"The TC5332204 mask ROMs have a similar pinout to the 27C322 EPROMs. The only difference is that they're set to byte mode only: half of the data output pins are unused. Pin 30 (Q15) is used as the address lowest bit."
And that while the 27C322 are 16-bits mode only, the TC5332204 are used in 8-bit mode.
Maybe you are right, i can try to read them as 27C160 that are 8-bits mode compatible.
When searching online, I've have found the following way to copy the content of the rom which required some tricks for the reading and then a rebuilt of the rom. This could work for me at the end if there is not other solution but as i just want read/check the rom i would be more than happy to spare that procedure.
" 1-Connect Pin 30 (Q15) and Pin 22 (Vcc) with a test lead. Then dump as M27C322 to a file v1_vcc.bin 2-Move test lead to connect Pin 30 (Q15) and Pin 12 (GND) instead. Then dump as 27C322 to a file v1_gnd.bin 3-romwak_x64.exe /b v1_vcc.bin split1 split2 4-romwak_x64.exe /b v1_gnd.bin split3 split4 5romwak_x64.exe /m split3 split1 v1.bin "
I'm wondering if reproducing the same procedure when using M27C160 instead of MC27C322 coud allow to spare points 3- and 4- ?
