Found this piece of paper for the above mentioned speed displays in an old case, useful for minuszerodegrees!

I thought I would make a separate thread for this new system i got (mentioned in another thread about the psu). I recently got a an Intel i661 chassis and it came with a manual (145340-001) but I wasn't able to find this online so i scanned it myself. It is just JPGS though so it needs turning...

hi all, Just picked up an Intel i660 (Multibus) chassis with a bunch of cards but the psu is bad. I am figuring it out, but would be nice to have a schematic.. seems like my chassis/PSU is from 1978 but the rest of my SBC cards are from late 1984.. any hints appreciated!

hi all, I have an LED mhz speed display in a case I am building right now marked TD-38S , I did not see listed on minuszerodegrees, but several that are close. I used K-568 for the diagram to help me suss out where the normal and turbo pins were for each unit. I took photos of the group of...

hey all, Just got a Texelec Quadflop and was having a hard time getting it to work with my Faraday MicroPC SBC until i mapped out the address translation table for their DIPS.. they have the address translation swapped for R1 and R3 i think. see the following image of the address table i made :

hi all, I have a Teknor AT4 single board computer (486sx33), and from reading the manual there is a utility called 'xflash' that is used to manage the flash memory that is used to boot the computer as if it had a disk in the A: drive. The SBC i have is programmed with proprietory software...

hi all, Recently acquired this board and am still puzzled as to its function and purpose in life. I can't find any detailed information anywhere that I can see - just a listing for the company in a PC magazine from BITD (but can't see the original source page). Looks to have Z80H but no...

I found this ISA card recently and thought it was an EGA video card because of the DE-9... Etched with : 61-020066-00 and screned with NT2V0 DC 9046 #515001-01 Turns out it is a single-board computer. I went to the local junk shop and got myself an ISA backplane and once I plugged in a...

hi all, Found this weird ISA card recently, dates to around 1990. I wondered if anyone had the software for this - I understand its an on-the-fly disk compression system which sounds rather nifty. Also seems like it works for Dos 3.3 or thereabouts. Any help appreciated!

While i was copying the driver disk for another card, this one was next to it, so i figured i had better copy the contents over too. No idea what the card is/was/looked like though. Hopefully of use to someone, has RTC utilities and a spool thing.

hi all, Picked up a system the other day with a working RLL setup in it, using the Adaptec ACB-2070A and a Seagate ST-225 (yup, works great, zero errors!) The ROM at 7C differs from what I see on minuszerodegrees so i dumped both to check the existing one too. 7C rom label : 490043-00A...

hi all.. I have a Four Phase Systems IV-90 CPU board that was never loaded with components. Super rare i would say! http://www.andysarcade.net/pix/AA02695P.JPG Want to make an offer on it? My interests are s100 computers and early video gaming things (pre 1977) for trading or whatnot...
