I recently received an MVS MV1FS 'cartridge holder' (great term used by the auction seller) in non-working state, the battery started a little bit of corrosion but the board itself is in pretty good condition. I've tested most of the points around the battery area and haven't found anything amiss.
The symptoms are:
With stock bios, slow click of death reset, with following graphics showing:
With unibios, fast click of death reset, no graphics displayed.
With diag bios, all tests pass, including Z80.
I set all dips to ON for the work ram test, which I guess works, it shows the text and sits there. I left it for a couple of minutes, but it hasn't fixed the booting issue.
I've also tried shorting the J2 to bypass the watchdog, but the board doesn't progress past the aforementioned states, it just doesn't reset any more.
Any help appreciated! The diag bios OK really throws me
