I took a look at the PCjr to CGA monitor adapter and it is a stubby little thing. It's probably a good idea to add an extension cable just to protect the pins and plastic separators.

What is the 6' DB9 cable for? I must be missing something, The PCjr to CGA cable plugs into the DAC. The DAC uses the 6 wire molex to send signal to the GBS-8220 (and two wire molex for power). The VGA cable plugs into the GBS-8220. What am I missing.?

Does the DAC come with any instructions?

Norton is wildly optimistic. I would say the V20 @ 4.77 mhz, more or less, gives the PCjr back the speed that video circuit robbed, making it about the same speed as the XT.

That chat was really fun. Hope you schedule one again

I think so. Some mid to late 80s games had mouse support. The SCI Sierra games had mouse support. Lotus 123 (v2?) and Professional Write had mouse support.

Any 8 or 10 Mhz one should work as well. The speed rating is the maximum speed. Standard V20s have the same form factor as the 8088.

I am using a 128 MB DOM and a 32 MB DOM so smaller DOMs work. I want to upgrade to a 512MB eventually. I think they go for about $15

Congratulations on the new job. It's been quiet but I usually check the forum daily. When someone does post a question there a usually atleast a few responses. Everything is running great with the PCjrs. I plan to upgrade the jrIDE from a 128MB DOM to a 512MB one. One quirk with the jrIDE is it is n...

VB/DOS? Wow, I haven't spun that up for ages. There is a full copy buried out in the garage somewhere, but I think the install floppies are 3.5" and may be high density. VB DOS was painfully slow and I don't know if it would work without the Combo Cartridge. I uninstalled it almost immediately...

A bit of bad news My PCjr has the PC Enterprises Combo V2 cartridge. Among its features is a keyboard buffer and some Keyboard bug fixes. If I remove the cartridge I get the same results as you did on both QuickBasic and QBasic. Sorry. I recently spoke to the the people that used to own PC Enterpris...
