Bet you didn't know...(PDP-11)

Jerome Fine replies: Any idea how much these boards cost and what the speed ratio is vs the PDP-11/93? I had heard that QED was getting speeds of 6 times the PDP-11/93, but that was many years ago. Of course, a Pentium 4 running E11 can now achieve between 50 to 100 times a PDP-11/93. Plus each emulated disk drive can be many GigiBytes with I/O speeds also of 50 to 100 times any "real" DEC drives. Currently I am still using a 750 MHz Pentium 3 with 80 GigiByte ATA 100 hard disk drives. Under W98 SE and FAT32, a 2 GigiByte file can be used under RT-11 (or RSX-11). I can read/write all 32 MegaBytes of an RT-11 partition in a few seconds. Since the system has 768 MegBytes of RAM, the system caches the emulated drive and after the first access, reads/writes are from memory. So I can understand why Mentec now sells only emulators. In addition, E11 even supports a BCI adapter for commercial users which allows a real DEC Qbus to be used when non-standard hardware is still needed.
