The defunct CEGMON story

The original monitor-chip MONUK01 (yesterdays "BIOS" to some extent) was standard in the beginning and included in the kit that I assembled.
Soon I replaced it with the "New Monitor" that had some extra features, but also a lot of changes such as vectors and.... the flashing prompt that blurred the screen! Yes, I know it could be switched off by a POKE.

Later, when then I did the extended video mod, a new monitor was needed to support 32 lines.
I bought the CEGMON monitor (extended), a full featured monitor with a lot of good functionality, good documentation and...support for 32 lines! I liked it a lot!
Unforturnately I zapped CEGMON EPROM in -84 when I did a printout of the EPROM content and swapped it with power ON! No supplier/agents were still in business in that time and I had no means of reprogramming a EPROM myself. This was the end!!...or..??
The disassembled printout would later prove to be very important!
The CEGMON issue was resolved in Oct. 2008 by some help from the community.

From the printed listing I painstakingly started to type every byte into a freeware hexeditor (Neo), then sanity-checked the code in a freeware 6502 assembler (6502sim). Good tools by the way...
A helpful friend, found in a electronic forum after crying for HELP!, then programmed a 2716 EPROM for free. The 2716 and even the postage were w/o cost. Great! Thanks!
As you can see from the below picture, the UK101 booted up nicely with the new reborn CEGMON monitor.

Yes, it works! In full 32x48 !
