Два конструктора в лоте.
1) ZX Spectrum Leningrad 48kb (modified board)
DIY Set for self-assembly of a retro computer, clone ZX Spectrum. Included are all parts.
Set for self-assembly retro computer, clone ZX Spectrum. Included are all parts. ZX Spectrum Leningrad 48kb (modified board). The diameter of vias is reduced to 0.4 mm and hidden under the mask
PCB covered with blue solder mask and silk-screen printing
A mounting field has been added for installing a tape reader unit on a circuit with K561LN2.
Added mounting field for speaker installation on the board
Added mounting field for power connector installation
Added pins for installing SMD tantalum capacitors on the power bus
Added pins for installing SMD components instead of pinouts
The diameter of the holes in the mounting fields is increased to 1 mm so that you can insert and solder the pin connectors or IDC connectors.
ROM chip now need to install one, for example W27C512
Video output for connecting to a TV via SCART is made on transistors
Conclusions 1 RU5-x (RAM) are interconnected to simplify the upgrade. Added mounting field for audio connector
Unused trigger leads pulled up on + power.
The 10K pull-up resistors for the Z80 data bus are replaced by a resistor assembly.
Contacts have been added to install a 2.2 nF Capacitor between pins 4 and 7 of the K555LE1 chip (setting the circle in the symbol (s),).
And also provided
place for a 560pf capacitor between pins 6 and 7 LL1
Added mounting field for installing a line-out connector
Some kit components may have different ratings to improve device performance.

2)ZX Tape Player (Tap Files Player
Short description: control of buttons (forward, backward, selection (start), exit (cancel)), format the card in fat16 (up to 2GB), power to the 5 volt circuit (connector on the dad-type board (.) - external contact minus, internal a plus). connection to the Spectrum is simple - through the linear output (2 outputs). We supply power, choose the mode (1,2,4 times the speed. If you use the speed of 2 kr. and 4 times the speed, then you need to flash the new Spectrum with new firmware, firmware I have, if the speed is 1x, then nothing needs to be stitched), selected a file, clicked the start ... the progress bar shows loading and the number of blocks, after the end of the file the download will stopA set for self-assembly of an electronic tape recorder for downloading TAP files into a retrocomputer, sold without an SD card ..
