connector which looks very much like PS2 connection at the rear Looking at the manual that is a PS2 connection. It does not seem to apecify the AC Adapter voltage On the left side of the laptop there is a PS2 connection as well...just to add confusion. Definately not the smartest idea as it could …

2 days ago I was given what I belive is a 386 based TI Laptop.. Texas Instruments TravelMate 3000 WinSX Laptop Sadly there is no power supply and it looks like a possible muli voltage input connector which looks very much like PS2 connection at the rear. Obviously this will prevent any possibility …

My Portable III 286 is coming on nicely.. Having been successful with the modded bios and integrating xtide internally....I can now use CF cards. Here is a photo of the physical mod with the side mounted CF reader. Once I have aquired another 3.5" to 5.2" carrier/frame ...I will be fitting a 1.44mb …

Just unknown to me I guess.. certainly not so many for sale ...a bit of a relic I guess. I just searched and there are a few for sale but tend to be multiples.. I just want 1 for testing...after all ..it may be a faulty drive. 🤣

Today I aquired yet another Tape drive unit.. OnStream ? SCSI interface of course.. The actual tape drive was immediately identified by my early veritas software..and could well be functional. This unit is a little different to my usual encounters..mostly DDS 2/3/4 etc in that I have no idea what …

So ..looks like the hard drive issue is fixed...and I now have a working version of XTIDE in the basic unit...thus no need for the ISA sidecar in normal use.. These ISA slots could now be utilised for a sound card and/or a vga card. What I do find frustrating is that I'm restricted to 640k base …

Hopefully I isolated the right pin...as sadly they are not numbered on these adapters.. I have checked the pin I isolated with a meter in continuity mode. I have 5 of these which all receive the same treatment if confirmed correct. I'll be giving it a try shortly.. Tea and Toast takes priority 🤣

That specific CF adapter I see on the photo has the problem, it grounds IDE pin 28, which breaks the ISA bus logic on old PCs where the line 28 in the IDE cable exposes ALE signal from the bus. And it might even work seemingly ok, but make hw misbehave depending on circumstances. The copper around …
