Mostek published a great little Z80 reference card called the “Z80 Microcomputer System Micro-Reference Manual”. In addition to the Z80 CPU, it covers the PIO, CTC, and SIO, but not the Z80 DMA. Unfortunately it’s long out of print, so I decided to try to recreate it in LaTeX. I’m a LaTeX novice at best, so this is quite a challenge. Here’s a PDF sample of pages 1, 2, 8, and 9. There’s a scan of the original on Bitsavers.
Page 1 (“Flag Summary”) is nearly ready, other than the positioning of the page number, but there’s a lot of work yet to be done to get the formatting right on the other pages. I mostly want to reproduce the original fairly closely, but on page 2 (“8-Bit Load Group”) I moved the Implied Source operand columns (I and R registers) to the right side of the table, because I always thought it looked wrong with them on the left.
I can’t figure out why on page one the horizontal line separating the headings from the body of the table stretches off to the right edge of the page.
This will require meticulous proofreading.
