This Teardown of the V-tek TM-50 Manual Taping Machine Controller is a Work In Progress And a Live Blog Things Change So Keep Checking Back.
My ultimate goal is to get this to interface with my BPM Microsystems 3800 MK2 APS programmer and integrate it with a more compact tape-out system

Boards
TM-50 Main Board Part Number 105980E
As Removed Sticker Said Static (I had a brief conversation with V-tek this is a special version of firmware) Project # 617144 and most likely will need a new micro with different firmware. 🙁
Remove Revealing MCU 18F6585 PLCC68 There is also a 2416 at U10 Eprom on the board also that most likely stores user settings.
Regulator is a PT5101A
U4 is a MAX707
Q1-5 are NDS9956A Dual Mosfets.

I Attempted to backup of the Microcontroller it was Read Protected. Bummer no backup 🙁
Various Other Microcontroller Configurations settings.(Click Image to Enlarge)
I found a manual online, and it appears they sell the main microcontroller part number 102357. I’ll need to inquire about how to check the firmware version and find out the cost of a microcontroller that’s already programmed with the current firmware, in case a firmware update isn’t available.
U10 (No Backup Attempt) this prob just stores user settings.
I will Attempt to read this most likely it is read protected. 🙁 but been meaning to assemble the PLCC68 adapter for the Xeltek not had a call to read a PLCC 68 chip in a long time
Switch Board 105966
Solenoid Board 105982
Take Up Board (Will take Another Photo)
But Here is a Video
I attempted a firmware backup was also read protected
Repairability Score (Undermined) So Far a “C” Due to (Locked Firmware) But possible to get replacement chip from mfg. if so will revise.
Right to Repair Score (Undermined)
