Update to my proevious post. I used a 4052, which I did not realize was way different than the 4051 that uses a Motorola 6800 chip. The 4052 uses AMD chips ?????? See this text(link:
https://en.wikipedia.org/wiki/Tektronix_4050):
The second model was the 4052, which in spite of the similar name was a very different system. This had a CPU based on four
AMD 2901 4-bit
bit-slice processors used together to make a single 16-bit processor. It could also be used in a 6800-compatible mode, allowing it to run software from the 4051, although it did so much faster than the original 4051. Released in 1978, it came with a full 32 kB of RAM for $9,795, and could be expanded to 64 kB for another $1,995. The 4054 was a version of the 4052 built around the 19" screen from the 4014 terminal rather than the 11" screen from the 4012, increasing resolution to 4,096 by 3,072.
External storage units were available for the 405x series computers. The 4924 was an external version of the internal DC300 tape drive. The 4907 used single or dual
Shugart 851R 8 inch
floppy drives with 64 kB floppies and the larger, 2-drawer filing cabinet sized, 4909 storage unit used a CDC 96 megabyte hard drive with the first 16 megabytes in the form of a removable disc-pack. Two sizes of the 4956 graphics tablet offered a slow process for inputing from paper drawings. The 4952
joystick was used for graphics input.
Because the direct view storage tubes do not flicker as do conventional CRTs, and because the
BASIC programming interface allowed simple, rapid rendering of
vector graphic displays, the 405x series were used in many theatrical contexts. In particular, 405x computers can frequently be seen in early
Battlestar Galactica sets.
