Cmos on Kay 256/1024

Hello everyone! Guys, does anyone know how to connect Glitch cmos to Kai 256/1024? Otherwise we have problems. We don’t know what’s wrong :( The computer doesn’t see the clock from any programs! The same thing happened with Profi. Everything worked on Pnetagon from the very first times! And one more request. If there is any information about Kai (ports, memory, etc.) won't you throw it? There is no need for a scheme, it is there. Alexander

Print it out and hang it on your wall: COMPUTER SYSTEM BUS ZX-Spectrum (ZX-BUS) ================================================================ System connector for ZS-Scorpion computers (manufactured by company Scorpion) and the KAY computer (manufactured by Nemo).

Позже Make sure you have a +12V power supply snowflake. Hа turbo snowflake (remote) snowmobilecontact. On the computer KAY but this contact is displayed clock signal 14Mhz. (3) -- signal indicating connection of ROM and ports Beta-Disk interface. (4) -- in the Scorpion computer this is also the clock frequency signal processor, and inverted and delayed signal /RAS manager of dynamic RAM (according to the scheme Leningrad). In turbo versions of ZS-Scorpion the signal is not synchronous with the processor clock frequency. B computer KAY this signal is not synchronous with processor clock speed and is inverted signal /RAS. The frequency is always 3.5Mhz. (5) -- the signal is available only in the KAY computer. This is the way out register 7FFD responsible for the ROM bank (basic-128 or basic-48). Can be controlled by an external device. (6) -- the signal is set to 1 when turned on turbo mode. The output is open collector type, that is the expansion device may be forced to shut down turbo mode. The signal is used only in KAY. (7) -- the contact is not used in the ZS-Scorpion computer, used only in KAY. Signals /CSDC, /IORQCE, /INT, /NMI, /CSROMCE and /WAIT have high output impedance and can be controlleddevices connected to the bus (expansion slots). In general, external devices should not use these signals to obtain any information, that is, for them it is outputs - for example, in the latest version of KAY the signal /IORQCE made as an entrance. A typical circuit on a computer board for all of listed signals: /CSDC_out /CSDC /IORQ /IORQCE /INT_out 300-600ohm /INT /NMI_out -------RRRRRR------ /NMI /CSROM /CSROMCE /WAIT_out /WAIT Sources on the left, signals on the right going to the expansion slot and simultaneously to the processor, ROM, input/output ports (located on the computer board) or other devices. /DCDOS signal can be used by expansion cards only as an input - it tells external devices that Only ports in the address space should be decoded Beta-Disk interface. Actually in the original version Beta-Disk controller it connected to the ZX-Spectrum as a board expansion, but no /DCDOS signal was provided. The /IORQ signal was connected to the controller, and to the board returned /IORQCE processed exclusively controller. CONNECTING EXTERNAL DEVICES TO THE SYSTEM BUS. ================================================================Some general recommendations: If the device should not respond when activated Beta-Disk interface send /DCDOS signal to the decoder addresses are on par with address signals. Never connect the /RD or /WR signal to the address inputs decoder if the device supports writing and reading simultaneously: /IORQ, /RD and /WR signals in the processor do not switch simultaneously and false triggering. The best option is a combination of IORQ+RD for reading and IORQ+WR for recording. To suppress the response of devices on the board (especially for the KAY computer) it is necessary to force set the /IORQCE signal to log. 1. when decrypting an address your device (read more about the address). In that case if the I/O port decoder has /RD or /WR signals are not used, it must be used signal /M1. The address in the device must be decrypted BEFORE THE ACTUAL REFERENCES TO THE DEVICE (determined by /IORQCE or /MREQ), especially when using /IORQCE or /CSROMCE to block devices on the board. Typical decoder circuit: DD2.2 DD2.1 +---+ DD1 /IORQ +---+ /RD --+1 | +----+ /MREQ --+1 | | +-- /readA0, A1...

If there is any information about Kai (ports, memory AS>, etc.) would you mind? You don't need a schematic, it's there.
