Thank you Lee. I am looking into it now.

[Vintage TI for assembly]

I have an opportunity to buy a TI 99/4A for a fair price. It does not include tape or disk drive. I can not find the edit/assemble cartridge on ebay so I am wondering what my options are if I want to play around with assembly on the TI-99 (cross compile or natively). The disk drives on ebay seem a bit expensive, would I be able to obtain an assembler on tape if I buy a tape drive and are there any solutions for transferring data from PC ?
