 The HAL Communications Corp HAL DS2000 KSR smart terminal. Click on image for larger view.
 The manual refers to this BMC monitor, so I assume it was purchased along with the KSR unit. Click on image for larger view.
 Here is a nice big pic of the boards and wiring view, with the case open. Click on image for larger view.
More pics What's next? Attach it to a computer expecting a current loop as if the HAL were a Teletype. There is also Morse code and Baudout communications. Reply |

ROM Dump for DS-2000 |
by Bill Degnan - 09/16/2025 00:09 |
 These are the ROM chips for the DS-2000. The 2708 ePROM is assigned to the memory space from 0000 to 03FF and the mm5132 covers 0400 to 1fff. Click image for larger view.
I used a Tantek Z80 in-circuit emulator to read the ROMs. http://www.tauntek.com Here is a dump of the two ROMS: DUMP Disassembly (let me know if the listing is usable, I did not test) If you're working on one of these units and you need to replace the mm5132 you'd need three more 2708s, for a total of 4 2708s. I have seen this done on other units, assuming a jumper or two needed in the back. There is space on the board for additional 2708 ROMs. I'd have to read the manual to see what the procedure is. Contact me if you need assistance. Reply |
