Thank you, Tom Lee. I PM'ed Wally to see if he's willing and/or able to contact the sister about the source of the CRT connectors. Of course, the only hope there would be if there's still an invoice or other purchase record available, unless Gamba kept notebooks or such.

I've been mirroring it for a couple years now at http://www.fenestrated.net/mirrors/ The more mirrors the better!

I have no time for old Macs now, but I still love them in my heart.

I retain some of Gamba's design notes, at least those that had not been given away to others before I met his sister. The only CRT socket info I can find in his notes is APCO EIA-1210, which does not search well. The pins are the regular 7 pin miniature tube socket spacing so various sockets from Antique Electronic Supply or your favorite surplus source can be designed into future video board creations (edited addition: PROVIDED the socket design allows modification to clear the central CRT glass stem!). I found no order invoices and believe he was recycling sockets from Mac video boards (he had quite a large box of them that got freecycled).

Resistor/capacitor arrays (filters) and right angle Euro-DIN connectors: Both of these he had ordered and received from C&H Distributing, 215 S. George St York PA 17403 (800) 577-1175 (717) 843-7881 in the fall of 2002.

Additionally I have some design info and master artwork files for grayscale adaptors and the IIsi/IIfx ROM board that someday can be made available. As far as I can tell the Daystar PAL was of interest but never reverse engineered, but the right angle connectors were useful in various stacking options.

Gamba's sister is engaged in a struggle to retain independent living status, and prepare for the time when this is no longer possible due to age related health issues. I respect her priorities which at the moment do not allow her to devote time to drafting a memorial page. It is her wish that the work of Gamba be preserved and made freely available for future vintage Mac enthusiasts in a non-commercial and respectful manner. I believe that those of us willing and still able of mind and body should find ways of preserving Gamba's work and honoring his memory ourselves.

Those with a determined historical research interest should also use the wayback machine to visit the now defunct site http://www.accesscom.com/~gamba/ to see the original site. Be diligent about using the time machine to check out seemingly broken or unarchived links.

When I became aware of Gamba's death, I considered putting up a mirror of his site (I own a copy), just in case. I didn't do it because I learned that his sister was continuing to pay to retain the original. The greatest thing about Gamba's site is the density of information. If you are a knowledgeable enthusiast, you can drill down and find the information that you require without fluff and annoyances. When I was designing my own web pages, I took lessons. After a couple of year's of non-maintenance, the problem is that Gamba's pages have too many broken links. And links are the biggest problem for any web site maintainer. As we approach the fifth anniversary of his death, perhaps it is time to update the content elsewhere in memoriem. In traditional Gamba style, of course. There is no rush. We have all (northern hemisphere!) summer to think about an appropriate commemoration.

I'm new to the forum and never heard of Gamba till now, but I'm very sorry to hear of his passing. I was kind of curious to get to know him through his website, but unfortunately there's no personal info there. While browsing his site, however, I did realize I'd been there before fairly recently seeking info on the "homemade grayscale adaptors" he mentioned. Wally, I don't suppose you would be willing to share with me the info you have on that.

Thanks to ~tl kindly modifying our forum to allow asterisk characters in tags, I am now able to provide you with a direct link to the Original Gamba Website (2000~2001), which Wally brought to our attention here.

That original Gamba site also alerted me to this [url=http://home.earthlink.net/~gamba2/tamingNN.html]Netscape 2 Taming Page, which I have found to be of great interest. I learned long ago through my own testing of various browsers that NN2 is the absolute fastest browser you can run on your 68k Mac (under System 7). And so this Gamba page is very helpful in reducing crashing and instability to a minimum.
Kudos, Gamba!

Corrections from gamba's engineering notes: R6 on the Micron version of the video board is actually a 20K and R5 is 560 ohms. His hand marked up schematic says Q1 emitter current is 2.8 mA max.

Wally, thank you so much for taking the time and effort to research these matters and for sharing the information with the rest of us.
