hello,

my new (to me) Apple iie platinum computer has just arrived from the states , its in poor condition with a damaged keyboard and unkown working condition...

just what i like to hear.

Anyway a quick change of the PSU to a UK Apple ii and bingo shes working.

The keyboard is damaged and loosed , the plastics are scratches but it works and in full colour (its an ntsc)

im a very happy bunny - i need a new keyboard or at least some missing keys and a damn good clean. im using my spare 5.25 black disks but the the 2e should have the more modern white or even 3.5 disks.

Ive popped my spare 2e 80 column card in it and now it has 128k , the 110v PSU has been ejected for a spare 240v from a Apple II plus.


Okay - whats the difference to my 1978 Apple II?

Well a lot really, the first thing is the lower case keyboard, keypad and white colour. on the inside , the chip count is massively reduced as is the heat. My 1970s apple II generates a lot of heat but the new apple doesn't hardly.
Can i see a difference in use? Well yes apart from the obvious colour now, the machine seems a bit quicker and games play differently... what you say? Well Karateka plays the intro - on the old Apple it doesn't.

So is it the Apple II to buy ? i would say yes - don't buy the old 70's Apples unless you really want to. The 80s Apple iis are much better. i suppose i have to get a Apple IIGS now...

Things to do ..

needs a keyboard really and a top panel (maybe) some halfwit has scribbed writing on the plastic case with a knife or similar.
Duo disk drives at some point if they crop up cheap

According to Mitchel Spector:

In March 1985 Apple introduced the Enhanced //e. It was identical in every aspect to the original ][e, the only difference being four socketed chips had been changed on the motherboard: 6502, CD and EF ROMs, and the Video ROM. The 65C02 CPU added more instruction sets, the new ROM firmware fixed bugs and improved Applesoft BASIC, Monitor and 80 column routines, and finally the new Video ROM added "MouseText" characters first introduced in the //c. Essentially the Enhancement was to make the ][e more compatible with the Apple ][+ and IIc models. The original ][e (including the revision A board) could be easily user upgraded by simply swapping the 4 chips; Apple even sold an Enhancement kit upgrade.

In January 1987 Apple introduced the "Platinum //e". Changes were mostly cosmetic and superficial, with the biggest difference being that the case color was changed from beige to the then standard platinum/grey color. Also different was a numeric keypad was built-in and the main keyboard had the same layout as the Apple //gs and Macintosh SE. The motherboard was functionally identical to the Enhanced IIe, though the number of RAM chips making up 64K had been reduced (two chips instead of eight), the 16K ROM was merged into a single chip ("CF ROM"), and the shift-key mod was shorted to 'active' by default. Also, these IIe's shipped with 128K as standard (a drastically reduced version of the Extended 80 Columns Card was pre-installed in the auxiliary slot of each unit).
