Personally I'd just check it all over and keep it as it is, because it's an early Mac that's much more useful than a 128K. Maybe you'll find a spare 128K motherboard and keep it close to this for a quick switch over for the prestige, but those upgrades are useful.

Clean the RAM slots, and open her up and see if the caps have bulged (common failure)

The Radeon 7500 "Mac edition" was a tried and true upgrade for G4 Cubes for years, certainly wasn't much better than the stock Rage 128 for gaming but made OS X a lot snappier. If your PC flashed 9250 works well, I'd go for it but it will be similar in performance to the older Radeon cards. PC...

Source: years of searching "sonnet" on eBay and coming across these unpopulated boards sold at a fraction of this price. I'm guessing they have hundreds of 'em.

Those unpopulated boards have been on eBay for years, but used to be sold as just that … not prototypes which of course jacks up the price.

@nathall I can sense the words that passed your lips when you were here :). Good you got it fixed. Still haven't done the upgrades as been sick. The new cache card is also very difficult to fit and will likely require additional soldering so the machine pins line up (3 x rows). For removal in...

Quicksilvers are great desktops, if it's a good clean unit and working well I wouldn't bother too much about specs. Once you get one good G4 tower I often find you source crappy parts units for local pickup cheap which might have a better CPU or something you're looking for.

Agreed +1 why bother engaging with the seller again when they were clearly out for a scam/sad story. AI descriptions put in text, not quantities in other fields.

There you go - it looked so sketchy I thought it was non factory! 12mhz I’ll be more than happy with, 6mhz it was pretty good

Didn't look closely enough, the original GALs are: TWGS1A-1 TWGS2A-1 Reactive micro ships upgrade GALs capable of overclocking: https://www.reactivemicro.com/product/transwarp-gs-highspeed-upgrade-gal-set/ I'm not expecting massive gains noting early revision but hoping for 12 - 13Mhz boost...

Check the PSU ... voltages on when it works vs. lifeless. There are ATX or pico ITX mods here if the PSU is failing non-destructive mods. Caps yes would need replacement on the motherboard (am yet to do graphics cards but no reason why apart from being lucky so far), but if failing they...

As in output quality, noise? No. Check the trading forums with the likes of Bolle et al that will post up SE/30 compatible 68040 accelerators at random times when parts are available, but they usually sell out within a couple of days.

Thanks for the tips am very conscious of not wanting to break parts when upgrading (Reactive micro purchased new cache, GALs, CPU and crystal). The card is marked 2189 presume means made ~ middle 1989 and came with the 32K cache module but oddly a 25Mhz crystal only running at 6.25Mhz. GALS...

Hi, I’m souping up an early stock Transwarp GS accelerator to hopeful 12-13Mhz. Part of the process is to upgrade the WD65C816 CPU to a later revision. How do you get it out? I can’t see clips on the top frame, there are two large holes on either corner I thought you maybe insert something to...

Yes Classic II - later revision board (that doesn’t have the 4 X ROMs in line) The crusty stuff is dirt/corrosion and needs a very deep clean

I’m so in for V2 with the Takky DOS compatible refresh compatibility!

TAM brightness setting was always controlled by physical buttons not software. Did it work before you took it apart? There is a probably a cable somewhere that needs connecting perhaps to the DAV board between the LCD motherboard video output - follow the mess of cables 😀

Glad it's working - I've had similar issues with my TAM after some upgrades resulting in a "dead" Mac, but disconnecting all and letting it think it always gets back. Still looks like a single tantalum cap has blown (as they do) and once the soot is removed other components look OK. There used...

I've had an LC630 overclocked to 40Mhz for years, noting the onboard video performance is a bit average I can't see pushing everything to 45Mhz would be amazingly noticeable

Oh dear - it's just the tantalum capacitor by all appearances - looks like the same markings at the one opposite, 10V 100uF (at a guess). I wouldn't think you'd need it for boot - the 6500 it is based off also has a separate TV tuner box and not essetial. I'd pull the PRAM battery press the...
