Hello, DR ZX ARE THERE MANY SUCH nonames IN NATURE?

Hello, DR ZX The lack of quartz is not that uncommon on early 90's clones. There were quartzes back then expensive and instead of them (in particular in Leningrad) they sometimes installed ceramic trimmer capacitor. Of course, there's nothing good about that there was no solution. I ran into such savings back in the late 80s, when one of the assembled in this way stopped loading normally programs copied on other computers. LC is although more stable than tuning capacitor, but there is also a risk of the frequency drifting away over time. DRZ> Or maybe someone remembers or has seen a board with this arrangement DRZ> microcircuits? I will also list the main microcircuits located on the board Regarding the method of determining what kind of clone, I have already published information ["http://zx.pk.ru/showpost.php?p=24406&postcount=2"]on the forum. If photo problematic, you need a complete list of microcircuits, and not just

. DRZ> and on the board it was written “ELEMHTOB side” DRZ> and there were no more inscriptions on the board. Funny inscription, apparently, the board distributors did not have a localization tool for P-CAD. DRZ> ARE THERE MANY SUCH NONAMES IN NATURE? There are only a few nameless clones. The reason is that, a new clone or just a newboard, this is a labor-intensive project, and almost never got by without a name. The exception was boards based on 1515ХМ1 (T34), which were designed for different body, but in an almost identical scheme. And even then computers with such the boards received names. Without a name it was hard to sell them. Just feel it yourself in the role of an inexperienced buyer when in front of you: on a Z80 with 16K ROM and 48K RAM or a personal computer with a proud name E even in completely identical cases and for the same prices same money. Therefore, with rare exceptions, determining the name of the clone and searching for the scheme is It's just a matter of time.

Hello Conan Here is a New Photo Using a phone (Irda Got it!) The quality is certainly not Well look: In a day there will be a whole list of microcircuits.

Hello, DR ZX Very reminiscent of the NPO NORTH computer, I had something similar lying around somewhere. Because The wiring is factory, but buggy. Although... maybe I'm wrong.
