[vcf-midatlantic] FS: Interest Check: Tarbell Rebel S100 System

I've got a late-to-the-game S100 system I'm going to part with. It's a Tarbell Rebel -- made by *that* Tarbell, the guys who made the well-known cassette and floppy interfaces for the S100 bus. This is a much later system sporting an IEEE-696 compatible multi-CPU processor board.

The CPU board includes an Intel 80186 (one of those ceramic leadless packages in a Textool ZIF) and an 8 MHz Z80, as well as a few K of static RAM, a WD2793 floppy controller, 2681 UART, 8259 interrupt controller, and boot ROM. I've got the dual serial port breakout cable for the CPU board. Other boards include a Morrow HDC/DMA MFM hard disk controller and several static RAM boards. It's in a generic-looking S100 chassis with 8-slot terminated motherboard, linear power supply, and space for 2x full height 5.25 drive/ 4x half height. There are two half-height floppies installed. The case looks pretty generic, but does have "TARBELL REBEL" stickers on the front (not even silkscreened!). I have two full-height MFM hard drives for it, in an external disk box, which is also labeled as being Tarbell equipment.

The thing is, there is *no* documentation on the CPU board. I can barely find mention of this system in old magazine ads. I feel that, in that sense, it's probably worth more parted out. The S100 chassis is generic, but the power supply is good and the motherboard is terminated. I've used it as a test system with a Vector Graphic ZCB. The CPU board does *something* -- it'll seek a floppy drive to track 0 on reset, but I don't get a monitor prompt on either serial port.

So, is anyone interested in the whole system, with hard drives and all? Shipping will be a pain -- expensive, and has the potential to wreck the old MFM drives. I'll be at Festivus this year, so I could drop it off there.

Thanks,
Jonathan
