+# PC-E220-Tools
+
+> Version: 1.0.23042.1 \

+## About
+The PC-E220 was one of the last, and by far the most powerful of the Sharp Pocket-Computer series.
+
+These where small computers, you could actually carry around with you, and use on the go. While
+most of them where glorified programmable pocket calculators, the PC-E220 came with 32KiB of RAM and
+a CMOS-SC7852 CPU, that was code compatible with the Zilog Z80A at 3.58 MHz. That made the CPU
+faster than an Amstrad CPC or other Z80 based machines of the time.
+
+While the 144x32 dot-matrix display is not very well equipped for graphics, because it is divided
+into 5x7 cells, it can print a wide range of characters, and displays 24 characters in 4 rows.
+By the standards of a pocket computer, that was a lot.
+
+In order to write and use machine codes, it would be handy, to have a handful of tools, that
+allow interacting with a computer in a more user friendly way.
+
+Some of the tools I'd like to have:
+
+- Save and load machine language programs to tape without the need to assemble them first.
+  A small BASIC program should be able to simply create an image of a given memory block
+  should be able to achieve this.
+- While the PC-E220 has a built-in assembler, it lacks a built-in disassembler. The monitor program
+  it has built in, is -depite it's name- nothing more than a memory monitor. It does a well enough
+  job, but I'd like to have something more in the line of the Commodore C-128 monitor.
+  This should be written in assembly itself, and no larger than 8K (which would already be huge for
+  such a program.)
