I remember quit well reading, around 1977, a booklet from around 1973, I believe by
Kluwer, describing a DIY computer build around the Siemens/Philips FDxnnn series of TTL
chips.
Memory was a philips corestack-module, something like 1K or 2K x 12 or x16.
Of course there was no way of me building that in 1977, but now....
Does this ring a bell with anyone ?
