Z-80 assembly was such _fun_ to >hack in! I got started programming on a 4K TRS-80 Model I. I remember fondly the upgrade to 16K. (Some outrageous price, like $200. Maybe more.) I remember equally fondly learning Z-80 assembly language using T-BUG. Imagine my delight when I encountered a fellow hacker (now the most senior staff member on the Transarc transaction system project in Pittsburgh) who had a DISK system with 48K AND this thing called a "macro assembler" ... those were the days. Then imagine the delight we BOTH felt upon encountering the Model III in the computer lab. Since then I've written a few thousand lines of Z-80 assembler, and a lesser, but considerable amount of 808x, VAX, 6502 and 680x0 assembly language; the doggone backwards ordering of the Z-80 operands still gets me sometimes. A friend of mine built a Z-80-based system (which originally ran cassette basic) in 1977 (or thereabouts). Hand-tweaked each buss termination in order to run the Z-80 at nearly 4MHz (remember, the first were originally rated at around 2MHz). Damn thing still works; I have no idea what the FCC would think of it, though ... Oh, well ... back to MacW[h]arehouse and the White Knight controversy ... :-) v v sssss|| joseph hall || 4116 Brewster Drive v v s s || jnh@ecemwl.ncsu.edu (Internet) || Raleigh, NC 27606 v sss || SP Software/CAD Tool Developer, Mac Hacker and Keyboardist -----------|| Disclaimer: NCSU may not share my views, but is welcome to.
