TI-99/4A Expansion Questions

[Senior System Engineer]

Hello everyone,

I have 2 questions:

1) I know I can install two RS-232 cards in the expansion box for a total of 4 serial (using Y-splitters) and 2 parallel ports but can I install more than one 32KB card for 64KB or more memory?

2) Does anyone have a P-CODE card that they would like to sell...I've been looking for over a year and have not had any luck?

Thanks,
Scott

TI-99/4A FAQ: Memory expansion - arcadeshopper.com

The 99/4a came with 16k VDP ram on board. This is memory shared with the Video Display Processor and Basic. It can not be used for running assembly language or GPL programs. They run from cartridge or expansion memory. 32k ram expansion gives you additional memory for Extended basic, assembly...

"The 32k can not be duplicated in multiple cards/expansions so if you want to use another device that provides 32k you must remove or disable the existing 32k device."

I have a P-Code card with an undiagnosed fault (might be bad GROM, might be something else) I could send to a new home if someone were interested in An Project.

Hey Bear, I would take a chance and never mind having a new project. I'll PM you...Thanks

I have a new issue...When I try to format a 40 Track SS-SD Floppy disk, it takes about 10 minutes, goes up to about 340 on the counter, and then gives me a "Disk Error 41".
Anyone seen this issue before? Any help would be appreciated.
Thanks
