Excellent Product! It works in the USA too!

For 32 x 64 VDU PCB for 65C02 SBC

I am very impressed with the product. I am currently running on and HDMI monitor via an Amazon AV2HDMI adaptor($US15). The display is stable and crisp. Much better than what you would ever have gotten on a TV through a modulator back in the day. I originally used 74123's but I ended up using 74HCT123's because I was getting a little jitter, even though the image was correctly centered on the screen. I am delighted with the result.

Hi Harold,
I am so glad you found my VDU PCB design suits your requirement. I like the idea of using 74HCT123s and will add a note to the product page to reflect your observations.
Many Thanks for the review,
Kind Regards,

Paul

Excellent product, board quality is superb.

For 6502 SBC Printed Circuit Board

I was pleasantly surprised that this board is available.

I have purchased a stack of boards to build up replica Ohio Scientific C4P-MF and C1P/Superboard II systems. It is really handy to have a known going, working gizmo that is flexible enough to connect to other stuff.

In addition there are enough add-ons PCBS from Hobby PCBs to make this little system an end in itself.

Assembly was straightforward, The only issue I had was the switch circuitry. The circuit shows +5 and the centre pin connected. That was a connection I had to make myself. Not a major issue. I intend to acquire the rest of the modules in the series and enjoy the trip down memory lane.

Hi Harry,
Thank you for your review. I'm sorry you had some issue with the switch wiring. I have updated the web page in light of your comment to make it clearer how the switch position is numbered.. 2 & 3 connected to +5v and 1 to the ICs.
Kind Regards,
Paul
