    A very late 040

    I've not recapped my Q630 - yet - I feel the PSU will fail very soon so glad of recent efforts in implementing an ATX solution.

    powerbook 5300cs

    Next in line of repairs, I've got three PB100 displays to recap - not looking forward to it as the chance of killing it is higher. Re: 3400c display, I've had several of these and display quality varies wildly - the "best" one I have far exceed my TAMs (same) LCD, others have been really shoddy.

    Bondi Clamshell!

    You can pick up USB extension cables from anywhere to have the USB drive dangling off it. Congrats on getting it running, the Clamshell is a great piece of design.
  4. Try another smaller CF card (1-4GB) and make the first boot partition < 2GB. It’s probably nothing to do with the adapter, but the early IDE implementation of the Q630 being incompatible with the card. I tried in vain with a 16GB Sandisk extreme in my Q630, gave up and ended up putting in a nice quiet 2.5” 60GB IDE inside.

    PB 100 recap woes

    Spent a nice Sunday afternoon with some success resurrecting three PowerBook 100s - all were recapped a couple of years ago, with the cleanest and best looking board booting but causing a "blacklit screen" as noted above. I went back to these as the tantalum caps and electrolytic caps I had used were of dubious quality and felt I hadn't cleaned the cap goo off well enough previously. And also, I just really wanted to see a working PB100 after three duds lying around - Powerbook 100 # 1 - the best board - checked all caps (good), found I didn't replace the 100uF/10V capacitors - did so - same as before chime, boot and "blacklit screen"; tested the other to LCDs with same effect. I suspect the issue lies in one of the three transistors in the middle of the board (one had a clip on it that extends to touch the keyboard when down as a basic heatsink). But that's where my electronics experience stops. - PowerBook 100 # 2 - cleaned all cap regions with IPA and cotton bud, replaced and tested some dubious tantalum caps (yep, three were the wrong way around), fixed a broken pad - success, booting well to desktop - PowerBook 100 # 3 - cleaned all cap regions with IPA and cotton bud, replaced and tested some dubious tantalum caps - success, booting well to desktop So it was the best pristine unit I couldn't resurrect but two others came up well which was pleasing! Now to the LCDs - all three have an small odd pink patch on each, looking a bit like a fungal growth/moisture ingress or LCD is damaged. One recapped has good contrast and brightness, the other two LCDs untouched have poor contrast and brightness. I'll donate one LCD to experimentation and strip down the LCD layers - it might be the top polarising film that's damaged. JB
  6. Some more observations: - Don't bother installing any System above System 7.1 for RocketWare; System Update 3.0 installs Sound Manager 3.0 which crashes the system even when system sounds are is played. Removing Sound Manager 3.0 from startup sound still crashes. - The QuickColor control panel which detects both Rocket and PrecisionColor graphics card accelerates video considerably - Sound is very poor on the Rocket. You will have the exact same sound issues as if you were running RocketWare over RocketShare. Sounds will not play for any game/program that directly accesses the sound hardware, QuickTime and MIDI based sound is also non functional. So while all games run, it becomes a gamble in what sounds you'll get - for example Marathon I sounds are OK, Marathon II is not! - Performance is of course magnificent, exceeding performance of a Quadra 950, so the card will remain in my IIfx with said issues! At least I can disable it for older applications. JB

    Walkmac

    I like how the base of the unit has a mouse mat! We've all seen keyboards with computers inside (Amiga, C64 etc), why not the mouse mat?

    NeXT Cube and NeXTStation TurboColor

    That's true, I suppose if the battle scars become more of a nuisance or the paint peels more, yes being done professionally would be the way to go. I've a TAM in a similar situation, many a scar but it went through a lot to get to me, however I've replaced what was particularly worn and it's functionally perfect.

    NeXT Cube and NeXTStation TurboColor

    So good! Are you planning restoration of the nicks in the NeXT Cube itself? One of those paint markers might do a quick and dirty job, after that possible reanodising (when the wallet has wings again).
  10. @Mk.558 Thanks, I'm just so pleased this card works - I picked it up from a 68KMLA member years ago and never put it into use. Couldn't find the right machine to match it in. Seems my track record so far resurrecting accelerators is that they don't stand the test of time which you'd expect, like the engine of a highly modified car! My pandemic lockdown tested upgrades like Sonnet G4, Apple 601 PPC card all had issues of late. No, I don't have the SCSI-2 daughter card but would love one. Yes, this one always had a heatsink and I put a small 12V 40mm fan on it, currently sitting in the centre slot as it was blocking the IIfx PSU fan. Doesn't seem to get hot at all. I'll put up pics of it all soon, once I've thrown a pile of software onto it. JB
  11. With these early accelerators you probably don't want to go out of spec too much at all, for all the reasons you've noted. This one has a 68020 12Mhz which must have a 16Mhz crystal, and some sort of "slow" "fast" jumper that might help out on a mild overclock. Of course if I ever get this one working I'll pick up a cheap 68020 25Mhz with requisite crystal and give it a crack. There are some interesting workarounds in modern 68000 accelerators in Amigas that might help our cause in future. @techknight Thank you, I've sourced exact matches from mostly the same seller dealing in vintage NOS ICs for all but the ?? DIP14 package that is a variant of a PALCE16V8H-15PC (Quik30) or PAL16R4BCN (my MACX20), no idea what it is.
  12. The Radius documentation could have been clearer; the card was not supported in a IIfx at all earlier than RocketWare 1.5 so let's see how it fares running natively. A card way ahead of its time in 1991 however with some quirks. The RadiusWare control panel for the PrecisionColour 24X is also detecting the Rocket combined together as "accelerated", it'll be interesting to see any performance boots with it on or off in benchmarks. JB
  13. Coming back to this, for more info the reason the Rocket booted in the IIfx was due to 24-bit addressing being set when the PRAM was reset; kind of useless having an '040 card with only 8MB addressable. Setting 32-bit addressing either running as IIfx or Rocket mode results in a freeze straight after the Radius Rocket logo coming up at startup. A read through the RadiusWare V1.5 documentation reveals an incompatibility between a IIfx and 32MB or above RAM will not allow the Rocket to boot. Note that's 32MB or above - 32MB will not work. That leaves 20MB RAM in the IIfx as the next step down, thankfully I scrounged some modules to get this. I'll play around with RocketWare and see if there are minimal sound and application incompatibilities unlike RocketShare. If it works well, it'll stay and not not I'll try it in another Mac that might utilise it more effectively (might find a Iici, II or IIx one day).
  14. @techknight Thanks so much for posting your Novy30 - can you please reel off what's marked on these two ICs below? Can't quite make them out but appears they are the same. The DIP20 socket on mine has a PAL16R4BCN, and you'd assume same in both however my missing IC is DIP14 ... n00b alert to find equivalent do I look up the datasheet and try to find a DIP14 variant? @Realitystorm Thank you, Novy MAC20X it is - amusingly "documentation is unclear and incomplete" I'll try to find a higher resolution version of the magazine which would reveal more. It appears all sockets are populated, including the crystal.
