    68K (no Mac) Designs OK?

    68030 does have a lot going for it in terms of development platform, are they still making embedded system versions?

    How to change screen resolution? (LCIII, System 7.1)

    What G said. Yes, in 7.1 that would be the "Monitors and Sound" Control Panel IIRC? In "Monitors and Sound" and the later "Monitors" Control panels there's a menu choice for "Recommend Resolutions" and "All Resolutions" listings. Many times you can find something that will work much better under "All Resolution" than under Apple's recommendations if you have a more capable (later, multisync) monitor from Apple or just about anything from any Display Vendor outside of Apple. From the sound of it you'll be wanting to reference gamba's VIDEO: CPU & Monitor Matrix to see what's possible with the combination you have on hand or can improve upon in terms of color depth. The VIDEO: Card & Monitor Matrix will be more helpful in terms of resolutions. Everything above the "Multisync Divide" is a dead end in terms of getting a better resolution. Again, as G said it depends upon the capabilities of your display,. From your description, it sounds very much like you're locked into a single resolution on one of Apple's early fixed frequency monitors listed above the divide.

    68K (no Mac) Designs OK?

    Very interested in your project, what machines besides Mac and Amiga were in the 68000 family, workstations of any kind? We've got Lisa on the 68000 list, it seems someone has streamlined the logic board's design and produced(?) compatible replacement boards: http://vintagemicros.com/catalog/lisa-board-from-sapient-technologies-p-296.html Curious about your OS choice/development plans?

    Got any LC thru LC475/Q605 and TattleTech handy?

    Thanks much, not what I was hoping for, but it's what I expected. Interesting that IIsi Video shows up at $0E when it's based on the same RBV/MDU controller setup as the IIci? IIci Video shows up at $00, no? From the IIci DevNote is sounds like the Vampire Video setup of the IIsi was lamed by buffering only the first 1MB of Bank A in terms ersatz video memory, but superior to that of the IIci in terms of of avoiding the performance penalty of the IIci setup. The same MDU/RBV combo buffers/sucks the blood out of Bank A in its entirety during video operations in the IIci. The more pixels a/o more depth of color slows IIci memory operations with every increase in demand. Can anyone confirm that IIci internal video shows up as part of the motherboard at $00?

    Carrera040 in Macintosh IIsi

    What kind of adapter are you using?

    Radius PowerView

    @360alaska might have been playing with one of the 5300s at the time? Looks like the hinge cover from one. I'm sure I can lay my hands on the box soon enough, in the meantime I've gotta get DropStuff working on something with a floppy drive.

    Macintosh Plus Internal Hard Drive *Mod*

    Booboo probably, I was asking for feedback like this on the layout way back then. In the meantime, someone (Alaska?) developed and was selling a proven design. Dunno how my design stacks up on the kluge scale by comparison, likely much worse as this graphic was a feasibility study in terms of form factor.

    Carrera040 Info / Hacking Thread

    With all the recent Daystar Digital Turbo601 action a thought occurred. @toples50 I was wondering if your IIsi adapter for Turbo601 had been tried with Carrera O4O in the SE/30 yet?

    Daystar Universal PowerCache P33 in SE/30

    It is absolutely POSITIVELY NOT 1:1 and you'd need to do the IIci Cache Slot adaptation in cable. Bolle's only saying you don't need the GAL. Von's cable extender hack is exactly what I was talking about, you'd need to switch almost every (every?) wire around from motherboard connector to PowerCache/Turbo 040 connector. @Bolle If you wire up one of your adapters to bypass the logic and its latency, will more of your SE/30 boards support multiple cards?

    Daystar Universal PowerCache P33 in SE/30

    Someone used M-F breadboard wires as a Radius Color Pivot II/IIsi card riser in the SE/30 PDS. You could do the IIci Cache Slot adaptation with those I suppose. I've picked up a few M-F NuBus length rbbon cable assemblies a while back, but never saw them again on eBay.

    Another Turbo 601 / SE/30 Failure Report

    Not even close to NuBus in SE/30! A few of us are chipping away at it here and there as time allows. nickpunt scored an adapter that could have been a big break to get things rolling. That came to a screeching halt when a GAL on it was found to be dead. BTW, I can't really develop stuff in the skunkworks, I just line up interesting information for the magicians. The Radius Rocket is the only processor upgrade I can think of offhand that needs drivers/software at startup. It does a double boot sequence, primarily for loading the hosts ROM into onboard RAM. A processor upgrade or accelerator pretty much needs everything required to boot a Mac in its own ROM. There are a few which do require the host to boot and hand over control. which would involve a driver. Recent thread with related info:
  12. OK, I come up with crazy ideas for all kinds of crap, most of 'em don't pan out and some bomb out completely like this one, but every once in a while I set some wheels to turning. Learning is good. Thank you! @Cory5412 about that "VGA Adapter" moniker. IIRC I've got some in packages that say "Macintosh Video Adapter." I'll have to check, that would be a better term that's more in tune with the MacVDO manual I posted, but many say Mac to VGA adapter or something similar like the "Belkin Mac-VGA" product manuals someone posted. What a mess.
  13. I believe you! Got it, sort of, but "pitch" staying the same appears to conflict with this statement. You appear to be saying the pitch of the pixel changes? ISTR something about applying filters before and after using a delay to keep a signal consistent, but too tired to read it over again ATM. Do you want the wave form to be the same if you're trying to match dot clock frequencies in a B&W video signal stream? It was a case of high or low on the dot and phosphor persistence in the CRT took up the slack along with brightness and contrast controls to get an acceptable image . . . did it matter how long or short the spike might be so long as it's centered on the dot? Apologies, too tired to think very straight ATM, but still curious.
  14. My plumbing analogies always leak. The bucket brigade think threw me for a loop, one of the images I'm playing with is a gear driven sprinkler head.
  15. He, I'm still trying to piece that post together. Quoting across a page break like that is maddening. edit: just signed off on the blather above, fire away!
