A1000 setup with 1MB memory?

[lifeschool]

Hi

I am using WinUAE 3.3.0 with an A1000 NTSC setup, KS 1, WB 1.0

I seem to be able to configure 512k of ram but whatever I try to do above this and it wont work, I tried Chip, slow, motherboard, Z2, all options.

When I load WB, I only have round 256kb free, so there isnt enough memory to run even the boingball demo.

What am I doing wrong?

Kickstart 1.0 doesn't support any RAM other than chip RAM directly.

You'd need to add non-AutoConfig RAM, then run a 1.0-compatible memory-adding program in your startup-sequence.

Sorry for being such a noob, but I dont have a clue how to do this.

I found AutoAddRam by Jonathan Potter which appears to work with KS1.0

I added 2MB z2 ram in RAM, and made sure the 'auto config' was not selected.

I ran AutoAddRam with the memory address locations it stated in the documentation for adding 2MB to the memory list file :

400000 5ffffe

but it just crashed with a software failure.

Can you tell me the locations I should be using for 2MB?, or 4MB would be great.

Wait for next beta. It has easier way to configure non-autoconfig RAM.

(address space most likely is 0x200000-0x3fffff when using 3.3.0 z2 RAM without autoconfig)

AutoAddRam requires at least Kickstart 1.2. The AddMemList function which it uses was first implemented with Kickstart 1.2. Plus it uses OpenLibrary (Exec -$228) which wasn't implemented in 1.0.

I do remember seeing a 1.0 (or 1.1?)-compatible memory-adding program but don't remember where.

You could try experimenting with a Tecmar T-card config, since the Tecmar software can add its on-board memory.

Perhaps a future version of WinUAE could have an option to add non-AutoConfig RAM automatically under Kickstart 1.0/1.1 (if a shared drive is configured the memory could be added before handling that).

I guess I can add some A1000 non-autoconfig boards to 3.4 memory board select menu.

Nothing will ever be automatically enabled.

Sure, I meant there could be a checkbox/option for the user to choose to have it added automatically at boot time.

Thank for your help with this. Yes I guess I will wait patiently for the next beta.

I tried the memory addresses you gave but it crashed.

I added the T-Card and it did nothing.

I added more ram slow and Z2 after this but still no change, and sometimes the machine failed to boot, giving a black pointer in the lower corner of a white screen.

I tried ECS Agnus for 1.0MB chip ram, but nothing.

Yes I just wondered if it was possible to play a game on an old A1000. Whatever I select, it just gives 256kb. I thought the A1000 released with 512kb?

This is on Old Computers.com
"A1000: 256kb, upgradable to 512k internally. Extensible to 8.5 MB with extension card (512 KB CHIP RAM + 8 MB FAST RAM) and to 10 MB"

I realise WHDLoad probably wont even run on KS1.0 anyway, but maybe it will work with KS1.3 and WB1.0? Thats my only alternative for now.

[mark_k]

Is there any reason you specifically need to use Kickstart 1.0? If you use 1.2 or later you can add up to 8MB of Zorro II fast RAM which will be used automatically. Plus hardly any software works on Kickstart 1.0.

[idrougge]

Even the very oldest Amiga games tend to depend on Kickstart 1.1.

[lifeschool]

As I said in the OP, with 256k there isnt enough to do much in memory. I wanted to run the Boing Ball and a few demos together to demonstrate multitasking.

I wanted to show the Power of the A1000 computer for my new documentary. But with 256K its like having 4 Commodore C64 memory banks linked together, to run an Amiga!

Yes you are right, with 1.1 came games and 1.2 came the applications, and by 1.3 they had got it right. But this I dont wish to cheat unless I must. Its ok, this isnt important, it was only an experiment.

There is an AddMem program on the Amiga Macro Assembler disk which should work with Kickstart 1.0. I've attached it here.

Original A1000 was with 256Kb on board, in front is slot with other 256Kb, and it was usually in all models that I have seen.
I used to have 4Mb extension with KS1.2, then SupraTurbo with 28MHz 68000. That was funny one to have backwards on A1000...

[mark_k]

The 256KB front add-on board increases the machine's chip RAM from 256KB to 512KB. In WinUAE, just adjust the chip RAM slider to 512KB.

You should also be able to add "slow" RAM up to 1.5MB then use AddMem to add it. On a real A1000 the slow RAM isn't necessarily slow, so you could check the "C00000 is Fast RAM" option in advanced chipset settings to replicate that.

I tried this from the start but no matter where I move the slider, it only pops up as 256k. I have Compatible Setting selected in Chipset.

I added 1.5MB Slow Ram and ran ADDMEM you linked. It seemed to run but again I dont know the hex address for the memory location. I tried 200000 3fffff but it just froze.

[mark_k]

Slow memory starts at $C00000.

[lifeschool]

Ah right. Thanks a lot.

I selected 1.5mb slow ram and used addmem with the following syntax:

Addmem C00000 D00000

It added 1MB to the system and thats wonderful, I now have 1.2 meg instead of 256k to play with.

So now this is running smoothly, is there anything out there which I can run on WB1.0? I am guessing that not much was written after its release in Sept 1985, as 1.1 came out in Nov 1985, and it looks like 1.0 was just a test demo and nothing 'modern' will work with it. Stuff like sysinfo etc I guess would be no chance. Again, thats ok. Even the oldest boing ball I can find is in PAL and I use American NTSC, so even that runs with some issues.

[mark_k]

You could do AddMem C00000 D80000 to add all 1.5MB.

I think all the Boing demos were intended for NTSC machines. But there were several versions and only the earliest works on Kickstart 1.0. See the thread Original boing ball demo. If you read through that, stevsurv uploaded a 1.0-compatible version (22-Aug-85) back in April.

(Also, the 1.0-compatible Boing demo probably won't work with fast RAM...)

[lifeschool]

Thanks. I now have 1.8mb to work with.

I read that old boing ball thread before I made this one. The program the guy says works on 1.0 doesnt work on my system. The one I have from Aug 1985 draws slowly with crashed colours and then the software fails.

The August one came out before WB 1.0 release in september, so I dont know if it is meant to work. Oh well. Thanks anyway.

[mark_k]

I'm not sure what the problem with your not being able to set chip RAM to 512KB is. But the 1.0-compatible Boing demo probably won't work with any non-chip RAM. Meaning, if you try to run it after using AddMem, it won't work.

Could you run WinUAE with the -log argument and try moving the chip RAM slider? Also, you could attach the config file you're using so I can take a look at it.
