If it operates like a real PC, DOS reads the RTC only once at boot up and then keeps track of the time and date itself in reserved RAM locations using interrupts. Using the TIME and DATE commands to read the time and date will use the current DOS values from the RAM locations rather than the RTC...

Looking for a Casio MD-120 floppy drive for use with a Z-1. Working preferred but will consider all.

Here's the CI-7 Cassette Interface if anyone is interested. The other end of the cable just has the usual connectors for a cassette recorder.

I'm looking for any Texas Instruments TI-95 accessories such as the PC-324 printer CI-7 cassette interface CM-8 8K or 32K RAM modules PA-201 power adapter, etc. If you have any TI-95 accessories you'd be willing to sell to a US address, please let me know. I'll pay immediately via PayPal

I'm looking for either a physical copy or good quality scan of the manual for the Video Seven VRAM II Graphics Card. I know there are compatible cards out there but I'd really like to have one specifically for this card. If you have one, please let me know! Thanks.

I'm looking for any information on the Magnetic Peripherals BR8B2A 5.25" floppy drive. This was used in IBM PCs for a while so it's probably compatible with the Tandon TM100-2A but I'd like a manual specific to the drive itself. I checked bitsavers but no luck. If you have a manual or scan I...

Looking for an Altair UIO serial card/cassette interface used in the MITS Attache computer. Manual and cables would be a big plus!

Looking for the Altair UIO serial card/cassette interface that was used in the Altair 8800 Attaché system. If you have one you'd be willing to sell or know where I can download a manual for it, please let me know! Thanks! Tom L

I have a Centronics HPC-136-3B printer and it runs the self-test just fine. It has both a parallel and a serial port and right now it seems like the parallel port is the active one but I need to use the serial port. I see a couple banks of DIP switches inside but no legend as to what they do...

I have a MicroDrive Turbo IDE interface in my Apple IIe Platinum. I has an adapter to allow two CD cards to be plugged into it. I have two cards that each work fine when they are the only card plugged in but when I plug both of them in, I get the message, "Volume not formatted" Does anyone else...

Does anyone have any information about the Wang 3300 minicomputer other than what's at wang3300.org? That was the first real computer I ever saw (I programmed in FORTRAN before that but never saw the mainframe I was creating card decks for) and it will always hold a special place in my heart...

I have a QDI P5I430VX 250DM Explorer II SpeedStep motherboard with a 233MHz Pentium MMX processor and 128Mb EDO RAM. On it there's a connector for a Turbo LED but there's no connector for a Turbo switch and no instructions in the manual on how to activate turbo mode. I've looked through the...

I'm trying to create TRS-80 floppies from my Dell XPS 8700 (Core i7) PC using .dsk files downloaded from the Internet. I have a hardware board known as Kryoflux installed. What I'm doing is using the HxC floppy drive emulator to read in the .dsk file (the .dsk file works in the TRS32 emulator)...

I have a 16K Model I with 32K EI (total of 48K), Radio Shack lowercase mod, RS, double density mod and RS cassette mod. The EI is the latest version with no buffered cable or pigtail cable. I have BASIC tapes that I made myself. I can read them just fine in Level II BASIC at almost any volume...

I have 32K cartridges for the TI-74 but can't use all the memory without MEMADD.SUB. Can anyone direct me to a Website that has it available for download or send it to me via email? Thanks! Tom Lake
