    601 processor replacement experiments

    I know the L2 interface is impossible :sadmac: 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...

    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...

    Unusual questions about PDS G3 upgrades for 6/7/8100

    @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...

    Unusual questions about PDS G3 upgrades for 6/7/8100

    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...

    Unusual questions about PDS G3 upgrades for 6/7/8100

    @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!

    Unusual questions about PDS G3 upgrades for 6/7/8100

    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...

    Unusual questions about PDS G3 upgrades for 6/7/8100

    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...

    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...

    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...

    FireGL X3 cross-flashing to AGP 4x x800 XT?

    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...

    Recently acquired Supermac card for my IIci

    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.

    Recently acquired Supermac card for my IIci

    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.

    Recently acquired Supermac card for my IIci

    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...

    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...
