Dear members and friends of CUUG,
What have people been doing lately with the Raspberry Pi other low cost
machines?
Some issues people describe kick me back 40 years to problems we solved in the
mid-1970s
when PDP-8s were the micro kings and priced near the cost of a pretty
respectable car.
Wasn't this the target machine for Brian Kernighan and Dennis Ritchie when
first designing C?
i++; and i--; translated directly to to incm <addr> and decm <addr> machine
instructions.
PDP-8/E Specifications Word size 12 bits
Maximum memory 32k words (8 4k banks)
Minimum instruction time 1.2 microseconds
Add memory to accumulator 2.6 microseconds
12 x 12 multiply with 24 bit result 256.5 microseconds (subroutine)
12 x 12 multiply with 24 bit result 40 microseconds (with EAE option)
Operating Environment 0 to 55 C (32-130F) 10% to 90% Humidity
Power <= 450 watts (varies with option cards)
Size (HeightxWidthxDepth) 10.5x19x24 inches
Weight 100 lbs total, 45 lbs power supply
Cost Minimum Configuration 4k memory $4490 installation included from DEC in
1974
$53 per month for maintenance
Cost in configuration shown, excluding I/O devices
and third party boards $14835 from DEC in 1974
$134 per month for maintenance
Come and join us for an interactive evening.
