PDP-8/E front panel
|Design Type:||clocked random logic|
|Memory Speed:||1.2 μseconds|
|Physical Address Size:||32KW (requires optional KM8-E)|
|Virtual Address Size:||4KW|
|Memory Management:||bank selection, CPU mode|
|Operating System:||OS/8, TSS/8|
- KA8-E Positive I/O Bus Interface, to allow use of older PDP-8 devices
- KM8-E Memory Extension and Time-Share Option, which was needed to support more than 4K words of memory, and allowed the computer to operate in either Executive Mode or User Mode
- MP8-E Memory Parity
- KE8-E Extended Arithmetic Element, which supported hardware integer multiplication and division, one-bit double-word shifts, and normalization
It could perform an addition to the accumulator in 2.6 μseconds, and a 12 by 12 bit multiplication with 24 bit result in 40 μseconds, using the math extension hardware.
The -8/M could be supplied with either a KC8-M Operator's Console, or a KC8-ML Programmer's Console, the latter being basically identical to the KC8-EA Programmer's Console of the basic -8/E.
