seequa.org for my ever expanding research on the Seequa Computer Corporation
Wait wait wait. Revision J or M motherboards? I’ve only ever found revision J in any Chameleon I’ve seen. I wonder what revision M changed?

Check out this cap of a Computer Shopper from 1987: Chameleon Schematics, Short Stuff expansion cards, and bare motherboards! Would love to know if anyone picked these up.

Posting here alongside my Mastodon ([email protected]), the Seequa Chameleon also allows for customized CGA color palettes via an OPTION program! Here is Alley Cat running in red white and blue, straight from composite!

I believe so! With data retention of a hundred years! At least… in theory I guess I don’t know how they supposedly measured that lol

Did you know the 1982 Seequa Chameleon could save BIOS configurations via a DOS program? If you’re thinking it did so via a button battery, you’d be wrong! The Chameleon used this dinky XD2210 64x4 NOVRAM memory chip to store it!

Thanks to @gloriouscow.bsky.social for finding this!

Every single Chameleon has those two wires, plus every bodge on the back is unique per Chameleon. I have some older photos of production where those wires are very visible.

Does anyone happen to know what is up with the Zorba timeline? I am working what I thought were the only three Zorba models (Telcon, Modcomp, Gemini), but I found something called a "Nomis 9", and other models? I feel like this is more complicated than it needs to be, haha!

I was able to get in contact with the EVP of Seequa, and a care package showed up at my door. Probably a days worth of scanning in here.

Friday at 8PM EST we will be going through all of these and updating history in real time over at twitch.tv/mcjonestech , I hope you can join!

I stepped away from my booth for ~5 minutes or so Saturday, and when I came back Natalie said someone asked if she was the Macintosh Librarian (surrounded by CP/M and DOS machines, lol). I am so glad I found the live stream where this happened, she said to me "I wish I was that cool" #vcfmw

Ohhhh I am very much aware. I took on getting a Chameleon and its younger brother the Chameleon Plus restored a few months ago. At least they labelled every chip. In my very large amount of research I’ve conducted on these, the people that assembled them had never seen a computer before.
