I found MESS's emulator used 50146 (european) font ROM with Tandy 1000 emulation.
But it is wrong emulation.
Because, tandy 1000 has character font on Main System BIOS ROM.
So delevoper doesn't have to add 50146 file as font.

This is screenshot between mess(non original) and tandy(original) font.

Each Original character font is located on System BIOS area.

Character Code (000-127) : F000:FA6E ~ F000:FE6D
Character Code (128-255) : various from each system


1.Mess's 50146 font on Tandy 1000TX BIOS(01.03.00)

2.Tandy's Oiginal font(rev.1) on Tandy 1000HX BIOS(01.03.00)

http://www.mediafire.com/?5dgfgledl3crr4i


3.Mess's 50146 font on Tandy 1000SL2 BIOS(02.00.00)

http://www.mediafire.com/?16w9i1wz0dxjj58


4.Tandy's Oiginal font(rev.2) on Tandy 1000SL2 BIOS(02.00.00)

http://www.mediafire.com/?1ehi5q0sa5egghb



Font (Rev.1) : Tandy 1000 / 1000A / 1000HD / 1000EX / 1000SX / 1000TX / 1000HX

Font (Rev.2) : Tandy 1000SL / 1000SL2 / 1000TL / 1000TL2 / 1000TL3 / 1000RL or later


Mess doesn't have to add and emulate 50146 font.
But it not possible to emulate without font file, I've attached font 1 and font 2 files for emulation of Tandy.


01-0X-00-FONT(2KB).ROM
--> Original Tandy 1000 Font (Rev.1)
(http://www.mediafire.com/?ujsor1kumragie4)

01-0X-00-FONT(4KB).ROM
--> Original Tandy 1000 Font (Rev.1) for MESS emulator
--> Rename this file as 50146 to use font correctly.
(http://www.mediafire.com/?b338v80bq7pnquc)

02-0X-00-FONT(2KB).ROM
--> Original Tandy 1000 Font (Rev.2)
(http://www.mediafire.com/?bb4m5b3q19uvns1)

02-0X-00-FONT(4KB).ROM
--> Original Tandy 1000 Font (Rev.2) for MESS emulator
(http://www.mediafire.com/?ieg7nf9gie5q9a7)


But anyway, MESS's 50146 must be deleted or replaced with original Tandy 1000 font.

For about Tandy 1000 fonts, refer the following sites.

I really want to know MESS still uses non-original Tandy 1000 Text font with "8079027.u36"

What is "8079027.u36"
I've run Tandy 1000 emulator of MESS.
But all text fonts are different from original Tandy 1000 series machines.

I wonder who decided to use "8079027.u36" as Tandy 1000's Font ROM.

At least developer doesn't know about Tandy 1000 character fonte.

Tandy 1000 doesn't use CG Font chip set seperately.
Default text font is included on main BIOS.

Do a google search for tltech.pdf, scroll down to the schematics, look at location C1, there at U24 you will see a 16Kx8 rom listed, that is 8079027.

If you look in the parts list just before the schematics you can see it listed as something with part number 8079027.

If you're right, why the default font for Tandy 1000 emulation is different from real machine?

The reason why :

1) Bad dumped or different dumped one from original CG chip set.

2) Good dumped one, but Tandy 1000 doesn't use Text font via CG chip Rom but from Main BIOS.

I've checked the each machine's main BIOS.

Which Tandy 1000 machine are you using for reference?
The Tandy 1000 series covers quite a wide range of different machines.

I've been meaning to get that 1000A motherboard out to someone to get it dumped. I guess this'll give me one more reason-- getting this settled.

By the way, it also wouldn't surprise me if there are bugs in our current t1000 graphics emulation.

This is various IBM PC related text font site.

http://int10h.org/oldschool-pc-fonts/fontlist/#ibm_pc_bios

http://nerdlypleasures.blogspot.kr/2015/04/ibm-character-fonts.html

You can see Tandy 1000 series font.

I've checked the text font from MESS's Tandy 1000 emulation via 8079027.uxx

I wonder 8079027.uxx is real font rom file.
(Because it is different from Tandy 1000/1000A/1000HD/1000HX/1000SX/1000EX/1000TX font.)
