I been teaching photography for many years and yes, back then if you had a darkroom you could print from both negatives and slide film (positive images). If you printed your own color film, you could do dodging, burning or change contrast. I am not sure if Ilford or other company's still have the chemistry available, chances are that they do not. But B&W printing is still possible and there is an absolute pleasure for me to teach that at Truman College in Chicago.
Perhaps the best alternative to Cibachrome/Ilfochrome and Kodak Ektaflex (all defunct) is to digitize slides and transparencies on a digital camera or high-end scanner, then adjust them in Lightroom Classic/Photoshop and print them directly through a 16-bit driver to a high end Canon or Epson pigment inkjet printer. The finest portrait, commercial, and art photographers, the best art schools, the top high-end service bureaus, and the top art museums selling prints of exhibited works for artists all use this method.
My biggest annoyance with printing directly from transparencies was always contrast control. Transparency films can record 4-5 times the contrast range that paper can reflect. Good as they were, the reversal printing methods of the '70s were just too contrasty to capture the brilliance of Kodachrome without blown highlights and plugged shadows. Macro photographing slides in 12-14 bit raw, or scanning to 16-bit files, can retain highlight and shadow details that can be compressed in post-production software to fit within the dynamic range achievable with a particular printer/paper/ink combination. The results are much more natural, with considerably more detail visible. With digital, we can control every aspect of the image precisely.
I worked with Kodak Internegative film extensively in the late '80s to mid-'90s. We made hundreds of thousands of elementary school class composites with that film at the lab I worked for. It controlled contrast well... sometimes TOO well. But it was very hard to maintain a stable color balance. The film itself was unstable, drifting in speed and color balance over a short period (a few months). It was very sensitive to C-41 process drift. It required LONG exposures through thick filter packs. The switch to digital saved us a ton of money, improved the quality, and drastically cut turnaround times. It also enabled major product design improvements.
In fact, one of modern digital photography's key post processing advantages over film, generally, is its predictable control over color temperature, hue, contrast, sharpness, saturation, dynamic range, and all the other factors that contribute to image quality. There may have been a, "Wow it gives me the hebejebes watching that image come up in the developer" factor to (B&W) analog photography, but that pales when you consider the control digital tools offer. Now it's, "Wow, look at all these sliders and how easy it is to get the look I want!"
