Hey Tom, it's your lucky day, sort of.

CS-452 and CS-453 Injector drivers
In the Cherry Semiconductor Automotive IC Data Book (1992), they list
an "injector solenoid driver."  The part number is CS-452 (2.4A peak
current), and the CS-453 (4.4 A peak current).  These parts appear to
be equivalents to the Motorola MC3484S2-2 and MC3484S4-2,
respectively.  The pinout and package are the same.  Comparison of the
specs shows identical performance. 
 I have no idea what these cost, or if they are still available.

Should be able to find it at www.national.com
they are the same, except 2917 has a zener between

DESCRIPTION
The MJE3055T is a silicon epitaxial-base NPN
transistor in Jedec TO-220 package. It is
intended for power switching circuits and
general-purpose amplifiers. The complementary
PNP type is MJE2955T.

RC4200 (raytheon)

Analog Multiplier

Features

     High accuracy 
     Nonlinearity - 0.1% 
     Temperature coefficient - 0.005%/ C 
     Multiple functions 
     Multiply, divide, square, square root, RMS-to-DC conversion, AGC
     and modulate/demodulate Wide bandwidth - 4 MHz Signal-to-noise
     ratio - 94 dB 

Description

The RC4200 analog multiplier has complete compensation for
nonlinearity, the primary source of error and distortion. This
multiplier also has three onboard operational amplifiers designed
specifically for use in multiplier logging circuits. These amplifiers
are frequency compensated for optimum AC response in a logging
circuit, the heart of a multiplier, and can therefore provide superior
AC response.

The RC4200 can be used in a wide variety of applications without
sacrificing accuracy. Four-quadrant multiplication, two-quadrant
division, square rooting, squaring and RMS conversion can all be
easily implemented with predictable accuracy. The nonlinearity
compensation is not just trimmed at a single temperature, it is
designed to provide compensation over the full temperature range. This
nonlinearity compensation combined with the low gain and offset drift
inherent in a well-designed monolithic chip provides a very high
accuracy and a low temperature coefficient.

The RC4200 is ideal for use in low distortion audio modulation
circuits, voltage-controlled active filters, and precision
oscillators.
