====== Video Data Systems 840AE ======
 
The 840AE was an updated variant of the CG840, offering upgraded page memory and a PS/2 keyboard connector instead of AT. Because Keywest Technology continued selling the 840AE after purchasing Video Data Systems, it could sometimes be seen bearing Keywest Technology branding.
