Howdy all, Figured I should post this here in case anyone else wants to follow suit. So what is it I did exactly? Well, I took an 18650 (16650 works too for smaller areas), connected it to an adjustable output boost converter/lion cell charger circuit, and used this concoction to replace the...

I have a Socket 3 board that works pretty well. It has 128K of cache (can go higher, just need good chips to put in it), and supports up to a DX4-100Mhz. I've thought about it a bit. It does support a 40MHz and 50MHz bus. So, if you had the choice of either of these two CPUs: DX4-100Mhz...

While doing a random, late night ebay search (they're the best really), I found this: Your eyes are not deceiving you. There is a 34-pin Floppy port (pretty standard), a 40-pin IDE port, 15-pin "Game" port, 9-pin Serial port, and physical DB25 Parallel and DB9 Serial ports are on the bracket...

For those who aren't familiar with the Advantech PCA-6157, it's a Socket 7 Single Board computer with 4 72-pin SIMM slots, no onboard video, ISA and PCI backplane compatibility. I don't remember the exact spec name but it's pretty common/standard with the 16-bit ISA connectors first, followed by...

It took me forever to find this, thanks to Adaptec having removed it from their website before they were shutdown/absorbed. While at that point everyone was already using the Windows SPTI mechanisms for 32-bit apps, some of us may still want/need the SDK for writing older 16-bit DOS/Windows...

Hey fellow PC users! A long time ago, two decades at this point, I took the time to put together a bootable CD with the world's most convoluted series of nested DOS config.sys/autoexec.bat menus to get access to some commonly used utilities, speed up loading an OEM install of...

This is a bit more of a mini-rant at the rather abhorrent state and experiences I've had with the real mode drivers for Adaptec's older, non-PCI cards. Comments/suggestions are of course welcomed, more wanting to share my experiences in hopes that maybe I can spare someone else this same pain...

After having been alerted to a GoodWill auction for a Media Vision Memphis base unit, speakers, and power adapter in very good condition, I decided to get them, then go through the exercise of mapping out the pins to see if it's possible to build an adapter cable to connect most, if not all, the...

Hey folks! I have recently acquired a IIgs. I've already ordered a 4MB RAM card to replace the stock/original one and am planning on getting a ReActiveMicroDrive for it. I'm curious about what other expansion cards folks have or recommend. I'm using a BMOW Floppy emu, so I don't really need a...
