Re: Matchbox sized 6502 / Z80 / 6809 Co Pro

Is this board destined for Andy (anightin)? He has a Xilinx Programmer so will be able to update himself in the future. Yes it is. I can hold of sending it and update it again if he needs the very latest. I am hoping to become a bit more active in the Acorn scene again in the next few months. I onl...

Re: Wanted: Matchbox sized 6502 / Z80 / 6809 BBC Micro Co Pro

1570026656835711141272700625793.jpg Hi, Sorry for the extended delay but I have prepared your Copro. It took me a while to find everything both physically and how to do the update. I paid £94.95 for two in 2015 so half that will be £47. If you PM your address then I will send my Paypal details and ...

Re: Matchbox sized 6502 / Z80 / 6809 Co Pro

I am updating a CoPro! I am preparing one of my Copro's to pass on to another forum user so it was time to update my unit. Well I have not done that in a while. Oh boy it took a while to assemble all the physical bits but then I had to do the update. Well it was hard to find the information so for m...

Re: 3D print Acorn Atom case

I have just found this thread. I was wondering if anybody had designed a Laser Cut Acrylic case for the Atom?

I am interested in this as there are a couple of Recreation threads in the Atom section and the case and keyboard seem to be bits needed to create a "everything new" Atom.

Re: Micronova Systems Limited PCB CAD

Yes it was in BBC Basic but had some sort of protection which I had to break. I had to do that as I found the package could not handle shrink dips which I had on my design!

Micronova Systems Limited PCB CAD

Has this program been archived anywhere.

I used it back in the day around 1986/1987 and I modified it to improve it!

I will try and dig out my version to archive at some point!

I had this program running on the 32016 second processor which allowed much bigger PCBs to be designed!

Re: Atom 2k18 ?

My only comment is that I am surprised the 3.3V plane does not run under the entirety of the FPGA board as there is nothing running at 5 V there. The highest speed and most critical part is the fast SRAM right under that board.
