Does anyone have any experience with this? It is an 8 bit ISA interface card for 16-bit IDE drives. I have one running on my 1000tx. It is configured at address c8000 and irq2 (the tx can use either 2 or 5 depending on a switch). Using this, nothing quite runs. I think it is due to the strange video of the 1000tx (it is the Tandy "CGA", and gets its memory from the top of system RAM). With this card installed, and using a CP 3104 hard drive and Tandy's Dos for this computer, I have 2 32 Meg partitions. However, just about every piece of software causes the machine to lock up. If I install a WDXT-GEN board everything runs fine. However, I don't have any working st-506 interface drives. Any tips or suggestions? Kelly No virus found in this outgoing message. Checked by AVG.
