Hello, All
Initial data - “yellow” Scorpio, kindly exchanged by me from Evgeniy7 for
commensurate equivalent of beer... :v2_cheer; Without; bells and whistles. Standard -
Prof-ROM installed.
This sad story began with the fact that I dropped tweezers on a working
Scorpio.... :eek;
By; using the exclusion method, it was determined that I had burned the ROM.
There was a suspicion that the cribs were rattling, since Zhenya made the legs a little short
adapter
In general, I soldered another page arbiter - the same picture as with Zhenkina
fee.
You pull off the ROM - beautiful vertical stripes, as they should be
in the absence of ROM.
Moreover, in both cases - if the adapter is in the crib of the standard ROM, but in
The scarf itself has no ROM, so there is no adapter inserted into the crib
Scorpa....
That is, the circuit does not transmit any signals, and does not spoil anything...
You insert the rum and the color music begins.
Signals are present on all legs, that is, with a probability of 100%
The page arbiter works fine.
You raise the 32nd leg of ROM (we cut off the power, put it in a “suspended” state) -
again a beautiful mmmattress.
Morality is fucked up. :confused;
So?;
How to check it? As I understand it, it is possible to exclude the page arbiter, that is
force you to read only ONE page. Let's say Vasik 48.
Remind me how to follow this monotonously, otherwise I counted here - my lastThe Spectrum was brutally tortured by me and given to my younger brother 14 years ago...
:D

Hello, Mikka_A
If you're here, call. I take a "spare" ROM home with me.

but it’s no longer necessary.
I fixed everything.
The track on the board (power supply) burned out under a small component in the cascade
