Hi John,
I was using my A1000 and an amiga RGB to VGA adapter to figure out which VGA monitors that I have that will support 15khz.
Only problem is that my A1000 died with an orange screen on boot and I read about diagrom's a1000 support for the bootstrap rom sockets.
Before I try it on the A1000, I thought I'd see if it runs in an emulator.
For some reason the files dated 16 july 2020 didn't work for me. I got the 2022-02-21 V1.3 beta version and that did work.
In FS-UAE it would run from the Kickstart ROM "Custom" setting.
In WinUAE it would run trom the Main ROM file: setting.
I thought I'd try it in MAME and hacking on the amiga.cpp driver I could get it to run:
ROM_START( a1000 )
ROM_REGION16_BE(0x10000, "bootrom", 0)
// ROM_LOAD16_BYTE("252179-01.u5n", 0x0000, 0x8000, CRC(76bd46ec) SHA1(2155b4887f064c5e01e0a2ebb4a0cc2a3e88d9e8))
// ROM_LOAD16_BYTE("252180-01.u5p", 0x0001, 0x8000, CRC(dd516b6d) SHA1(2c307d02f10ad332a479b50767fd0463efc2844b))
ROM_LOAD16_BYTE("diagrombetaeven.bin", 0x0000, 0x8000, CRC(b6842fed) SHA1(18bc6285869a8ccb9f2aac50e9204323d519d51e))
ROM_LOAD16_BYTE("diagrombetaodd.bin", 0x0001, 0x8000, CRC(d9fa0d68) SHA1(477a1e9f3c54dc1e88da1ffc3e53cd27414a048e))
==============================
But back to my original task of testing monitors for 15khz support:
It would be a neat feature to have a 640x200 resolution with some text to check monitor image quality, and a 640x400 interlaced resolution to check to see how the monitor handles interlaced video.
Maybe even have a setting with vertical and horizontal lines in a grid for image quality like Diagsoft Qapro (I had QAPlus/Pro years ago on my Gateway Pentium PC).
Before my Amiga 1000 died, I was able to get an image on these monitors:
Asus VH238
Asus VS248H-P
Dell E2214Hb
Seiki SE22HY01 Television
Sceptre E275W
I was able to get a non-flickering interlaced image on the Seiki SE22HY01.
