I made it. nano8088

https://github.com/monotech/Nano8088
(Based From https://github.com/skiselev/micro_8088)

I don't have electronic knowledge, but I'm happily building a retro machine while recalling my childhood memories.
Thank you very much for sharing and dedicating your open source PC hardware project.

I successfully completed NANO 8088 about half of the time, but the error message below makes me sad.

I made it as below, is there any problem?

Replace with PN2222 => 2N2222
Replace with Faraday FE2010A => Proton PT8010AF
Install 6.5-30 pF trimmer capacitor as unclear product

Or, Is one of the AS6C4008 (SRAM) broken?
Please give me some advice.
Thx!

Curiously, if I pass the RAM check with ESC Key, the games run well. (Monkey Island, Indy3, Zeiliard...etc etc)

Well I have been trying to buy a set for 2 weeks - had a friend in Korea msg you and everything but no luck.

So I ended up ordering all the parts to build my own - really wish I could of picked up a set from you.
