I want more than 2mb Fast RAM on my A1000...how?

[Amiga_Nut]

Is there a technical reason why all A1000 zorro side expansion slot memory boards are 2mb max for the A1000? If I slot in an A500 8mb unit will it work or will the A1000 only see the first 2mb for some technical reason despite the Zorro 1 slot being identical?  If I use TWO 2mb ram boards and one has a pass through and connect them both together what happens? Fire? Explosion? Space-Time continuum folds in on itself and we instantaneously get transported back to 1960s?

OK cheers, I just stumbled upon an auction for another side car expansion (just waiting for the seller to confirm total RAM present on it) and that would give me 4 1/2 mb rather than 2.5mb I have now (only 2mb with KS2.0 softloaded)

I know 8mb is the theoretical limit due to the A500/2000 being limited to 8mb 16bit FAST RAM, wasn't sure why the A1000 never had a 2mb side expansion unit.

Actually.....I have a Comspec (?) 2mb expansion for my A1000 and I had to butcher the casing but the card works perfectly. Thing is....this beauty has 30pin 256kb SIMMs soldered onto the board (8 of them) now if I was to change these to 1mb 30pin SIMMs would I get 8mb....or a dead A1000?

Even labels them as SIMM1 .... SIMM2.... on the board. I have some 1mb SIMMs, can even test them on an ATARI ST (let the ATARI blowup before my A1000 init!!) but would it just work like some retro machines where you replace the DIL oldskool rams from 256kb to 1mb versions you think?

Today, I wouldn't even bother with such a scenario. Besides, 2.5mb RAM is plenty on an A1000 with 68000 and no hard drive.

Don't rub it in When I see an AddIDE and an accelerator suitable for 68k slot they will be purchased too CSA style boards never have the RAM board though so waste of money on ebay.

9mb is good for Dpaint anim brushes + digitiser
