The Apple IIe Platinum is the last version of the Apple IIe, introduced in January 1987 and made until Apple dropped the IIe from its price lists in November 1993.[1] It has a platinum-coloured case, an extended keyboard with a numeric keypad, a smaller chip count and a 64 KB extended 80-column card fitted at the factory. Apple's service notes describe the logic board as having no major circuit changes and being fully compatible with all previous IIe logic boards.[2]
Changes from the enhanced IIe
[edit | edit source]- 64 KB of RAM in two chips instead of eight, and one ROM chip instead of two[1]
- A 64 KB extended 80-column card, smaller than earlier versions, in every unit, so 128 KB and double high-resolution graphics are standard[1]
- A keyboard like the Apple IIGS keyboard, with RESET above ESC and "1" as on the Apple IIc and the power light above "/" on the numeric keypad. The internal numeric keypad connector remains on the board.[1]
- The CLEAR key on the keypad generates the same character as ESC; a hardware modification makes it generate Ctrl-X as on the IIGS.[1]
- No ROM changes: the Platinum runs the enhanced IIe firmware.[1]
Apple's parts list gives 607-5015 for the platinum case and lid and 661-0357 for the Apple IIe Extended Keyboard, platinum.[2]
The factory shift-key modification
[edit | edit source]The Platinum has the single-wire shift-key modification made at the factory, so that programs can tell whether SHIFT is pressed.[1] Apple's service manual gives the reason as letting mouse-based applications detect a shifted click, and warns that on an X6-jumpered board, pressing SHIFT while game switch 2 is closed shorts +5 V to ground and shuts the power supply down.[2] The 1982 Apple IIe Reference Manual gives the same warning for owners who made the modification by hand, and adds that anything in memory is lost.[3]
To separate the two functions, Apple's procedure is to find the X6 jumper pads to the left of the keyboard connector, cut between them with a craft knife, and check with an ohmmeter that they no longer connect.[2]
Variants
[edit | edit source]A community comparison table sets out the variants and their model numbers.[4]
| Model | Market | Case and keyboard | Supply |
|---|---|---|---|
| A2S2064 "Apple //e 128K" | USA, from about October 1986 | Original IIe case and keyboard, no numeric keypad; Platinum board with the miniature extended 80-column card | 120 V |
| A2S2128 | USA, January 1987 | Platinum case; new keyboard with numeric keypad | 120 V |
| A2S2128C | Canada | As A2S2128; dual character set, French-Canadian and US English, toggle switch under the keyboard | 120 V |
| A2S2128X | Australia and New Zealand | As A2S2128; International NTSC board; dual character set, UK and US English, with toggle switch | 220/240 V |
| A2S2080 with a country suffix | Europe | Platinum colour in the original IIe case, no numeric keypad; assembled in Ireland | 220/240 V |
Motherboard part numbers recorded include 607-0187-C, -D and -E (USA), C607-0187-E (Canada), and B607-0288-C/-D/-E, F607-0288-C, D607-0288-D and S607-0288-D on International NTSC boards.[4] A2S2064 is the American "Apple //e 128K"; the European model in the old case is A2S2080 with a country suffix.[4]
Power supply
[edit | edit source]The specification is the same as the Apple IIe's: +5 V ±3%, +11.8 V ±6%, −5.2 V ±10%, −12 V ±10%, 107-132 V AC in, 60 W continuous and 80 W intermittent, maximum case temperature 55 °C.[3] Apple's service replacement for the IIe family is 661-0455. A later replacement supply is 1.5 inches longer than the original and fits any IIe; it resembles the Apple IIGS supply, but the two are not interchangeable.[2][5] 220/240 V machines take a different supply.[4]
Mains potential is present on the primary side of the supply. See Apple II General Maintenance for the hazards and the procedure, and Capacitor Failure Symptoms.
Things that are not faults
[edit | edit source]- A platinum machine in the original IIe case with no numeric keypad: A2S2064 in the USA, A2S2080 in Europe.[4]
- The CLEAR key producing ESC.[1]
- A shutdown when SHIFT is pressed with game switch 2 closed. This is the factory shift-key modification.[2][1]
