basically a device that lets you share a single keyboard, mouse andamongst up-to-several computers) and a Mac-to-VGA adapter (for connecting
the SE30 internal video card output to the input of the KVM, and thence
onward to the PC monitor), would rather make the whole arrangement quite
within the realm of the decidely and practically useful, and without the
least diminution of the "all-in-one" concept.
Well, okay. I'm not sure what type of card you're talking about. The card I
offered on eBay is a Radius Full Page Display card for SE30. What kind of
adapter would connect that to a VGA display? I thought these cards were
designed for Radius monitors and Radius alone...no? I'm pretty sure the
output is a DB9 connector.
Specs for the Radius monitor range can be found in the Griffin monitor database. You'll find references to several versions of the Radius Full Page Display (FPD) and it's quite likely that both DB9 and DB15 connectors were used. In the late 1980's when Radius developed these products, few PCs used hi res analogue displays so the awful HD15 connector was not in popular use. Monitors like the NEC Multisync 1 and Sony Multiscan used DB9 connectors while Apple went along the DB15 route probably because Macs already used DB9 connectors for serial and mouse.
The Radius FPD card was designed to support the Radius FPD and the resolution and fixed frequency for those monitors are unusual. However they are very close to the res and freq used by some Sun workstation monitors so if you're prepared to make up your own cables you might get a working setup. It's even worth trying such cards, particularly ones with 1990's ROMs, with a generic multisync display. My Radius Pivot card works fine as a colour 640 * 480 display card.
When new, compact Macs with big displays were popular for creating drawings, artwork etc. When the job was ready, the owner could unhook the Mac and take it to their bureau to print it out from the Mac that had the appropriate software and fonts installed. The SE/30 is still useful for similar applications today.
