In fact, with a more sophisticated adaptor that allowed you to select the pin for the sync signal, the IIsi could support a VGA, SVGA (800 x 600), XGA (1024 x 768) and the Multisync monitors made by many manufacturers which allowed you to change rez on the fly.

Interesting, I could never get more than 640x480 out of my IIsi, must not have had the right adaptor. Great machine though, up until 2001 I had mine acting as a router/NAT sharing the modem connection on my home network.

The adapter that worked was made by Griffin, IIRC. It had DIP switches on the back and a big selector knob on the front. Back then various monitors had different sync pins and you had to get it right. I usually just used the basic adapter cause I had a lot of those and the software we were using worked fine at 640x480. I may be mis-remembering on the XGA support... that might have been one of the other II series... it's been a long time.

Shh, don't let your experience interfere with the hallucinations of the hard core Mac users. The manual says "built-in 8-bit video, supports 512x384 and 640x480 at 8-bits or portrait monitor (640x870) at 4-bits (uses 64-320 KB of RAM for video, not separate VRAM)".

Plus the Mac sites specifically state: "Internal video on the IIci and IIsi, and the Mac II mono and color video cards, will not work with multisync monitors, whether Apple or PC style. Griffin Technology makes the Mac 2 Series Adapter that works with Apple's Multiple Scan monitors and most Mac compatible monitors. There is also a version for using VGA-type monitors on older Macs."

The fact that you had to find this obscure adaptor, order it, and frankly it didn't work so well, should not interfere with your actual using experience.
