First of all, I want to excuse my german english and I hope everyone can understand my writing.....

I worked now for 35 years in computers and collected a lot of stuff in my basement within this time.

So, if you find something interesting in here, let me know.....

- TM990 card cage
- TM990/100 processor board (1975)
- TM990 memory board
- TM990 floppy controller board
- Shugart 8'' SA800 drive
- Complete TMS9900 documentation
- Power Basic for TMS9900
- PDOS Operating System for TMS9900
- PDOS Basic

The 990 software and related documentation is all interesting. As far as I know, none of this has been archived yet.

Didn't I send images of the box of 990 floppies to you Al? If not, I can certainly do so.

Related question: what is needed to interface a SA800 to a "modern" machine? (a computer running Linux or FreeBSD)? Does the drive require mains voltage for the motor, or is it just 24 VDC? Does it need a separate controller / formatter board?

Mains voltage is required for the motor. Note that the motor and its pulley must match the mains AC frequency--i.e., you can't run a 50Hz motor on a 60Hz line, even if you get the voltage right.

+24, +5 and, some drives, also -5.
