Amiga Workbench 3.1 Rom

I have recently attempted to fit a Workbench 3.1 kickstart ROM to anA500 with a revision 5 motherboard (not forgeting to connect pin 1 to pin 31).The result of this was a 'dead' amiga, so the original 1.3 chip was replaced& all was well again.A call to the supplier of the chip & software said there is a modificationthat is required to revision 5 motherboards.Does anyone know the details of this modification or how I can find out thenearest Amiga service centre ?Also, what is considered the best way of jumpering pin 1 to 31 ?Ta in advanceRichard Harnwell

That is the gist of it, perhaps someone else has a more precise description ofwhat to do.Regards,Byron... __ __ __ /// "Byron Montgomerie" Internet: by...@saturn.cs.mun.ca __ /// \\\/// "Does anybody here remember Vera Lynn? \\\/// \XX/ Remember how she said that we would meet again, \XX/ Amiga some sunny day..." -- Pink Floyd -- Amiga

The floppy disk set can be used alone (to boot and use the system), or to create a new Hard Disk or Compact Flash installation. Enhancements include the installation of workbench.library, Installer v43.3 (on 68000 or 68010 CPUs) or v44.10 (on 68020+ CPUs), and FastFileSystem v45.9.

The 3.X ROMs have a size of 512 KB, and are therefore compatible with all Amiga models except for the Amiga 1000. In order to make room for the enhancements, the 3.X ROMs employ the same technique used by Commodore for the 4000T ROMs, i.e. ROM space was freed by moving workbench.library out of the ROM. This means that a "Libs/workbench.library" file must be present on the boot disk, as detailed below.

Required "workbench.library". Because workbench.library is not part of 3.X ROMs, a "Libs/workbench.library" file, as included in the Classic Support 'Workbench 3.1 disk set by Cloanto' and the 'Workbench 3.1 Compact Flash by Cloanto', must be present on the boot disk. This requirement is in common with later 3.1 ROMs by Commodore and ESCOM, as used with the Amiga 4000T model.

Online Support: Each 3.X ROM set comes with a license key that can be used to download the ROM or the "workbench.library" file for installation or recovery purposes. To register for support, please refer to cloanto.com/genuine.

Hi all im a new amiga user and have a amiga 500 i understand i need a new kickstart rom to be able to load workbench 3.1im not sure what the rom does or what it contains as i thought you could just boot the os from a disk?if i find a new modern kick start rom where does this live on the board and will it break compatibility with older software and games?what are some useful workbench 1.3 software or do people not use this anymore?

hi thanks for your reply so whd are games that are to be installed on hds?i have seen these whd files and i cant get them to load.i have the gotek floppy emulatori would like to run a more modern version of amiga osi only have the 512k ram expansion board i didnt know you could buy bigger ones

You see you will have to invest a lot more to do so, that's why my advice is play these games on real floppy this is MUCH!!! cheaper.You need to transfer the ADF Images to the Amiga (best if it has 1MB Ram) and then write back to disk on the real amiga.You need some tools for this. Transfercable, Transfer-Software and Disk-Image-Software.

Thanks all i have the gotek but i really just want it to be able to play non aga games and run a nice version of workbench so i can use office software ect.i have the 512k ram expansion that came with the computer is this slow ram? and if so how do i upgrade the ram as the only port i know is the trapdoor expansion.it would be nice to play aga games ect. bit as others have mentioned i will most likely need a 1200

You'll have to decide what kickstart/workbench you want to run. Version 3.1 is the last original Commodore Amiga kickstart. You can run Amiga OS 3.1, 3.5, and 3.9 with it. 3.1 is very common to run. There's also Hyperion versions of 3.1.4 and 3.2. I run 3.1.4 myself -- 3.2 just came out and I've seen some people have issues with it depending on their mods/upgrades. For the Hyperion OS's mentioned, you run the corresponding kickstart ROM with them.

If you just want to run a nice version of workbench and boot games via the Gotek (which would be the cheapest option), you can use a IDE68K for installing the OS to a CF card. A whole variety of programs/software can also be installed to the CF card and run from it.

hi thanks all im very much set on keeping this pc original as possible. i just want to run workbench 3.1 so what kickstart rom do i need? what is the benefit of amiga os over the original workbench?also in regards to the Blizzard 1230 where does this expansion plug into? can i run workbench 3.1 or amiga os without IDE68K also where does IDE68K plug into?sorry im a noob at this im more of a dos/commodore 64 person

For workbench 3.1, you use the kickstart 3.1 ROM. You can buy one, or burn your own with a chip programmer. It replaces the currently installed one. There are also kickstart switchers that you can use a toggle switch to swap ROM versions before booting. But if you go with an accelerator board, some of them have built-in kickstart switching too.

Ok I've finally got the TF534 working!.Turns out there were two issues preventing it's operation.1. The jumper on the Garry chip that enables the additional 512k of chipram was on the wrong setting. This is the jumper closest to disk drive (right side of the Garry chip). Since it was incorrectly set to the '512' setting and i'd made the solder mod to JP2 it was somehow preventing the TF534 from operating. It's worth noting that in this configuration with the Garry jumper set to '512' and the 68000 chip installed the A500 operated normally.2. As you hinted at in your last message I installed an IDE -> CF card adapter on the TF534 and once this and the Garry chip jumper was set correctly it booted to kickstart!. I then plugged in my modded GVP A500 HD+ 8MB (it has a SCSI -> Micro SD adapter conversion) and bingo all working now.Picture links below: -heroes.eu/files/amiga/a500-03.jpg -heroes.eu/files/amiga/a500-01.jpg -heroes.eu/files/amiga/a500-02.jpgMany thanks for your help and advise Thandor This reply has been editted 2 times.
