Is there an easy way to run KS3.0 on A1000?

I only ask because getting a rom board for an A1000 is an exercise in futility these days and I can spare the RAM to load up the 16bit version from the 500/2000 after KS1.3 loads into the WOM.

I'm guessing C= never gave a damn about A1000 users in the 90s when KS3 was out right? So no disk based official solution for the 16bit machine. Shame.

(before anyone asks I already own a KS3 machine which I purchased for full price on launch day for the princely sum of 400 bucks, so it's not piracy if I don't use both machines at the same time )

But how does KS3 fit in the A500/2000 then if it is replacing a smaller sized ROM? How does it get mapped into the memory map? I assumed size was the reason you needed an A500/2000 specific ROM image.

Zkick is for KS2 only I believe, Skick refuses to allow KS3 to be loaded if you boot with 1.3 and crashes if you boot it with KS2 in RAM on my A1000.

I know the KS3 won't fit into the WOM, but Skick happily loads either 1.3 or 3.0/3.1 on my KS2.1 2MB A600 BUT on the A1000 it happily proclaims KS1.3 is resident and you can't load KS3 if you run the program from WB. VERY ANNOYING lol

I have 2.75mb on my A1000, nice little machine although the internal drive is fussy which is why half the time I need to boot from DF1 as that drive is less fussy and if I have to boot KS2 half the time I wondered if anyone else had managed KS3 or 3.1 on an A1000 into Fastram.

Guess I will just have to carry on X-copying using DF0: as the destination drive to get my stuff working...ho hum.

A500/2000 address decoding provided space for 512 KB ROMs from the start. A 1.2/1.3 ROM just appears twice in that space, lacking the A18 pin.

See. I knew it was best to wait for someone here with knowledge to explain it rather than relying on random google results claiming it's because they are 16bit or something

I really don't understand why skick doesn't give the option to go to KS 3 or 2 if you boot up the A1000 in KS 1.3. I might try it with KS 1.2 boot and see if it decides to work tomorrow. The RAM works fine and runs all my 1mb games properly so I don't think there is an issue with the RAM. Also SYSINFO reports the machine is 1.29 the speed of a stock A500 (maybe I forgot the 68010 in there from 1991!)

I'll have a bash at creating a real disk from a download of twinkick and see how that goes.....something useful to do with the spare ST Format coverdisks haha.  Thanks to everyone for their suggestions, appreciated.

did you read the instructions?
the tkg.exe is very unflexible
rom-filenames must be UPPERCASE


( twinkick3.9 - os1.3 & os3.9 -68000version- )

Why does a1k.org have an A500 in its banner image

I'd never do anything so drastic to my A1000 as getting the soldering iron out myself, I like its 100% percent originality as it came out of the box in 1986 Also don't know if I trust google translate enough to build an electronics project from the original German instructions
