Thank you! It is indeed the same UPS described by Mutlu in
(a google search on the firmware IN01064B turns up the thread)

with blazer_usb driver I get:

$ upsc myups
battery.voltage: 27.00
battery.voltage.nominal: 24.0
beeper.status: disabled
driver.name: blazer_usb
driver.parameter.pollinterval: 2
driver.parameter.port: auto
driver.parameter.vendorid: ffff
driver.version: 2.4.1
driver.version.internal: 0.03
input.current.nominal: 0.0
input.frequency: 50.0
input.frequency.nominal: 50
input.voltage: 222.0
input.voltage.fault: 140.0
input.voltage.nominal: 230
output.voltage: 222.0
ups.delay.shutdown: 30
ups.delay.start: 180
ups.firmware: IN01064B
ups.load: 9
ups.productid: 0000
ups.status: OL
ups.temperature: 25.0 <-- wrong and doesn't change
ups.type: offline / line interactive
ups.vendorid: ffff

The technical specs and manual wording and illustrations for my ups
and the one from
appear to be exactly the same, except for the plastic cover on the front.

Compare the two pictures
(no file extension, but is a jpg)

My printed manual has illustrations for more variants.

I still don't know who the manufacturer is or how to get anything more
out of it, but it's progress.
If I get anywhere snooping on the Windows drivers I'll post more.
