Re: Tandy TL/2

Yep, they were sold in UK Tandy stores, check out the last page in this PDF: http://www.dxarchive.com/mw/pdf/selected_pages_tandy_catalogue_1986-1987.pdf I'm not surprised they sold so badly here though. Tandy stores were always dysfunctional and as a kid I remember how unfriendly they were when I …

Tandy TL/2

Never seen one of these outside a Tandy catalogue so I couldn't resist. 286/8, 640K and the proprietary graphics/sound. Will probably move the 2MB EMS card from my XT over to this and maybe also the SB16. XT-IDE and a quieter fan mod also on the cards. It came with a Tandy-branded TTL monitor so it …

Re: IBM XT 5160

Update... managed to skip the floppy seek test by hacking the floppy BIOS. I'm fixing some minor issues with the 5153 monitor which look like they're down to a couple of bad caps. I also think the XT PSU needs recapped.

Re: XT/CGA laptop dissection

Looks great and great choice of game. As mentioned before you may want a slightly larger resistor on the sync output if you used my schematic. I bumped the sync voltage a bit for my particular TV. @StickByDos: Thanks for the partial pinout, will be great if you identify it fully. I've looked …

If you are interested in low-level hardware access from assembly in a retro context, the IBM PC & XT BIOS' are a great resource. The code listing is heavily commented. https://sites.google.com/site/pcdosretro/ibmpcbios Look at the commented assembly and the raw hex side-by-side to get a feel for how …

Re: IBM XT 5160

Cleaned the inside of the full-height IBM floppy and lubed the rails with some silicone spray. It's much happier/quieter now. Jeff has fixed write support on the HxC Gotek so all is good there too. The 8284 clock generator on my XT board is socketed, I've been playing with the idea of getting a PCB …
