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

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.  ;-)
