Texas Instruments TI-99/4A computer from 1981

CPU: 16-bit TMS9900 @ 3.0MHz
RAM: 48KB (16KB + 32KB expansion RAM)
Floppy Drives: 1 full height SSSD
Ports: RGB video, 2 joystick ports, cartridge slot, expansion slot
OS: ROM BASIC
Serial Number: 40004668
Notes: This system, the expansion box and a box of manuals were donated by John McDermott. The expansion box contains the 32KB RAM upgrade, an RS-232 card, the disk interface and the floppy drive. I had to make a video cable for it, and found power adapters for sale at Hosfelt Electronics.
