Hi,
I hope that this might be of some interest to some of you on this list.
I just finished bringing up a complete operating reproduction of a SCELBI 8B with TTY and Cassette interfaces. I have previously completed a SCELBI 8H reproduction. Between the two projects, it has taken 3 and 1/2 years, required reproducing 13 different printed circuit boards. Each reproduction system contains over 900 components, including over 100 memory ICs.
The SCELBI 8H was the first microcomputer known to be marketed to hobbyists. The first ad for the SCELBI 8H was published in QST magazine in March, 1974. The SCELBI 8B was released about a year later and included more memory capability (16K) and a built in monitor, assembler and editor, essentially a complete integrated development environment. There are only a few surviving SCELBI 8B’s and as far as I know, none of them are in fully functional condition.
More information on the SCELBI and my reproduction efforts can be found by following these links.
