I have a 2FD 2000 and would like to get either your 'extra' 2000's with a hard disk or would purchase your HD controller. Has anyone have a ST506 HD larger than 10 MEG? I am porting MINIX (comp.os.minix) to this machine and need a HD. Tell me if you have ANY PARTS OR BOARDS OR SOFTWARE to trade. (I have Db3,Mword,MultPln,etc) Thanks: Please mail to snewton@donald.cs.umn.edu or snewton@ux.acss.umn.edu

You will need: 1) the HD controller card. 2) The HD cables (severely funky cables!) 3) the HD power supply (you see the power supply tunnel inside your 2000? Notice the "access hatch" in the top of it? That's not really an access hatch. If you have an HD, a separate (35 watt or so?) power supply mounted on the inside of the hatch cover goes there. This was Tandy's way of economy-engineering.) 4) An HD mounting kit. This is a bizarrely shaped metal tray that lets you secure the HDA into the space between the FD's and the power supply tunnel. The HD tray includes integral shock mounts. 5) An HD. I'm using a surplus DEC RD-52 disk (nominal 35 Megabytes, but I don't know how to tell MS-DOS to use past the first 10 Meg.) You need an ST-506 drive with BUILT-IN RAMPED SEEK!!! This is because the 2000 controller does not ramp it's seek commands and hence will "lose" the non-ramped disk (you'll get head-positioning errors that won't recover within 10 seconds of boot-up.) Good luck. Your project is doable (I did it!) but it's not easy. Please post a note if you get MINIX up and running on your 2000HD. Don't try and get away without the extra power supply, the mounting kit, and the cable kit. I fell down a rathole there for quite a while; if it's doable it's also a real pain.

HFORMAT /p < will cause the program to ask for number of heads & cyls. DO NOT go over 32 megabytes! HFORMAT /b < prompts for the 'bad track' data These can be used in combination with each other & the /s option. I am told this is buried somewhere deep in the owners manual.
