256.0. "ROM replacement for Kickstart" by NEPTUN::BERKSON () Mon Jan 19 1987 10:05

    In usenet I read about a ROM set which takes the place of the Kickstart
    disk and adds 256K of RAM. I don't remember if it also takes the
    place of the Workbench disk. Does anyone else have this and do you
    think it's a good thing? Does it replace the Workbench disk too?
    Also if you could post the address of the place that sells it, I'd
    appreciate it. Thanks.

256.1Coronary CareAUTHOR::MACDONALDMon Jan 19 1987 10:136
    It is on the shelf at Memory Location. Requires a soldering iron
    and the tearing down of the Amiga. The conversion is not for the
    weak of heart! It really doesn't ADD 256K of RAM, but merely FREES
    UP that amount by using an Eprom coded with Kickstart V1.2.

256.2Kickstart in ROMELWOOD::PETERSMon Jan 19 1987 10:2413
    
    	The Memory Location has the ROM Kickstart for $130. It replaces
    Kickstart not Workbench. It also gives you 256K more memory ( the
    old Kickstart RAM ).
    	The kit contains more than just ROMs. It contains 3 ROMs, a
    PAL, sockets and Jumpers. You must install sockets for the rom and
    the PAL. Remove the old ROMs ( from sockets ) and install some push
    on jumpers.
    	When done, you can select Disk or ROMs for kickstart by the
    jumper setting. The ROMs are Kickstart V1.2 .

256.3No option to "fall back" to V1.1 disk.HYDRA::MOOREW. Bruce Moore =]8^)Mon Jan 19 1987 19:477
    Ah, but there is a small catch...
    
    I was in Memory Location on Saturday.  One of their machines is
    running with the Kickstart in ROM.  Somebody wanted to try out a
    program that was not compatible with V1.2 and had to move to another
    machine to run it.  Apparently there is no way to load Kickstart
    from disk once the ROM version is installed.
256.4The future?HOUSE::FRACTALMon Jan 19 1987 22:455
    
    	Does the company that sells this kit support future versions
    for a small fee? Or will you have to buy the kit all over again.
    What was the program that didn't work. was it Ea distributed?
    
256.5Sure You CanAUTHOR::MACDONALDTue Jan 20 1987 08:039
    Actually ... there is a way to boot Kickstart from disk after the
    new chips are installed. There is a dip-switch that can be flicked.
    Unfortunately, the location of it is such that you'd need to open
    the case. Although, no reason why a microswitch couldn't be brought
    out to the backside of the case. That's what I did with my Epson
    to switch from serial to parallel ports - a microswitch on the backside
    and a tiny relay inside.

    Deluxe Video will not work properly with 1.2.  I called them about
    it yesterday, and they said that they are still working on a fix.
    When you try to run it with 1.2, you get requesters filled with
    garbage, or nothing at all.  It also has problems with expanded
    memory.
