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 (mcjonestech@oldbytes.space), 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!

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!

Successfully dumped the ROMs from this absolutely disgusting Seequa Chameleon motherboard. You can see how clean it was *supposed* to be, underneath.
Turns out it was a version with no prior good dump, so that's cool!

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!

One of the cool things I saw at #VCFMW was the Seequa Chameleon at an exhbit by @mcjonestech.com
This was a series of PCs that could switch between a Z80 and an 8088 CPU.
Conspicuously lacking ISA ports - there's a CGA integrated onto the board (note the MC6845).

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
