Will this unit work with the PEB?

I know, probably a dumb question, but I'm not a big TI-er. I have a few 99/4a computers here and one 99/4 along with 3 PEB units and I'd like to build up a nicely loaded 99/4 setup.

I also have a box full of carts and software disks... plus a couple of speech modules.

Thanks,

RJ

Yes.

It works with or without the PEB. You'll need the proper card and cable to hook the PEB to the expansion bay on the side of the TI-99/4a. The PEB's came with these. Check out the following.

There is a very active 99er community here.

Here is a site with some good info on the TI-99/4a

As noted, the /4 will work fine with a PEB as long as you have the Flex Cable Interface card--and there are no port differences between the /4 and /4A that could trip you up, so no worries there at all. It is a little bit different if you wanted to connect a 99/8 to the PEB--you have to replace the Flex Cable Interface with an appropriate Armadillo Interface card. I haven't run into any PEB cards that won't run with a /4 if they were originally intended to run with a /4A (though I haven't tried any of the 80-Column cards with a /4, so there may be exceptions there). All of the vanilla TI cards work: 32K, RS-232, The various DSSD and DSDD disk controller cards, Horizon Ramdisks, and P-Code. I think I even used a Myarc Personality Card for SASI Hard Disks once without issues (note this is NOT the HFDC, which came much later, and which I haven't tried with a /4, but which should also work fine--same goes for the WHT and SNUG SCSI controllers, they haven't been tested by me, but they should work with a /4).
