Maybe try their old email address which was [email protected] - you might get lucky... The ISP, OZEMAIL, were bought out a few times, but the address might still reach a human...
Definitely need their software. Oztechnics were a prolific producer of electronic test and other gear back in the early/mid 90's here in Australia (about 20km from me actually). The board you have has the programmer piece, but also the in-circuit simulator. Both of which require their custom...
Was there ever any progress on new cards? MacEffects are out of stock and no response as to whether they are doing any more.. I have a Portable en-route, and I just learned from @alxlab 's photos above that it has the Technology Works card in it. w00t!
As an aside does anyone have any info on...
@JDW - yes good point. That screenshot above is from Speedometer 3.x from memory, so that's what I'll use for my benefit.
Will dig out the others you reference and document results with them as well.
Was planning to benchmark with Speedometer, but let me know if you'd like to see results from something different.. My stock SE/30 benchmark from previous test.
Maybe try just a few hours of outdoor sunlight if you only have mild yellowing to amend. Far more gentle and less likely to ruin your lovely machine. That’s what I’ve been using on my compact Macs and it’s slow but works great. See pinned thread.
No that's not it because the same Mac will happily boot from the same card in a different BlueSCSI. There's something whack-a-do (technical term!) with this BlueSCSI. But I tried a 20MB partition with 6.0.8 on it anyway. Same deal..
BUT, thank you for the suggestion - I'm clutching at straws...
Spent some time checking the PCB. All the connections between the BluePill, resistor nets and DB25 look good. Gave board another clean just in case. Nope. 🤷♂️
Right.. updated via ST-Link to the latest firmware.. No meaningful improvement. Device flashes quickly at power on, then goes to ~1 flash per second and Mac doesn't boot - just shows insert disk icon. Place card in another BlueSCSI and it boots up with no drama.
The log file from the failed...
You were right re the LIDO driver. I got rid of that and the grey pattern went away - and the story changed slightly.
All hardware is 1.1-a. I checked the resistance between a bunch of pins between working and non-working BlueSCSI and everything seemed OK (ie v.similar numbers for the same pin...
Eric, I pulled the SD card out of the BlueSCSI in question out last night and had a play on my Mac Plus (yes, with the TERMPWR mod) with another BlueSCSI I just finished building. Similar issue but this time the Mac wouldn't even finish POST - odd static pattern on screen. Hmm. I tried the exact...
Yup, original DRAM chips.. 35+ years of reliability then *poof* - outrageous! :) Anyway, here's the culprit. I struggled to get him out (ground plane!) so ended up snipping the GND leg and removed rest with flux and wick.
Put a socket in and a replacement NEC brand 64Kbit 150nS chip that I...
