공지사항

Dear friends and customers,

I glad to annouce another multi functioning accelerater for APPLE II.

It could provide a good capability on APPLE II system with faster BASIC speed, better memory and DHGR acceleration.

I spent some months to design and testing it and now want to receive order for internation buyers.

In fact, some month ago I already completed design and sold it several cards for local friends.

but, It took long time for international customers.
I don't have much good eyes now and then eveymonth feel little different and this card have very small parts and hard to make by hand. New card developing is hard for me.

Spending times and idear into new card.. it is an not just developing... it is an exploring in the APPLE II system.

When I bulding new devices, i really wanted make different than presents others.
I want to assign unique characteristics for my card and then there could be some special functions with it.
When I considered new features into my products, it desn't completed easy, always bring other technical issues.
Maybe I still don't understand some of WOZ machine properly....

I don't know how long could I design and make cards for friends....


I had rest some weeks and feel much better now..   so you can give me order to make yours now.


The A2 OverDrive have sevaral funny functions.
One is Digital output.. and we can play WAV songs with it (Ofcause,  It need a DA converter) 

High speed acceleration doesn't give other than the speed...
But, It bring the possibility for your APPLE II.
Faster running software will make other possibility for real time based game.. 
On the graphics, it could provide smoother faster more object can move at one time period.
But, all software functions... not hard ware addtions.. at least still now the accellerater card was as this.

 

For A2 OverDrive have hardware special functions.

1) interrupt generator
It provide IRQ or NMI interval timer interrupt. user can define the timing of interrupt. 
Hope to be used for multi processing and for event processing.

2)Slot memory
Sold memory area $C100-C7FF which are reserved for ROM on SLOT pheripherals.
A2 Overdrive has ability to override this area to own RAM location.
Hence the area can use for User's area ROM or RAM.
Also $C800-CFF0 area also can override it to own RAM.
It is one of my philosophy that if technically possible then try to make new&fun functions.

3) Digital I/O
Many of people wouldn't use it except sound module function to play the WAV (sampling) sound.
I provide it for H/W fun.
8bits Input and 16bit output.

Other small functions such as fixed interval reader, R/W memory speed adjust etc...
Some are provided setup value due to limitation on APPLE II to co-operate it but, others are for special functions those couldn' find other accelerators.

I'm making the English manual for this card and some are completed but, when you order and receve the card, you can have proper manual.

Other information are scattered on this site. just consider it as an  hide and seek game.

Please order this card for an engineer who want to make more fun devices for APPLE II.

I'm using SD MIDI ][+ Player while on my resting time.

From this version it supports MIDI system exclusive.

System Exclusive is depend on the MIDI sound module but, the default given module accepting and play better. Sound became smoother..

 

I think that I've done almost of all for MIDI player.

And I need to finalize this version. just left full testing.

 

Thanks a lot

Dear Friends and customers,

 

SD MIDI][+ Player using three timers of SD MIDI ][+ card.

And I had a report from a user who having some tempo issue.

 

Please patch your SD MIDI ][+ card as the photo.

 

It required 3 resistors (4.7K - 10K  is good enough).

And solder the resistors as the below.

 

This Location pins are not used but, it receipt some noise.

And the Resistors will pull down the pins and set it stable.

 

Thanks a lot

Ian Kim

Dear customers and Friends,

 

SD MIDI II+ Player did update for more functions and accurate play.

 

In this version, It used a Hidden reading method when it need more data from Disk and results having seamless polaying.

And user can select own Level meter char. by pressing 'B' and 'N' on APPLE II.

Playing tempo tuned more accurate.

Just have a time to watch how it's playing as under.

Dear Friends and Customers,

 

This version optimized some more for the Level meter and added on left as a channel indicator(?).

And level meter speed was incresed and good now.

It is the best what I can do with 1Mhz 6502 APPLE II.

 

Just watch the video.

 

Thanks a lot.

Dear Friends and customers,

It's up to what I've been working on recently.
The biggest change in this version is the player used as far as the hardware supports it.
It support a progressive bar (level meta).
It is very tight to support this in the 1Mhz APPLE II.
It was made using even the hardware timer and interrupt supported by the SD MIDI II card.
It is quite difficult to support it.
After a lot of trial and error, I finally decided to use a timer interrupt for simultaneous processing.

 

For reference, these progressive bars are the 16 channels of MIDI, from 0 to 15 from the top.
It seems that it is too difficult to handle this with interrupts in Apple2.
It's so hard that I don't want to bother you anymore.

It works fine with or without an accelerator card but, If you use an accelerator card, the CPU load is reduced, so the tempo of the sound can come out a little more naturally. This is because the load on the interrupt side is large.

Since you have to use PRODOS, you can't completely push the IRQ routine away, so this is the best what I can do.
If I increase the speed of the progressive bar quickly, the CPU load increases, so this is the last choice.

 

it is a thankful result with APPLE II.

Now I have waht I wanted.

 

Please enjoy listening.

https://youtu.be/kf90YvsiFVc

 

 

** Some more information **

- MIDI file format 0 is supported. Other formats can be played smoothly by converting them to MIDI 0.
- There is no MIDI file size limit. However, if the file is large, a slight delay may occur. This is sometimes canceled by the internal timer when a delay occurs, but in some cases, it cannot be canceled and may exist as a sound delay.

 

It isn't a freeware sorry bout it but, I will provide SD MIDI][+ customers for free.


Thank you

Ian Kim

    Hi Ian,

    Will you still working to improve the compatibility with Music Construction Set? The card sounds not quiet right in MCS.

    Thanks.

      Hi,
      This is a post about MIDI cards.
      You put wrong location.
      And You are maybe talking about SD Music Deluxe card.

      The compatibility for the MCS isn't easy.
      I will check when I have a time.
      Mockingboard emulation is really very complicated and FM OPL chips can't make the same as AY3-8910.
      Anyway, I need dig more to make more similar.
      Thanks

Dear Friends and customers,

 

 

A2 OverDrive is start to preparing PCB and parts.

I will order PCB soon and parts.. (parts price really very high now.. x3-x5 times becam higher)

Dear Friends and customers,


SD DISKII Plus emulate two FDD or two HDD and It has a good Menu drived image selector.

On HDD emulation, SD DISKII Plus work as block devices and supprt two 32MB HDD emulation.
It doesn't accept smartport function call internally.

I have some reports about non working HDD image(800k).
And I found that those are using smartport MLI without checked the type of device.

Boot ROM already indicated as a non smartport device but, Smartport call happed on some program without check type of device and failed to access on some HDD images.

Anyway, I decided to support Smartport call on SD DISKII Plus.
I'm learning for smartport fuction calls.

It have to both on ROMBIOS and Firmware on SD DISKII Plus.
It would take some time please wait for new BIOS.

Unfortunatelly, It might to be updated ROM chip.
It require a ROM writer to update with new code.

New ROMBIOS and firmware would be annouced when It finished.

What will be change?
1) Smartcall program(image) will work properly.
2) More HDD drives can use now it has two HDD but, more atleast 4.
3) More block size accepted max 8G.

No change on 5.25" FDD emulation 

If you have any question, please let me know.

Regards;
Ian Kim

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.

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.

A2 OverDrive revised

◆ Accelerator / 2021. 4. 28. 16:14

Dear Friends and Customers,

Recently, I ordered revised accelerator PCB.
I've tested it on CFFA3000 before and it wan't stable but now it solved on this PCB.

Due to phase timing issues, It wan't stable on CFFA3000.

 

I tested this card on below APPLE II models.
APPLE //e platinum, Works nice.
APPLE //e enhanced, Works nice.
APPLE //e non-enhanced, Works nice.
APPLE ][+ (Original) works and need to test some more.
APPLE ][+ clone model 6502!(?) Not stable handling DISK Emulator.

 

WAVPlayer V0.1 (only works with SD DISKII)

Little shows information of WAV file on D2:

I will test some more the added features.
If everything are fine, I could order commercial PCB.

'New Accerator will born'

Thank you very much.

Ian Kim

This is a good utility to start game on APMSX.

This image doesn't have ROM images and user need to mergy files on HDV but, not hard to make it.

And there are source code of the launcer.

It tested and works!

 

Thanks ballmerpeak,
