Well, I've recapped as much as I can. The post which had all the values and sizes was inaccurate.

All the low voltage Nichicon caps were really leaky. Thankfully all but one of them had been documented correctly. Unfortunately one was said to be 47uF 16V but in fact should be 100uF 35V and I didn't have one of those in stock so I had to replace the original even though it was leaking.

All the caps on the high voltage side were fine, though I couldn't replace the two small RIFA-alike film capacitors as, again, the documentation was wrong and gave the wrong dimensions, so the caps I bought were way too large.

Anyway, it's all back together and the voltages look fine but the machine still has the low voltages on the RGB output when first powered on, which slowly rises to the correct value over a couple of minutes.

The boxed, new (to me) Apple 8.24 NuBus display card has arrived, so I can see this evening if the NuBus slots actually work. (Assuming that this isn't another DoA card.)

It works!

So, the NuBus is operational.

The system really flies with the new graphics card, even under 7.5.5. The card isn't even accelerated.

However, it is allowing the 25MHz 68030 to run at full speed without the video sub-system getting in the way.

Nubus run at 10Mhz I think ...

It does.

Hmm... it feels wrong bidding for unpopular (but probably working) Apple machines on eBay because I just want the floppy drive, but it seems to be the cheapest way to get one.

Outbid in the last minute on the Performa 630, so no new floppy drive.

I've got a ZuluSCSI unit on order but it's from AmigaKIT (*spit*) as they seem to have the UK manufacture/distribution rights. It's therefore probably going to be weeks until the order is even acknowledged but the money will come out of my account straight away.

Bought a rather yellowed but otherwise functional (except for hard drive) LCII for a bit more than I was expecting, just for the floppy drive, but still cheaper than a bare drive!

I'll remove the drives, recap and retrobright the machine and sell it on I think, to recoup some money. LCIIs are slow and restricted relative to the IIci.

The lc2 is a good machine to rescue it the caps and battery has not killed it. Good place to get the drive
