MCP23008/MCP23S08 8-Bit I/O Expander with Serial Interface
High-speed SPI interface (MCP23S08) - 10 MHz

The SPI bus specifies four logic signals:

SCLK: Serial Clock (output from master)
MOSI: Master Output Slave Input, or Master Out Slave In (data output from master)
MISO: Master Input Slave Output, or Master In Slave Out (data output from slave)
SS: Slave Select (often active low, output from master)

CP/M is logically divided into several distinct parts:

BIOS (Basic I/O System), hardware-dependent
BDOS (Basic Disk Operating System)
CCP (Console Command Processor)
TPA (Transient Program Area)

SYSTEM FORMAT
9 sectors per track numbered #41 to #49.
2 reserved tracks.
The system format is the main format supported, since CP/M can only be loaded (cold
and warm boot) from a system format disc. The reserved tracks are used as follows:
Track 0 sector #41: boot sector.
Track 0 sector #42: configuration sector.
Track 0 sectors #43.. #47 unused.
Track 0 sectors #48.. #49 and track 1 sectors #41.. #49: CCP and BDOS.
Note: 'VENDOR' format is a special version of system format which does not contain
any software on the two reserved tracks. It is intended for use in software distribution.

The Atmel® AT27C256R is a low-power, high-performance, 262,144-bit, one-time programmable,
read-only memory (OTP EPROM) organized as 32K by 8 bits. It requires only
one 5V power supply in normal read mode operation. Any byte can be accessed in less than
45ns, eliminating the need for speed reducing WAIT states on high-performance microprocessor
systems.

27c256-120T, existuje ešte lepšie riešenie - použiť čip W27c256 od Winbond, jedná sa vlastne o EEPROM určený práve k náhrade EPROM

I have taken a look at the 27cxx (UV EPROM) chips datasheets and compared to the 28cxx (EEPROM) and 29cxx (flash) ones.

what is a replacement for 27C256 Eprom
28c256 it works but too slow when programming. 29f256 should work fine

27C256 =  3 EUR EPROM  -  70 ns
28C256 = 11 EUR EEPROM - 150 ns
29C256 =        FLASH  -  90 ns no DIP

Since Notepad++ Version 6 you can use this regex in the search and replace dialogue:

^(.*?)$\s+?^(?=.*^\1$)
and replace with nothing. This leaves from all duplicate rows the last occurrence in the file.

No sorting is needed for that and the duplicate rows can be anywhere in the file!

You need to check the options "Regular expression" and ". matches newline":
