 Overview 1
Here you see one of my Atari Mega STs, the Samsung SCX-4726FN multifunction device (printer, scanner, fax) and two TFT screens. The IBM 9516-B23 monitor is connected to the RS6000 7011-44 workstation. The NEC Multisync LCD 1770NX supports sync-on-green and is used for the Digital AlphaStation, Digital VaxStation, HP 9000, IBM RS6000 7248-133, SGI Indy, Sun Blade 100, Sun Sparcstation 20, Sun Ultra 10 via an 8-port KVM switch, the second input is connected with an old Commodore 486-33c PC.

For some time I also used an HP A4033A Trinitron CRT monitor (19", 1280x1024@75 Hz) and older fixed-frequency workstation monitors, like an HP 98754A (19", 1024x768@75 Hz and 1280x1024@62 Hz) or an HP A1097C (19", 1280x1024@70 Hz). These monitors require sync-on-green, but you can connect them to a PC via an adapter.

In the upper part of the picture you see my Denon UDR-77 micro HiFi system (tuner, CD, tape) and a Dell C1760nw colour laser printer. You can also notice my video equipment, consisting of a Sanyo VCR, two Pioneer DVD/HDD recorders and a Satellite Receiver.

On the right side you see a Philips 15PFL4122 LCD TV which is used for watching video and TV. It is also connected to the Apple 2c, Commodore 128D, Commodore Amiga 500 (via Amitek MAMBA TV adapter), Commodore Amiga 1200, the Philips MSX2 computer and the Schneider CPC 6128 via an analog video switch. I also use it for the Acorn Electron, BBC Micro, BBC Master, Atari 800XL, Commodore SX-64, Philips P2000T, Sinclair Spectrum +2, my Sinclair QL and the TI 99/4a.

In the center you see my Acer KA220HQ TFT monitors (21.5", 1920x1080), used for the Medion Intel i5 PC, Skybay Intel i3 PC and as external display for the Samsung Galaxy Book Pro. One of them is also connected to the Acorn A3020, Acorn RiscPC, Atari Mega ST, Commodore Amiga 2000 (via Scart2HDMI converter) and the NextStation Mono via a KVM switch.

Here you see my Sanyo VHR-899 VHS VCR (digital still, digital zoom, digital picture-in-picture), the Philips MSX2 computer and the Pioneer DVR-520H DVD/HDD Recorder (80 GB HDD, Disc History, Time Shift, 32 Recording Timers, High Speed Copy, One Touch Record, VPS/PDC, Show View, Commercial Skip). The second DVD recorder, a Pioneer DVR-540H with 160 GB HDD, is not shown.

My second CBM 8296-D was missing the keyboard and had a broken monitor. Therefore I created a custom editor ROM (for socket UE8) supporting the C64 keyboard and CGA/NTSC video timings. Now I can connect a custom built C64 keyboard and an external monitor (either CGA/MDA or Commodore 1084S in RGB-TTL mode), using the PET/CBM video adapter. Additionally I built a simplified adapter for MDA monitors, connecting directly to the internal video port. Using both adapters simultaneously allows dual-monitor operation (obviously showing the same content on both screens).

My second SX-64 was missing the keyboard, hence I had to adapt a regular Commodore 64 keyboard. I cut off some unnecessary parts at the side of the circuit board, so that the keyboard width is adequate for the SX-64 case. Then I built a custom housing for the keyboard in the style of the original SX-64 keyboard. Finally I modified the keyboard connector at the bottom of the SX-64 so that a regular DB25 cable can be used. It took me quite a few hours, but overall I am satisfied with the result.

By chance I recently got hold of a rare CP/M module for the SX-64. It came without software, but I found everything that I needed as download. All steps and tools are described in my summary.

OS: IBM AIX 3.2

I have a second RS6000 7011-44 with 48 MB RAM and 1.0 GB SCSI HDD running IBM AIX 4.3.3. As AIX 4.3.3 does not support the Gt1 graphics adapter, the machine can be used via remote terminal only.

Norbert Kehrer is providing an information library and a videotext server emulation software. To connect the Mupid to a Windows PC running the server software, you need a special serial cable (any standard serial crossover cable will work on Linux).
To use a Raspberry PI as CP/M server for the Mupid, you can use the attached Mupid_PI Toolkit.

An excellent information library is available at Z80.EU. A software archive and PC transfer toolkit can be downloaded at Daves Old Computers. I created a working set of disk definitions for both disk formats (160 KB SS/SD and 640 KB DS/DD) to be used with 22DISK. 22DISK can be downloaded from Gaby.de or Li-pro.net.
My second P2000C only had one floppy disk drive, hence I added a 3.5" HD FDD as second drive. Any drive should work without modifications, supporting 160 KB and 640 KB formats using plain 3.5" DD disks.

My MZ-80B is equipped with the MZ-80RM memory expansion (32 KB) and the MZ-80EU extension unit (holding the MZ-80FI floppy disk interface plus the MZ-8PB5I printer interface). As I am missing the VRAM extension (MZ-80GM hi-res graphic card), the computer displays only 40x25 or 80x25 text. The MZ-80FB dual floppy disk drive stores 280 KB per disk (DS/DD with 70 tracks and 16 sectors/track).
The embedded CRT of my computer just displays a horizontal line, it seems that the vertical deflection circuit is not working properly. Therefore I connected an external VGA TFT monitor via GBS 8200 CGA-2-VGA converter (see external TFT for MZ-80B). This is easy to do, as the MZ-80B provides all necessary signals on the mainboard (video connector with pin 2=combined H&V sync, pin 3=video, pin 4=GND).

My P1 has been upgraded with additional memory and a second FDD, official model name is now TA P2-3A. It uses 80 KB FM disk formats, based on the WD FD1771 disk controller and EPROM version 011 (instead of the WD FD1791 controller with ROM 42D used in later machines). When upgraded with a newer controller and EPROM, it can also run CP/M (exactly like the later P2 machines).

My second TA P2 is a late model with MOS EPROM version 14I, the other model is running version 14G. I have a working DRH-136 printer (9 pin matrix printer, A3 format, serial connector) for this system.
I also got components of another TA P2, unfortunately without the case. Therefore I put the drives, backplane and cards into a PC tower case, now I have a really unique TA P2 Tower.
Additional information and documentation regarding the P2 is provided by Helmut Wiertalla.
