All my excess hardware lives in an old pinfeed printer paper box that a friend in Seattle gave me when I gave me a bunch of his stuff years ago. All my cards live in there as well (I don't have a lot of cards, I prefer to fix stuff up these days when I can).
Last night, did even more work on the Tandy. V20 is working, and I FINALLY figured out why Ultima V and Ultima VI were not running (and Castlevania) - because my XUB (XT-IDE) was conflicting with the Tandy's CGA VRAM. Apparently some part of the old version I was using was leaking into the CGA/TGA memory space. Once I upgraded to the latest release using IDE_XTPL.BIN, no more issues.
Benchmarks show the V20 being faster than a 6MHz 1000EX which is a bit surprising to me. Also explains why this thing feels more like my first computer (1000 SX) now.
And finally, the 8087 shipped, ordered it on the 6th, went out yesterday. So soon I'll have that. I have some games that use that (CYAFT, MSFS, Sim City), and I think DOSLynx can leverage it as well.
