Earlier this week a nostalgic OmniWeb user emailed in looking for release notes from the early days of OmniWeb. Back when we were apparently trying to find the right pixel-width for IFRAME borders. This is all before my time at Omni, but luckily I can still go through our entire OmniWeb mailing list archives.
OmniWeb 1.0 was free to regular folk and $120, per seat, for organizations. It was exclusive to NEXTSTEP and OpenStep and kind of a great value: you could access the internet!
The printed documentation had some blood, sweat, and tears, too.
