4078.0. "Help on A2000" by COMICS::HOGGAN (No, I am not kidding !!!) Tue Sep 04 1990 08:27

    Hi,
    
    I upgrading from an Atari STe and have a chance to buy an Amiga A2000.
    It is a revision 4.0 board and was wondering if this will cause me any
    problems in the future? Can anyone help? It has Kickstart 1.3 fitted.
    
    All help will be appreciated.
    
    Thanks, Dave.

    Hmmm, I seem to recall a note that went into exacting details about
    each revision of the A2000 motherboard, straight from the designer
    himself.
    
    I think the important thing is that you get ANY B2000 motherboard, as
    opposed to an early, German-designed A2000 motherboard.  (The A and B
    designations are arbitrary).  The German model (of which few, if any,
    were sold in the States) does not have the video slot and cannot be
    upgraded beyond 512k of video memory.
    
    I have an early 2000 model that came with a 4.1 motherboard and
    has been running pretty much nonstop for over two years.

    Many, including myself, consider the Rev 4x boards better. There
    were only 2 known problems in pre Rev 4.5 boards -- The first having to
    do with some 3rd party controllers not functioning correctly, and
    the 2nd having to do with the 1st keystroke on the keyboard after
    a  system boot not taking effect (only on some models - when CBM
    changed keyboard manufacturer).
    
    Both problems are corrected by the CBM Rev 4.5 upgrade, which any
    authorized repair service can perform -- or you can do yourself
    since the entire procedure is posted in this file somewhere. I would
    not do this unless you actually encounter these problems with
    your configuration -- only certain systems had problems and only
    in specific hardware configurations. The only people I know that
    actually bothered with the upgrade are those that encountered the
    controller problem.
    
    There are a multitute of Rev 6.x problems reported however - mostly
    dealing with hardware than works fine in the Rev 4 series but doesn't
    work correctly or work in combinations (like SupraRAM 2000 w/ certain
    disk controllers) in pre Rev6.2.
    
    I'd buy it! You're not at any risk.

    I have an eary 4.x system,and have had no problems in several years. I
    looked into it and found many of the rev changes were layout only,and
    did not include any functional changes. To get to 6.x I'd have to add 
    a pullup resistor. I haven't bothered. Some of the problems with 6.x
    boards may well be related to the new etch layout,and increased speeds 
    seen on many of the faster cpu boards. All I know is that my 4.x(4.1)
    seems fine with the GVP 40meg,and CBM 2058 8meg board populated to
    4meg. I did have a problem when I added the last 2 meg,but that was 
    fixed by a pal update from GVP.

4078.5Memory boardsCOMICS::HOGGANNo, I am not kidding !!!Tue Oct 09 1990 15:338
    
    HI,
    
    Does anyone have any recommendations for memory boards for the A2000.
    I'm looking for an initial population of 2Mb.. UK prices an advantage.
    
    Cheers, Dave.
