I have four PEBs. Two were in regular use while the kids were home—last kid of seven left ~25 years ago. I have had one in more or less regular use until ten years ago or so. Since then, it has been mostly with nanoPEBs, when I use the TI at all—mostly for verification of fbForth cartridges and programs. These days I am constantly using Classic99 for all things TI-99/4A—mostly development or some programming challenge or other.

Haven't had a PEB box the last 25 years. Used a CF7+ for a while until I had 32k internal memory put in my machine + now a FinalGROM cart, and I'm all set.

No PEB for me. FG99 + SAMS 1MB+TIPI on side port.

There is a card for the PEB that i would consider to be my only reason of ever getting one: SID99.

I would love it if there was a way to use that from the side port without a full PEB.

PEB, tipi, and supercart with assembly programming and Forth is my thing these days.

My circa 1985 (close-out purchase) rocker switch PEB sat in the basement since 1993 or so. I took it out in January and found that someone (neither son will admit to it) disconnected all the 120V wires and connections. I posted a thread here for help getting it re-wired and finally figured it out. So I’m using that with my second (1985 purchase) beige console and all the cards (32K, TI disk controller and 2 half-height Panasonic drives, Cor-Comp Triple Tech w/ my original speech board, a Myarc RS232, and now a TIPI/PEB). Everything works great and I’m back using it regularly with a FinalGROM. I, too, love the massive PEB with its jet airplane sound.D93FACF7-5229-4C26-BAB2-7E6806726A67.thumb.jpeg.c10899b406ff18e70ba804b489426621.jpeg

I have a damaged PEB (that was damaged by DHL not knowing how to properly handle a large package), that I have been fearful to turn on.

 

I should make a monolithic replacement plastic top for my PEB, now that I have a printer large enough to do that with.

I have about half a dozen of them set up in various parts of my house, for TI-99/4A, Geneve 9640, SNUG 99/4P, and TI-99/8 systems. I use another one as part of my heavily-driven test system for use doing burn-in testing of boards that I assemble/repair.

I have 2x one for TI and one for Geneve9640. Also have 32k. 2x Nanopebs for standalone consoles.

Rocker switch PEB with two half-height drives, a Myarc controller, RS-232 driving an Apple Imagewriter and a TIPI. 32k ram is built into the console, so my 32K card is retired. I replaced the fan in the PEB so it no longer sounds like a shop vac sitting on my desk. FinalGrom or SuperCart at the other end. I like the blinkenlights. 

 

I also have a NanoPEB but found getting files into and out of the thing too cumbersome. Now it is in full retirement due to the console having built-in RAM expansion.

Many new things for the P-Box in the past few years, except a direct plug-n-play replacement switching power supply.

I have 2 PEB always 1 set up and running.

Just bought and installed Speech add in card, so Speech is now in PEB now and the new replacement card for Fire hose card.

One PEB time-share - used for hardware repair, /4a testing, and Geneve OS development.  Still has the original fan aka warning device and white noise generator.  5 minutes of inactivity and I can be out like a light :) 

The other system is a mid-tower ATX case with the PEB backplane/cage guts inside; was my primary system at home and during TI Faire excursions, but has been running Heatwave for the past number of years.  I was going to put HW into the PEB until I realized it is much harder to swap hardware in/out at a 90 degree angle.

I missed the heyday of the TI and its contemporaries by a couple of decades so my main PEB (older push-button style) is permanently set up, noisy fan and all. No modern amenities here! It's a basic 32K, RS-232, two disk drives setup, although it may get an HRD in the future to make E/A use a little more comfortable.

 

Also have a spare push-button PEB: cheap local pickup with 32K and disk controller, but missing the RS-232, flex, and drives. Sitting around in case I happen across a Geneve or an entire set of SNUG cards. I can dream ;)

off topic, but my push button pbox's switch is kind of sticky. Anyone else have this problem and have you found a fix?

Try deoxitizing it... I've only had issues with my ti-99 internal ps switch in the past, never the PEB switch. Are you in high humidity or stored the PEB at some time in a humid area? I suspect the spring is oxidized.

What if one modernized the PEB? I think that all cards can be made much smaller and all possible cards could have space within a smaller footprint. Or is it better to code it all into a Raspberry Pi? (if possible?)

If I understand correctly, there are some "half" substitutes for the PEB, or are there modern 100% substitutes for the PEB?

I have one standard expansion box, one rebuilt with less noisy fan, two half-height drives and some connectors replaced with connectors for Euroboard wire-wrap expansion cards and one home-built, which just hosts more drives.
