This web site is the home of the SEBHC. The SEBHC archive contains a
full set of documentation and software for use with the Heathkit H-8 and
H-89 computers. All of the documentation is in the
PDF
format and all of the software, in the form of disk images, are in the
H8D format.
FOR THE LATEST DOCUMENTATION AND SOFTWARE PLEASE REFER TO THE WIKI PAGE WHICH IS UPDATED AS NEW ITEMS ARE ADDED

Heathkit H-8 PCBs
A complete set of replacement boards for the H-8 computer can be
found here. These are all new designs based on the original Heathkit
schematics with the exception of the H8-Z80-64 CPU board which is an
original design.
Using the PCBs available from the above link it is possible to construct
a complete working Heathkit H-8 clone computer. I call the clone the
H8-2000 but it has also been dubbed the L-8 (for Les-8) by other members
of the group. For detailed instructions on how to build a complete
working H-8 clone click the link below:

The GIDE is an IDE hard disk interface for Z80 based computers. To get
the GIDE to work with Heathkit computers click the link below. At this
time the GIDE will only work under the CP/M operating system.
The SVD is an electronic floppy disk with 256K of onboard RAM. The HSFE
is a device that simulates hard sector pulses so you can use 3.5" floppy
drives with the H17 hard sector controller card.
