What is it? I'm guessing its some kind of disk controller. Does anyone have specifics? -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org>

you never know what you can find if you just ask

by chrism3667＠yahoo.com

I wont say exactly for what, but I have in my possession about a dozen brand new crts for a popular old puter. It was a lucky and unusual find. Not for sale at this time. Sorry. Having said that, I would like to acquire some 9-13 inch new color crts for *far distant* future projects. They need to be high-res computer grade capable of displaying 3-475 lines of res (is that even a function of the tube?).

These tend to power on with the opposite value that they were programmed with. The data looks scrambled but just inverting the values will recover a large percentage. Dwight

Adding numeric keypad to LA120-AA?

by legalize＠xmission.com

My LA120 is the -AA model but I'd like to see it "upgraded" to include the numeric keypad on the right hand side. Does anyone know if this is possible? -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org>

HP triple bay rack seen

by compoobah＠valleyimplants.com

So, what's a good way to roughly approximate the "value", especially if it's the sort of thing that is in the "cool, but I've never seen one before" category? I assume for scrappers that don't do parts sales it would be a weight thing? What do some of you regulars offer? (My brother in law works for a scrapper/recycler, I thought it was PCs/printers, but one day he was over at dinner talking about pulling out these "huge disk drives and modems" I thought I'd see if I could talk them out of some bits . . .)

what about asics, fplds, fpgar, vlsis (the latter being of most interest to me), etc. etc. etc. Can those be readily reverse engineered. Say you had a *bad* vlsi, and a block diagram of its innards. Could the *details* be worked out, and would it be feasible to reproduce it as an fpga? --- cctech-bounces at classiccmp.org <ard at p850ug1.demon.co.uk> wrote: > > (and contents) when it was removed from the circuit.
