    I use the serialdisk image in SIMH as the second RK05 and boot from an RK05 image that works under SIMH. That way I don't have to worry about the handlers that are installed on the serialdisk image.

    I use serialdisk to copy files from the RK05 on my 8/e to/from a disk image on my desktop machine. Then I can use the disk image with SIMH.

    We have the TTY working, including the paper tape reader control. We put a 10-pin Molex with the DEC VT220 pinout on everything that supports 20mA current loop so we can swap consoles between the...

    And that it what makes it really useful. Reading and writing DECtapes that didn't come from a PDP-8 is easy.

    This is a little project that I did with the 8/L at the RICM. I connected a Smart-Fusion FPGA to the I/O bus and the 8/L thought that it was a very fast paper tape reader. It would load FOCAL in...

    I think that it is worth a try. The EAE boards are useless to me otherwise.

    My 8/e has the newer CPU boards, and I have an older set of EAE boards. I plan to disconnect the edge contact from Ground and connect it to RESTART so I can add EAE to the 8/e.

    We plan to demonstrate the Altair with MITS 4k BASIC, so we will need working RAM.

    The Rhode Island Computer Museum just received a MITS Altair 8800 and ASR 33 Teletype as a donation.

    With some cleaning and fiddling it is now working. We plan to punch a 4k BASIC paper tape and...

    Your repairs look very similar to what was needed for the RICM's PDP-8/L. We replaced less diodes, and more SN7474 ICs.

    With the SN7453 and SN7460 parts it can be difficult to determine which one...

    I have been running two RK05 drives without the nicads installed. I understand the risks, and have new batteries, but have not installed them yet. They seem to work fine without them.

    Doug,

    We installed the third TU56 yesterday, removed and polished the tape guides, and replaced the Integrating One-Shot. The drive works, but is not 100% reliable yet. Still some work to do.

    We added a second TU55 DECtape drive to the PDP-9, and need to add a third in order to use MACROI and F4I. These compilers have fixed I/O device assignments in order to save a little core and run on...
