M8186 CPU

The KDF11-A CPU is dual-width PDP-11 CPU card for the QBUS; it uses the same 'Fonz' F-11 chip set as the other KDF11 CPUs.

It contains only the basic CPU, unlike the other KDF-11's: no ROM, no serial lines, etc.

The first version of the KDF11-A (Revision A) only suppported 256 Kbytes of main memory; later versions supported up to 4 Mbytes.
