    hey’re Here! The New Heathkit Personal Computing System!…

    Direct to you from 1977: “NEW H8 8-Bit Digital Computer. This 8-bit computer based on the famous 8080A microprocessor features a Heathkit exclusive “intelligent” front panel with octal data entry and control, 9-digit readout, a built-in bootstrap fo…

    Fast systems are a relative term…

    You think your system lacks oomph, check out this classic ad for the ultimate 8 bit system from 1975: NEW H8 8-Bit Digital Computer. This 8-bit computer based on the famous 8080A microprocessor features a Heathkit exclusive “intelligent” front panel……

  4. […] And finally, the New Heath Kit Personal Computers is an excellent piece on what probably represents the first true, fully functional PC to be sold. Even in today’s $$, the process listed aren’t cheap, and given that the ad is from 1977, they are pretty pricey pieces of kit. Having said that, the H11 16-bit system was truly revolutionary for the day, essentially a full “mini-computer” on the desktop. This is pointed out near the end of the write up in geek-speak … “DEC PDP-11 software is included.” PDP-11 was still in business use a decade later on mini-computers in a variety of industry and educational settings, and at the time represented a VERY powerful operating system. And on top pf all that, you have a choice of paper tape or the ultra high-tech cassette tape deck (still in development, you’ll note, lol) for data storage. Its also worth noting that the internal storage set of this high-end system was 20Kb … far less than the 5MB hard disk I wrote about earlier. As late as this ad in 1977, a 5MB hard disk was still a pretty cool, and pretty high-end, piece of kit. […]

    I built one of these in 77-78. I soldered the tantalum capacitors in backwards and when I powered it up the sweet sound of popping corn could be heard on the power board. Fortunately RCA had a depot down the street where you could pick up tubes, etc. AND new-fangled electronics.
    After a rebuild I was able to play hangman and attach a audio tape drive for backup.

    My buddy and I built the H11 kit in high school in 1978. It was a ‘real’ computer, and it replaced the punch card box in the schools office. We got a write up in the local paper when it went ‘on-line’. I look back at it as a neat toy, and we were lucky to have it. They also got us the H9 terminal, and I remember having to put it together. It got to be so important to the principle; we got passes out of other classes. We got all the time we needed to solder the hundreds of components into the PC boards
