FG5010
The Tektronix FG5010 is a 20 MHz function generator plug-in for the TM5000 system. According to Bob Beville's memoirs,
[In 1977 I was] in the FG5010 Function Generator design group. Dennis Hall, manager; Steve Rice, software, ramp/saw tooth/sinewave circuits; Tom Hill, output circuits; me, N Burst circuits, configuration and interface/motherboard.
All submitted their circuit’s inputs and outputs to me and what-connected-to-what. I arranged the motherboard connector assignments and some motherboard layout paths. The product became very crammed.

Internals
The original version (1982) had three Mostek MK36000 8K×8 mask ROMs (U1540 $A000-$BFFF, U1440 $C000-$DFFF, U1332 $E000-$FFFF). Code updates could be accommodated via a 2716 "patch" EPROM (U1640, 160-1712-xx) and a Signetics 82S107 "Field Programmable ROM Patch (16X48X8)" (U1420).
The updated CPU board (Rev.01, ca. 1985) replaced this complex arrangement with a single EPROM (160-1091-xx, 160-4971-00).
