The 1219 uses the same 15 pin cards as the CP-642 NTDS computer. These same cards used in the 1532 I/O console (OA-9784 or Mk. 77 Input-Output console) Which I scanned and uploaded to Bitsaver : http://bitsavers.informatik.uni-stuttgart.de/pdf//univac/military/1532/ My scan of the student study guide for the 1219 Not 1219B is Here : http://bitsavers.informatik.uni-stuttgart.de/pdf//univac/military/1219/ I think that the only difference is in the memory section. The 1219B memory has 10 pin UNIVAC custom DTL nand flatpack chips on 56 pin circuit cards. I always thought of it as a 2.5 generation computer. The original Manuals are at VCF More info on Univac 18 bit hardware Here: http://vipclubmn.org/cp18bit.html Link to my Univac Computer Yahoo! Group : https://groups.yahoo.com/neo/groups/UnivacComputers/info I have posted my 1219/1532 emulator, assembler and instructions to the group.

Wikipedia is correct. Ours is a transitor Univac from the Sperry-Rand era.
