Continuing my post-op clear out , I have a few of these 'kits' that might interest people here.
The 'kit' consists of:
An FG202SA2 Itron dual 101 segment bar graph VFD glass unit (2 x 100 individually addressable segments plus 1 double segment ). Blue/ green in colour.
Two off: SED2020 serial input to 20 output segment driver chips (30-70v 10mA)
A 3-5v input to 40v (?) plus filament drive module.
I have a zip file with basic circuit and a PCB design (gerbers) for a display module (see photo) . Unfortunately, I have no PCBs to make up the modules.
The VFD is not difficult to drive: One full Frame consists of 19 five byte (40bit) fields that are synchronously clocked to the pair of SED2020s . The field bits select grid or grids and individual segments. The frame rate can be sufficiently fast to allow for on duration brightness control.
There is PIC P16F887 assembler code to drive them , gerbers and data sheets in the zip file here:

I've seen similar vfd glass only sell for over £50 so ,
£50 + postage (£5 UK, £12 international)
