That's the problem, the is no resident BASIC on board. Remember this is at the moment an S-100 machine that just happens to have a V9938 chip and 128K RAM.
Is the "register view" actually from your current system. Would like to see the above display with the chip configured to Text Mode 2 (80X25).
openMSX guys: How to I redirect the output of the command "vdpregs" to a file? (or any console commands, BTW)
I usually redirect it to stderr and copy/paste it from the terminal I started it on.
puts stderr [command]
Have heard no further comments on this tread.
I'm still trying to determine the appropriate values for an 80X24 (V9938 Text mode 2) screen display to place in the V9938 registers.
Could somebody with an MSX functional system (in 80X24 char’s mode) bring up the openMSX-debugger and get a dump of all the V9938 registers (“VDP registers view”) and post them here.
Would help me a lot.
Thanks
John

just one question: monahanz: why didn't you just run openMSX with debugger yourself?
Thanks PingPong, will check that combination out and report back. Give me a day or two.
Manuel, I assumed I could not run openMSX on a non-MSX machine. Currently the only hardware that is MSX on this S100 system is the V9938 chip. I can run CPM however. Does open-MSX run in any CPM box?
John, you should swap A6 and A7 lines so that VDP's AD7 goes to A6 of the DRAM and VDP's AD6 goes to A7 of the DRAM. If you have proto board the best is to cut two vertical conductors at the bottom which go from VDP to the U13 and rewire.
Interesting, is this a unique feature of the MSX hardware. if so why? Would never have guessed!

outputing the row number one time, then several times the column number? nah I don't think so, anyway weird that it requires a custom Address bus connectivity if that is.
monahanz: openMSX is an MSX emulator for modern PC's, handhelds, Macs, etc. It's not MSX software....
