Title: What card is this?
Post by: djkoelkast on July 24, 2004, 06:34:09 PM

Hi,

I've got an Amiga 1200 card but not really an idea what is is. It also has some (i guess 32mb because it sais 1mb*32p) memory on it.

Picture:

The memory is standard 72 pins SIMM (70ns) and is located on the back.

What card is this, why the on/off switch? what can I do with it and what is it worth? ;-)

It seems to be a memory expansion card with real-time clock and possibilty to add a FPU... I guess it isnt worth very much...

I dont think the memory on board would be 32MB, the 020 cant address it.

Ok so it comes without FPU and without battery so porbably not much worth indeed ;-)

thanks a lot

I dont think by adding battery and FPU would enhance its value very much... They are cheap... :)

That's actually 4MB of memory.  (1M x 32 bits = 4M of 8 bits.)

Crazy numbering systems RAM uses.  ;-)

Looks like everything else about the card has been identified.

You can put it in an A1200.  ;-)  The fast RAM gives a nice little speedup over a stock A1200.  But it's not worth too much in resale, as the cards with fast RAM and 68030 give a lot MORE of a speedup, and are fairly common.  Price also depends on region.

Well western Europe here ;-)
I also have a 68030 turboboard with FPU and 8mb but that is some strange memory, it is GVP so this was GVP specific memory or something, But i use that card and not the card I didn't knew what it was ;-)

GVP memory modules look like Simms but are not compatible.The good thing about GVP modules though is that they are really faster than normal Simms ... but also a lot more expensive and harder to find. If you are very handy, there seems to be a hack on Aminet to connect normal Simms to a GVP board ...

Bummer.  They seem to be worth nearly nothing there.  From what I've seen, maybe 10-20e?  It'd probably bring $30-40 in the US.

Yep.  The early GVP A1200 cards use special "GVP" simms.  The cards sure work well, though.  I wouldn't mind having my old GVP 1230+ Jaws back.  (Sold it with my 1200 rig back in the day to afford my A4000.)
