Received this back in May of 2019. It has proven itself many times. Lots of tutorials explain how to burn a boot loader to the AVR and require many items. This is quite simple. There are only a few left. If you don't have one for your Arduino UNO, get it! It will help you greatly. I use it a lot with new 1284P's without the bootloader.

Easy to assemble; works as it should

For TMS9918A Video Card Kit for RC2014

The board was easy to assemble and it works as it should. There were small details incorrect re. jumper settings, but the ready availability of _other_ design references made this easy to figure out.

I was delighted to have easy access to this period-correct graphics for the Z80 architecture and thankful to the developer for his design initiative and _especially_ for sharing with the community.

Nice set.

For z80ctrl Card Kit for RC2014

The order went a month to Moscow. Assembled in 3 hours. I downloaded the firmware via CP2102 without any problems.

Best. Kit. Ever.

For z80ctrl Card Kit for RC2014

This kit has revolutionized my use of RC2014 hardware: it can do so much. Essential for really getting the most from your retrocomputing hardware, and very flexible: at the moment, mine is connected to a standalone Forth-based computer, and I can use it to load and save the entire contents of RAM to SD Card, as well as running debugging sessions. It also replaces dedicate ROM boards, clocks and even a serial card. Get one.

A must have module

For z80ctrl Card Kit for RC2014

This is one of the modules you just need to have for RC2014 builds, specially if you like to experiment more. Easy to build, quite fast delivery and quality components.

Great product.

For 10x10 RGB LED Matrix

Works fine. Bright display. No flicker. Easy to program. One assembly hint: to help get all the LEDs at the same height - solder LEDs in each of the 4 corners first at the exact height desired. Thus you have a reference for filling in the square.

Glad to Have this Board!

For Programmer Shield for AVR DIP40

It makes my job easier on programming a large number of chips. Plan to get the word out to my co-workers.

The z80ctrl is a brilliant product for the experienced user.

For z80ctrl Card Kit for RC2014

The z80ctrl is a system controller that enables running different 8-bit systems.
I am pleased with this module, but I have to warn potential buyers that this product is not for beginners.
I have successfully assembled and running the module, but it is a bit too complicated for me.
The product is well documented but aimed more toward experienced users.

Fast shipping

For SN76489 Sound Card Kit for RC2014

Fast shipping and as described. Only hint I would offer is insert the left sound chip first. One of the pins broke on one of mine (an issue with the IC and me, not the kit), but left is used for mono output which is most likely to be used anyway. I had a spare and am in business.

A great idea and implementation!

For z80ctrl Card Kit for RC2014

This card adds a lot of flexibility to the RC2014 system and can save you buying a clock card, a card for storage, and a serial interface card--all while given you more power than those cards alone would offer. Great support on the forum and a path to some interesting upgrades over time.

Just what I was looking for...

For TMS9918A Video Card Kit for RC2014

Was interested in the RC2014 but wanted a real video card. This fits the bill. Shipped fast. Easy to build.
