Great design flexibility and value, good build instructions. Went together in just over an hour. Only issue - what connections are supported via J4 and J6? Can't tell from documentation. I am guessing that J4 is the RS232/TTL interface and J6 is for firmware upgrades, but can't tell that from support docs. Should be included in instructions to reduce any confusion..

Very good product with non exhaustive documentation
Terminal is very good (better then original Geoff's one), very easy for assembling and has worked for the first touch. The list of supported ANSI commands is unfortunately missing.

Thank you! The list of supported ANSI sequences can be seen here in the source code https://github.com/petrohi/terminal/blob/8121ca94f40e7f40e53e7e188bf5afd0d014b1b7/firmware/Terminal.X/terminal_uart.c#L1532
A great quality little kit, soldered it together in couple of hours without a problem, regardless of my low soldering skills, and worked right away. The firmware is top notch too, quite impressive. Many options, still have to find out the right combination to make it work with my 9995 SBC. But the main reason I got it is to help with FPGA hobby projects to free up space that would be otherwise be used for text-based VGA controller + memory: https://www.youtube.com/watch?v=eGSghj2WLYs&t=27s
If you are looking for an easy-to-assemble and inexpensive ascii/vt100 kit suitable for basic soldering skills then this will meet your needs. Everything you need is in this kit. Good quality connectors (Amp) included as well. You’ll also need a ps2 keyboard which are in abundance on eBay for <$10.
The terminal adapter works perfectly. Power on is instantaneous and behaves just like you would expect it to. Some of the gaming graphics are not displaying but that might be me (there is documentation on on the Geoff website explaining the supported graphics situation ) - for all regular stuff you should be fine.
Peter was very helpful and super-responsive when I had various questions ...not to mention an embarrassing soldering crisis 😎.
Currently I’ve mounted the terminal adapter on a small piece of wood but will be put in in a plastic box when I find one the right size.
Good product. The board is a different size/layout than the original article, but after a little searching, found the layout photo at https://www.tindie.com/products/petrohi/geoffs-vt100-terminal-pcb/. Didn't really need it, but it was useful to have.
Recommendation1: Only difficulty was getting the 3.3v voltage regulator installed. The terminal pads really need to be spaced a bit further apart to prevent accidental solder bridging. There's plenty of room to do so on the board.
Recommendation2: An easily made modification (actually, just a sentence in the instructions) is to use extra strip-pins (three sets of two) in pin strip into the color pads so that different (single color - red, green or blue) can be easily changed/selected rather than solder bridging a fixed color.
It went together easily, tested out OK immediately and is now in use.

Thank you for kind words! Please allow me to comment on your recommendations.
1) In the new version of PCB I changed voltage regulator footprint to be more convenient for soldering. Here is the picture of new terminal pads:
2) Indeed I should be providing better instructions! Kit includes pins and jumpers to make color easily configurable. Here is how it looks:
The super high quality kit went together easily and quickly. The PCB is very high quality and no problem soldering all the parts on. The only parts change I made was to the header for the Rx Tx signals, I used a locking header and polarized mating connector to ensure correct orientation. Dont forget to bridge at least one pair of pads that select the color of the displayed text! That info is left to the student to figure out, so one star off documentation (which is the website).

Thanks! I am working on the v2 of the PCB, which will have jumpers instead of solder bridge for RGB selection.
Can you point me to the locking header you mentioned?
