    Toshiba FDD6882-EIJ, 96 TPI but can only step to 40 tracks(?!)

    Has anyone seen this in the wild? It's an unusual specification. The jumpers match the FDD6881-H1R in the manual. Could it be that a resistor is malfunctioning, or is it intended by design? Disk reads and writes appear to be working fine otherwise, if the SuperCard Pro gives me any indication...

    The quest for the best cleaner formula for... floppies

    It's this same old topic again. We all appear to recommend basic alcohol solutions from the convenience store, but nothing appears to come well out of it. I tried 70% isopropyl alcohol on a sacrificial 3.5" disk that was in perfect condition. Half of the binder seemed to have disintegrated, and...

    Cheapest fair-quality and non-USB logic analyzer/oscilloscope?

    Going to get one as part of my Christmas bonus, so I am wondering if I should take something like a Tektronix 1225 or something else.

    ROM updates for NEC Ready 9618

    Does anyone have these personally archived? My NEC has a nasty bug with IRQs that prevents some tools from properly working and crashes Windows 2000 while booting, and even if you enable a workaround, that leaves everything except Windows 2000, which freezes at "Setup is starting Windows 2000."...

    Microchannel cards implemented in discrete logic

    I'm sure there were a few, but have they been collected into a list? The only ones I know of are the Roland MPU-IPC and my personal Future Domain MCS-350, which is of a very low serial number. All of the chips sans the EPROM and the RAM buffer are TTL and PAL logic. Some of the PAL chips look to...

    Super glue stuck in small SIMM socket, oozed all over

    In my wacky, immature installation shenanigans, I got Gorilla all over a RAM socket and did not realize it an hour until drying. It's everywhere; under the socket, in the pins, and over the board where the problem spot is. With a couple of rubbing alcohol, deionized water plus dish soap...

    5140 compatible LCD replacement

    Does any exist in the modern age that at least an industrial firm sells? Regardless of wacky prices, my original, never used LCD unit has lines down the screen; so, no go.

    Dealing with NIB software

    A new, completely unopened evaluation copy of Lotus Notes 4 has shown up in my collection. I absolutely have no use for this whatsoever, but I'm tempted to scan all the documents that are in there, including the covers. However, part of me wants to sell it and get it over with. The shrinkwrap is...

    1.8 uSATA mechanicals, want to buy three for cheap.

    I am planning to deal with $5 EliteBooks. Will take lowest capacity just for price's sake as long as everything passes DBAN and tests with zero bad sectors.

    Dynax DB-15, needs restoration

    Some plastic clips that I don't know where they go have fallen completely. Printer passes the magic smoke test and the mechanism appears to move around, but with no time, ink or the ability to restore this daisy wheel printer I have decided to sell it. Asking $100 + shipping.

    Mini 2133

    Any way that I can extremely optimize Windows 7 Ultimate for this machine? Disabling services and visuals won't cut it much while I'm still on the Basic theme. Firefox 57 is also a drab. Direct3D games also slow down to a halt, even when I enable maximum performance for quality in the graphics...

    What to avoid, or things that will fail... and fail

    What often fails so that I know what to avoid buying in terms of vintage hardware; in which not even a repair can be possible, or if it could be, guarantee a long term life? I already am steering clear of Jaz drives, SPARQ drives, and those epoxy power supplies from Commodore... Care to think...

    Apple //e MMU chip

    Will take the most fair offer. Am not willing to sacrifice the MMU from my working //e.

    //e fun

    Snagged me a //e without disk drives but a fully functioning monitor and a line printer for $35. This appears to be the B revision from 1983, as I checked on the motherboard and the underside of the computer. Currently, the power supply is dead; using a working supply brings me to finding out...

    Early copies of Works 4.0 and the Certificate of Authencity

    There is a certificate of authenticity sticker on my retail DMF copy of Works 4.0 that shows a half naked child pointing at a CRT monitor displaying the "Start" button on a tiled background with the words "Microsoft". Oddly, later shipments of Works 4.0 appear to include a different, generic...

    This is why I have a SuperCard Pro.

    A small teaser of what's in store; ask me anything if you will about this beauty. ;)

    Anyone willing to organize a parting?

    https://raleigh.craigslist.org/sys/d/ole-skool-computers-av/6515802975.html Trailer of old equipment; most of it is, well... vintage computer equipment. No PDP, IMSAI or VAX machines here unfortunately. Some of this stuff looks like it's junk, but maybe something good can be pulled out of here...

    Rubbish.

    Left a fresh, clean breadbin 64 running through a datasette tape. Typed the magic words, and took a break from the monitor. I then came back only to see that the text on screen had immediately garbled, the datasette could not be stopped and starting the machine again resulted in an orange...

    Huge supply of ThinkPad DRAM cards for $5

    They are all 32 megabytes, allowing models like the 755Cs to have an efficient amount of 36 to run OS/2 Warp 4. It's an insane amount of over 800+ cards; I wonder where the stock came from? http://www.primelec.com/smart-modular-32-mb-dram-flash-memory-cards-dram-cards-p2583373#.WohkcHxOldg Note...
