Picasso II Memory

[EdKing]

Does anyone know what type of memory the Picasso II graphics board uses ?
I want to upgrade my board to 2 Meg.

1 or 2 MB 45 or 60 ns DRAM
1 MB (eight DIPs) soldered to board
eight DIP sockets for additional 1 MB
accepts 256k×4 DIPs, 45-80 ns

Hope this helps.

Thanks for the Info, now I know what to look for.

Hi EdKing,

I sell them.  How many do you need?   :-D

Oh, BTW... your Workbench 2.1 disks were shipped last week.  Enjoy.   :-D

Hi Etho,

Are you sure about the speed of the DRAM?  The fastest I have ever seen these 44256 DRAMs is 60ns and these are very rare.  80ns and 100ns are the more common speeds for these DRAMs.    :roll:

Alot of the old PC video cards for ISA slots, use drams as memory expansions on the cards..  find some old discarded video cards s3, siruslogic, tsenglabs etc

If the ram on these is socketed (which alot were) rip'em out and check the ram access speed.

If similar to whats on your picasso.. enjoy :-)

Hi Azryl,

That is where I find a lot of the ones I have.  I find these DRAMs at my local Goodwill Outlet for about .35 cents per video card.  There is usually 8 of the 44256 DRAMs on each video board.  I sell the 44256 DRAMs on eBay for an average price of $10 to $20 per 8 chips.  So, as you can see I make very good profit on these "rare" memory chips.   :-D

The 44256 DRAMs are also used in the A2091 SCSI Controller board, the Amiga 2000 and 500 motherboards, the Atari Mega ST motherboards, and various other hardware and boards.    :-)

After the last fiassco of ordering something from you, thanks, but no thanks.
I got the disks, I thought I was purchasing originals, not copies.

Thanks for the tip, I have a few old boards around.

Hi EdKing,

I got the disks, I thought I was purchasing originals, not copies.

I would never sell the "Originals" of Workbench 2.1 for only $12.00 plus s/h.  Workbench 2.1 is the rarest of the Amiga Workbenches and is now going up in value with "retro" collectors.  Consider yourself lucky to get a professionally produced copy of the originals on high quality Sony disks for only $12.00.  I paid almost $50.00 for Workbench 2.1 with the boxed manuals, in new condition.  I can buy a brand new Workbench 3.9 for only $35.00.  So why does a used copy of Workbench 2.1 sell for an average amount of $40 to $50 on eBay?   :roll:

@DoomMaster

So you're selling pirated copies of AmigaOS aswell?

You damn pirate scum!

@BoingBoss

If you look at my original request, I asked for a set of WB2.1 disks, not copies.
I could download pirated copies from the internet. Like I said earlier, I wish I
had known what a clown you were, I would never have sent you the money.

Once again, thanks for the tip, I found a few graphics boards in my computer
junk and got enough chips to make my Picasso II a 2 meg card.

Hi EdKing,

If you look at my original request, I asked for a set of WB2.1 disks, not copies.

That's right, you asked for a set of WB 2.1 disks and that is exactly what you got.  You did not say anything about them having to be "original disks".  If you had, I would have told you sorry I can't help you.

I am not a "clown".  You just need to be more specific in what you ask for.
