Great, thanks. I have those manuals somewhere at home. I haven't dismounted the drives yet or plugged it in. That's tonight. Rich Cini Sent from my iPhone...
It might be a pain, but if you have a chance to take a picture of the jumpers on the board, I'd be interested to see what you have. I just did a set of...
... Beautiful! I covet the 4/40. If I can ever pry it out of your hands with some tasty trade action, do let me know. -Dave -- Dave McGuire, AK4HZ New...
... I agree. When you flip over the drives, check the PC boards for a PC board number. Then you'll know which set of schematics you'll need. They look like...
... I had not realized, you (both) were using a custom one-chip tester. Also - what's "ISP"? I'm impressed with the effort you made, to program up a 6522 to...
Bill -- I didn't have time to pull both drives tonight but I did unmount the left-hand drive. Indeed it's a Shugart 801, SN# HV2633. As far as jumpers, DS1,...
Mike, I didn't see your link before and just took a look at your homebrew tester. It really needs some more work to tighten up the circuit before proceeding ...
... Create a ... Dan, I don't know if you read my most-recent post, before writing yours. Even though I also mentioned crosstalk and noise and such - frankly,...
... I think the 25229 sounds like a Shugart 800/801 board model number. ... the DJ2D-B is a decent enough 8-inch controller. Morrow docs are good. The...
HI, Boy, you guys are tough reviewers. :-) Other than testing speed, this test is about as complete as it can get. Signals look remarkably good, edges are...
I recently managed to find a NIB computer kit that arrived in today's mail. Â After carefully opening it, I noticed the 6800, 6821 and 6811 chips were sitting...

I generally lightly scrape the black gunk clinging to the pins with a knife, then swab them with a bit of isopropyl alcohol. If they don't break off during the...
"Goo Gone" did wonders removing some disintegrating foam insulation from an Apple Imagewriter printer i recently did some restoration work on. It still took...
... Even if they do break off flush with the IC body, it's possible to chisel away at the plastic package to get enough of the lead exposed to solder to....
My pristine original IBM PC green-phosphor CRT, the one with the SUPER long-persistence phosphor, just took a dive down a flight of stairs. I am pretty upset...
... Man, it was bad. The monitor was in a plastic bin, and was going down on the hand truck with two other bins. I lost my footing two steps from the bottom...
... At least it didn't hit you in the head (Hi, Sellam). I need a CRT for a DEC VT-320, because I stupidly tried to straighten one of the pins with a...
