Naked Kaypro 16 400 Hz so Kaypro has added a small var iable capacitor across the master crystal They can simply tweak the clock until flight simulator generates color If you are holding your breath for a fully com patible system that runs faster than the PC or XT you re going to be waiting a long time It s not compatible while it s running faster Keyboard The keyboard Kayboard is IBM right down to the lousy return key Sorry but you asked for compatibility and you got compatibility compatibility compatibil ity compatibility I O Board The second board plugged into the motherboard handles the disk control serial and parallel interfaces as well as providing space for another 128K of RAM there are sockets for 640K total The serial connector is a nine pin db 9 and the parallel connector is a standard db 25 the type that is used for the serial interfaces on the Z80 Kaypros Con fused It appears that they chose these connectors in order to save space Video Board The video board is a real bonus You get full color graphics with both compos ite and RGB Red Green Blue color out put to an external monitor The internal monitor displays the standard B amp W graphics The board is capable of twice the reso lution of the standard IBM but alas they chose compatibility Anyway IBM reserved memory space for both B amp W and color graphics Kay TERE EEE EE S EEEE a E EEE E TEE E E E nd
5. The SASI is just like any other parallel port except it has a few extra control sig nals that must behave in very specific manners A parallel printer usually re quires nothing more than a strobe line a ready line and eight data lines These can all be easily derived from SASI sig nals During the following discussion please refer to page 3 of the Slicer sche matics page Connectors 2 and pages Theory 5 and Theory 7 SASI Hardware The data lines are already well de fined as is the ready line The strobe can be manufactured using the SEL signal and a software timing loop We must al so connect the SASI I O input to some output on the Slicer so we can control whether the parallel port is an input or an output port this function is usually controlled by the device at the other end We will use the SASI RST signal to control the function of the port The RST output will be wired back to the I O input This gives us a pinout on the 50 pin SASI connector that looks something like what you see in Figure 1 see con nectors 2 in Slicer manual This configuration may be a problem if your printer actually uses the Centronics RESET signal If this is the case there are two alternatives The first is to con struct an RC circuit to slowly bring the RESET line on the Centronics port from 0 to 5 volts at power up The second alter native is to use the SASI RST for the 34 Micro Cornuc

A big problem of interfacing the PSGs with the Z80A running at 4 MHz is that the I O read write cycles and the data bus hold times are not long enough to meet the GI specifications What this means is that when the Z80 is doing I O the PSGs either Don t see the data long enough or can t supply the data fast enough The term data hold time re fers to the amount of time the data bus retains valid data after the end of a ma chine cycle For the Z80A this is about 70 nS The PSGs expect it to be 200 nS To make the I O cycle longer is simple continued on page 65 Micro Cornucopia Number 22 February March 1985 63 T FOR THE BEST OF US pme IL THE CYPHER IL A COMPLETE 68000 amp Z 80 SINGLE BOARD COMPUTER SYSTEM WITH ULTRAHIGH RES GRAPHICS 68000 amp Z80 DUAL PROCESSORS BEST OF BOTH ULTRA HIGH RESOLUTION GRAPHICS 128K WORLDS PROGRAMMABLE UP TO 1024 X 1024 RESOLUTION 256K TO 1 MEGABYTE MEMORY 4164 OR 41256 DRAM NEC 7220 GREAT FOR CAD SYSTEMS DOUBLE DENSITY FLOPPY DISK CONTROLER 8 OR REAL TIME CLOCK MULTITASKING CAPABILITY 5 WD 2793 TWO CHANNELS OF D A AND A D 12 BIT DMA CONTROLLER FOR FAST see TRANSFERS TO RESOLUTION MUSIC ROBOTICS FROM VIDEO MEMORY INT 8237 16K TO 64K MONITOR EPROM 2 RS232 SERIAL PORTS ZSIO 4K TO 64K STATIC RAM 24 BIT ADDRESS MANAGEMENT FOR Z80 PROGRAMMABLE BAUD RATE GENERATOR 4 LAYER P C B 9 X 14 PARALLEL ASCII KEYBOAR
