modern TTL/Logic-gate/74xx

The Senate:
The old multi function peripheral chips they used in 8 bit computers come to mind since they still make some of them. For example the 6522 VIA has 2 16 bit timers, an 8 bit shift register, and 2 8 bit parallel I/Os.

Each of the CPUs had there own group of peripheral ICs made to complement them. Some are still manufactured like the 65XX family in DIP and SMD form.

RC2014.co.uk seems to have an inexhaustible source of Z80 and related peripherals.  I have at least 3 of his systems (I tend to lose count of this kind of thing) and they are quite fun.  I especially like the Full Monty version running CP/M.

Well the OP said they didn't want to hunt around or salvage old obsolete logic chips, so CPLD/FPGA is the natural thing to come up when the other viable option is shut down. The 74xx series is 40-50 years old, the fact that so many of them are still available today at all is a minor miracle. I use the DIP parts to repair vintage gear but I can't imagine there are many going into new designs.

It's an impossible ask to prevent threads diverting off the original topic but in the beginners section people should exercise restraint.

In this particular case, it probably was for the best.
And my original question has been answered anyway. As a beginner, i very much appreciate the additional informations since i ended up buying a FPGA board (a proper one actually made for beginners, this time)
