Hi everyone - its been a long, long time since I've posted here, but my patience has paid off and last week I picked up some Apple IIe and IIc hardware! Thanks to Tezza for the lead - it was about 7 hours' drive from here, but at least on the same island!
All the equipment has been stored since the early 90's in a garage - the owner found them while cleaning up after the Christchurch earthquake. The drives were in a box with a 1993 mailer from The Warehouse so that helps quantify the length of disuse!
With the IIe's I decided that because the computers and power supply were easy to dismantle, and had been potentially not powered up for longer, I would completely dismantle and clean them up.
The IIe Enhanced is in bad shape. I found lots of crud etc on the component side of the system board, and lots of corrosion on the bottom of the case. The bottom of the system board was clean, as was the keyboard.
Opening the power supply I found what appeared to be the source - the whole thing was covered in foul smelling goo, and although there was no obvious bulding of the electros the mains filter cap (0.1uF X2) had blown up - something I kind of expected after the experience with my Sord M23's. I'm going to assume that the source of the corrosion in the case was the leakage of cap electrolyte out of the PSU onto the case - I could be wrong, it may be storage, but the rest of the gear is fine.
My gut feel is that the PSU may be a write-off - this goo is everywhere including on all the wound components (inductors and transformers). I will take it in to get looked at, but may have to use an external PC supply for a while.
The other system (straight IIe) looks fine - a bit of dust and a little grime, but the insides of the PSU are pristine (which was quite a relief!). Quite a different case, it has the older velcro-like fittings, screws in different places etc.
I have noted the part numbers from the power supply, sytem board and whole unit - I'd be interested in what info is around on these, and if this model of power supply is known for problems.
Apple IIe PAL (relatively good condition):
* System A2S2064P s/n 148845, assembled in Ireland
* Appears to be from mid-1983
* PSU A2M0030
* System board 820-0073-B, B-607-0264
Apple IIe Enhanced Int'l NTSC (marginal condition):
* System A2S2064X s/n E640045, assembled in Singapore
* Appears to be from mid-1986
* PSU 828-0510-A
* System board 820-0188-C, B-607-0288-C
I'll post some photos of the systems and card separately.
- Apple IIe PAL with printer card, Ramworks upgrade, CP/M card (I think - it has a Z80 CPU), Disk II controller
- Apple IIe Enhanced international NTSC with printer card, 80 column card, disk controller with D connector, and another unidentified card (possibly another printer controller?)
- Monitor ///
- Generic green composite monitor
- Disk II, clone floppy with Disk II connector, two Unidrives
- Apple IIc with Monitor IIc, stand, modulator, power supply, serial cable and "super cable" (whatever that is - still need to investigate)

The 80 column card (I'm assuming not extended) from the IIe Enhanced, the Ramworks card (two views) from the standard IIe and the two disk controllers - one with D connector for the Unidrives out of the enhanced and a Disk II controller from the IIe.
