Hi Aimee,
We actually have done the PC upgrades that Matt references that replace DEC
PDP-11s running RSX-11 with PCs. We haven't actually done the equivalent for
Alpha machines running OpenVMS but a few of the simple things to try first might
be :
- replace SCSI drives, assuming SCSI is being used, with some sort of
SCSI-to-SATA or SCSI-to-SD adapter and new drive hardware (Google will find
these pretty quickly although you will have to pay attention the the SCSI
connectors and the generation of SCSI interface being used)
- replace the actual DEC Alpha processor hardware with an emulation such as
EmuVM and AlphaVM-Pro which uses emulated disks and tape drives. I have never
tried it so I can't make a recommendation one way or the other but it would
likely be a good place to start
The actual connection to the E-beam hardware might be tricky. We have done
upgrades for XLS steppers that replace the Sparcstation and SunOS with an
emulation but the hardware interface in that case is a fairly basic ethernet
network connection. If it's a custom hardware interface you may have to stick
with the existing Alpha computer hardware.
If you can actually run an emulation, the network backup file that you mention
might serve as a suitable disk image. We should be able to read your SCSI drive
(assuming that's what is being used) and generate a binary file image for use in
an emulation if your network backup is unsuitable. If you wanted to pursue this
further, or have further questions, then please let me know.
Best regards
