List-Id: Computer Old Farts Forum Archived-At: List-Archive: List-Help: List-Owner: List-Post: List-Subscribe: List-Unsubscribe: From: segaloco via COFF Reply-To: segaloco Hello, today I have received an IBM binder from 1974 pertaining to IBM Skyl= ab activities as well as a small IBM SLT, single wide, with four modules on= it. Two of the modules are labeled: 361456 IBM WF 1 03S 215 And the other two are: 361453 IBM 22 1-009 415 >From what I could find online, there is a close SLT card with 4 of the 3614= 53's instead of 2, but that doesn't help much. That board is listed as 002= 11 in the reference this info is from[1]. Faintly on the connector I can m= ake out: 00008 A 0 204 YM It is very, very faint in places though so that may not be correct. The sp= ecific little blocks on the board appear to show up on others, so nothing u= nheard of, although I wouldn't know where to start on identifying what this= does precisely, all I can find are cursory references in a few places to t= he numbers on the chips re: SLT modules. - Matt G. [1] - https://ibm-slt-reference.fandom.com/wiki/SLT_Board_List (why is this= a fandom.com wiki...) P.S. If you or a loved one are in possession of IBM mainframe hardware that= would benefit from this SLT board, happy to send it to you, I probably won= 't do much with it unless I can figure out the pinout and do weird things o= ver GPIO pins from one of my single boards.
