2655.0. "Amiga 500 to 1 MEG upgrade" by SYSTEM::HELLIAR () Mon Jun 19 1989 08:01

    Hi
    
    Having got my A500 a while ago I now find I need more memory
    (i.e. I want to upgrade to 1 Meg).
    
    Has anyone got any suggestions on the best (cheapest?) way to do this.
    Please note I'm not a hardy so whatever the solution is must be for
    the non-technical minded.
    
    				Thanks in advance

2655.1Standard option - A501BOMBE::MOOREBaN CaSe_sEnSiTiVe iDeNtIfIeRs!Tue Jun 20 1989 20:565
    Your best move would be installing the A501 (or one of its "clones").
    I think these are selling in the $125-$150 range.  Installation is a
    breeze, just pry open the door in the bottom of your A500 and plug in
    the RAM unit.  It includes a nice battery backed-up clock too, so you
    system will always know the correct date and time.

    There are some previous notes (1273, 2594) which sound as though
    installation may be not that simple. Is this still the case.
    
    Re .1 : Do you know of any names for the clones (available in the UK)?

2655.3Don't worry about itMEIS::ZIMMERMANFresh from the sewer!Thu Jun 29 1989 21:345
    My Microbotics .5 meg expansion was very easy to install.  I just 
    popped open the hatch on the bottom of the A500 and plugged it in.

2655.4 no problem here eitherOZZAIB::ROSCETTISome things u never get used toFri Jun 30 1989 11:223
    
     The A501 .5 was strictly plug and go for me.
    
2655.5Lets move the goal postsSYSTEM::HELLIARGraham @REO-F6-3, DTN 830-3173Mon Jul 03 1989 04:1511
    Thanks for all the info and I've looked around and the A501 will set me
    back at least 100 pounds sterling.
    
    Next question :
    
    Is this the right way to go. I've already found 0.5 Meg isn't enough
    will I have the same problem when I get to 1 meg. i.e I'm looking at
    constantly adding to the A500 as time progresses rather than buying new
    machines. IS there a better solution (obviously it will cost more) to
    give me the extra 0.5 meg I need but also allow for future
    requirements?

    If you can afford it, there are numerous SCSI/hard drive/RAM boxes that
    connect to your A500 either by slapping onto the side or via a cable. 
    These boxes usually have a board that is socketed for 2 MB of expansion
    ram.  Prices average about $700 around here for the GVP Impact A500-20
    or the Xetec Fasttrak Jr.  Both products include their own power
    supply, but exclude the extra ram chips.  The beauty of these little
    boxes is that you kill three birds with one stone; hard drive, extra
    memory, and included power supply.
    
    Both the GVP and Xetec were highly rated by AmigaWorld.  Commodore
    must be shipping their own version (A590) by now, but I haven't seen it
    at my dealer.

Yes unfortunately, this is the way to go. This 2nd �Mb is the memory (A501)
used by the ECS (fatter agnes et al) to give you 1Mb chip memory. (It
brings the A500 up to the same memory configuration as a stock A2000).
So you would probably want to get it in the future even if you didn't
get it now.

Some memory boards for your A500 do allow themselves to be configured in
512, 1Mb or 2Mb increments, check out the MiniMegs memory expansion
board from M.A.S.T. (Ads in most UK mags) which sells for something like
�179 populated to 512K.
(But NOTE that this is not the same 512K as an A501 would give you !
i.e. installation of a fatter agnes chip wouldn't give you 1Mb chip -
you still need an A501 or equivalent for that).

Hmmm re-reading this, it seems as clear as mud, sorry! If it's still not
clear I'll try again later....

2655.8Here's mud in your eyeSYSTEM::HELLIARGraham @REO-F6-3, DTN 830-3173Tue Jul 04 1989 05:4814
    RE .7	YOur right about the mud.
    
    I read a review of the A590 and it seemed great for a price of
    400 Pounds sterling. Unfortunately the extra memory chips have to be
    bought seperately and have to be CMOS ( 8 chips at 22 pounds a throw!)
    for my required upgrade to 1 Meg.
    
    The acticle as memtioned an A501 but I't wasn't clear if this comes
    inside the A590 .
    
    To summarise the question :
    
    SHould I go ahead and buy the A501 irrespective of my future upgrade
    requirements?
2655.9Go for it!FRAMBO::BALZERChristian Balzer DTN:785-1029Tue Jul 04 1989 07:3312
    
    Re: .8
    
    Yup, you should.
    The A501 will give you:
    a) A battery backed clock, which is very nice to have, and
    b) the RAM you will not want to miss when you get the obese Agnus
    (1MB of ChipMem).
    
    Less muddy?

2655.10Decision timeSYSTEM::HELLIARGraham @REO-F6-3, DTN 830-3173Tue Jul 04 1989 08:548
    OK I'll have to buy it.
    
    Funds don't permit the purchase of it at the moment so if anyone hears
    of a second-hand one going for a song then please let me know.
    
    					Thanks for all the info

2655.11Agnus needs to put on weightSIOG::WOODSThu May 30 1991 07:045
    
    Looking to upgrade Agnus to 1 meg. I`m looking for information about
    upgrading ie. how to fit it, could I put in any 1 Meg chip ! and which
    is the best name (and cheapest).
