    Description

    Apple //e Enhancement Kit without the CPU -- For Apple ][e 2e or hardware compatible clones (Pravetz 8A or 8E, etc.) upgrade (UK-English, USA-American, FR-French and DE-German version available, please advise prior posting which one you'd like to receive, the default one is the US version wth 24-pin Video ROM which is not compatible with the international Apple //e motherboards that require 28-pin Video ROM!) The 65C02 or 65SC02 DIP40 CPU is NOT INLCUDED, there are numerous sources on ebay and elsewhere where you still can obtain one. Just use the SLOTSCAN program (I can provide a link to a DSK image with it if you don't have it to test if you have purchased the 'C"" version of 65C02 or 65SC02 because practically all Chinese sources provide relabeled remarked refurbished (with straightened pins / soldered pins) CPUs and you never know what's inside until you test the C CPU version instruction set with SLOTSCAN. The Apple2 users are fine that Apple 2e's require only the 1 MHz version of the CPUs so it irrelevant wheter the frequency marking of the CPU you purchase elsewhere is forged or not.
    Here is my list of some Chinese ebay sellers from which you may receive not what is indeed advertised by them.  Those sellers are:
    gowin_electronic
    polia2008
    chipsgate, etc...
    I am giving up and leaving you the pleasure for hunting for 65C02 CPUs...
    Apple upgrade kit (The Chips are newly programmed EPROMs and tested chips for longer life)
    Very easy upgrade, just requires replacement of 4 ICs.
    Adds extra commands, compatibility, ability to type BASIC in lower case, and alters the boot message from ""Apple ]["" to ""Apple //e""
    Contains :
    CD Monitor ROM (27(C)64) or equivalent;
    EF Monitor ROM (27(C)64) or equivalent;
    Character Generator ROM  (US, UK, FRENCH or GERMAN version of Apple ][e motherboards, please inform us of which one you need) (2732 or 27(C)64 or equivalent depending on version)
    NOTE:MOST OF THE FEATERS LISTED BELOW CAN BE USED WITH YOUR CURRENT 6502 CPU UNTIL YOU OBTAIN A 65C02.
    From an Apple website :
    The Apple IIe Enhancement improves the performance of the Apple IIe by replacing four chips on the main circuit board.
    The Enhancement has four major benefits:
    1. Apple IIc compatibility:
    Users can take advantage of software developed for the Apple IIc.
    2. Product line consistency:
    Apple II software can be used on both the Apple IIe and IIc.
    3. The MouseText character set makes it easy for developers to create
    software that uses pull-down menus, windows, and icons.
    4. Easier programming for users:
    a. Accepts BASIC commands in both upper- and lowercase
    b. Additional instructions in the 65C02
    c. Mini-assembler for machine language programs.
    Feel free to ask questions. The chips you will receive are 100% tested and are vintage refurbished and freshly programmed and verified ICs and could be different from the pictured (their brand and batch code and the stickers on top will be somewhat different than pictured).
    Shipped from EU. Don't hesitate to ask questions -- I have a lot of vintage PC items from the same era. Thank you for reviewing this listing.
