I've had a couple of these displays on my bench for a few months now. I intend to perform more testing, but for now I've assembled a relatively comprehensive page of information here, so I can keep it organized as I update it: http://www.jeremywork.com/displays_ibm_bertha.html Hopefully this...

I picked this card up here from @herd a week ago, and I've been quite happy with its capabilities. I've had it installed in an MDD/FW800 with a Sonnet MDX/Duet 1.8 and its performance complements the processor speed very nicely. I was pleasantly surprised to find the 'top' port works as a...

I had this question when I was getting started, and it's come up fairly often since. In the case of Quadras it's generally good advice that onboard video will offer a better experience than any Nubus card can, excepting resolution/color depth or featureset. For this reason I started testing with...

I think my first post of this was lost so I'm re-adding the photos, plus I found a second loose card from Japan which is slightly different. This one's processor seems to have a removable daughtercard, but it seems to be stuck enough that I don't feel comfortable removing it.

I've gotten around to testing this board, which is advertized as compatible with Daystar's 'Quad 040' or 'Image 040' CPU upgrades which otherwise consume the PDS slot. It presents what looks like a second 040 PDS slot above the built-in one. I bought it sealed in retail packaging, though I don't...

I don't know why I forgot about this one, but it was another we lost last year. Here's all the source material I can remember posting, and some new since then. Back in February 2021, a seller liquidated what appeared to be the remaining cache of RMA and test cards from the inventory of Sixty...

I didn't mean to wait so long to post this back up, but despite losing the thread I think I have most of the attachments saved locally. Sincere apologies if any of this is misattributed. Hope it helps to have it back! --- I think @Nathan_A was the thread initiator, with a post about a Rev D...

Well I tried to recreate this faithfully but the posting system here won't allow posts over 10k characters, nor will it allow me to upload a docx file. For lack of a better idea, here's a zip of an HTML version of the word doc :/ At least everything from the top post of the old thread is in...

I noticed a number of official references to a Macintosh 19" Color Display (circa 1994, mostly in service manuals for the x100 series machines.) Supposedly a 1024x768 tube, though I can't seem to find any evidence that it ever existed...

I got extremely lucky this week and found a SuperMac Thunder II card, listed Buy-it-now on eBay for $30, sold tested to top it off. https://www.ebay.com/itm/SuperMac-Thunder-II-GX-1360-NuBus-Graphics-Card/283800247264 Unfortunately the packaging was minimal, and it lost a couple components...

I finally acquired a Reply extender for my DOS card- the original Reply card (without the Vibra 16 module, so maybe Houdini I) was also included with a Cyrix DX2-66, but several components were burned away on the back of the board, so I swapped it for the Houdini II with an Intel DX2-66 I...
