The Mean-Well Power Supplies

You need TWO: "RS-25-15" for +15V and -15V
Digikey.com or Mouser.com or JameCo.com

and ONE: "HRP-75-7.5" for +8V
Digikey.com or Mouser.com or JameCo.com

DigiKey.com is one source for the power connectors

Setting up an FTP to add/remove Files on the ESP32 FDC+ �SD Card

Open your ftp client:
Site name: Your Computer Name
Type of connection: FTP
IP Address: 192.168.0.56
UserID: fdc
Password: fdc

Connecting to the WiFi for ReConfiguration

Open TeraTerm

File � New connection Alt+N

Set Up Terminal

The Console with TeraTerm

Connect Port 0 from the 88-2SIOJP board to the PC via a RS-232 to USB adapter cable
Use the "Device Manager" to identify the COM port used by the RS-232 adapter cable . . . . .

Install and SetUp TeraTerm on your PC
< Setup > - < Serial Port > - < Port: >
Enter the COM Port number from the Device Manger . . . . .

< Speed: > = 9600

< Transmit delay > = 10 and 100 msec/line . . . . .

After "RUN"ing the BOOT from FFOO
On the PC/TeraTerm display you will see;
...

You are at the CP/M Prompt
. . . . .

From here you can type DIR or LS to see the files on a drive
. . . . .

The command line to run MBASIC from the A: drive and the GALAXY.BAS program on the B: drive
. . . . .

BOOTing to the Console on the PC
.

Connect Port A from the 88-2SIOJP board to the PC via a RS-232 to USB adapter cable
Use the "Device Manager" to identify the COM port used by the RS-232 adapter cable
. . . . .

Install and SetUp TeraTerm on your PC
< Setup > - < Serial Port > - < Port: >
. . . . . Enter the COM Port number from the Device Manger
