xNote: TEI also manufactured several S100 chassis similar in design to Imsais like an Imsai with no front panel and the right side had no vents:<BR>
22 slot.<BR>
12 slot mini-chassis.<BR>
12 slot full size chassis with MB in rear & cutouts up front for three 5.25" drives.<BR>
<BR>
Disk drive cabinets:<BR>
Mini chassis with no MB but cutout for three 5.25" disk drives (often stacked with 12 slot chassis).<BR>
Dual 8" cabinet.<BR>

All TEI power-supplies used ferro-resonant power-supplies (Constant-Voltage-Transformers) which ran most S100 cards cooler than other chassis. The CVT's also ran better with poor quality line voltage.<BR><BR>
Most TEI's were sold as empty chassis that people populated with other (better) cards. TEI started out as a power-supply manufacturer for mini-computers then decided to jump on the S100 train. The made 8080 based systems when everyone else was building Z80's. They made great chassis's but poor cards.<BR><BR>
TEI chassis are fairly common but the entire TEI computer is very rare.<BR>
