NAND? 74126 1 quad tri-state bus buffer 744075 1 triple 3-inp. OR gate 7486 3 quad 2-inp. XOR gate 74132 1 quad NAND Schmitt trigger 74163 1 presettable 4-bit binary counter (sync. clear) 74138 2 3-to-8 line decoder 74629 1 dual voltage controlled oscillator 74259 1 8 bit adressable latch 74367 1 hex buffer tri-state 74595 4+ serial input shift register 8 bit 74166 1 parallel load 8-bit shift reg. 74191 1 presetable up/down binary counter 744040 1 12-stage binary ripple counter P2114A 3 512 bytes RAM, as 1Kx4 bits idt 71256 3 32k 9ns SRAM mc14011 4 quad 2-inp NAND gate (CMOS, 4011 alias) mc14040 4 12-stage binary ripple counter (CMOS, 4040 alias) mc14490 1 hex contact bounce eliminator (CMOS, 4490 alias) mc14512 2 8-input tristate multiplexer (CMOS, 4512 alias) 4001 1 Quad 2-input nor gate 4013 2 dual d flipflop 4020 2 14-stage binary ripple counter 4027 1 Dual J-K master-slave flip-flop 4056 1 BCD to 7-segment 4071 1 quad 2-input or gate 4073 2 Triple 3-input and gate 4081 too many quad 2-input and gate I think my MC14000s may be related to an MC14500 somewhere, but I can't look for it right now. That would be very interresting!
Hi Dylan, thanks for liking and following the #Isetta TTL computer !
