I use that chip in an old project with an 8051 microcontroller. They are
becoming obsolete, I had to switch to the PSD913F if I recall correctly (or
maybe the other way around?)
I have a couple of the programmers too. They work from the printer port, you
are talking about certifiable dinosaurs
Most EEPROMs have I2C or SPI interfaces. Some Flash chips have JTAG.

It's a chip (PSD813F) which has 1MBit flash, 16Kbit SRAM and 256Kbit
EEPROM. It's old school with parallel data/address bus and all that :) It
does have JTAG.

I recently came across a thread on this list about undocumented FE5680
commands. I have been using a little linux command line tool I wrote years
ago for tuning the unit and decided to add these commands to it.
Since this mailing list was the place I found the unit (someone linked to
an ebay
I don't know how crowded the board is, but I would use an SMD DIP clip
instead of unsoldering the chip.

I don't have the clip-ons but of course I could get them. I know the chip
has a JTAG interface, but I've only used JTAG with chips that came with a
programmer and software :) (except with OpenOCD over parport once, but that
was in the stone age).
Another question about the EEPROM
I haven't looked at the EEPROM dump, so I can't help you with that. Perhaps
someone else can.
One place for various adapters to program chips is MCU Mall. I have
purchased from them a few times.
