I made same effort to identify the ICs in the Kalibr.
Funny thing : D
The AD9218 is a 20 years old IC, if I want to buy it for cheap I need to soruce it from china
Not expensive, 13 dollar each.300 MHz AD converter, good for small handheld oscilloscopes.
Next one, gigabit controller.
It is a 20 years old product as well, suprise,there are few supliers outside of China.
Just type back to aliexpress or ebay the 88e1111.
Now, the most funny part, 18 mbit SRAM.
Just for reference, it is 2 mbyte, (+ parity), the typical Pentium class computers contained 512 kbyte of this ram in 1995.
I haven't found the introduction date, but it has to be around 2000.
There was a notice from the manufacturer in 2016 about the transition to 60 nm manufacturing process for these ICs : D
This monster requiring 130 nm technology, available from 2000.
Just to clarify, the challange to make exact copy of these ICs is to remove the cap with HNO3,make few picture and make copies of them.
Require same time to finetune the machines, but let say it is a side project for few bored engineer. If they have nothing better to do.
Economical reason doesn't exist to do this kind of project.
