Timex/Sinclair 2068 Cartridge Boards
by Al Hartman 10 Nov '15

10 Nov '15

Mark Blair (NF6X) designed Cartridge boards for both the Tandy Color Computer, and the TS-2068 Computer. I ordered some of each. The bare PC boards from OSHPark arrived yesterday. I built one of the TS-2068 up today, and will be testing it with a Spectrum Emulator EPROM and an OS-64 EPROM (I have ten of these chips from Zebra Systems, and have permission to make more. OS-64 give a TS-2068 a 64 column screen.) I had to order a bunch of boards to get a decent price. You have to buy three at a time from OSHPark. In that quantity, they come out to a little under $19.00 each board. So, I have a few extras. If anyone on the list is interested in a TS-2068 Cartridge board, I can offer single bare boards for $20.00 including shipping in the Continental U.S. Only. Add $5.00 more for a kit of all the parts to build one up. I haven't determined the price for a board built-up with OS-64 or a Spectrum ROM yet. But it looks like it will be around $35.00 shipped. You might want to build your own, as my soldering skills are far from expert and I'm sure there are many on the list who do cleaner work. I can ship bare boards, and kits now. Built up boards will take me a little time to make and test. https://oshpark.com/shared_projects/6ihON5Uq CoCo Cartridge Board: https://oshpark.com/shared_projects/aMK1Ekos I'm using the Coco Cartridge board to make an HDBDOS cartridge to boot Drivewire (use a PC/Mac/Linux as a disk server over serial cable) without needing to CLOADM a wave file with the software. Eventually, I'll dig up my Coco Disk Controller that can switch between two ROMS, and have one be a standard Coco Disk Extended BASIC, and the other HDBDOS. Since there are separate versions for the Coco 2 and 3, Mark helped me make up a file with both versions so I can bank switch between them using a 27128 EPROM. -[ Al ]-

Reminder: hoodie orders
by Evan Koblentz 10 Nov '15

10 Nov '15

Repeating the original message... ---------------------------- We are ready to take orders for the Federation hoodies. They'll be black with front pockets and (obviously) hoods. Design will be our new logo on the front. Only change is the keys won't have the gray shadow, because that would be a third color and too expensive. Speaking of prices: Small through XL = $20, 2XL = $25, 3XL = $30. All are men's sizes. Kids/womens/or anything bigger than 3XL not available at this time. ***** VERY IMPORTANT: ***** - All orders MUST be placed by next Friday (Nov. 13) at 5PM ET. At that point I'll email our order to the shirt company. Procrastinators will have to wait for another batch some other time. - You must prepay. Hoodies are too expensive for us to lay out the money and chase you down for it later. Acceptable methods of payment are through PayPal (hoodies(a)vintagecomputerfederation.org) or send a check to Vintage Computer Federation. Our address is P.O. Box 417, Eatontown, NJ, 07724. - Put the sizes and quantities you want into the PayPal comments box or the check memo field. - DO NOT say "I'll take size XYZ" in email (to me, the list, or wherever) and expect us to fill that order. Follow instructions above.

FS: Interest Check: Tarbell Rebel S100 System
by Systems Glitch 10 Nov '15

10 Nov '15

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

> I think there should be a section for important processors. There are lots of exhibits that we should have, but we will weigh space vs resources. I agree with the wall-mount ideas.

FS: National Instruments LAB-NB NuBus Analog/Digital IO Cards
by Systems Glitch 09 Nov '15

I've got two of these: www.ebay.com/itm/272041267556 I don't have any NuBus Macs, so I'm unable to test them. They're in good condition, a little bit dusty. These will work with LabVIEW 5, the last 68k version of LabVIEW, which is available through several popular Mac abandonware sites. Thanks, Jonathan

I don't think anyone is. But like I told Evan. I think there should be a section for important processors. The museum should have a section with important CPUs such as the Cosmac. ------ Perhaps a wall-mounted picture frame type display with various processors in it?Just a suggestion. Christopher.
