The 924 should be the
The keyboard controller is an 8049. Firmware not readable.
It may actually be compatible with the 955 keyboard, which I was able to read.
Key layout is the same, though the manuf is different

I did try reading it as an 8749. By 'not readable' I meant it re

8049s aren't protected. they are 2k versions of the 8048
and can be read as 8749s

Cool, thanks, Al! I'll give that a go.

When I saw this thread I thought 'Oh, I have a 925!' Which was working last
time (years ago.)
But wouldn't you know. When I checked, it's a Televideo 924. Off by one.
But perhaps the character ROM content is the same?
Anyway I will see if it still works, and secure all the ROM images. Today.

I was wondering what TS-8xx systems you have that supported RS-422,
and if you've dumped the firmware from them.
I can request the TS-806/20

I should be able to do that for you if you don't find someone else with a
dumped room sooner.

Hi all --
I'm working on a Televideo 925 terminal with a few problems, one of which
is a bad character generator ROM, (a MOS 2332). Does anyone have a dump of
this already, or have a working 925 they'd be able to dump the ROM from?
Thanks in advance,
Josh
