As posted previously I am trying to repair my VT100 and I am having trouble with the Monitor Board. The one I have does not match the available printset (PDF p54 of this https://bitsavers.org/pdf/dec/terminal/vt100/MP00633_VT100_Schematic_Feb82.p df). My VT100 appears to match the older https://bitsavers.org/pdf/dec/terminal/vt100/MP00633_VT100_Mar80.pdf printset, but it doesn't cover the monitor board. My monitor board looks as follows https://rjarratt.wordpress.com/wp-content/uploads/2023/12/img_20231221_11223 3.jpg and the two big transistors on the left appear to be incorrect parts possibly from a previous repair attempt before I got the VT100. Does anyone have a previous revision of the VT100 with a Monitor Board that matches mine? If so, would you be able to photograph it please, or tell me what parts are installed for the two TO-3 transistors on the left? Better still would be if anyone has the printset for this version of the monitor board. Thanks Rob
