I am interested in buying (or borrowing) an H8 at some point if the price is right to explore the model and its workings. I remember talking to Alex Bodnar about them, and I told him then I had always "avoided" this model but it must be a past life or something that has always caused me to avoid getting involved with the H8's. Are they reliable?
Sometimes yes, sometimes no. Any that were built from kits will have been at the mercy of the soldering skills of the builder. I've seen some very good soldering on the insides of Heathkits, but also some abysmal soldering...it's a crap shoot. The other issue with H8s is the backplane connectors. Earlier ones used cheaper pins which were not gold-plated. These are enough of a problem that many people end up desoldering them (which is quite a job, especially without proper tools) and replacing them with gold-plated connectors. Other than that, the machines have a lot of personality and are a lot of fun to run. The front panel user interface is very good. They can run HDOS or (if properly equipped) CP/M. HDOS is a highly advanced OS for its day. Overall I'd say these machines are worthwhile. You'll find that they tend to fetch quite a bit of money on the used market, though. I recently restored both my personal H8 and one at LSSM, both with H17 floppy subsystems. I very much enjoyed doing that work, and the resultant running systems are great too. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
