I’ve just finished assembling my VT132 standalone kit from The High Nibble. It was an enjoyable build and pushed my soldering skills with soldering the tiny pins on the ESP32 chip. Initially I had issues getting solder to flow onto the tiny pins and pads, but I changed to a thinner tip which worked well.
Here’s a look at the board as it comes in the kit. I chose the option USB keyboard option instead of the default PS/2 keyboard connector:
Starting with the ESP32 first, here’s a look at my soldering on those tiny pins. I used the liquid flux, and the ‘drag’ method to pull the solder from the pads up to the exposed connector on the chip board:
Row of resistors for the VGA connector completed, and a few of the caps:
Almost done, just need to attach the DB9 and DB25 connectors:
First power on and looking at the settings. To access the ‘Set-up’ from a regular keyboard, press Alt PrtScrn. To view the onscreen menu help press F1:
More details on using the VT132 coming up in following posts.
I’ve just started work on assembling the VT132, a DEC VT100 compatible terminal. I got the standalone board, but there is also a version as an add-on board for the RC2104 computer. Not knowing anything about this, it turns out it’s a kit to build an 8 bit Z80 based computer that has expandable card slots for other add-ons. I might look at building one of these next, but out of interest I wondered what other similar kits are out there for building reproductions of retro computers. I noticed it’s not uncommon for some of these to only be produced in limited quantities and it’s unclear whether they will be available again, but here’s a list of things I’ve found:
Wifi232 – an RS232 modem that connects to your wifi instead of a real phone line. This was only produced in limited quantities but is well known in retro computer communities as an easy way to get any old computer with an RS232 interface online. More info here. If you search around you can find a few alternatives and similar kits inspired by the original Wifi232.
IBM PC 5150 motherboard kit – no longer for sale, but an impressive kit to build your own reproduction of the motherboard for the original IBM PC.
Apple 1 reproduction kit. No long available from Briel Computers, but check their link for other suppliers who may still be making the kit.
The release notes for World Update 2 look pretty extensive, adding plenty of additional detailed scenery areas. It’s interesting Davis Monthan AFB boneyard is one of the scenery update areas because I’ve been sitting on a collection of screenshots from flying over this area, so it will be interesting to see how much the scenery has improved. In the meantime, here’s some aircraft turned to stone and fused to the ground:
