[AQUARIUS] New Product: Aquarius 32K RAM Module

Recommended Posts

Here's a link to the (preliminary) instruction manual for the 32K Module. I hope to add more to this shortly, but this should cover the basics:

Very nice!

 

It may be messy to add this detail in the manual, but the non-S2 models will show 31037 bytes of RAM available.

... and Extended BASIC will show a different amount as well. That version of the manual is a "rough draft", so I'll soon be reworking the whole thing, and I'll be sure to include all this information.

True. For simplicity, you could stipulate that no program cart be inserted while performing the mem check. That would only leave the AQII owners with inaccurate info in the manual. Probably won't receive too many complaints from them... :)

As I couldn't decide on one color, I picked up some RGB slow rotating color changing LED's... any suggestions on a resistor value to use with it on the RAM cart?

Hmmm ... I wish I'd thought of that idea myself!

 

The supply voltage from the cartridge board is 5V, so the best value of the current-limiting resistor would depend on the forward voltage rating of your LED. The easiest way to find the resistor value would be to use a calculator like this one.

 

The LEDs that I used were rated at a maximum forward voltage of 2.4V to 3.4V (depending on the color), and a maximum forward current of 20mA, so I used 82Ω resistors for the blue, white, and green LEDs, and 150Ω resistors for the red and yellow LEDs.

Thanks! I'll have to bookmark that link!

The specs on the LED's I picked are 3.0v - 3.5v, 20mA... Which calc's out as 100Ω - 82Ω. Think I'm better off leaning towards the higher side of the range?

For that rating, anything in that range should be fine. Use whatever resistor you happen to have the most of in your parts drawer. :)

 

The worst that can happen is that, with a larger resistor, the LED doesn't shine quite as brightly as it could.

Hey, that's pretty good! I need to go back and revise that manual at some point (mainly to add some more technical information), but in the meantime, it's nice to see it in print!

I really need to invest in a color laser printer at some point. Even a relatively inexpensive consumer model would make it much easier to print proofs of my manuals.

 

Just out of curiosity, what type/size of paper are you using?

Yes, of course! The "collector's editions" with the LEDs are sold out, but I can still supply plenty of the black-shell editions. Just send me a PM and we'll take it from there!

How many special editions did you end up selling?

All of them! I have a very limited quantity of transparent shells, so a run of thirty "collector's editions" seemed appropriate for the Aquarius's 30th anniversary, and all thirty of them sold.

 

(There are actually 31 in existence, since I also made one for myself, but all the rest use black shells.)

is it still available?

Absolutely! I've been replenishing my stock, but I'll be ready to start shipping again soon, so anyone interested is more than welcome to send me a PM.

Just a quick note to let everyone know that, after being unavailable for several months, the Aquarius 32K RAM Module is finally back in stock again! When I started this project, I had no definite idea of how much demand there would be for this module, so I kept my inventory fairly low. Somewhat to my own surprise, I ended up running out of my original run of boards, so I had to order more! I've received several inquiries in the meantime, so for anyone who's been waiting, the 32K RAM Module is indeed available again, and at the same price: $30 plus USPS Priority shipping. Of course, the Aquaricart is still available, too, so send me a PM if you're interested in either or both of these cartridges. As always, thanks very much!

There was never a disk drive?

The only "official" Aquarius disk drive was the Quick Disk System, released in very limited quantities, which used double-sided 2.8" media (100K total per disk).  Here is more information on the Quick Disk, and here are some pictures (courtesy of Martin v.d. Steenoven) of one of the few remaining Aquarius Quick Disk drives in existence.  The Quick Disk System interfaced with the Aquarius through a cartridge port adapter, which also added a few disk commands to BASIC.  There was also a similar third-party interface designed for the Commodore 1541 disk drive, with its own disk commands.  Both of these modified versions of BASIC are available in the Aquaricart collection.

Last week I received both the Aquaricart and 32k RAM modules from @jaybird3rd.
 

Thank you Jay for excellent packing and swift shipping. Everything arrived in working order. 100% customer satisfaction!
