Yeah OK. I always thought it was too bad they discontinued the DB-19 port on the Color Classic, for this exact reason, since it was the last of the compacts anyway. It's the only one that can't use an external floppy drive. I presume you have the Apple 3.5" external (800K) on the SE (two...

I guess the point is, if there is no other damage to the case, then it can easily be de-yellowed to near new condition. Then it can be sold. I've got nothing against borrowing parts from one to the other, but then it comes to dismantling irreplaceable parts on a 128K and 512K, like fly-backs...

H3NRY, when you say three different versions, Did you mean three sets of Hi & Lo ROMs? I am only aware of two ROM sets. The original (340-0220/21-A), and the 400K floppy stepper-motor revision (342-0220/21- B) . Where does the third set fit in?

Gubbish, congrats! Before you do any more work with that unit powered on, make sure you check the voltage and adjust for optimal conditions. Having cleaned it up, it will give you a false sense of security, and could easily tax the aged and poorly stored components to a literal melt-down. This...

Those DRAM chips are the large silkscreened Apple logo. My experience has been without exception that usually one or more of those chips will have failed by now. This is not the case for non-Apple branded DRAMs. Nothing conclusive, but I blame bit rot. If the poor storage conditions are at...

Pina recommends 150ns DRAMs. However, nothing lower. 200ns is the minimum standard required by Apple.

The reason Pina says on page 65 that it is a 512K board, is because there is typically no other reason to remove the ROMs from a 128K board.* That is not always indicative of the problem. As techknight points out, there could be several other reasons for this problem, which had not yet come to...

What exactly does this mean? DRAMs are DRAMs. The early DRAMs were Hitachi 4864, and the later large Apple branded chips were 4264 as well. Apple used DRAM from many sources. Larry Pina even indicates 4164 works in the 128K. The presence of an Apple silkscreen only indicates Apple got a deal on...

Lot's of great pictures. I like the modern approach to documenting the un-boxing we see for all new Apple products today ... did anybody ever think of doing this in 1984? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=280642431829

Yes you definitely have an early copy of the System there. So now we have the first known copy of the System to predate .85 The "Aternate Disk" is what the "Unknown Disk" was called originally, and appears throughout the first edition manual which had to be written and sent to press well before...

First make backup copies, and the use ResEdit on the copies to check the resources of the System and applications. In particular size of various resources will be a good indicator as to what has changed from the release versions. Mini vMac is an especially helpful tool for this kind of...

Scott, I believe when the link comes up again, you will find that those are both 240V EDs. Even if they were 512Kes, they would necessarily have to be imports, as it wouldn't make sense for Apple to sell 120V products in a country that supplies double the voltage over standard outlets. And...

Ah, the smoking gun! Thanks for posting that picture again. Definitely Platinum. Clearly the evidence is overwhelming. But that one sticking point remains. Is the box indeed original to that Mac? Seems highly likely ... I'm just bothered by the paucity of evidence of more Platinum 512Kes in all...

SEthirty - start another thread, doesn't belong here.

This doesn't really qualify as a rare model ... It's a rare SE/30 in that there likely only a few thousand manufactured prior to its release in January 1989. But definitely not a rare variant. This is similar to the 1983 128K Macs, rare for the model, but otherwise mass produced in huge numbers...

The model numbers. How it was marketed. 512ke M0001E ED M0001ED 512K/800 M0001D Show me a 512Ke with a model number of M0001E in Platinum, and we'll know for sure. Until then we only have one known suspect example from an eBay auction Eric sadly didn't bid on! LOL

My argument is not whether a 1987 Mac 512Ke would be Platinum or not. It's whether the 512Ke was sold with that badging after it became Platinum, or not. Due to Apple's tight supply chains, the fact that the ED used the Mac Plus bezel would suggest that it switched when the Mac Plus did, that...

Why is this posted under "Compact Macs"?

This makes a lot of sense frankly. There's no use bemoaning Apple's abandonment over what are now 25 year old GUI features. Apple is a company and as such is interested in growing and drawing new, younger users into using it's products. To that end, I think it makes an enormous amount of sense...
