The only downside is that it is limited to 256k RAM (cf. the 512k >capacity if the Video7 FastWrite.) But 256k allows 640 x 480 x 256 colors and >800 x 600 x 16 colors, which is sufficient for our needs. > Some additional info: It's 640 x 400 x 256 colors, not the 480 I typ(o)ed above. I had to work to get it to play with my Adaptec RLL card: its onboard BIOS is addresses at the same place as is the Adaptec; the Adaptec can be rejumpered to relocate its BIOS. Then it works OK. Except you have to get creative with 386^MAX: assign region c600-cc00 as RAM or the Tatung gets confused (i.e., blithered display) in 43-line text mode. That took some work to figure out. The "Under $200" price: Eltech Research, Milpitas CA. (But remember I'm getting pricing on nearly 10 systems.) kEITHe

No way. It is impossible to get more than 409 lines by 640 on 8 planes with
256k bytes. Unless you have 9 bit bytes :-)
