I love my two NuPower batteries - they are both getting weaker, alas. I keep babying them along.

I assumed it was a power management issue as it won't charge batteries anymore (hasn't for years) but that could of course just be dead batteries! (One of them was a new NuPower Ma…

I would guess it was a power management issue with the software.  Like shutdown every 15 minutes.  It only asked you because you were using it.

Yes , strange. Maybe a virus, there was some : http://lowendmac.com/2015/classic-mac-os-viruses/ Can get them with old downloaded games sometimes. Install Desinfectant.  Happy t…

I booted from a 9.1 CD and it wasn't doing it, so I did a fresh install... and it's ok now. Genuinely confused as to what caused it (~15 years playing with Macs and I've never see…

Have you tried booting from a system cd , see if it does the same ?

I know this isn't a mechanical problem, as I've gone so far as to unplug the power button to see what I can do here. I know the power button works, because it can boot the thing f…

(Elfen you were right, the floppy that I normally put disk tools on had died.  The SCSI CD drive will no longer boot either the c or cs, but I think it may be a termination issue. …

Ok so the 5300c's bus is fine; this is at least partly a drive issue.  The drive in question, with a jumper, spins but isn't recognized.  Without a jumper it spins and shuts down i…

I was going to say, Elfen, if you can clue me in to any factors you think might affect the cards, I can test them systematically and make like a grid along with a correlation of th…

The adapters giving problems are all directly PCMCIA/Cardbus to SD.  I successfully set up my 16gb card - the one that had the weird OS 8.5 Disk Tools System Folder on it - with th…

Lets go back to the very beginning... You got... A CF in a PCMCIA adapter that crashed a 3400 and gives problems on a 5300? It gave  a Sad Mac on the 3400 and then bars on boot wh…

The floppy drive has been very well tested and works perfectly.  The disk also works perfectly. I was going to say the SCSI enclosure didn't work but it appears to be booting to O…

Elfen said: I think you can turn the unit on as a SCSI Drive and connect it to another Mac through the SCSI Port and inspect the drive like modern Macs can connect by FireWir…

bigmessowires said: A commenter on my blog also pointed out this homebrew adapter based on an Altera DE0-Nano. It's got a very nicely detailed write-up of how it works. https…

Yes, I'd like one as well for my IIgs. Maybe if I got one, I'd actually use it! c

raoulduke said: It doesn't seem to be able to boot from floppy.  It starts to boot normally and then on the smiling mac it spits out the floppy and goes back to the flashing …

I really like that adapter.  If you decide to make any, BMOW, let me know.  I'd love to buy one or two.  Replacing an aging CRT with an LCD for my Apple IIs would be pretty handy. …

Gorgonops said: For authenticity (I guess) those scalers render the border area in their output, and what that ends up translating to is on, say, a 1280 pixel wide LCD displa…

I mentioned earlier in the thread that I've been using one of those "CGA to VGA" boards on my IIgs setup. (And I'm forced to be pedantic here: those boards *are not actually "CGA";…

Perhpaps its scaler is better, but my monitor won't accept 15 kHz RGB, so it can only use composite video. I'm guessing 15 kHz RGB converted to VGA with one of these CGA adapters w…

Yes, that unit will work, but the quality is likely "eh", "meh", or non-existent. The GBS-8220 board that likely came out of the same factory in China is commonly found for $30 or …

On the topic of IIgs RGB video output - does anyone know if it's the same as CGA video, found on old PC graphics cards? CGA is also described as a 15 kHz video signal with analog R…

It actually gets worse.  I replaced the HD and hooked it up to a SCSI enclosure that has electrical outlets on the back of it (which I say to distinguish this first part where the …

Sorry for posting so late. The SD needs a minimum of 3.3V, as per Raspberry Pi's use of 3.3Vs instead of 5V. Question is, what kind of adapter do you have? At worst, I think, you…
