Retro Chip Tester programmer

[CoS72]

Hi Everyone,
I have just finished building a retro chip tester ... It is already at V25 and bought from Retro Lemon RCT ... it works great but i need to update it to the latest version. I bought a DollaTek compatible Atmel AT AVR ISP MK2 from Amazon. I have had a nightmare trying to get windows 10 to recognise the device. I have watched many YouTube videos like this one .. Arcade Components and a lot of posts talking about drivers from ZADIG etc ..

What devices do you use to update the RCT ?

Thought id post an update on this in case anyone runs into the same issues with this process ... I searched and tried just about everything but just could not get Windows to correctly recognise the device. The ISP i bought was the DollaTek Compatible Atmel AT AVR ISP MK2 and it states it is compatible with Win 10 and Microchip studio 7.

In the end i decided to cut my loses and ordered a different brand ... Waveshare AVR ISP Programmer - I didn't have to do anything - Windows recognised the device immediately (drivers from MSv7 probably) and using Microchip Studio updated the RCT with no issues.

Maybe its a defective device or something else .... but my advice would be just buy the Waveshare one !

I've not tried updating mine yet, does what I need as it is - I got the Pololu USB AVR Programmer v2.1 as it is listed in the manual.

The cheapest option is just use an arduino. Program it as an arduino isp, and use this to flash the rct
