really doesn't look like an indirect stability issue to me. Still, fair enough, this machine wouldn't suffer from a mainboard checkup, dust out and thermal grease replacement; it's been a while.
  5. @gpbonneau Yes that's still of help, It clarifies at least a few things and I didn't know the ribbon cable was soldered to the newertech card. Thanks for the info!
  6. I'm using 2.0rc2. Mind telling me if the SiliconExpress control panel detects your card in case you're using the same firmware version? For me it only does when 1.65 is in use, though with 1.65 disk throughput goes from 15MB/s to 5-6MB/s thus defeats the purpose of the card. It doesn't work with the G3 either. What crescendo/fortissimo G3 do you have exactly?
  7. Not too long ago I returned on my PM 7100/80, which right now has a sonnet PDS g3 260/1M, a 4MB HPV card connected via the g3 card's ribbon cable, and one nubus slot used by an Atto SiliconExpress IV. For a few reasons (among others, using a disk attached to the SEIV at the same time the G3 is enabled freezes the machine without exception) I'm looking for a comparable newertech G3 upgrade. G3 upgrades sales seem to become sparse, sort of. There's a couple listings on ebay that are not reasonable to me, price-wise. While I'm unsure getting a newertech upgrade would make things any better, I have a few concerns I feel like posting here hoping it eases up deciding what to do. - Can anyone confirm newertech PDS cards have fixed CPU:FSB clock ratio? Sonnet chooses settings in software, and perhaps fixed/jumper-set bus ratio would help with some quirks I'm experiencing. - As far as I know, 6100, 7100 and 8100 all have the same memory architecture. So that should mean NewerTech's G3 upgrades exclusive to the 6100 are this way because the card has a CPU:FSB ratio too high for the CPU to work with a 8100/80, 7100/80 or 8100/110. So if such a card gets its PLL setting to something lower, it should just work. It would give me more options. Is there something more I should consider for this? - Did anyone try using sonnet's ribbon cable to connect an HPV/AV card to a NewerTech upgrade? Did it work? Finding a Newertech G3 card WITH the ribbon cable raises the bar a lot. I'm not sure I'll have answers for the last two, but I still hope. Thanks!

    SEIV for my IIci?

    If the card isn't bootable, I am a bit confused for the fact I managed to boot on the drive connected to it. I gave up on getting it to work on my IIci after another week of unsuccessful attempts. At least my Power Macintosh can use it.

    SEIV for my IIci?

    I tried on 7.5 on my powermac and 7.1 on my IIci. 7.5 works fine. I just thought about something. Can a mac IIci use two scsi buses at once? The only thing i havent mentionned is that I boot from my onboard scsi while the card is on. I'm going to try it only with a drive on the SEIV. Atto never mentionned in their manuals that you could use both buses. The only instructions are for using the same drive with the Silicon Express IV.

    SEIV for my IIci?

    I boughta pair of Atto SEIV on ebay about half a month ago. My first goal was to get one of those "monsters" to work with my mac IIci which boots mac OS 8.1 (mostly) on a large 72 gb Fujitsu 10000rpm ultrascsi drive. When they shipped: first thing should have known before was that those two cards weren't always well-treated. I couldn't see it on the only picture on the listing, but four or five pins on a chip for each card were bent and causing short-circuit. Since I wanted these cards so bad, I spent (almost 2hrs) to straighten them up correctly with a sharp blade. What a waste. I put the first one in my IIci -- On bootup, unimplemented trap occurs before inits start to load. Same for the second one. To make sure that they were in working state, I put both of them separately in my Power Macintosh 7100 with its Crescendo G3 disabled. Both of them didn't crash, were able to see any hard drive I would connect to it, and were bootable after updating the firmware to 1.6.5 (I didn't try to boot before doing it). I also flashed one with version 2.1rc2 and tried it on both machines; I had problems to boot from it using my Powermac, and my IIci wouldn't see any hard drive at all, but boots, though both see the controller. I gathered the following three informations about the behaviour of both cards during last week: • My IIci won't detect the card at all when in 24-bit mode, so zapping PRAM can get it to boot anyway when the 1.6.5 one is in; • Depending on the disk driver, trying to boot on the controller card's drive from my powermac may fail and prevent Mac os from seeing any partition on it (a reboot with another boot drive set is necessary to see them again); • (Found randomly) Holding cmd-opt.-shift-backspace RIGHT AFTER seeing happy mac on my IIci makes it boot and detect the card correctly, but no hard drive on the bus is detected. I really am out of ideas right now, what's going on? If someone can help me out in any way, It would be greatly appreciated. I am sure both cards are working, since they didn't make my 7100 crash.
  11. I read that has already been done. Has anyone given it a try? I bought an ATI FireGL X3 on Ebay for about $20 CAD to do so. Else than not being able to boot OS 9, would there be any other problem with using it on a 2001 QS? Will the screen show up only after booting? If anyone has anything to share about their experiences with this, please tell me. Thanks
  12. Makes sense to me. At least I can get a nice 1024x768 in 32-bit colors and switch between sizes. What I was hoping for.
  13. I don't have one for now. I should try, though! I changed my mind about recapping, since they all are surface-mount ceramic capacitors. At least I retried my sony 17" and horizontal bars are less visible and less frequent. The other problem seems to be gone.
  14. So i bought that Supermac thunder /24 (rom v3.00) to get better screen resolutions and to switch between them without having to play on the adapter switches. Pulled the 8•24 gc from my mac IIci and put the supermac instead. Works fine and has good image quality, except for the horizontal waves that show up occasionnally and half of the screen that sometimes move for a tick. I tried two other lcd displays, other apple multisync cables, reslotted it once and plugged it directly to the display(I use a display switcher). The waves are still showing up and the screen still moves sometimes. Then I started wondering 'Could the problem be due to any component on the supermac's board?' So I ask here to see if anyone knows any related problem that can be fixed for the Supermac, or what component could it be. I will try cleaning contacts first. I will maybe try recapping after if this can be my solution. Any answer will be appreciated.

    My attempt to develop a cross-assembler

    Update: Since my program wasn't working, I reupload it. This time, it includes equates, arithmetical expression processing for immediate data and more. Also, I made it as crash-proof as possible: I tried changing an 1.4 mb image's file type into TEXT and processing it with 2mb of RAM. It didn't crash. It can run with 32kb of ram if the file isn't too big, although I suggest at least 64kb. It is tested and runs on system 6.x, 7.x, 8.x, 9.0.4, and should run on 5.x and earlier. It also is Classic-compatible. The only problem is that it won't quit correctly on Mac Os 9.1 and 9.2, and results in an address error. If someone would look at my source code and give me some hint, I would greatly appreciate it. Thanks to anyone who will try it out or look at my source code! If anything's wrong with my program, I'd also like to know. ASMac18 Project.zip
