I'm selling some of the prototype boards for my GW-OSI-RAM1 Universal 128
KW RAM board. This board provides up to 128 KW (64 KW without memory
management) of static RAM on the Ohio Scientific bus. It supports a 12-bit
word size and is compatible with the Ohio Scientific 560Z "Processor Lab"
in PDP-8 mode. It also includes a prototyping area, and a header for
mezzanine display boards. Included with the auction is a Hex Lamp Register
and an Octal Lamp Register, which can be mounted directly to the
GW-OSI-RAM1 or used remote on a cable (e.g. for a front panel).

This is a pre-production board, the most significant difference is that it
lacks a corner mounting hole, which can be drilled if needed (no circuit
traces run under its location). The other differences are minor. See
auction link for full description!

Thanks,
Jonathan
