Noel,
Some more info on my machines...
*The
DLV11-J: http://gunkies.org/wiki/DLV11-J_asynchronous_serial_line_interface
<http://gunkies.org/wiki/DLV11-J_asynchronous_serial_line_interface>is
basically 4 DLV11's rolled into a single dual-width card; that's
definitelyan option for Mini-Unix (which apparently supports up to 4
simultaneoususers). They are program compatible with the DHV11, so the
driver should 'justwork'. The boards are readily available on eBait;
'glitchworks' (of thisparish) sells replacement cables (quite good, I have
several).*
I bought a DLV-11J on eBay so that's a starter for my /03 machine. I've
also bought an MSV11-DE 32kW memory board. Peter Schranz has confirmed a
modification to his RLV12/RL02 emulator to allow it to run on the /03. I'm
all set for Mini-Unix on the /03 then!
Regarding the KDF11-B:
*If yours doesn't have the MMU chip, you're probably SOL; those are very
rare.KEF11-A FPU chips are avilable on eBay for modest amounts. *
Looks like I'm in luck! My /23+ CPU board does have the MMU installed. I
also bought a KEF11-A separately. Glad my wife doesn't know about all these
purchases. ;)
