Item price will be increase

NOTICE / 2021. 5. 31. 11:15

Dear friends and customers.

Thesedays, I have problems to obtain parts for my card/board.
I used old parts if it obsoluted for long time ago but, some parts still available to buy new one.
Thesedays, I wanted to order parts but, I very supprices at
some semicondor parts price much increased not just +100%.
Someparts just +70% but, some parts +300% or +400 even +1000% is market price... ;(
I want to provide better price but, it is too much increased..
So, I decided to increase item price and some products are not avialable even now due to I ordered from better priced place but long delivery place.

 

Anyway, when I have good priced par ts, I will adjust  the selling price.

 

Sorry for this.
Regards;
Ian Kim


Updated: I found better priced parts and I will reduce price some.

Dear Friends and cutomers,

 

Below is the speed test screen in the scroll game.
In APPLE II, it is  the best scrolling screen on the game.
(The sound was not recorded, but there is sound as well)

https://youtu.be/5UQ8SOpKwig


On the Demo, It shows the screens at 7.16Mhz, 3.58Mhz and 1Mhz respectively.
If you compare, you can see how much difference there is.

if you play the game, there is a sound of shooting a gun, and the sound of dropping a bomb and being detonated.
But, I'm not sure what is the purpose on game.
I guess that It doesn't seem to be made properly due to speed problems.

If made for accelerator cards, a much better screen and smoother look of enemies and friendly planes and  the blast planes.

If I think to make similar as this, set the CPU to 3.58Mhz and reduce the scrolling speed a bit, and handle other things more, 
It woulbe be much better game appearance would have been possible. Of course, if the speed is based on 7.16Mhz, it will be possible to drive more spare CPU power.

If I try to make a game later,
I would like to make a game that supports a merking board or a music card on such a scrolling screen.
It is almost impossible before the accelerator.

With A2 Turbo, programming with Apple 2 will be more fun. 

Thanks
Ian Kim

Dear Customers and Friends,

I'm making an economical version of the A2 OverDrive accelerator.

Now all functions are working very good.

 

The A2 OverDrive has a lot of features, but a simple one would be a good choice, and a better price would be very helpful for many APPLE II fans.

Among the features of A2 OverDrive, only some of the functions of acceleration and memory cards have been imported.

What are the features?
0) Accelerator for APPLE][ and APPLE //e
1) Accelerates the MAIN and AUX areas
2) Accelerate all BASIC programs
3) MAIN 64KB and AUX 64KB
4) Speed steps from 1Mhz--> 3.58Mhz -->7.16Mhz by external simple toggle switch.

It has full memory so, APPLE][ user no need 16KB memory card with it and virtual 64KB AUX memory can use even on APPLE ][.

I'm hoping for a lot of people using it and then software developers may optimized their new programs for the Accelerator and  smoother graphics and sound could expected.

This card looks similar as under and not very different.

Under screen shot is on APPLE //e

 

Below screen shot is on APPLE ][+ 48K but, became 64KB Main and AUX 64K detected.

Please be aware, APPLE ][+ doesn't have own 80col display function nor DHGR/DGR and 
A2 Turbo doesn't make this function on APPLE ][/+.

Watch this how it works!

youtu.be/at6EreUgEc0

 

The target price is lower than $100

And expected availability date will be approximately 3 weeks later.

 

If you have any concerns, please let me know.
Thank you.

Ian Kim

 

** If you want to see how works on program? please let me know the name of program and then I will test it and upload the working movie.

 

** It doens't make your APPLE ][/+ to APPLE //e even AUX emulation supported.
