[Coco] Extended Basic Upgrade Options

[Donald Akins]

My CoCo is a 26-3134 16k Standard Basic. I ordered some 64k chips for it but needed the Extended Basic as well. Although it is tempting to order those 50pc 24 pin eProms mentioned in one of the emails I think from what I am reading here the 28 pin are more abundant and reliable. So if you can sell me a conversion kit that would be great! After that all I need to know is should I look on eBay for a inexpensive burner? Thank you, Don Akins

 Hi Don,
I have a 24-pin rom/eprom to 28-pin 2764 eprom adapter PCB I designed that could give you the capability of using 28-pin eproms inside your Coco 2.  Is there a 26-3027 Coco 2 or is it a 26-3127 Coco 2?  If so, I have a 26-3127 I can use to check for layout correctness.  I had made it to adapt the 24 pin rom socket in my floppy controllers to accept 28 pin 2764 eproms, but until now I have not needed to use it to adapt rom sockets on CoCo motherboards.  I'm on vacation at the moment, but when I get back home Sunday, I'll check it out for you.  I can provide the Extended Basic 1.1 rom you need also.  I thought you might what to know.
