My quest for cheap RAM has ended in my own backyard.
Multimedia Design (916) 372-3822
1Mbit x 4 80 ns scram ZIP's : $35 each, or $280 for four megabytes.
Compare this with $45-$65/chip that other places have.
These folks are a tiny little VAR that puts together high-end Amiga
systems for professionals, mostly for video applications, though they
put together CAD systems, too. I asked, and it sounds like they can
take orders over the telephone and ship them, although this isn't
their usual modus operandi.
Boy are they going to be surprised.

I am kinna confused here, could some one please explain the A3000 memory situatin to me... I know that it can have up to 18 Megs on the motherboard, but it can also have 6 (?) Megs, what chips are what what is this 256 X 4 and 1M X 4 about, zip? Scram? huh? 80ns, no wait? I am confused... Basically, If I want to get 18Megs on the A3000, do I have to buy them in 4 meg increments or what? Why? How much are they? Why is the sky Blue and Saddam Stupid?

I'm going to write it up (when I have some time) and put it in the frequently asked questions in comp.sys.amiga.introduction (unless someone else wants to). To cover the basics, though: The 3000 has separate areas for CHIP and FAST ram. There are two banks (logical slots holding 8 chips apiece) for the CHIP ram, each of which holds 1 megabyte. This means you get up to two megabytes of CHIP. The FAST ram side has four banks. Each bank can hold either 1 meg or 4 megs, depending on the kind of chips you use. You can not mix up the types. All the banks that have RAM in them must have the same size of RAM. This means that the 3000 has maximums of either 4 or 16 megabytes of FAST ram on the mother board, depending on what kind of chips you use. Counting both the CHIP and FAST ram together, this gives maximums of 6 or 18 megabytes on the motherboard. Note, however, that the 3000 can handle a lot more than that via the card slots. You should not expect ram there to perform very well, however. It is much faster to get to ram on the motherboard, especially if you are using 16-bit ram cards like you find in A2000's. Using one of these will slow down your 3000..... Dan Zerkle zerkle@iris.eecs.ucdavis.edu (916) 754-0240 Amiga... Because life is too short for boring computers.
