Book on computer architecture for beginners 728

I have some vague recollection of special train that printed sideways .. so top of page was at the side ... and multiple pages taped together ... not across the perferations ... but across the sides (after the tractor holes were removed). Also, the 1403 would be switched from the normal 6 lines per inch to 8 lines per inch.

you can pretty clearly see the 1403 printing in this vm370 manual

the first couple pages, prefaces, etc have been typeset ... then the contents (on the 6th page) changes to 1403 font ... and the first box diagram on page 9 of the introduction (11th page) has broken vertical lines (as an aside ... the two 370 PoPs at the above site are typeset and not 1403).

note also ... that the original script formating controls were runoff-like "dot commnads" (before GML support was added). frequently used were

.rc on .rc off

and-or

.rc 1 on .rc 1 off

which indicated revisions. revision codes are indicated by the side-bar next the text. you can see this (also) on page 9 of the introduction (11th page) on the top left ... in the paragraph that starts "VM-370 is designed for ...". again the vertical bars on broken

The revision is for virgil-tully ... 370s 138-148. The following page (12th page) shows a diagram about a 138 configuration (again note the revision bars on the side).

On the following page (13th page), there is an inserted drawing that has continuous lines ... and also a different font. But if move on to the next page (14th page, pg. 12 of the introduction), you have more diagrams with broken vertical lines and also broken line revision bars mentioning VMCF.
