Use a flexible steel or plastic ruler.

Yea i was making it harder than what it really was. the ROM is 64kilobytes total, 32K in each chip. but each chip is on a 64K addressing system, so in theory it can address up to 1…

Wouldn't the curvature of the screen create a major problem in this scenario?

To start with, A0 selects the low or high byte ROM for 8-bit read, then A1 - A16 select the individual byte in each ROM out of 65536 possibilities or 64K, so 2 x 64K = 128K bytes o…

As mentioned, you want to be at 72 DPI, so display a page in MacDraw or MacWrite with the rulers showing, hold a real ruler against the screen and adjust to match.

Did you take the pram battery out? That solved most of my Pismo problems.

Awesome. I have a boxed 400MHz Pismo at work, but I can't get it to power on. It was a donation from a parent. I'm going to use it as a portable OS 9 machine because of some of …

GREAT listing, comrade! [] ]'>

Good call, thats what I get for not looking closely. Before Mode32 system software using 127MB After mode32 system software using 5MB. Thanks!!

The other major factor is that CRTs back then weren't as high quality, especially at the edges, as later CRTs. The black borders weren't just there for size considerations (they c…

Thanks so much for the reply beachycove! That unix sounds very interesting, will try that first. And the webserver, what a sweet idea! Will try that too. All in all I have to set…

well if i am not mistaking, it will see the full 128mb, but it will appear your OS is taking 120mb of it.

I wonder if that's why my picture started to get a little wobbly when I expanded it to fill the entire space, insufficient voltage... I looked it up, according to my Classic II se…

All B&W Compact Macs have a specified measurement of exactly 7.11" wide and 4.47" tall. This is based on 72 dpi, so that 512x342 should display WYSIWYG accuracy: an inch on…

I know in the service manual for my Classic II the last section that discussed screen adjustment said exactly how many inches in length and width the screen image should be for pro…

I've seen some that have edge-to edge and then seen some with a horrible border.

A collectable machine (or one that has been cared for and is in good condition), with all original accessories, ought not to be case modded in my opinion. Some alternative options…

specially considering you live in the hillbillie mountains

I won't lie, if you decide to gut the Performa, I'd be interested in the case for an ITX project, because I'm a loser that way. I still think this is a really nice haul, considerin…

I don't think it would collide with the tube if the floppy drive in particular weren't in the way. It might well do that if attached to the riser card pictured, however.

G'day - nice to have you here. Impressive Mac history too!

Your other option is to find or hack together a EuroDIN right angle connector and mount your second card sideways. Course, that involves moving stuff around... Check out this App…

na the drive hasnt been slammed as i am aware of. its a stepper motor drive. its a miniscribe 8425S? i forget. gotta tear it back apart and look. came from an SE

yes its in very decent shape for sitting in a puddle in a scraping shed / dump, I have a pic of the rear but its fuzzy and not that helpful, but none of the connections on the back…
