    TV Tuner Solution for LC 5xx ?

    yes, the 630 itself is where you would add the apple video-in card to the shorter brown slot to the left in the photo url below, and then optionally also plug the tv tuner [via ribbon] to that particular card itself to get your tv-in and composite-in needs (I just had to write all of that in...

    Performa 6400 upgrades

    well bibilt this thread suggests that it is plausible but there are some people that say 50mhz is unstable and they have to settle for just 47mhz or so instead. I don't have anything more to add to your post atm btw

    TV Tuner Solution for LC 5xx ?

    well if you don't want to look for a mactv or 630 logic board then .. hmm .. I wonder if anyone else here might know if the current aio's psu could still handle a base-spec (other than for the video kit being added) nubus-based ppc logic board?

    TV Tuner Solution for LC 5xx ?

    hmm well the 550 doesn't support the apple video kit so you would probably have had to look for that uncommon pds-based composite input card (I know there was at least one model I just can't recall any actual details right now..) and use an external tuner box to actually watch anything via that...

    curious regarding gazelle/achemy L2 module recreation purely in theory

    theres some good ones on ebay/etc in the first place so its a moot exercise to ever think of this for real cost-wise but..if for some reason someone was to want to recreate a new one for themselves, would this kind of sram had worked or theres more to the hardware interface than I thought there...

    games that were released with "unrealized coding" left hidden in it?

    very nice website, too easy to lose your entire day in there I imagine! but anyhow I skimmed through the macos list picking out just a few familiar common titles I knew of as well and eventually narrowed it down to these four to share just for humours...

    adding 4mb SGRAM to PowerPC 5500/6500 ... and possible ATi Rage Pro upgrade

    sorry to add to this thread but I was just musing while taking a really good look at this myself.. I mean its just an 'armchair thought' but it looks like the pro/turbo chip does support 8mbytes via just two chips as well..and in that case.. https://datasheet4u.com/pdf-down/E/M/6/EM6-363.pdf...

    games that were released with "unrealized coding" left hidden in it?

    seeing this topic here https://system7today.com/forums/index.php?topic=4148.msg20155 made me think a bit about that for a while before deciding to ask that topic question here.. any games that had something obvious in its ux and/or engine code that could-had-been but was never actually utilized...

    quick pci performa scsiboot question

    I know adaptec was likely thinking of the towers (which obviously are quite different boards in their own rights of course) when they sold their macintosh pci cards but nevertheless it seem like the datasheets for a few different 2900-series all explicitly mention native bootability as far as...

    Refurbished PowerMac 6500 Acting Up. Did I do it?

    @GerrySch don't mind me adding this reply four months later if thats ok .. regarding your M1, I'm not sure if this would actually apply to your problem but the issue is that apple dropped hfs support for good in catalina (before that there was limited read-only support on like I think between...

    quick pci performa scsiboot question

    just asking in general for now but are these systems normally only booting from the onboard scsi without keyboard interaction or if one was willing to bypass the wiring harness itself then could one had natively boot the sole internal hdd from a fastscsi or ultrascsi pci card instead of via the...

    quick gazelle-vs-alchemy graphics question

    just have to wonder (and create a separate thread for that in case this one becomes less than very short you know) but.. in here https://68kmla.org/bb/threads/found-the-50mhz-bus-switch-on-alchemy-5400-6400.48873/page-3#post-551933 is specifically mentioned "The 6500/Gazelle logic board's...
