emusonacid! legacy

Hi there, Paul @Zuonics here. My development machine ( which is an E4 Platinum) has stopped booting. When I turn it on the EMU logo appears, but the "Software: EOS v4.70" text box takes longer than usual to appear . When the text box does appear, the boot process then gets stuck, never progressing any further.

I was wondering has anybody else experienced a similar problem? I tried re-installing EOS 4.70 using ELoader but the problem hasn't gone away.

have you tried booting it from a floppy? maybe your HD is in need of repair/replacement. if you have any other scsi devices connected, maybe disconnect all of them and add them one by one?

Hi, thanks for your post. I opened the case and disconnected the HD and also disconnected all SCSI devices. No luck. I'm wondering is it a power supply problem (some component not getting enough) or maybe a ROM/FLASH problem.

I don't know about a power supply problem, I don't think it'd power up... sounds like repair shop time unless you have another one you can swap out parts with...

First thing I'd do is swap out the CPU RAM stick for another known-to-be-working one and see if it helps. Also, reseat the CPU Flash and all ROMs, connectors, ribbon cables, etc to rule out oxidation/chip creep/anything mechanical. If that doesn't help, it's shop time.

I recall hearing some weird clicking from the vicinity of the unit, so I turned it off. Powering up again the problem appeared. Unsure what's up..
