Amiga 2000 ram

The obvious question is "how much ram does it have installed?"

For 6.2 the stock configuration is 1MB chip.  For older (unmodified, typically Rev. 4.x boards), it would be 512K chip/512k fast.  It's a common mod to convert that to 1MB chip.

Add it through a CPU card or through just about any compatible Zorro II expansion card.  Also the Kipper2K cards that fit underneath the processor can add up to 8MB and an IDE/CF interface.  These are manufactured new and very reasonable-priced (compared to picking up a 20-year-old used card off ebay anyway, I suppose).

As a bonus, any additional RAM you add to the system will be true "fast ram", unlike with an A500 trapdoor expansion, which is "slow-fast" memory (in that it doesn't actually accelerate the system).

IF you're new to using an A2000, you can also look at the sigs of people in the forums and ask them what expansions they use.  Plenty out there for the ole' 2000's.

Ya, the  A209x SCSI controller that's in my a2000HD has spots for ram but I would have no idea where I could find any for it.

According to http://amiga.resource.cx/exp/a2091 the A2091 "supports 256k×4 (44256) chips, 120 ns or faster"

Putting "44256" into ebay pulls up tons of listings.
