The H-8 computers came with the 8080 installed. The Early H-89's had an ORG 0 problem with CP/M but none of yours have that problem ... they have all be modified. The Z-90 series came with the soft sector card installed from the factory. All H-89's were sold in kit form. The H-88 is another story. These were early all in one computers and did have 8080 CPU's in the beginning. Most H-88 units were upgrades to the H-19 terminals. How are you coming with your treasure trove of old H/Z stuff? I did find some more software and a few other spare parts. They are here whenever you holler. Mike Stover, KB9VU CCA# 404 CRA# 77 MARS AFA3BO Florissant, MO
