STMicroelectronics ST62T40B; this is a microcontroller from around 1998 I believe
It's in a generator controller "DSE530" long obsolete and unsupported by it's maker Deep Sea Electronics.
The normal method of programming different user parameters into this box is by way of using their proprietary Windows XP software and their general purpose RS232 interface cable "DSE808".
The programming software is still freely available but the DSE808 lead seems impossible to find.
Out of all the chips in this DSE530, only one has memory functionality and that's the ST62T40B microcontroller.
I wondered if it might be possible to download this chip's 128-byte EEPROM memory and identify within it, fields that represent each user parameter. Modify as neccessary, then reload the chip. Assuming the ROM readout protection hasn't been instigated and / or doesn't extend to the EEPROM.
Apparently one requires an EPB to do this:
Not sure if these are even available anymore
Has anyone here dealt with one of these microcontrollers before? Is there an easier approach than trying to find a ST62E4XB-EPB/220 board?

EPROM PROGRAMMING BOARD FOR ST62T40B MCU
ST62E4XB-EPB/220
1998
with Windows 3.1x software
Objective:
- read ST62T40B Data EEPROM to disk file
- (128 bytes total - 2 pages 0 & 1 of 64 bytes from 00h to 03Fh)
- write Data EEPROM back from disk file 128 bytes total, to ST62T40B
Not sure if these are even available anymore
