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 …

This is a 240V version, I guess they sold a few in the UK after all. There's a HX on UK eBay at the moment if you're interested.

You may be able to disable the password check using the PS2.EXE utility. This also allows you to set various other configuration options. ftp://ftp.lanet.lv/pub/windows/lanet/thinpad/uttpg101.exe

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 …

A very generous seller threw this monitor in with another item I bought. I believe this is a Philips CM8833 variant, just with a single input and without separate composite/audio input. Has SCART and RGB TTL input, so should be good for CGA/EGA too. Connected to my Amstrad CPC in these pictures. …

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.

RS is worth a look too, they also have free UK postage. Their minimum unit requirements are often higher than Farnell though.

Nice work! The CMOS battery is located under a cover to the left of the removable floppy (not the blue standby battery pack). If you disconnect it that might clear the password. If you do find either the Dock 1 or 2 it has a built in PSU. I've only been using this with DOS so I haven't got any …

I can't see why this wouldn't work, as long as the game doesn't interleave digital sound DSP commands with MIDI output. Flashback on PC works with SB-MIDI and digital sound. Test it out and let us know what happens 😎

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 …

Good find on the 370C. Hopefully it will work when you get a PSU. 486 Thinkpads with a decent TFT screen are not that easy to find, there are a lot of mono or DSTN models. The docking station is the Dock 1 (3545). www.thinkwiki.org/wiki/ThinkPad_Dock_I_(3545)

I believe it's the same as my 370C. There's a program called PS2.EXE that's used to set the CMOS settings, including screen scaling. I even found a link for you. http://support.lenovo.com/us/en/downloads/ds013835

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 …

IMO a CRT is important for DOS games, it's part of the experience. Ideally a shadow mask and not flatscreen too. Have a 17" Philips which I use for most things, and an IBM 5153 CGA for the XT which needs attention. Also keep a 14" TV with SCART handy for my Amstrad CPC.
