I take that as a compliment 😎 if course, as Louis Rossmann would say, when you got paying customers, unless they want to pay more than what the board is worth, you swap it out. But, if you want to use it as a learning expirence. You can play with it as you have time.
I wonder if the clock oscillator has failed. there are two of them near the MC68000PB chip. Does anyone have a schematic for this board? Would make tracing the problem a bit easier.
Also there is a Merlin 2 diagnostic module on Ebay. would this help to determine if the clock has gone bad. or...
Possibly. may be possible to connect a Data packet sniffer to the Rs232 com port and check the RX/TX data lines. I know it is set for 2400 8N1. Not sure if it is using DTR/DSR or RTS/CTS flow control however. Because I am using Virtualbox on both a Mac Intel Core2Duo and a low cost (old POS...
I did a tech video on this, I disassembled the board and show its guts on YouTube. It appears either the RESET line of the 68000 processor is staying active low. The clock is not starting. Here is the link, warning. gets a bit long though as it get to non board issues in the end.
No matter...
The irony is the processor has a Admin port however. At least mine does. it also has that VME bus connector where the PCMCIA card slot would be. Clearly, the designers were planning on a windows/dos SPM for this model. Even my manuals mention that there was a SPM for this.
I wonder if the...
I sent them a message I do hope they will take me up on my free offer. I am willing to release a port for Linux and Mac OS-X. for both PowerPC and Intel based macs.
I am using it on my iMac Intel Core 2 Duo using VirtualBox with FTDI USB to RS232 dongle. works fine. but we all know that the computer world is a very rapidly changing place. I also have an old Pentium 233 mmx machine with windows 95 and Msdos 6.22 and have both versions on that as well.

What type of button cells? Do you have any idea of the type of battery and voltage? One board on Ebay showed button cell like clips and the others show two green NIMH button batteries. I do not know if those NIMH cells are soldered to the board. The green "batteries" did not appear to be in a...
Looking at the same board on Ebay without the clamshell,. it looks like there is TWO Nickle Metal Hydride 3.5v cells soldered to the PCB. Only the picture does not clearly show the mah of the cells. Since my board in in the Merlin Legend Clamshell, looks like two 3.6v 500mah cordless phone NIMH...
Avaya/Lucent/At&T used to have a IS-II/III port of SPM. While The Dos/Windows version works great in virtualbox for both the DOS 7.14 and the WinSPM9. I would like to create a Linux native application as well as one for mac OSX for both PPC and Intel macs. Who has the source code and/or the...
I would personally recommend a 012 board with Ring Generator or ideally a 008OPT board as it is outside of the main building. The BTMI is not ideal for this application at all. the Off Premises Telephone Board with Ring Generator was designed for this exact application.
I also would consider...
I got my old Merlin II processor with R3 laying around that went kaput. Red light stays on and never turns off. That is why we upgraded to the Merlin Legend/Magix CKE5 Processor.
I removed the rechargeable battery and it still won't boot. Replaced several capacitors and again nothing.
I...
I bought a second hand Merlin Magix CKE5 Processor with R7 V14.2. Works great... but..... it is old and I want to avoid any downtime. it is mounted in a Merlin Legend clamshell case as my phone system is an upgraded Merlin II backplane. Still says on two stickers "Void warranty if removed"
Does...
