In addition to typewriters, I have been collecting vintage computers, teletypes, terminals, and a few other accessories for a while. Here is the current collection.
Vintage terminal collection
As of March 2026, I count 9 teletypes/terminals, if I include what might end up as parts machines. The earliest terminals are electromechanical, including the famed Model 33, while the later ones are fully electronic (and sometimes called “glass teletypes”).
1969? - Teletype Model 33 ASR. This instance is being restored as of 2026. Model 33 was made between 1962 and 1976. Some capacitors have date codes staring with "9", which might indicate a 1969 manufacturing date. Before | In progress 197x - Teletype Model 33 ASR. This instance might also be restorable. Before 197x - Teletype Model 33 ASR, made in Canada. This instance will probably have to be a parts machine. Before 197x - Teletype Model 33 RO. This is a read-only version of the famed Teletype Model 33. While bought "for parts", it should be repairable. Before 1979 - TeleVideo TVI-912. This terminal has been fixed and restored in 2023. Before | In progress | Restored 1980? - VT100 Terminal Model NB converted to AB. This means that this is a 230V model, probably used in the UK. This instance needs fixing. Before 1982 - Pair of VT100 Terminals. Both need of fixing. So far they only underwent a basic cleaning. In progress 1983 - TeleVideo TS-800A. This is in working condition as a terminal. This should also work as a diskless CP/M computer, but the CP/M functionality has not been tested as it needs a very specific setup to be able to boot. Before | In progress | Restored
Vintage computer collection
The small collection of about 20 vintage computers includes personal computers from around 1979 to 1993, with a few Apple machines from the 2000s. Most machines are microprocessor-based, with the possible exception of the Wang CPU, which is based on TTL logic (but does include at least one Z80 CPU for I/O!). The most uncommon units here might be the NEC TK-80, the CompuPro System 8/16, the Wang 2200MVP, and the Smaky 130 Swiss computer.
1979? - NEC TK-80. This "NEC μCOM Training Kit TK-80 is an 8080-based single-board computer. Chips have date codes between 1977 and 1979. This was originally released in 1976. This instance features an IBM sticker, which indicates it might have been used at IBM for a while. Before 1981 - Apple II Plus. This has been refurbished, except for the floppy drives. It is now fitted with an Apple Monitor II, which I refurbished, and a Floppy EMU. In progress 1981? - Radio Schack TRS-80 Model III. This instance has breaks in its outer case. It came with a printer, some kind of acquisition device, disks, and manuals. In progress 1984 - CompuPro System 8/16. This incredible S100-bus system includes a 80286 CPU board. It needs refurbishing. Pics 198x - CompuPro drives. These drives were bought separately from the system above, but should be compatible with it. Pics 1983 - Canadian NABU Personal Computer. This machine was ahead of its time. It got into the spotlight in 2023 when a large lot of them was offered for sale on eBay. It turns out that I got one from this lot, but second hand. The machine is new in its box. A community has developed online to revive the machine and its software. Pics 1982? - NorthStar Advantage Pics 1981-1983 - Osborne 1 Pics 1981-1983 - Osborne 1 Pics 1980-1985 - Commodore VIC-20. This machine was cleaned and fixed, and is now in working condition. I built and fitted it with a Sidekick20 cartridge. Before | Sidekick20 | Blog post 1984 - Wang 2200MVP. This is only the CPU part of this amazing computer based on the BASIC programming language. This machine needs to be refurbished. Pics 1984 - Apple IIc. This machine needs fixing. As is, it doesn't boot. In progress 1987 - Macintosh Plus 1Mb Pics 1987 - Apple Platinum IIe. This is the last revision of the Apple II to be put on the market, with 128 KB of RAM and a numeric keypad. This instance doesn't boot and needs work. Pics 1988 - Macintosh SE. This machine had a dead flyback transformer on the analog board. I got a replacement board and that allowed the machine to boot. In progress 1989 - Macintosh SE-30. This machine worked out of the box. I fitted it with a ZuluSCSI disk emulator. Before | In progress 1990 - Atari 1040 STE. This was my own personal computer in the early 1990s, and the first I bought with my own money on September 22, 1990, for CHF 1,490. I only used it with the built in floppy drive, and used it for programming, word processing, and the music program Cubase. 1993 - Smaky 130 color. This rare Swiss computer features a 68030 CPU and a color card. It still needs work. Its keyboard was repaired, and a new mouse provided. It boots in black and white, but needs to boot in color as well. This was my own personal computer for part of the 1990s. In progress1997-1998 - Power Macintosh G32000 - PowerMac G4200x - PowerMac G5
Vintage computer reproductions collection
In addition to originals, I also have a few reproductions. I bought the PiDP-11, as well as the Altair-Duino, as kits. But I worked hard to make the Apple-1 reproduction, in spite of standing on the shoulders of giants.
PiDP-11. This reproduction, based on a Raspberry Pi and the SimH emulator, can run multiple of the original operating systems running on the original PDP-11. This picture shows it connected to a real Televideo terminal and running Unix. Apple-1. I built this reproduction of an Apple 1 between 2024 and 2025. It is fully functional, including the tape drive. For more, see my series of blog posts. The only missing part is a case, which I'd like to be at least partially transparent so that the main board can be seen.Altair-Duino. This reproduction, based on an Arduino Due board, emulates the front panel of an Altair 8800. Here, the Altair is connected to the Televideo terminal and is running WordStar on CP/M! The PiDP-11 is seen on top of the Altair-Duino.
