Need help with dead 11/23+, FIXED :) - test-drb@ccmp.vtda.org

  The later the version, the more MSCP boot devices are

 supported, and you're supposed to upgrade the ROMs in a KDF11 to match 
 those in the RQDX1 or RQDX2 controller *and* vice-versa, and you should 
 definitely use -BF or later for RQDX3.? Version -BG (called -BH in some 
 places, it's the same ROM set and same code) introduced TK50 boot 
 support, and -BJ refined that to make it more reliable. 
That would make sense, then.

I had the -BF proms, when my 11/23+ had an RQDX3 and some RD52's.
(This was back around 1990-ish)
At that time, I was using?a Cipher F880?under?TSV05 emulation,
so I wouldn't have noticed the lack of MU boot support. . .?? 

The TK50 was on my "new" 11/73.
Darned if I can remember what I was running for disk back then.
Fujitsu Eagle, with an SC03, maybe???? ;-)
