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!

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.
