[vcf-midatlantic] Timex/Sinclair 2068 Cartridge Boards

[Al Hartman]

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.

CoCo Cartridge Board:

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.
