Trying to reconstruct early computers of mainland China, attempt continued

The first day, 2022.8.19 ~ 2022.8.20

Guess what? Not a single goddamn person sent me something in the whole fucking one and a half year.

I've found some sources (mainly from Hungary) that confirms DJS-1 was indeed a M-3 clone. As for the computer itself, there's this English ver. page from Russian Virtual Computer Museum but just like half of the old books I've bought this page does not help one bit. Only the Russian version has barely enough information to reconstruct the machine.

The second day, 2022.8.20 ~ 2022.8.21

I downloaded a bunch of old books from the same virtual computer museum. Of course they are all in Russian, which I know none. This is going to be fun. (sarcastic)

The Sino-Soviet split lasted from the late 1950s to 1989, and Nixon visited CCP China in 1972. I think it's safe to assume that Chinese modelled (some of) the Soviet computers for the development of their own machines before 1972, i.e. the vacuum tube era & transistor-only era.

Somehow the museum has I got a hold of the description for M-2 but not M-3, which can probably be helpful if M-2 and M-3 uses the same input/output devices; they have different instruction sets.

The following week, 2022.8.21 ~ 2022.8.25

I completed the simulator for DJS-1. I will stop working on this for a while from now.

2022.9.26

It was found that:

Now it seems like DJS-050s are using Intel MCS-80 and DJS-060s are using Motorola 6800. After the minicomputer era China just went with the same CPUs as rest of the world.
