## 1126kB 8" DSSD

The Texas Instruments DS990 was a multiuser modular computing system from 1998,
|
||||
based around the TMS-9900 processor (as used by the TI-99). It had an 8" floppy
|
||||
drive module, the FD1000, which was a 77-track, 288-byte sector FM/MFM system
|
||||
with 26 sectors per track. The encoding scheme was very similar to a simplified
|
||||
version of the IBM scheme, but of course not compatible. A double-sided disk
|
||||
would store a very satisfactory 1126kB of data; here's one at <a
|
||||
