content: Got myself a brand newCastlewood Orb Drivefor AUD$35. While it's not strictly "vintage", it's quite an unusual bit of kit and wasn't overly popular. The company didn't last long.

content: Ok, I got this:http://www.ebay.com/itm/Lot-of-64-AMD-AM9050EDC-GOLD-18-PIN-DIP-I-C-VINTAGE-78DC-/172825781594?_trksid=p2047675.l2557&ssPageName=STRK%3AMEBIDX%3AIT&nma=true&si=3i69NpAAx9Pw1X4XHf5H8cIYYn4%253D&orig_cvip=true&rt=ncfor a song (in my opinion). A pretty rare and sophisticated S-100 board. DRAM refresh totally implemented on the card with timed delay line. Much better description here:http://www.s100computers.com/Hardware%20Folder/TDL/32K%20RAM/32K%20DRAM.htmI also recently got this:http://www.ebay.com/itm/TB-1-Bob-Mullen-Bus-Extender-Board-USED-Vintage/201956439836?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649for well below the asking price (best offer). Another fairly rare S-100 test board and pretty useful as well. Description here:http://www.s100computers.com/Hardware%20Folder/Mullen/Extender%20Board/Extender%20Board.htm

He had the mother of all 1000 EX's from back in the day, he even had a rare external Hard Drive for it + the 720kb external floppy. I wanted it but couldnt justify a 2nd EX no matter how cool it was!http://www.ebay.com.au/itm/Tandy-1000-EX-/182727247733?_trksid=p2047675.l2557&ssPageName=STRK%3AMEBIDX%3AIT&nma=true&si=opuH%252B4pk33hInwltydb8FzUWuIA%253D&orig_cvip=true&rt=nc

Interesting you were running 8" disks though, i am sure we had a 5.25" HH, but then it was probably only 20mbsee if you can spot the manuals, you never know they might be the ones for the the NEC D2246 we just bought

content: I think the two floppy drives in the PC were made by TEAC. One of these was a quad density. This drive could store 720K on a low density disk. One of the two external floppy drives was a HD the other was the new 3.5". Upper right, you can just see the 20M Irwin tape drive.At some point, I bought a 386 accelerator card for the this computer. I think it plugged into the 286 socket and took one card slot. There was an article in one of the trade mags back then that had the design for one.

content: I bagged an Apple 3.5in External Floppy Drive (Model A9M0106) on ebay last night for $51 AUD - it'll make restoring my Mac SE a ton easier as 800k disks are a PITA to use, you can barely fit the System 6 on a single floppy with no room for anything else. This will allow me to put utils onto a second disk and avoid disk swap hell while trying to get my SCSI-SD HDD working.I kinda feel sorry for the 2 folks I was bidding against, I sniped the hell out of them with a max bid limit of $100 AUD with 2 seconds to go (yeah I really really wanted it).

content: For some reason I was thinking the SE had an internal high density floppy drive? Maybe that was a later edition of it? I know my SE/30 has an internal superdrive but that came out a bit later and was a high end machine at the time. That stuff was scary expensive back in the day.

The upgrade kit is like hens teeth these days.The 30 definitely had the HD drive standard tho.

Added bonus, this drive looks right with the SE styling despite being designed primarily for the II GS.

(Or is the yellowing mainly due to the light conditons in the picture in this case?)

content: Heat or UV will both do it. UV definitely plays a part though because I've had equipment that had a sticker on it that created a very clear shadow in the yellowing.Fortunately there are ways to reverse this to some extent. Mix some hydrogen peroxide with a bit of Oxy clean in a spray bottle, set the case out in the sun on a clear summer day and spray it down with the mixture. Keep misting it periodically to keep it wet and you'll be able to watch the yellowing vanish right before your eyes. Within about 15 minutes it should be substantially improved, that's what I did with my SE/30. Don't overdo it or the plastic will take on a chalky appearance that you can't fully recover. It will never be quite as light as it was originally but you can make it look WAY better than it was.

content: Quote from: james_s on December 13, 2017, 11:37:56 pmUV generates surface heat which causes the fire retardant to rise to the surface.Retr0brighting is pretty easy, you dont need sun at all, heat is all you need.for small stuff like keys I now use the stove top methodhttps://youtu.be/qZYbchvSUDYand for big stuff I put the items in a clear plastic tub covered with glad wrap - I use the Vanish Napisan Oxi Action for both methods as it's great at dissolving any surface oils or nicotine etc that may be on the plastic and gives a nice splotch free finish. I do dilute it a bit eg 50/50.
