The hardware features of the QDP-300 were very close to those of the QDP-100 model. Apart from the shape of the case, the major differences were:
- An integrated help system,
- A cache memory to speed up the disk drives operations,
- A new motherboard design allowing the 6 Mhz. Z80-C microprocessor to be used.
The QDP-300 was backed by one-year on-site warranty performed by the General Electric Company.
Mark Penacho adds:
The Quasar Data Products QDP-300 was rebranded the TDS-300 (by QDP) and was used as the development system for the now defunct handheld computer company Telxon in the early 80's for their handheld devices.
The rebranding was a darker metal case (I think dark blue), and a blue front panel. Cosmetically, the TDS version looked nicer.
Roger Chalonec remembers:
I used these on US Navy ships. We ultimately had a 10meg hard drive in these I belive. We ran a pretty impressive database called MDBS (Micro Database Systems) out of Cleveland, OH.
We need more info about this computer ! If you designed, used, or have more info about this system,
please send us pictures or anything you might find useful.
