Hi all! The owners of this card, please tell me the marking of the memory chips, which is installed?

@e2e4, Спасибо!
Hi! I’ve only just learned about this project. I’m in awe (no pun intended!). Is there any chance you will produce more of these? Or is it possible to sell just the board schematics/eagle/whatever files? I have always wanted a Time Machine!

I think that it's possible to sell for you board, but problem one and big. How to send and how to get money.... Where are you from?
I would like to buy.
Hello,
Is this still available?
I'd be interested in a bare pcb if theres any left
I also would be interested in PCB or card.
I think project is over.... 🙁
No one is interested in continuing it from the creators.
If that's the case, kindly release all of the associated project files so that we may build our own. Thank you.
Hi, a few questions for those assembling yourself about BOM discrepancies - or maybe someone who has an assembled card can take a look at their card:
ptrz wrote on 2022-10-19, 20:36:ECAP C50, C51 should be 22uF x 50V. C40-C49 should be 4.7uF x 50V (note for PCB rev. 1.2.1) The developer has probably already fixed this in BOM.
Is this still the case / confirmed? I see the BOM has not been updated (in Google drive nor att vccollection.ru) . The BOM says 4.2µF for C40-46, C49-51 and 22µF for C47, C48 (REV 121).
Also, R6 is listed as 91Ohm but the part number is for 93.1Ohm. This probably doesn't matter that much as the values are so close to each other ... but which one is correct?
Also, anyone adapted the RAM to something more modern? It's not easy to source 4M4 (I believe I can do it) but some Frankenstein adaptation to something more easily available would be welcome.
Also, GAL seems to be a bit difficult to come by and programmers are expensive.
