If anything that got worse as clocks got higher, but there is more abstraction in terms of things like tooling to help you get around that. An auto-router from the 80's wouldn't stand a chance to route a modern computer motherboard, essentially every trace is a transmission line, so while nominally it is all digital you are deal with the analog parasitic components all of the time unless you have tooling that will take care of that for you.
You could build a 2 MHz computer on a breadboard and expect it to work. The main analog parts in old computers were at the periphery, the sound DAC, the video drivers (the hardware part of that), TV modulator (usually a module to allow for easy NTSC/PAL/SECAM adaptations), joystick interface (ADC, or switches, depending on the model), cassette tape interface and so on.
