Quickloader Reboot

Some of you will be aware I started work on designing a more compact verison of the original Quickloader card.

Macnoyd did the hard work and created a schematic of the original card for me to work from.

With that schematic I put in a solid 3 hours work created a new smaller, low chip count design  and board layout.

Well tonight I kicked in another 5 hours and wrote the GAL rules that will pull it all together and make it work.

I also just ordered prototype boards, so in a week I will know if  it works.  Once I know thew design works I'll order a production run of the new boards with gold edges.

 

There is a plan to write some software that will take the eprom images created by the original utilities and write them into the flash ROM on the card without the need for a universal programmer running on a PC.   Eventually that proram will be included in the standard ROM image.  But until that utility is written a programmer will be needed.

 

This is what the protoype card looks like. Its quite small at 56mm x 66mm.

The prototypes are complete

The prototypes are complete and waiting on DHL pickup, so I should have them on Monday.
If all goes well then I'll order a production run of 40 cards. So we are probably a week or two away from production cards being ready to ship

This is what happens when you lay out a board when you're over tired ...

So much effort to wire a prototype by hand. I'd rather spend $30 and get boards made

But in a sad sort of way, I actually enjoy it.  Gives me total freedom with a little bit of semi-instant gratification.  ;-)

I found some time tonight to do a little more work on the prototype and I believe I have overcome the timing problem preventing the cards flash ROM being programmed by the Apple 2.

Code written to put the chip into command mode and retrieve the chip ID now works.  Being able to put the chip into command card is needed to be able to issue erase commands and write commands.

Now all that remains is to write the program to allow user updates to the cards ROM and to tesat it in more machines to ensure it is stable and fully compatible.

Great! Interested ...

Great!  Interested to see your result.  I'm currently working on the Flash ROM code now. (going a bit slow right now)  Maybe at some point we'll be ready for a whole new product intro.

I think there's great value in an "instant load" card like the QuikLoader.  Bootable SSD's are great but this card does have the advantage of instant selectable DOS plus 2.5 times more "instant load" applications over a floppy emulator.

Looking forward to your result.
