*PROBLEM*
How to quickly download S-records from a MicroVAX to an embedded 68020
VME system.

*BACKGROUND*
We're developing code for an embedded 68020 VME system. 

Our development environment is VMS in a network of VAXen and
VAXstations.

We currently use the Green Hills C compiler, and may move to the
Microtec compiler in the future.  

We plan to use pSOS+ with pHILE+, pROBE+ and X-RAY as system software.

Anyway we ultimately generate S-records and download them via RS-232
lines into the target machine. Even at 9.6K baud, this is SLOW!

The new lab we are building will have its own MicroVAX and will have
access to the DecNET thinwire ethernet cable.  The MicroVAX will be
"close" (<10 feet) to the target hardware.

*SO*
Can any of you kind souls point me to a faster way to download code
into the target for testing and debugging?

Maybe a parallel interface from a Q-bus card to a VME card with
appropriate (soft/firm)ware?  Maybe a single-card VME Ethernet
interface with on-board software that understands DecNET?

We really want to buy a solution rather than rolling our own.
