I had a Falco TS-1 dating from ca. 1981 in my possession a couple of years ago and dumped the ROMS. It was based on a Z80 with 6845 CRT controller and 2651 UART. I have data from two 2732s (Z80 firmware), as well as an EA8316 (2K*8) used for character generation. That's in text format. Also have a PDF with some notes on the hardware and reverse-engineered schematic segments. I didn't have need / get as far as doing an I/O map or memory map for the Z80. Should I send these files along?
Re: Battery warning in Falco terminals
Just had a closer look at the TS-2624 and it does indeed have the battery on the board; looks like that's one of the differences from the TS-1x. Looks like I or someone had enough foresight to remove it from this board before it caused any damage. m

The TS-1s and TS2624s were very similar but certainly not the same board. I've also got some of the newer Fame style models; guess I should look at those but if they have the pox then it's probably too late. FWIW, I've also got a bit of documentation for these and various other Falco terminals (User, programming & service) but alas, not for the 2624; I can also certainly dump any firmware that I have. mike

Battery warning in Falco terminals
I've been helping the MAME guys simulate a TS-2624, which is a block mode HP emulating terminal. I had bought this a while ago, and never dumped the firmware. Unfortunately there is a large NiCd battery right in the middle of the board that leaked all over. I've taken some pictures which are up under falco on bitsavers. If anyone has one of these, you want to do battery mitigation ASAP. I'm in the middle of replacing every socket on the board since they were all within range of the leakage corrosion. Also, I suspect the first generation of terminals all have similar hardware with different firmware, so if someone has any of the other models (TS-1, etc.) we could get them simulated pretty easily once the firmware is dumped.
Re: What is windoes doing?
Actually, I do use it almost exclusively with classic machines. I use the RS232 to load and talk to my Nicolet 1080 ( a late 1960s to early 1970 ) machine. I just got done using it to repair a North * Horizon. If I'm leaving trails behind me that I can't get rid of, each time I use it as a terminal, I'll be limited on what repairs I can do. The FTDI was just recently used to write and debug code on a small controller board to convert a ps/2 keyboard to parallel for my Poly88. Windows is not the end use. I don't even put it directly on the web. It is primarily used a data transfer, some editing and terminal for classic machines. Its functioning is important for maintaining and restoring classic machines. This was not a typical " please help me fix my PC " post. I don't email, web search or anything else with this machine. Its one purpose is related to restoring and maintaining classic machines. It is no more off topic than a new temperature controlled soldering iron is. What would I use serial and RS232 for?

Re: What is windoes doing?
Hi Ethan That is entirely possible. I do think about it when I plug and unplug the USB floppy drive but not usually for the serial. Is there a way to finish them or maybe stick things in so that I can "safely remove" things? Most of the time for serial, I use a FTDI but I do have some older USB to RS232 voltage converters as well.

Actually, in the aforementioned environment, it's not really possible to return without a code. The relevant register will contain some value, whether you set it or not. The famous bug in IEFBR14 was that it failed to set that return code, so the job often aborted due to whatever garbage was in the register. De

I've added emulation of most of the functionality of the 98550A 1280x1024 8bpp card. That makes now a nice virtual HP-UX for playing! :-) I'm now on the 4xx Systems - got a bootrom from someone which looks like a 400t Boot ROM - it expects a 68030. As you have a real 4xx, would it be possible to dump the boot rom + configuration eeprom? If you don't have the possibilities to dump it physically, it might be possible via /dev/mem in HP-UX, if someone on the list knows the details on how to use that special device. Best regards Sven

Jim I believe the package internal to mvs / OS has the preface of IND for the modules. Similar to IFBR14 is part of the IFB suite of programs. IFBR14 if you all are not familiar with MVS / MVT batch programming is a program which immediately terminates w/o any return codes by doing an assembly language return to the caller of the job step via the contents of R14 of the processor, which is also the return address. If you needed to do a bunch of JCL but not really run a program to accomplish something, but the JCL or programming required a "program" to execute, IFBR14 was the program used to do that. Anyway, I think from my foggy recollection that there are other IND something modules which comprise the full package of which IND$FILE is a part. The module naming convention was frequently extended to the VM environment which is where I used it most frequently. It was also used with SNA connections to transfer files as well (as a protocol) similar to the xmodem and the like protocols were used with async data transfers. thanks Jim

Re: What is windoes doing?
Every time you unplug and re-plug a USB serial cable you cause the system to create a new IRQ address for it, called COM5, 6,7,8,9 etc. If you do the thing where you "remove usb devices safely" routine you can avoid this. b On Mon, Nov 19, 2018 at 12:13 PM geneb via cctalk wrote: > On Mon, 19 Nov 2018, Ethan via cctalk wrote: > > >> I have a question.

It would be helpful to know which 3rd party programs support the IBM adapters/API as well.
